INTRODUCTION
1.1
GENERAL
The ADL-256, I/0 Test Panel (N451515-0201) tests the operation of the Auto-Add
Data Link (ADL-256) Data Transmission System. The panel is used in
conjunction with an ADL-256 System known to be in operating condition. The
ADL-256 in turn, is used for troubleshooting purposes. Troubleshooting is
basically accomplished by comparing the input and output data of the system.
The Test Panel interfaces the transmitter and receiver units of the ADL-256
through three cable assemblies. Sixteen control-input switches located on the
I/0 Test Panel provide test data to the ADL-256 transmitter. The output data
is displayed on the I/0 Test Panel by means of LED's. Additional switches are
also featured on the test panel as follows:
1.
2.
3.
4.
An alarm indication display
Lamp Test switch.
Carrier Line Attenuation switch.
Relay/Transistor PCB select switch.
The Test Panel is powered by a 5 VDC, regulated supply which is mounted behind
the Test Panel. Over-current protection is provided by a 2A fuse.
1.2
PRINCIPLES OF OPERATION
The ADL-256, I/0 Test Panel (N451515-0201) provides 16 bits of input data to
the Opto-Interface PCB (N085722-1001) of the ADL-256 transmitter unit through
cable P3. When a control input switch (switches O through 15) is placed in
the Logic 1 position, a 5 VDC signal (from the Test Panel) is applied to the
corresponding indication input (0 through 15) of the Opto-Interface PCB.
The transmitter unit
indication inputs as
it is interpreted as
described in Service
recognizes any 5 VDC signal from the Test Panel to its
a Logical 1. If no signal is applied to the inputs, then
a Logical O. Data processing by the ADL-256 system is
Manual 6058.
The Test Panel may interface one of two PCB's at the receiver unit of the
ADL-256 system.
1.
Transistor Interface PCB (N085724-1001) with cable P1.
2.
Relay Interface PCB (N085725-1001) with cable P2.
The control and output indication signals for the output interface PCB are
monitored on the Test Panel with an LED display.

UNION SWITCH & SIGNAL
1.2.1
Transistor Interfacing PCB
Output indication signals of a Transistor Interface PCB will be monitored when
5 VDC is applied, by means of the Test Panel, between the collector and
emitter of the output transistors located on the PCB. The LED's on the Test
Panel are connected in series with the collectors of the transistors. For
each output transistor that is switched ON, current flows through a
corresponding LED on the Test Panel causing it to light. The LED's in the
front row of the Test Panel indicate that the output transistors of the
Transistor Interface PCB are switched ON or OFF.
1.2.2
Relay Interface PCB
Control output signals of a Relay Interface PCB will be monitored when 5 VDC
is applied, by means of the Test Panel, betwen the heel and contacts of the
output control relays. The LED's on the Test Panel are connected in series
with the front and back relay contacts~ A FRONT or BACK LED will light for
each control output signal depending on whether the front or back relay
contacts are closed.
1.2.3
Test Panel Switches and Indicators
The Relay/Transistor PCB select switch switches the test panel power supply
common between cables P1 and P2. This prevents a false indication at the Test
Panel should both cables be connected to output interface PCB's at the ADL-256
receiver unit. The Relay/Transistor PCB select switch is placed into the
position corresponding to the output PCB under test.
An alarm indication on the Test Panel is used to check the alarm circuit relay
on the Receiver Housekeeping PCB (N085723-10). The Alarm LED on the Test
Panel should light whenever the Alarm LED on the Receiver Housekeeping PCB is
lit or when no power is applied to the ADL-256 receiver unit.
A Carrier Line Attenuation switch is provided to allow a -26 DBM, H-pad to be
inserted in series with the ADL-256 carrier system. The H-pad is switched in
to attenuate the carrier signal which allows testing of ADL-256 system
sensitivity.
A Lamp Test pushbutton checks the operation of the Test Panel LED's. Each
panel LED contains a built-in diode, which when its cathode is tied to common
lights the LED. By depressing the Lamp Test pushbutton, the lamp test pins of
the LED's are tied to common causing all the Test Panel LED's to light.

