Data Hiway Testing

The following test procedure tests the Channel A and Channel B Data
Hiway cable connections. These test procedures insures that the signal
lines are correctly installed.
Referenced testing points are CH A and CH B (+) and negative (-) and
shield ground termination's.
The following test equipment is required to test continuity of installed
Data Hiway Channel A and Channel B signal lines:
9 Vdc battery, with connector leads and clips
Digital Volt Ohm Meter (DVM) or equivalent
10K ohm resistor, with leads and clips
Data Hiway channel A and channel B + and - signal line continuity can
be checked by performing the following procedures. Devices can be op-
erating on the Data Hiway when making continuity checks. Perform the
check for each device connected to the Data Hiway.
Do not skip testing any devices connected to the Data Hiway. Check at
the incoming termination's on the I/O chassis, the Termination Boards in
the Analyzer Electronics enclosures, LINC units, and any other Data
Hiway devices. Typical problems are reverse polarity; poor contacts on
wiring terminals, opens, and shorts and cross channel wiring. Every point
in the Data Hiway wiring should be carefully checked to ensure correct
wiring.
Step
1. Connect the positive lead of the 9-volt battery through the 10K
ohm resistor to Channel A (+) terminal and connect the negative
lead of the battery to the Channel A (-) terminal at any connec-
tion point on the Data Hiway.
2. Using DVM measure for 9.0 Vdc across Channel A (+) and
Channel A (-).
3. Repeat steps 1 and 2 for Channel B.
