4.2. CSC-196 Configuration scheme
4.2.1. General description of the configuration scheme
A CSC-196 device can form many time synchronization system freely by configuring various
signal receiving cards, such as the basic, master-slave mode and run-standby mode. The section
will introduce typical configuration schemes.
In the section, interconnection of master and slave clocks adopts optical fiber. Because optical
fiber connection has advantages of anti-interference, long distance transmission, and stable
transmission delay, so interconnection of master and slave clocks interconnection with
optical fiber is recommended.
The CSC-196 master-slave clocks interconnection adopts IRIG-B signals, so only one optical port
or electric port is used for input and output signal of each channel.
Difference between the basic and the master-slave mode time synchronization system locates
whether the master clock connects the slave clock or not. The configuration scheme are similar.
Limited by the length of the document, only configuration of the master-slave mode system is
introduced here, while it becomes a basic time synchronization system if the slave clock is
removed.
4.2.2. Software configuration of the input channel
For normal operation of the clock, software configuration of the input channel must correspond to
hardware configuration of the signal receiving card, software configuration of the CSC-196 input
channel can be modified by the configuring serial port, the configuring parameters are saved in the
FLASH of the device, power-down is not lost (refer to Appendix A for configuration
modification).
Configuring format of the input channel is “1XX2XX”，“1” refers to the signal receiving card,
“2” refers to the sub-signal receiving card.
“X” is for input configuration, there are four kinds:
1） N: No input signal.
2） A: Wireless time reference signal, usually from GPS or BD OEM board.
3） B: From input signals of the master clock, viz. local wired time reference signal, all
27
CSC-196 Time synchronization device for power system
Manual
IRIG-B time comparing code.
4） C: Input signals from the time synchronization network, viz. remote wired time reference
signal, all are IRIG-B time comparing code.
Detailed input signal type (such as BD OEM board, GPS OEM board, IRG-B) and input signal
polarity in input channel configuration information, CSC-196 can identify type and polarity of
input signals automatically and make relative treatment.
If there is no sub-signal receiving card in the casing, the configuration format should be
“1XX2NN”.
If a signal receiving card supports only one channel of input (such as G4, G2 and J1, etc. ), change
the second “X” to “N” corresponding to this card, viz. “1XN2XN”.
If configuration information contains A, it refers to the master clock, the others are slave clocks;
working logics of the master and the slave clock are different, refer to Appendix F for details. An
obvious difference in application between the master and the slave clock locates: when all external
input time reference signals of a system are abnormal, the master clock can keep punctual
automatically, but all slave clocks follow output of a master clock, by this way, coherence of
outputs from multi clocks in the station in punctual state.
The clock output and has highest priority, and keep synchronization with the normal input
source.
Priority of input signals: A type input > B type input > C type input
In same kind inputs, the signal with hardware interface listing ahead has higher
priority.
When the jumper J15 of the main signal receiving card is open, the device will enable default
configuration “1AN2NN”, viz. the device connects only one channel of input time reference
signal, here input channel configuration information in the FLASH is invalid.

4.2.8. Connecting to time synchronization network
CSC-196 can support to connect the time synchronization network, the signal interfaces are all for
35
CSC-196 Time synchronization device for power system
Manual
IRIG-B (DC) time comparing code, within the above mentioned configuration schemes, the
optical fiber input interface remained in the signal receiving card can be used to receive wired
time reference signal (time accuracy must reaches ±1us) from the time synchronization network,
during input channel configuration, configure the relative input channel to “C”.
4.2.9. Connecting method of client-side equipments
According to Appendix F, in the run-standby time-transfer system, if the GPS/BD in a master
clock is faulty, it will synchronize IRIG-B (DC) from the other master clock automatically, here
time quality of IRIG-B time comparing code output from this master clock will be marked as
abnormal synchronization (the CSC-196 mark is 3, refer to special running state of the master
clock), the second punctual edges of all output time signals can keep ±1us precision yet, and
synchronization state in the output serial port message is normal too.
Typically the PMU device connects IRIG-B(DC) time comparing signals, and judge the time
quality marks in B code strictly. So the PMU should connect the slave clock when transferring
time to the PMU from the run-standby time-transfer system formed by CSC-196. For other
devices such as protection, measuring and control, and oscillograph, just connect any clock in the
time comparing system.

