Custom Cabling for Polycom HDX Microphones
You can create a custom-length cable from the Polycom HDX 9000 Series
system to the Polycom HDX microphone. Start with the microphone cable
(2457-23216-001), and cut off the P1 end. Using the wiring tables shown, create
a custom cable from the microphone to a wall plate or other interfacing device.
Next, from the wall plate or other interfacing device, run shielded CAT5 or
better cable to the Polycom HDX system, terminating with a shielded RJ-45
plug connector.
The total length from the Polycom HDX system to the first Polycom
microphone can vary between 18 in and 100 ft. The maximum length between
subsequent microphones is 25 ft.
The following diagram shows an example of longer custom cabling from a
Polycom HDX system to a Polycom microphone or a Polycom SoundStation IP
7000 Phone.
.
The following steps explain how to wire this custom cable configuration.
1 Identify the P1 connector on the Polycom HDX microphone cable
according to the location of the brown heat-shrink tubing as shown on
page Polycom HDX Microphone Array Cable on page 2-43 . 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.
