1 Introduction
1.1 Purpose
The purpose of this manual is to provide the information required to enable the end user,
customer and installer to successfully install the Z12Mk4 antenna and controller and to
program the KA-190 for operation.
It is recommended that all personnel operating the Z12Mk4 systems know which type of
system they are dealing with, read and understand the basic terms, and are fully familiar
with the operation of these systems.
Although installation may be completed by personnel preferred or designated by the
customer, it is also recommended that personnel be trained in the KNS for more suitable
equipment installation procedures, and trained by KNS Inc. experts in the relevant matters.
Section 2 of this document has been provided to ensure that ALL personnel are aware of
the specific safety hazards involved in the installation and configuration of the KNS
equipment (e.g. electrical, static and RF radiation hazards).
1
2 Safety
2.1 Radio Frequency Radiation (RFR) Hazard
According to NASA and FCC, Excessive level of RFR (Radio Frequency Radiation)
exposure may cause harmful result in adverse (immediate) effects on people such as
involuntary muscle contractions (electro-stimulation), electrical shocks/burns (from touching
metal objects in RFR fields), and excessive heating of tissue (thermal damage). The VSAT
satellite antenna system can produce high-intensity radio frequency radiation environments
that are potentially hazardous to operating and maintenance personnel. Radar and
communication systems, which use high-power RF transmitters and high-gain antennas
represent a biological hazard to personnel working on, or in the vicinity of, these systems.
The detrimental effects of overexposure to RFR are associated with an increase in overall
body temperature or a temperature rise in specific organs of the body.
RFR Effects only possible at ten times the permissible exposure limit

and
maintenance technician have full responsibility for the safety.
During transmission, all maintenance personnel must maintain
a minimal distance of 25m(82.4ft) from the front of the reflector
with 8W BUC. Service personnel can access the ADU without
being exposed to the radiation hazard by accessing it from below
the Antenna base.
2.2 Recommendation
Access to the immediate vicinity of the antenna (reflector and feed) must be restricted to
trained customers and certified contracted/service personnel. No member of personnel
should interpose any of their body parts between the feed and the reflector while the
terminal is transmitting. At full output power, this region is dangerous in cases of exposure
of more than about 14.6 seconds.
At full output power, the near-field output of the auto acquire terminals exceeds the
allowable levels for continuous exposure in an uncontrolled area. This near field is a
cylindrical region which encloses the reflector and points toward the satellite. Because
many sites accommodating the auto acquire terminals are accessible to non-operational
personnel, these sites should be considered as uncontrolled and the recommended
precautions taken accordingly.
The primary precaution should consist in restricting access to the immediate area in front
of the reflector to short durations, which, according to worst-case assumptions, means that
access should be limited to less than 10 minutes within any 30-minute interval.
2.3 Safety Precaution
ADU module is sealed unit. This unit should be closed under any circumstances.
The antenna radome assembly should be rigidly mounted on the boat. If necessary,
reinforce the mounting area to assure that it does not flex due to the boat’s motion or
3
vibration.
Environmental: must operate in controlled environment (temp, altitude, dust, vibration,
corrosive, explosive free)
EMC (elective magnetic compatibility): to ensure the antenna system provides the
highest protection against interfering. The antenna should be 5m away from other
transmitting antennas such as HF, VHF, and radar.
Cable must be shielded and all equipment must be covered
During the hoisting, the system has to be balanced. Swaying radome assembly may
cause personnel injury or damage to the system.
Note :
Moving parts!
“Keep body parts away from moving parts”
Inside the radome are moving parts. Therefore, only skilled or certified persons are
accessible. The operator should pay attention to the following when working.
“Disconnect the power source prior to defeating or bypassing the equipment
safeguard(Enclosure)”
“Restore the equipment safeguard(Enclosure) before restoring power”

3 Installation
3.1 Site Selection
Determine the optimum mounting location for the antenna radome assembly. It should
be installed where:
1. The antenna has a clear line-of-sight of as much of the sky as is practical.
Choose a
location where masts or other structures do not block the satellite signal from the dish as
the boat turns.
2. The antenna is at least 5m away from other transmitting antennae (HF, VHF and other
VSAT antenna) which may generate signals with the potential to interfere with the
SuperTrack Z series antenna. In case of radar, the distance from the center of the radar
beam should be more than 10m when the antenna is install within the radar’s beam.
Otherwise the distance from the center of the radar beam should be 3m away from the
antenna. The further away the SuperTrack Z series antenna is from these other antennas,
the less likely is it to be affected by their operation.
3. The antenna radome assembly should be rigidly mounted on the boat. If necessary,
reinforce the mounting area to assure that it does not flex due to the boat’s motion or
vibration.
Figure 3-1 Installation Location