Manual
and
5.1. Requirement for antenna installation
5.1.1. GPS antenna installation requirement
The GPS antenna should locate the top of a building or other open area, and the top of the antenna
should keep horizontal. Install the antenna on the boom, and fix the boom on the top of a building
with expansion bolts. The turning radius of an antenna should not be too small during construction,
length of antenna cable is designed according antenna gain strictly, so never cut, expand,
shorten or add any connector, or receiving effect will be impacted
severely, even no signal .
The separated type antenna connects cable with the connector behind the mushroom head, when
using the separated type antenna, please confirm matching between the gain of the antenna
mushroom head (marking on the mushroom head typically) and cable, for wrong matching will
cause bad satellite locking. The antenna connectors outdoors should be packed with water proof
insulating tape to avoid aging.
Location of the GPS antenna may impact satellite locking directly, please choose the optical
position at site for the antenna to guarantee its normal operation.
The principle for erecting the GPS antenna is looking up along with the antenna head, a 360 o sky
is seen. Refer to the correct and incorrect installation diagrams hereinafter. Since it is hard to erect
the antenna at the central control room of the power plant, for the sake of satellite locking quality,
the master clock to connect the antenna should be arranged at the network control room or the
switching station with open space around, and expanding the slave clocks at the CCR through
optical cable.

5.1.2. Requirement for BD antenna installation
There should be no obvious barrier within 50m southerly, the other installing requirements are
same with the GPS antenna.
5.2. Routine initialization
After field installation of the CSC-196, start initialization as following:
1.
Connect the GPS antenna, BD antenna, optical fiber, cable and so on with relative
terminals of the device.
2.
Power on the device, observe display on the front panel within several seconds after
power on according to Appendix B, or check the input channel configuration of the
device by the order $c, refer to the usual configuration schemes in Section 4.2 of this
instruction, make sure matching of the input channel configuration of the device and the
clock connecting mode.
3.
Check output jumper setting of pulse output card P at site, if hour pulse 1PPH is
required at site, use the configuration order $p to set the PPM output port as hour pulse
1PPH output.
4.
Check jumper setting, output message type, baud rate, time interval and so on of
message output card T according to field requirements, if the requirements are not met,
modify jumper on the message output card, choose RPS or RPM message output, or
modify the output message parameters of the RPS or the RPM port with the
configuration order $r.
5.
If long optical cable connection between the master and the slave clock are used, actual
time propagation delay of optical cable should be calculated based on 5.5us/km delay
for optical cable, if time propagation delay of optical cable exceeds requirement of time
comparing precision to the time transferred equipments, make time compensation to
input and output signals of the device with the order $d.
38
CSC-196 Time synchronization device for power system
Manual
Perform time compensation to the signal at the input signal side usually, for example,
clock A, B and C are connected as the following figure, TPD of 1km optical cable is
5.5us, for 2km is 11us, so set TPD compensation parameter at Clock C, 5.5us for input 1,
and 11us for input 2. (the parameter for TPD compensation is positive, typically no lead
compensation at site of the engineering)

5.3. Initialization of BD signal receiving card
Initialize the device with the BD signal receiving card JF4 at site in case of the first power on as
following:
1.
For a BD time-transfer solution, there must be the GPS signal receiving cards in the
same CSC-196 or another CSC-196 at the same place, so connect it with the GPS
antenna and power on, wait for the CSC-196 to lock the satellite normally and start to
output time comparing signals.
2.
Connect the CSC-196 with the GPS receiving card with the configuration serial port
wire and check the order $q; with OEM board, observe location information in returned
message carefully, wait for stabilization of basic information such as longitude, latitude,
altitude and so on, and then record the altitude.
3.
Connect the BD signal receiving card CSC-196 with serial port wire, and send the BD
OEM board configuration order $oBD H=xxxxx.x;, where xxxxx.x is the local altitude
obtained from the GPS OEM board (No zerofill for high order position).
4.
After a while, the BD OEM board should lock the satellite normally, here the “Time
quality” nixie tube on the front panel should display 0, and the relative indicators of
“Main input” and “Standby input” should light constantly.
5.
Check the order $q; with the OEM board, observe the BD OEM board locating
information, longitude, latitude and altitude in the returned message and locating
information from the GPS OEM board, which should be basically equivalent.
6.
If operating condition of the BD OEM board are not normal all along, use the OEM
39

A.1 Connection of configuration serial port
The configuration serial port can realize checking and setting of parameters and operating mode of the
device. Connect the computer serial port and the CSC-196 configuration serial port with the special serial
port wire, set the serial port parameters of the computer: 8 digits of data bit, 1 stop bit, no verification, baud
rate 9600, ASCII code sending and display. Input according to specification described in this appendix for
receiving the reply message from CSC-196.
Either the super-terminal of Windows or other serial port debugging software is available.
Example for WINDOWS super terminal:
（1） Program－>accessories－>communication－>super terminal－>input any name－>confirm
－> set “using when connection” to the serial port connecting CSC-196－>confirm.
（2） Operating in the pop-up box: modify “digit per second” to 9600 -> modify “data stream
control” to “Xon/Xoff” -> confirm.
（3） Operating in the pop-up box: file－>property－>set－>ASCII set－>select “local return
display input character”－> confirm－>“function key, arrow key and Ctrl key for” select
“windows key”－>confirm.
（4） Input the order for sending in the window, after input “;” at the end of the order, the order will
be sent to CSC-196 automatically; the returned serial port message from CSC-196 will be
displayed on the terminal window.
（5） When using the super terminal, the order should be input once, any movement of the cursor,
delete and back space are regarded as special characters to CSC-196; so once an command
character is wrongly input, input “;” to end the wrong order, and press Enter to change
another line, and input the order again.

