Integrator’s Reference Manual for the Polycom RealPresence Group Series

Polycom, Inc.

This cable connects a Polycom RealPresence Group system to a serial device. 
It is 8-pin mini-DIN to DB-9.

• The 8-pin mini-DIN RS232 connection is wired per Polycom RS232 and does 

not follow VISCA pinout convention.  Do NOT try to use a cable meant to 

support VISCA in this application as it will not work correctly.

• Do not use this adapter DIRECTLY CONNECTED to multi-purpose AMX serial 

ports. AMX systems support both RS-232 and RS-422. Therefore, for the most 

reliable RS-232 support with this adapter, use an additional null modem 

cross-over cable in-line that only carries only pins 2, 3, and 5, with pins 2 and 

3 crossed.
