Longer Microphone Cable or Extension

[Anonymous]

We currently have the 50ft microphone cable for our Group Seris microphone but unfortunately that is still a 10ft shy of our needs. Doing a search, there doesn't seem to be any other cable longer than 50ft or any sort of coupler/Male to Female extension cable. Does anyone know of a solution to extend the cable even more?

Hi @Midnite8,

Hi,
check the RPGS integrators guide:
https://support.polycom.com/content/dam/polycom-support/products/telepresence-and-video/group-series...

In the section "Custom Cabling for Polycom Microphone Arrays" you'll find all instructions and wiring diagrams.

You'll have to use SFTP cables for >25' lengths, and if you'll run them through the false ceiling please note that they have to be plenum rated.

Hello,

We have ran a RJ-45 cable that is ~60 ft and have two of the Walta to RJ-45 adapters. Do we follow the wiring diagram for "Shielded Conference Link Crossover Cable"? Or the wiring diagram under "Wire a custom cable"? 

If we follow the diagram for shielded conference link crossover cable, does P1 and P2 identify each side of the RJ45 cable?