3.2 Unpacking
Open the wooden box using pliers and remove the packaging material carefully. Lift the
unit out of the box carefully. Do not turn the box and “roll” the unit out, or turn the box
upside down to remove it. Be careful when unpacking the equipment.
Figure 3-2 Antenna Wooden Box
6
Remove the bolts and bracket used to protect the antenna from shipping damage after
opening the radome. If power is supplied to the antenna without removing the fixed parts,
the antenna may be damaged.
The antenna should be secured using the fixed parts during transportation by truck or
another vehicle. So please keep the fixed parts in the event that the antenna is to be
moved to a different place or ready to be installed after ground testing.
Figure 3-3 Antenna Fixed Part
7
3.3 Installing the Equipment Cables
The SuperTrack Z12Mk4 comprises two major sections: The Above-Deck Equipment
(ADE) is composed solely of the antenna radome assembly, which is mounted outside. The
Below-Decks Equipment (BDE) includes the Antenna Control Unit (ACU), satellite
modem(s), and all other items of ancillary equipment.
The ADE is connected with the BDE by two coaxial cables; the type of cable to be used
depends on the length of cable required.
NOTE: Unused coax connections (on the connector bracket) MUST be terminated with
a 50 ohm terminator.
NOTE : One power cable may need to be installed according to options as heater or up
to 10W BUC.
NOTE: We recommend cable type according to cable length, as follows:
-within 20m: RG213/U
-within 40m: RG8/U
-within 80m: LMR400
-within 120m: LMR600
-within 180m: LMR900
-within 250m: LMR1200
NOTE: Impedance of cable is 50ohm. Also the other cable types can be selected.
However we recommend all attenuation of cable is under 20dB at 2.5GHz.
NOTE: When installing the cables, avoid the use of excessive force. Exercise caution
during installation of the cables to ensure that they are not severely bent (within the
assured bend radius), kinked or twisted, and that the connectors are not damaged.
NOTE: Make sure that the cables have been passed through watertight fittings and/or
that they will prevent water from entering the ship once their installation has been
completed. After the cables have been routed and adjusted for the correct cable length at
each end, seal the deck penetration glands and tie the cables securely in place.
NOTE: Must be installed the N type connectors on the two coaxial cables. However if the
TX cable is directly connected with TX port on the modem, the connector type depends on
the connector type of TX port on the modem.

3.4 Mounting the Antenna Unit
3.4.1 Prepare the Support Post
Prepare the antenna support post for the radome. The radome must be bolted to the
support post plate. Make sure that the mounting holes have been drilled. Please refer to the
Appendix C for detail drawings.
Make sure that the antenna support post is painted appropriately for anti-corrosion.
Thread the TX and RX cables from below deck up through the cable access hole on the
deck. (Check the number of RF cables required).
The support post should be upright. Check the post angle carefully prior to welding the
post base to the deck. If it is uneven or not level, weld the clips to the plate or place the
foam seal in position on the mounting surface.
Refer to Fig 3-4 below. The thickness and size of the support plate can be changed
according to the height of the support post
Figure 3-4 Diagram of a typical Antenna Support Post (Unit mm)

3.4.2 Hoisting the Antenna
Refer to the specifications and drawings for the fully assembled weight of your model
antenna and ensure that the equipment used to hoist this system is rated accordingly.
The antenna assembly is very light for its size and is subject to large swaying motions if
hoisted under windy conditions. Always ensure that the tag lines attached to the radome
base frame are properly put while the antenna assembly is being hoisted to its assigned
location aboard the ship.
Ensure that the antenna is secured before hoisting. Check that all the nuts on the base
frame assembly have been tightened.
Using four-eye nuts, and with a tag line attached to the radome base frame, hoist the
antenna assembly to its assigned location aboard the ship by means of a suitably-sized
crane.
Figure 3-5 Hoisting the Antenna
10
Position the base plate in place over the mounting holes and the cable access hole, and
then align the radome base’s “Bow” label (as shown in Figure 3-6) with the ship’s bow.
Figure 3-6 Positioning the Radome
11
Figure 3-7 “BOW” Label of the Radome Base
NOTE: If cannot align the 'BOW' label with ship's bow, must readjust the antenna offset
after installation. Please refer to the section 5.2 for details.
3.4.3 Installing the Radome Assembly
Install a flat and spring washers(Ø12) and a mounting bolt(M12) (supplied with the
product) to each mounting hole of the radome base from the underside of the mounting
surface. Apply Loctite which is provided as the installation kit to the threads of the mounting
bolts up near the mounting surface and tighten each of the 4 bolts to 24 in-lb (21 kg-cm)
torque [finger tight, then about 1/4 turn tighter] with a wrench.
DO NOT OVER-TIGHTEN. If the mounting bolt provided is too short or long, you will
have to install mounting bolts of the appropriate length.