TEST PANEL PROCEDURES
The ADL-256, I/0 Test Panel must be mounted in a code rack with the
ADL-256 transmitter and receiver units mounted directly above and below
the Test Panel. It is also recommended that the data sets for the
ADL-256 transmitter and receiver units be mounted in the same code rack.
The following procedure outlines I/0 Test Panel installation:
1.
Mount the ADL-256, I/0 Test Panel into a 19" code rack between the
ADL-256 transmitter and receiver units.
2.
Connect the 115 VAC power line to TB-D, pins 19, 20, and 17 (GND)
on the Test Panel.
3.
Connect the transmitting, data-set output to the carrier #1 inputs
on TB-D, pins 21 and 23 on the Test Panel.
4.
Connect the receiver, data-set inputs to the carrier #2 inputs on
TB-D, pins 22 and 24 on the Test Panel.
5.
Connect the alarm indication relay contacts from the receiver
housekeeping PCB (N085723-1001) at connector A pins 2 and 3 to
TB-D, pins 1 and 2 on the test panel.
6.
Install a steel retaining bar (N308947-001) or equivalent across
the back of the code rack, behind the Test Panel.
7.
Secure the three cable assemblies from the Test Panel to the
retaining bar in Step 6 to reduce cable tension.

OPERATIONAL CONNECTIONS
Connect the Test Panel, using the following procedure, to check the ADL-256
Data Transmission system.
1.
2.
3.
4.
3.2
Install connector P3 to side A of an Opto-Interface PCB located in
the ADL-256 transmitter unit.
Note the Opto-Interface PCB's position in the transmitter unit and
refer to the same position in the card enclosure at the receiver
unit. Check the output interface at this position for a relay or
transistor PCB.
If a Relay Interface PCB is present, install connector P2 to side
A of the PCB. Place the Relay/Transistor interface select switch
in the test Relay PCB position.
If a Transistor Interface PCB is present, install connector P1 to
side A of the PCB. Place the Relay/Transistor interface select
switch in the test Transistor PCB position.
OPERATIONAL PROCEDURES
To operate the ADL-256, I/0 Test Panel, use the following procedures:
1.
2.
3.
NOTE:
Connect the Test Panel as described in Section 3.1.
Place the Carrier Line Attenuation switch in the OUT position and
energize the Power switch. The Power LED on the Test Panel should
be lit.
Correct operation of the ADl-256 Data Transmission system is
indicated when every Logic 1 control input signal to the
transmitter unit (Opto-Interface PCB) generates an output at the
receiver unit (output interface) and activates a corresponding LED
on the front row of the Test Panel (i.e., control bit O when input
as a Logic 1 causes LEDO to light on the front row of the Test
Panel).
When monitoring outputs from a Relay Interface PCB, either a front or
back LED is lit for each indication bit. When monitoring outputs from
a Transistor Interface PCB, only the front LED's are lit for each
control bit which is input as a Logic 1.
4.
6132, p. 4
If all control, input-bit switches are placed in the Logic 1
position, all front row LED's should light. If all the control,
input-bit switches are placed in the Logic O position, all back
row LED's should light for a Relay Interface PCB. Both front and
back row LED's should be off for a Transistor Interface PCB with
the control, input-bit switches in the Logic O position. Try all
control, input-bit switches separately to ensure that no two
signals are tied together.

7.
Place the Carrier Line Attenuation switch to the IN position and
.repeat Steps 3 and 4. The ADL-256 operation remains unchanged.
To check all input and output indications, repeat Steps 1 through
5 for each Opto-Interface PCB in the transmitter unit with its
corresponding output PCB in the receiver unit.
If the Alarm LED on the Receiver Housekeeping PCB goes on, the
Alarm LED on the Test Panel should also light. To check its
operation, remove one of the output interface PCB's from the
receiver unit. A~er the receiver unit attempts to address the
removed PCB three times, the Alarm LED's on the Receiver
Housekeeping PCB and the Test Panel are lit.
If the Test Panel indicates that the ADL-256 DATA Transmission system is
faulty, troubleshoot the symptoms as detailed in Section II of Service Manual
6058.
