Notes:

• If your ceiling is 10 feet (3.05 m) or higher,

you should order an optional 6-foot (1.82 m)

drop cable (part number 2215-09591-002 for

black or 2215-09591-001 for white) for each

Ceiling Microphone Array.

• If you are creating your own cables, refer to

the Integrator’s Reference Manual for Polycom

HDX Systems for cable pin-outs. You can ﬁnd

this document at

www.polycom.com/videodocumentation.

NOTE: Verify that the number of pins on the cable

connector matches the number of pins on the

connector on the electronics enclosure.

If you do not have a suspended ceiling in your

room, continue with Step 8 on page 15.