3.4.4 Installing the Cables
The radome base has two holes for each cables, and each cables were installed the
cable gland(PG21, cable range 13~18mm) as below Figure 3-10.
Figure 3-10 Typical Cable Gland
Thread the TX/RX cables through the cable access holes and connect them to the
connectors of the antenna. Check the labels on both ends of each RF cable to make sure
they match the radome base plate connector. Do not use Teflon gel on the cable fittings as
it reduces signal strength at high frequencies.
Figure 3-11 Connecting the TX/RX Cables
14
Figure 3-12 Antenna on the Support Post
NOTE: If the antenna is to be fixed after conducting the ground testing, you have to
remove the fixed jig after installing the radome assembly. If you do not remove the fixed jig
and then supply power to the antenna, the antenna may be damaged. Please recheck
whether the antenna is fixed or free before supplying power to the antenna.
15
3.5 Mounting the Antenna Control Unit (ACU)
Install the ACU in front of a standard 19” equipment rack or other suitable location. The
following are the recommended conditions for the ACU’s location.
The ACU should be placed in a dry location that is convenient for the user. It must not be
susceptible to magnetic interference nor be situated on a level surface. It should be placed
so that the VFD is visible and the buttons are accessible. Allow sufficient room at the back
to connect all the cables to the rear panel.

when the PSU of KA-190 ACU is used as BUC power.
The TX Out connector(N type female) is connected to the TX port on the antenna and
supplies 48V DC power and sends TX L-band signal with 50Mhz(or 10Mhz) reference
signal to the BUC when the PSU of KA-190 ACU is used as BUC power.
Figure 3-21 RF interface ports on KA-190 ACU
3.6.2 ACU Cable Connection
The cabling between the above-deck equipment (antenna pedestal) and the below-deck
equipment (ACU) only requires TX and RX L-band coaxial cables of a type that will be
determined during the installation process (based on the length of the cable required).
It is strongly recommended to run the cables directly from the antenna to the ACU,
thereby dispensing with the need to go through any IF patch panels to provide the best
signal level for viewing.
It is important to keep these cables the grounded (outer shield of the coax cable) isolated
from any other groundings due to the sensitivity of the CMOS components of the PCU.
A good rule of thumb is that the receive (RX) L-band cable be directly connected to the
antenna control unit. This is because the receive (RX) L-band cable provides the DC power
23
to the PCU to operate that antenna. Technically speaking, the grounds from the TX and
RX IFL runs can be different, but a single piece of cable running from the ACU to the
antenna will ensure that the antenna operates properly and protect it from a possible 48
VDC, which supports the optional BUC installation.
Depends on the network setting on X7 modem, the external switch is not necessary. In
that case, the Ethernet port on the ACU is connected to the a port on the X7’s Ethernet
ports.

3.6.2.1 ACU Gyro Compass Cable Connection
The KA-190 ACU will accept Synchro, Step-by-step, and NEMA interface data for a Gyro
compass connection.
The ACU is configured with a terminal strip and a DB-15 port. Care must be taken when
completing these connections. These wires may conduct high voltages and can damage
equipment and/or cause personal injury.
For the synchro and step-by-step gyro inputs, the installer must enter the ship’s heading
information on the ACU for proper operation. Also, it is recommended that a validation
25
test be conducted to determine whether the proper heading updates are being received on
the ACU screen.
If the ACU heading is being updated in reverse, the ACU can be modified to change the
polarity of the incoming voltage.
Synchro-Type Gyro Connection
In the case of the synchro-type gyro, uses the 5 pins (R1, R2, S1, S2, S3) of the DB-15
connector or the I/O & gyro strip connector.

3.6.2.3 NMEA Port Connection for GPS Data
The internal GPS is located on the elevation plate of the antenna. The internal GPS
antenna sends correct GPS data to the PCU when internal GPS data is available. Then, the
PCU sends the GPS data to the ACU.
However, if internal GPS data is not available or broken, the internal GPS antenna does
not send GPS data to the PCU. In this case, the PCU sends default GPS data value to
ACU, which is saved data gathered from internal GPS antenna.
The PCU sends the GPS data to the ACU using the KNS own protocol. The ACU
processes and regenerates the GPS information received from the PCU via the DB-9
NMEA (RS232) and the RJ-45 console port.
The format and baud rate of the GPS can be configured as GPRMC, GPGLL or GPGGA,
and from 1200 to 115200 bps, respectively, using the KA-190 ACU. The DB-9 NMEA and
the RJ-45 ports can each have a different format and baud rate. Please refer to the ‘7.2.7
GPS Output Format & Baudrate’ of installation mode for further details.
NOTE: At the first power-on for the GPS antenna, it will take about 5 minutes to
calculate your location from GPS satellite signals and configure the database.
NOTE: If the internal GPS is broken or non-valid, the KA-190 ACU can accept the
29
external GPS signal via NMEA port. But order of priority is given to the internal GPS
signal.
NOTE: If the ship’s gyro is a GPS compass that has a heading angle and GPS data,
the KA-190 ACU can accept the heading angle and the GPS signal via the Gyro
connector (DB-15 pins) at the same time.
3.6.2.4 BMIM
The BMIM connector is used to communicate between the iDirect X7 modem and the
BUC using OpenBMIP. The pins Pinouts of BMIM port is as following Table 3-9. In order to

