Wire a Custom Cable
The following steps explain how to wire this custom cable configuration.
Note: Refer to
RealPresence Group System
RealPresence Microphone Array Cable to ensure the cable is connected correctly.
1 Identify the P1 connector on the Polycom RealPresence microphone cable according to the location
of the brown heat-shrink tubing as shown on the
Walta-Walta Cable. Remove the P1 connector and skip to step 4. Note that two separate vendors
manufacture these cables, which are electrically equivalent but have different color coding. If you
cannot identify the P1 connector, remove either connector from the cable and continue with step 2.
The following tables show the color coding for the cable wiring.
