2-Series RS-232/422/485
Expansion Cards: C2COM-2/3
Introduction
Functions and Features
The C2COM-2 and C2COM-3 RS-232/422/485 expansion cards provide RS-232,
RS-422, or RS-485 serial communication for a Crestron
®
2-Series control system
(PRO2, RACK2, PAC2, or AV2 with cage card). The C2COM-2 has two serial ports
while the C2COM-3 has three serial ports. The C2COM-2/3 fits in any of the 2-
Series control system’s Y-bus slots. The Y-bus provides high-speed communications
and supports current and enhanced Crestron control system expansion cards. All
C2COM-2/3 ports can communicate with the Crestron Network Poll Accelerator.
NOTE
: The Network Poll Accelerator allows a 2-Series control system to maintain a
fast response time (high-speed communication) between the control system and a
large number of Cresnet
®
devices. For more information, refer to the latest revision
of the Network Poll Accelerator Operations Guide (Doc. 6087).
The C2COM-2/3 supports baud rates up to 115,200 bps (and higher with the
Network Poll Accelerator), and a variety of communication parameters with
hardware and software handshaking. Valid parameters are shown in the functional
summary.

NOTE:
Due to a non-standard pin configuration that allows the C2COM-2/3 to
support RS-232, RS-422, and RS-485, Data Set Ready (DSR) and Data Terminal
Ready (DTR) are not supported.