4 Theory
4.1 Self-Disciplining Algorithm
The greatest difference of the KNS antenna system from other stabilized antennas is its
superbly designed algorithm. Pin-point accuracy can be easily obtained with a spectrum
analyzer during satellite cut-over.
The key reason for this pin-point accuracy is to
guarantee the capacity for self-discipline, whereby the algorithm constantly calculates the
difference between theoretic and real-time values and disciplines itself accordingly. This
algorithm requires very complex computations, and the KNS antenna system uses the 32bit process with 180 MHz of clock when it performs the calculation at nano-second (10-9)
speeds (i.e. a thousand times faster than a micro-second).
The motioning patterns in land-mobile and maritime applications are very different. For
example, dramatic acceleration or deceleration occurs in land-mobile applications, whereas
pitch-roll-yawl motions occur in maritime applications.
Some vendor stabilized systems may have up to two different sets of algorithms specific
to land-mobile and maritime applications. The KNS stabilizer uses a single algorithm for
land-mobile and maritime applications simply because the motion sampling process of the
DSP is far faster than any actual motioning condition.
4.2 Searching and Tracking Reference
Z12Mk4 antenna uses the “tuning” and “fine tuning” methods. Searching is a “tuning”
process which tries to find the satellite by covering a wide range of elevation and azimuth
motions; tracking is a “fine tuning” process which optimizes the pointing by a “Dish Scan”
mode after searching for the signal of the target satellite.
There are six searching references, as follows: DVB Carrier Lock; RSSD Threshold;
RSSD C/N(Carrier to Noise) Threshold; External Lock; DVB AGC Threshold; DVB
C/N(Carrier to Noise) Threshold; And, there are four tracking references: DVB AGC; DVB
C/N; RSSD Signal; and RSSD C/N. The ACU or Web-GUI can be configured by the
operator to function in any combination of Searching and Tracking references.
NOTE: With the threshold searching references the antenna will perform a search pattern
until the received level measured by the RSSD or DVB tuners exceeds the pre-configured
threshold level.
32
4.2.1 Searching Reference
4.2.1.1 DVB Carrier Lock
The antenna searches for the satellite using the preconfigured frequency and symbol
rate, the satellite signal is decoded by the built-in DVB tuner which can support up to DVBS2X.
We recommend a DVB carrier lock as a searching reference if a DVB carrier is available.
The threshold value is not required.
If the antenna points towards the target satellite and the DVB tuner has the correct carrier
parameters, the DVB demodulator locks on the carrier and sets the lock bit on, which
means the antenna is pointing towards the correct satellite, provided that an identical DVB
carrier is not present on an adjacent satellite (low probability).
This requires the DVB tuner to be configured with the correct carrier parameters, such as
frequency, symbol rate and encryption.
4.2.1.2 RSSD Threshold
The antenna searches for the satellite using an RSSD threshold level. RSSD measures a
power spectrum of about 150KHz(±75KHz) at its tuned center frequency and represents
the strength as an RSSD level (higher is stronger).
The antenna “believes” that it points towards the target satellite whenever the current
RSSD level is above the threshold. Hence, the threshold level value should be carefully
selected to ensure the success of the searching process.
4.2.1.3 RSSD C/N Threshold
The antenna searches for the satellite using an RSSD C/N threshold level. RSSD
measures a power spectrum at three points such as center frequency and two noise
points(center frequency – band width/2 and center frequency + band width/2). Then the
differentials between the center frequency and two noise points are reported to the main
processor, eventually the main processor uses the less value of two differentials as the
RSSD C/N.
The antenna “believes” that it points towards the target satellite whenever the current
RSSD C/N level is above the threshold. Hence, the threshold level value should be
carefully selected to ensure the success of the searching process.
33
4.2.1.4 External Lock
The antenna searches for the satellite using an RSSD C/N threshold and the RSSD
threshold level is automatically configured when antenna starts the searching. User can
check the threshold level on the '5' key's function or Web-GUI. And then the ACU is waiting
for the Lock signal from the modem via CONSOLE port or Ethernet port for the “DELAY” of
the 'SEARCHING PARAMETERS'.
In case of the CONSOLE port, the Lock bit state by the logical voltage depends on the
type of modem. In the case of an HNS modem, when the voltage level of the CC is logical
high (2.6~5VDC), the lock bit is considered to be on. Conversely, the iDirect modem’s lock
bit is on when the logical voltage is low. For the specifications of each, please refer to the
modem's manual. In case of Ethernet port, the ACU can receive the RX lock bit from the
modem and it is received by the ABS protocol.
If the antenna can't be received the external lock bits from the modem, the antenna is
changing the searching range from ① to ⑦ as below Figure 4-1.
①
③
②
④
⑤
⑥
⑦
Figure 4-1 Searching Process on External Lock Searching
The antenna is going to the searching fail mode when the antenna is not received the
external lot bits of the modem until ⑦th searching. And then antenna restarts the searching
after 30seconds.
Like the DVB tuner, some external demodulators are capable of generating a lock signal
when the carrier is locked. This information can be used for searching in the same manner
as the DVB carrier lock. However, the response time of the external device between
detecting lock and setting lock on must be as fast as the speed of the Z12Mk4 searching
process.
To keep the response times to a minimum, it is necessary to use a lower value for the
34
acquisition range (no higher than 30 KHz) and a PLL-based LNB (LNB stability should be
within +/-10Khz).
NOTE: A drawback occurs when antenna losses the lock bit is off (logically unlocked)
stemming from the modem. And then, the antenna returns to the searching process.
4.2.1.5 DVB AGC Threshold
The antenna searches for the satellite using the DVB tuner and an AGC threshold level.
The DVB tuner measures a power spectrum of about 1 MHz at its tuned center frequency
and represents its strength as an AGC level (higher is stronger).
The antenna “believes” that it is pointing towards the target satellite whenever the DVB
AGC level is above the preset threshold. Hence, the threshold level value should be
carefully selected to ensure the success of the searching process.
4.2.1.6 DVB C/N Threshold
The antenna searches for the satellite using the DVB tuner and a C/N threshold level. In
order to use DVB C/N threshold searching, the correct frequency, symbol rate and
