APPENDIX D: Cable Replacement Procedure
Install new tie wrap centered on grommet sleeve as shown in Figure
D-3. When the tie wrap is finally tightened, its ratchet box should be
approximately in the plane of the wire fan.
5. Tighten tie wrap as much as possible (until wrap material begins to
stretch). Cut off excess tie wrap.
6. Carefully guide the grommet and circuit board into the case. Once the
cylindrical neck on the grommet is through the hole, use the neck to
pull the grommet into place. The twisted pairs will bunch up when
properly installed. If necessary change their positions to avoid
pinching.
NOTE
If using ScTP, the drain wire must not short against the circuit shield nor
the case (if case is copper painted). Shorten the drain wire by cutting as
required to accomplish clearance.
7. Reinstall the 4-40 screws from the open side of the case. Make sure the
screws extend through the circuit board and into the plastic of the case.
8. Reinstall the Performance Module in the SCAN-LAN Vt body by
alternately turning each knurled thumbscrew a small amount or
turning them simultaneously. Only tighten these screws finger-tight.
9. Connect the remote and run the WIREMAP test using the CAT 5 Basic
Link Cable standard to make sure the new cable was installed correctly.
(If the 12/36 pairs are crossed you probably wired up a 568B cable as a
568A or vice versa. Swap the Orange and Green pairs. See Table D-1.)
