Polycom RealPresence Group Series Serial Cable
This cable connects a Polycom RealPresence Group Series system to a serial device. It is 8-pin mini-DIN
to DB-9.
Notes:
• The 8-pin mini-DIN RS232 connection is wired per Polycom RS-232 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.