encryption are required. Otherwise the antenna is not able to get the higher DVB C/N value.
The antenna “believes” that it points towards the target satellite whenever the DVB C/N
level is above the threshold. Hence, the threshold level value should be carefully selected
to ensure the success of the searching process.
4.2.2 Tracking Reference
The tracking algorithm uses selected energy level variations while the antenna scanning
process is on. The tracking process is only initiated when the searching conditions have
been met.
4.2.2.1 DVB AGC
The antenna tracks the satellite by con-scan by reading the DVB AGC level changes of
the desired carrier on the target satellite. AGC level tracking may result in tracking off from
the target satellite, when there is severe interference from an adjacent satellite that has a
stronger carrier level.
4.2.2.2 DVB C/N
The antenna tracks the satellite by con-scan by reading the DVB C/N ratio change of the
desired DVB carrier on the target satellite. The DVB tuner C/N ratio is very useful where
35
there is adjacent satellite interference (ASI). ASI can create a higher energy level but will
reduce the C/N ratio at the same time. The C/N ratio tracking method will not cause the
antenna to track off the target satellite.
4.2.2.3 RSSD Signal
The antenna tracks the satellite by con-scan by reading the RSSD power level of 200
KHz band width of the RSSD L-band frequency. The RSSD frequency is the L-band
frequency of the target carrier, the main processor autonomously calculates the RSSD
frequency using the RX frequency and LNB LO.
4.2.2.4 RSSD C/N
The antenna tracks the satellite by con-scan by reading the RSSD C/N which is between
the center frequency and both edge of band width. The RSSD frequency is the L-band
frequency of the target carrier, the main processor autonomously calculates the RSSD
frequency using the RX frequency and LNB LO.
4.3 Methods of Finding Satellite
Z12Mk4 has four satellite finding methods such as auto searching, manual searching,
manual pointing and standby mode. The user can select the proper method as occasion
demands.
4.3.1 Auto Searching
Auto-Searching is the most recommended searching method. The system runs a builtin satellite calibration program using pre-configured information such as satellite longitude,
ship heading and automated GPS (site) location data, which can be manually entered in
the case of a GPS failure.
The program calculates the EL and AZ values, and then the antenna points to that
calculated satellite position and begins the search process to find the target satellite. After
the searching condition has been met, the antenna enters into the tracking mode.
4.3.2 Standby Mode
The antenna is immediately stopped at the point where user chooses the Standby mode
function. During the standby mode, the antenna doesn’t have the con-scan function.
36
4.3.3 Manual Pointing
In this pointing method, the user controls the antenna manually by entering the desired
EL and AZ. The ACU will not perform any searching pattern but tracking(con-scan) is
always on. This is a handy option, and is used primarily during the initial installation and
troubleshooting process.
4.3.4 Manual Searching
The EL and AZ values are entered manually in lieu of being automatically calculated by
the ACU. The antenna first points the manually-entered EL and AZ values and then
performs the search to locate the target satellite. After the searching condition has been
met, the antenna will automatically enter a tracking mode.
4.4 NIM Searching Reference
Z12Mk4 with DVB-S2X tuner has four NIM searching standard methods: AUTO, DVBS1,
DVBS2, DSS. The user can select the proper method according to desired carrier or just
choose the AUTO. During the AUTO mode, the DVB-S2X tuner looks through all methods
to find the proper encryption.
4.4.1 Auto
‘Auto’ mode spends more time to find the correct encryption because the antenna looks
through all methods using DVB-S2X tuner, however the time difference is unrecognizable.
4.4.2 DVB S1
In this searching standard method, PCU will only search the DVB-S carrier. User must
know the proper system encryption to find desired carrier.
4.4.3 DVB S2
Select this method, if your desired carrier is using the DVB-S2 and DVB-S2X encryption.
4.4.4 DSS
Select this method, if your desired carrier is using the DSS encryption.
4.5 LNB Compatibility
To validate the LNB compatibility, the operator must know the following steps.
RF downlink frequency: If the searching and tracking reference is configured for an
37
RSSD or DVB carrier, then the operator must know the center frequency of the RF downlink (receive) within the proper range.
LNB input frequency range: The LNB specifications sheet or manufacturer’s label on the
LNB usually identifies the input frequency range.
This value can also be calculated from the LNB LO frequency and the output frequency
range.
The LNB stability: The specifications of the LNB usually include its stability.
First, the installer should determine whether:
The RF downlink frequency is within the LNB input frequency. If not, the DVB or RSSD
tuner cannot be locked on the carrier.
If the searching reference is RSSD (narrow band tuner) or external lock, it is important to
use an LNB with +/- 10 KHz stability; typically, a DRO LNB has +/-500 KHz of stability,
which can be problematic at best if the tracking carrier is a very narrow carrier, as in a
beacon and CW carrier. Also, the external modem can’t lock on fast enough with the
installed LNB with +/- 500 KHz of stability, which is also problematic if the external lock is
used for the searching method.
NOTE: The KNS antenna supports a universal LNB. The DC voltage and tone signal can
selects different LO frequencies of universal LNB.
4.6 BUC Compatibility
The block up-converter (BUC) is a device comprising an up-converter and power
amplifier in a single package.
It is important to make sure that the desired transmit carrier frequency is within the
operating range of the BUC. Most BUCs require an external reference(10MHz or 50MHz)
and a DC voltage from the modem or the ACU.
Make sure that the proper DC voltages are provided to the BUC. The equipment will be
damaged if a 24 VDC BUC is provided with voltage of 48 VDC, which is generally used in
larger BUCs. Note that, currently, the ACU only provides 48 VDC through the TX IFL cable.
38
5 Initial Configuration
After installing the radome assembly and the ACU, the Z12Mk4 antenna must be
configured with some parameters to ensure correct operation of the antenna. This section
concerns ‘How to configure the antenna for the first time’. If the initial configuration is
incorrect, it may have a detrimental effect on the antenna’s operation.
5.1 Supply AC Power
During the initial power-up sequence, the ACU provides DC current (48 VDC) via the
receive (RX) L-band cable. The ACU has a built-in short-circuit protection to ensure that
there is no short circuit between the center conductor of the L-Band RX cable and the
shield or other metallic surfaces.

