6......................................RX shield
2) Plug the modular cable connector into the RJ-45 jack.
3) Connect the coaxial cables to the TX Out and RX In
connectors. Congratulations, you have finished installing the
Model 460!
Installing the Model 460-TBP
Do the following:
1) Strip the outer jacket insulation from the twisted pairs about 1
inch.
2) Strip back the insulation on each of the wires about .25 inches.
3) Connect one pair of wires to the two XMT (transmit) positions
on the terminal block. The Model 460-TBP is not polarity
sensitive so either wire may connect to either pole.
