Figure 10 RXT-320 Wireless Transceiver Remote Mounting
A custom extension cable needs to be built per Figure 11 to interface the remote transceiver to the Model 100
Terminal Board.
The recommended cable for remote transceiver separation is Belden 1421A (24AWG
shielded twisted pair, 4 pairs w/drain wire).
NOTE: It is highly recommended to install the extension cable inside rigid metal conduit to
eliminate potential EMI and RFI interference and to maintain a Class I Division I rating.
NOTE: Color coding of the cable will no longer match the color coding on the Model 100
Terminal Board for the J1 connector.
NOTE: Programming of RXT transceiver from the Model 100 Terminal Board will be
disabled.