5.2 Alignment of the Antenna and the Ship’s
Bow
We recommend that the bow mark of the radome base be aligned with the ship’s bow for
correct tracking of the satellite. But the ship’s mounting condition usually varies and is
limited, so the installer can mount the antenna in a direction other than the recommended
direction. If the antenna is mounted in another direction, the installer must re-set the
41
antenna offset. Please refer to the steps outlined below to configure the antenna offset.
NOTE: Antenna offset is only required when the PCU compass mode is “NORMAL” and
“MANUAL” mode. The “GYRO FREE” mode does not require the antenna offset. Please
refer to ‘Installation Mode’ to determine the PCU compass mode.
NOTE: Antenna offset only affects the azimuth angle, and has nothing to do with
elevation.

NOTE: Fortunately, most satellites use standard polarity. However, some satellites use a
non-std way of linear polarity. If a satellite uses standard polarity (most US and EU
satellites), it is not necessary for the operator to input the skew offset. However, in the
case of non-standard polarity satellites, the operator must input the skew offset in the
configuration given under ‘S&T Reference Details’.
Go to ‘Polarity’ (Key ‘4’) and search for the polarity angle where the energy level (DVB
C/N, AVB AGC, RSSD) is at its highest, using either the MANUAL or JOG functions. Then,

6.1.6 Searching ON/OFF (Key ‘+/-’)
Searching OFF is a special function to prevent the antenna from going into the searching
process when a searching problem occurs, such as a tracking failure or obstruction of the
satellite signal.
The Searching OFF function is very useful when there are frequent blockages of short
duration. If you select Searching ON, any blockage (exceeded searching delay) causes the
antenna to go searching wherever the searching pattern has been initiated.

ACU is power cycled, and the previous parameters will be restored.
6.2.1 Ship Antenna Offset
The antenna’s heading must be aligned with the ship’s heading to ensure accuracy of

6.2.2 Searching Parameter Setting
The searching parameter is a range which the antenna searches for the satellite from the
position derived from PCU. If it is too narrow, the antenna will not be able to search for the
antenna. Also, if it is too wide, the antenna searching time will be slower than inputting the
proper parameter. Please be deliberate when changing the searching range.
AZI(Azimuth) Range : Searching range (degree) of azimuth axis
ELE(Elevation) Range : Searching range (degree) of elevation
STEP : Increase range in former step
SCH (Searching) Delay : Time-out for automatic initiation of a search when the receving
condition doesn’t meet the configured searching reference such as the signal level drops
below the threshold level or the antenna loses of the lock bit.

6.2.3 Block Area Setting
The signal from a satellite to the antenna is a line-of-sight (LOS) signal which enables
ship structures to block the signal in a certain azimuth angle. When the antenna transmits
during this structural blockage, it may cause harmful interference or radiation. During the
initial installation, the installer can store up to three blocking areas in the ACU flash memory,
from which the ACU can determine whether the antenna is within a block area or not, and
send the TX mute signal through the CONSOLE port, I/O and Gyro terminal strip connector
and Ethernet port.
CONSOLE Port
The ACU sends 0VDC when the antenna is normally tracking and the output voltage
changes to 5VDC when the tracking is unstable or the antenna is within the block area.
I/O and Gyro Terminal Strip Connector
61
The ACU sends a contact-closure (CC) signal via the SW1 and SW2 positions. It is
normally closed (NC) for non-blocking areas. This CC can be used by the operator to
control an RF inhibit function (transmission on or off).
Ethernet Port
The ACU sends the TX mute signal via the ABS protocol when the antenna is within the
block area.
NOTE: The azimuth angle of the block area is calculated relatively to the ship heading.
NOTE: The operator can set the 3 elevation zones and 3 azimuth zones to the block area.