Fault handling method
1. Fault channel corresponding to OEM board card J1/JF1/JF4: Power the device
again, if the fault existing yet, the signal receiving card may have hardware fault.
2. Fault channel is IRIG-B input: Check the indicator corresponding to this input on the
signal receiving card for flashing; if not flashing, check external signal connection; if
flashing normally, power on again, if the fault exits yet, the signal receiving card may
have hardware fault.
1. Input signal is from GPS or BD OEM board: Check location and connection of the
antenna, OEM board satellite locking abnormity may cause this symptom.
2. The input signal is IRIG-B output from outsourcing time-transfer device: Confirm
if the second punctual edge of the outsourcing time-transfer device output IRIG-B can
meet 1us precision requirement or not, check optical fiber and cable connection, check
hardware of the output and the input interface.
3. Input signal is IRIG-B from the other CSC-196: Check connection of optical fiber
and cable, check hardware of the output and the input interface.
Power on the device again, if the fault existing yet, the signal receiving card may have
hardware fault.
1. Input signal is OEM board: refer to troubleshooting of ERR STATbit0.
2. Input signal is IRIG-B: usually input signal interruption or CODE B FORMAT error,
check ERR STATbit0 setting, check WORNG STATbit0 setting.
1. Input signal is OEM board: check location and connection of the antenna, confirm
actual operating state of the OEM board by the front panel, or observe actual satellite
locking quantity and satellite state of the OEM board with $q.
2. Input signal is IRIG-B: Check satellite locking of the clock device providing IRIG-B
output.
1. Hardware problem: When plug in input time comparing optical fiber and setting, it is
normal, or check optical fiber connection, output optical port and input optical port.
2. Software configuration problem: Check input channel configuration and input signal
connection, for example, configure J1 card wrongly as 1AA2NN.

supporting the card J1/JF1
GPS OEM board connection antenna open circuit,
only support the card J1/JF1
Current input time signal and output time signal
are not synchronization (error more than 1.5us)
1. When the device is resuming the track locking state from long term punctual keeping
state, this fault may appear, it can resume automatically in short term. Except for this,
abnormity, make follow-up check.
2. Check input, output time compensation setting of each clock, make sure if wrong
compensation is set.
3. The clock has BD OEM board: Check location coordinate of BD with $q according
to the one obtained from GPS, If not, BD location coordinate error, use $o reinitialize
altitude of BD, precondition of $o is three BD satellites must be locked, so location of
the BD antenna must be guaranteed.
4. Input signal is IRIG-B: If IRIG-B is from the clock device of other manufacturers,
make sure operating condition of the clock is normal or not.
Refer to Section 4.2 of the instruction, check configuration of the input channel,
connection of input signal.
Check connection of the GPS antenna, if antenna short circuit still exists when the antenna
is disconnected, the signal receiving card may have hardware fault.
Check connection of GPS antenna, cut the antenna connector and re-weld at site cannot
guarantee reliability of antenna connection
Refer to troubleshooting of ERR STATbit6 and WORK STAT bit2.
Make sure general faulty point of input signal according to state display information of the
front panel.
Bit1=0
1. Input signal is OEM board: check location and connection of GPS/BD antenna.
2. Input signal is IRIG-B: Check satellite locking of the clock providing IRIG-B output.
1. Input signal is OEM board: the OEM board may appear this symptom in case of
satellite losing locking or unstable satellite locking, if the device is not normal after
Unstable current input pulse cycle
power on for long time, check the GPS/BD antenna.
Bit2=0
2. Input signal is IRIG-B: Check hardware connection of IRIG-B signal, if signals from
the clock of other manufacturers, check its operating condition.
Note: digits of WORK STAT correspond to current operating condition of the device, refreshing per second in real time, short time abnormity may appear
when the clock works normally.
Reason: IRIG-B odd and even verification error (element 75 should be odd, refer to
Appendix E), position identification mark P locates wrong position, and time information
Bit0=1
IRIG-B verification error
exceeds allowable limit.
1. If the IRIG-B signal comes from the clock of other manufacturer, confirm if the

2. Check hardware connection of input IRIG-B signal.
3. Print the original element of input IRIG-B with $b, and find fault reason.
1. Input signal is OEM board: the OEM board may appear this symptom in case of
satellite losing locking or unstable satellite locking, check the GPS/BD antenna,
confirm actual operating condition of the OEM board with information of the front
panel, or observe actual satellite locking quantity of the OEM board with $q.
