WARNING
To prevent electrical shock, do not install equipment in a wet location or
during a lightning storm.
CAUTION
Electronic modules can be damaged by static electrical discharge. Before
handling modules, wear an antistatic discharge wrist strap to prevent damage
to electronic components. Place modules in antistatic packing material when
transporting or storing. When working on modules, always place them on an
approved antistatic mat that is electrically grounded.
1.2 Detailed Level Procedure 712
1. Measure and Pre-cut Wire
Determine and cut the length of wire necessary to reach from the RS-485
wire-wrap header, P2/P21, in the first shelf in the chain to the RS-485 wire-wrap
header, P2/P21, in the second shelf. Remember to allow for stripping the ends of
the wire, routing the wires out to the right side of the shelf to the frame, and tying
down in accordance with CO SOP.
2. Make Wire-wrap Connections to the Host Shelf
Using the wire-wrap tool, connect the shielded, twisted pair interconnect wire to
the RS-485 wire-wrap header, P2/P21, on the host Total Access 3000/3010
backplane. Connect the two conductors to the “OUT” A and B pins, and the shield
or drain wire to the “OUT” ground pin. See Figure 1 for wiring details.
3. Make Wire-wrap Connections to the Next Shelf
Run the interconnect wire to the backplane of the next in the chain, routing the
wire out to the right side of the frame. Using the wire-wrap tool, connect the two
conductors of the interconnect wiring to the RS-485 wire-wrap header, P2/P21, on
the backplane of the Client shelf. The two conductors will be wired to the A and B
“IN” pins, and the ground or shield wire should be at the end of the insulation.
Take care to connect the A pins of each shelf together, and the B pins together. Do
not cross the polarities. The drain wire should be connected at only one end to the
ground pin, but not both. See Figure 1.
