Custom Cabling for Polycom HDX Microphone Arrays

You can create a custom-length cable that connects a Polycom HDX system to a Polycom HDX microphone
array or SoundStation IP 7000 phone. Start with the microphone cable (part number 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 array or SoundStation IP
7000 phone can vary between 18 in and 100 ft. The maximum length between subsequent microphone
arrays is 25 ft.
The following diagram shows an example of longer custom cabling from a Polycom HDX system to a
Polycom microphone array or a Polycom SoundStation IP 7000 Phone.
.The following steps explain how to wire this custom cable configuration.
CAT5 Shielded Cable
1 Identify the P1 connector on the Polycom HDX microphone cable according to the location of the
brown heat-shrink tubing as shown on
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.
2 If you are not sure which connector you need to cut off, use the following tables to perform a
continuity check between the connector and the cable colors. If you cut off P1, skip to step 4. If you
cut off P2, continue with step 3.