INSTL:AZIMUTH AND ELEVATION TRIM
PLEASE CHECK: COMPASS,GPS,TRCK,MODE...
Figure 6-27 Requirements of Azimuth and Elevation Trim
Azimuth Trim: When the operator selects the ‘Azimuth and Elevation Trim’ function, the
PCU calculates the discrepancy between the calculated azimuth angle and the current
azimuth angle. Then, the PCU changes the antenna offset to the new antenna offset. The
following formula is used to adjust the antenna offset.
Discrepancy of Azimuth Angle = Calculated Azimuth Angle by PCU – Current Azimuth
Angle
New Antenna Offset = Current Antenna Offset – Discrepancy of Antenna Angle
Elevation Trim: When the operator selects the ‘Azimuth and Elevation Trim’ function, the
PCU calculates the discrepancy between the calculated elevation angle and the current
elevation angle. Then, the PCU changes the cage offset to the new cage offset. The
following formula is used to adjust the cage offset.
Discrepancy of Elevation Angle = Calculated Elevation Angle by PCU – Current Elevation
Angle
New Cage Offset = Current Cage Offset – Discrepancy of Cage Angle

6.2.8 PCU Compass Mode
There are four modes, as outlined below. The operator can select the PCU compass type
according to the state of the ship’s gyro. The antenna will start initializing after selection of
the PCU compass mode.
NORMAL (GYRO COMPASS)
Select the ‘NORMAL’ mode when using the ship’s gyro. The ACU provides GYRO info to
the PCU, which the PCU uses for its computation. For Gyro cable connection, refer to
‘3.6.2 ACU Cable Connection’.
GYRO FREE
The Z12Mk4 antenna supports the gyro free mode when the ship gyro is incorrect or
malfunction. The antenna searches 360 degrees azimuth angle when the gyro free mode is
selected. For that reason, the antenna takes the more time to find the satellite than the
67
normal mode.
NOTE : KNS firmly recommends to use the “NORMAL” mode as the default PCU
compass mode. The “GYRO FREE” mode is only for the alternative method for the
unavoidable conditions.
MANUAL
In the event that a gyro compass is not available, the user must select the ‘’MANUAL’
mode and must manually input the heading value. (Refer to ‘6.1.2 Ship Heading’ for
inputting the heading value.) The PCU uses the heading angle when the PCU is receiving
the STR ID command from the ACU or when the antenna is searching for the satellite after
initializing of the antenna. Also, the PCU uses the heading angle when the antenna starts
another search for the satellite after search failure.
6.2.9 Automatic Beam Switching Protocol
The ACU can change the target satellite upon receiving the modem protocol (iDirect
OpenAMIP, Comtech EF Data ROAM and STM VACP) or the KNS protocol (GTP) from the
external device. This function is the ‘Automatic Beam Switching (ABS)’. The ACU receives
the ABS protocol via the Ethernet port.

External Lock TTL Level
When the searching reference is ‘External Lock Bit’, the ACU receives the lock signal via
the RJ45 console port from the satellite modem. If this lock signal is DC voltage, the ACU
considers 2.6~5VDC as logical high and anything less than 2.6VDC as logical low. The lock
69
signal varies according to the manufacturer. Logical high is the lock signal in the HNS
modem, whereas iDirect and Comtech EF data modem’s lock is logical low. Please refer to
the modem manual.

