Cabling, Wiring, and Assembly
Step 1:
Connect the cable assembly's P184 connector to the ARM shelf back-
plane connector J184.
Step 2:
The prepared end of the cable assembly shall be wire wrapped to the
TS1 terminal block in accordance with Figure 3-20a.
NOTE:
There are two black wires to be connected to the TS1 block
(terminals 7 and 24). The black wire to terminal 7 is the
grounded shield from the two shielded pairs of P184. The
black wire to terminal 24 is from P1A.
Step 3:
Add an additional black wire from terminal 7 to the ground lug terminal
on the left mounting screw.
NOTE:
Clock termination resistors and wiring connections to the TS1
block from the CO Clock and the CO Alarms will be made in
subsequent operations. Refer to those sections for details.
