Custom Cabling For Polycom Microphone Arrays - Polycom RealPresence Group Series Reference Manual

Custom Cabling for Polycom Microphone Arrays

You can create custom-length cables for connecting a RealPresence Group Series system to a Polycom
Microphone Array or SoundStation IP 7000 phone.
Start with the microphone cable (part number 2457-23216-002) and cut off the P1 end. Using the following
wiring tables, create a custom cable from the microphone to a wall plate or other interfacing device. From
there, run a shielded CAT5 or better cable to the RealPresence Group Series system, terminating with a
shielded RJ-45 plug connector.
The length from the RealPresence Group Series system to the first Polycom Microphone Array or
SoundStation IP 7000 phone can be between 18 in. and 100 ft. (a RealPresence Group Series 700 system
allows two such connections). Polycom recommends you use shielded CAT5e cables for lengths greater
than 25 ft.
The maximum length between subsequent microphone arrays is 25 ft.
Note: When creating custom cables, make sure what you're using meets local
building regulations.
The following diagram shows an example of longer custom cabling from a RealPresence Group Series
system to a Polycom Microphone Array or SoundStation IP 7000 Phone.
