Integrator's Reference Manual for Polycom HDX Systems
Polycom, Inc.
When connecting two Polycom HDX microphone array host devices, a crossover
cable is required. To build a custom crossover cable for this purpose, you should
use shielded CAT5 or better cable. Each end of the onle should have a shielded
RJ-45 plug connector that connects to a Polycom HDX microphone array host
device. The maximum supported cable length is 100 feet.
Due to differing use of the twisted pairs within the cable, the pinout for this custom
CAT5 crossover cable is not the same as the pinout that is used for standard
Ethernet cables. Do not use standard Ethernet cables. Instead, for best cable
performance, refer to the following pinout information to create this custom CAT5
crossover cable.
Drawings and part numbers are provided for reference only. Polycom claims no
responsibility or liability for the quality, performance, or reliability of cables based on
these reference drawings, other than cables provided by Polycom. Contact your
Polycom distributor or Polycom Custom/Vertical Products to order cables that meet
the appropriate manufacturing tolerances, quality, and performance parameters for
your application.
