Connecting To An Rch Junction Box - Motorola MC3000 Operating And Installation Manual

Connecting to an RCH Junction Box

The deskset can be connected via an 8-wire CAT-5 cable (4 wires for audio and 4 wires
for data) to an RCH Junction Box (CDN1337, CDN6304, CDN6683) which is then con-
nected to the radio. Figure 2-10 shows how the cable must be constructed.
If you are using an RCH Junction Box, you will need to do the following:
1. In the Configuration and Test program:
• set option 9 "Busy Polarity" to High
• set option 12 "RX Impedance and Circuit" to Differential
2. Ensure the wiring of the cable is exactly as per Figure 2-10.
3. Connect the cable from the RCH Junction Box (Host port) to the 8-pin RJ45 connector
labeled "Audio/Data" on the back left hand side of the MC3000 deskset.
