Connecting the Control Unit to the Network Interface
RJ11 and RJ14 Network Interface Hardware
■ D2R cords
CAUTION:
Incorrect wiring can damage the ports and cause them to stop
functioning. Make sure you use the proper cords. For all GS/LS
modules, do the following:
— Use a D2R cable from an RJ11.
— Do not use the Brand-Rex Quad cable from an E66 block.
If you cannot avoid using the Brand-Rex Quad cable,
reverse the tip and ring leads at the E66 block to correct the
mismatch.