It is important that the operator recognizes symptoms correctly and searches for broken
parts, as KNS or the installer will then be able to cope with a problem more rapidly.
This section concerns symptoms indicating breakage and offers a list of points for
checking for those symptoms. There may be many checkpoints for one symptom, so you
must follow the checkpoint steps. If your problem is solved in the 1st step, there is no need
to follow the subsequent steps: Otherwise, you will have to go to the next step.
Symptom #1
ACU does not turn on following ACU power on.
1. Make sure that the AC power cabling is connected between the ACU
and the AC connector.
Check Point
2. Check the output power (48VDC) of the RX power supply.
3. Check the power line of the ACU board.
Symptom #2
The ACU display blinks continuously when the ACU power is on, and the
relay switch clicks repeatedly.
1. Remove the cable between the RX power supply and the ACU board.
Then, check the output voltage of the RX power supply.
Check Point
2. If the 1st step is OK, re-connect the cable. Check the short-circuit of
power line on the ACU board.
Symptom #3
ACU repeatedly displays ‘ACU INITIALIZE’, and relay switch clicks
repeatedly.
1. Disconnect the RX cable on the back panel of the ACU, then re-try the
power on.
2. If it is ok in the 1st step, re-connect the RX cable.
Check Point
3. Check the rotary joint: Disconnect the RX cable (CH1) on the top side
of the rotary joint, and then re-input the power to the ACU. If the symptom
is resolved, the rotary joint has a problem. Please replace the rotary joint.
4. If the problem is not resolved, re-connect the power cable of the PCU.
And remove the cable between the PCU motor driver. Re-input the power
to the ACU.
102
5. If the problem is not resolved, re-connect the cable between the PCU
and the motor driver.
Symptom #4
ACU cannot search the PCU.
(ACU ERROR: 0X 02 00)
1. Make sure that the Cable between the ACU and the Antenna is
properly connected.
2. Check the state of the PCU power supply.
Check Point
3. If the PCU is off, check that the RX L-band cabling between the ACU
and PCU is properly connected.
4. If the PCU is on, replace the PCU FSK module/ACU FSK module.
The sensor cage keeps hitting the limit switch.
Symptom #5
(In normal: The sensor cage rotates counterclockwise until it hits the limit
switch, whereupon it rotates in a clockwise direction.)
1. Make sure that the cable between the sensor board and the MCU
board is properly connected. Replace the cable.
Check Point
2. If the problem is not resolved, check the sensor board. Replace the
sensor board.
3. If the cable and sensor board do not have a problem, check the sensor
connector of the MCU board.
Symptom #6
The sensor cage directly rotates clockwise before hitting the limit switch.
1. Make sure that the cable between the sensor board and the MCU is
properly connected. Replace the cable.
Check Point
2. If the problem is not resolved, check the sensor board. Replace the
sensor board.
3. If the cable and sensor board do not have a problem, check the sensor
connector of the MCU.
Symptom #7
Operation of the sensor cage is OK, but the elevation or cross axis is not
working.
(In normal: Elevation and cross axis are moving to level off the sensor
103
cage after operation of the sensor cage.)
1. Check the motor driver. Replace the motor driver
Check Point
2. If the antenna still has a problem, please replace the elevation motor
or cross motor.
3. If the problem is not resolved, you must check the cable between the
motor driver and the PCU.
Symptom #8
The azimuth axis does not move after the sensor cage stays parallel to
the ground.
(The azimuth axis normally moves once the cage is parallel and stable.)
1. Check the motor driver. Change the motor driver.
Check Point
2. If the problem is not resolved, change the azimuth motor.
3. If the problem is not resolved, you must check the cable between the
motor driver and the PCU.
Symptom #9
All axes of the antenna are not working after initializing. The antenna has
a ‘PCU error 0X 40 00 00 00’.
1. Check the proximity sensor. Replace the proximity sensor.
Check Point
2. If the problem is not yet resolved, check the PCU.
Symptom #10
Heading angle does not synchronize to the ship’s gyro.
1. Check the ship’s gyro signal. Is the gyro signal level within the proper
range? Refer to ‘3.6.2.1 ACU Gyro Compass Cable Connection’.
2. Check the cable connection between the AUC and the ship’s gyro.
Check Point
3. Check the matching of the gyro compass type and the direction, etc. of
the ACU and the ship’s gyro
4. Check the NMEA converter. Replace the NMEA converter.
Symptom #11
Searching fail error message (PCU error 0X 00 10 00 00) occurs
immediately after initializing.
Check Point
1. Check the longitude of the target satellite. If the calculated elevation
104
angle and azimuth angle are out of its range, the ACU will be displaying
the searching fail error message (PCU error 0X 10 00 00).
2. Check the state of the GPS. Are the GPS data correct?
Symptom #12
The antenna is searching continually without tracking.
1. Check the ‘S&T Reference Details’ (Key ‘5’).
2. Is the antenna blocked?
Check Point
3. Check the skew angle. Is the skew mode on ‘AUTO’?
4. Please confirm that the RX frequency of the target satellite is within the
input frequency range of the LNB.
Symptom #13
The antenna is tracking the satellite, but cannot hold the tracking.
1. Is the antenna blocked?
Check Point
2. Check the LNB. Replace the LNB.
3. If the problem is not resolved, please check the PCU.
Symptom #14
The GPS LED is off.
1. Check the GPS antenna. Replace the GPS antenna.
Check Point
2. Check the cable connection between the PCU and the GPS antenna.
Symptom #15
The GPS LED blinks continuously after about 20 minutes.
1. Check the GPS antenna. Replace the GPS antenna.
Check Point
2. Check the cable connection between the PCU and the GPS antenna.
Symptom #16
Check Point
The antenna is tracking, but the modem is not locked.
1. Please confirm that the target satellite of the ACU and the target
satellite of the modem are the same.
2. Check the state of the GPS data. Is the GPS LED on?
105
3. Check the cable connection between the ACU and the modem,
console, and RX.
4. In the case of the TDMA modem, check the GPS data on the modem.
Symptom #17
RX is locked but the link is not locked on the modem.
1. Check the TX voltage on the ACU or modem. Is the TX voltage of the
ACU or modem within the input voltage range of the BUC?
Check Point
2. Check the TX frequency of the modem.
3. Check the cable connection between the BUC and the TX port on the
modem or ACU.
Symptom #18
The antenna is tracking, but the AGC or C/N level is lower than the
normal state.
1. Check the weather: Deep fog and cloud, heavy rain, etc.
Check Point
2. Check for blockage of the antenna.
3. Confirm what the antenna is tracking the side lobe. Then re-try the
search for the satellite using the ‘▲’ button.
Symptom #19
The antenna cannot save the changed parameters.
