Crestron C2COM-2/3 2-Series RS-232/422/485 Expansion Cards
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
(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 2Series 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
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.
Functional Summary
• Supports RS-232, RS-422, and RS-485 communications via DB9 male
connector
• Baud rates: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600 and
115200
• Parity may be even, odd, none, or zero stick (parity bit always 0)
• Data bits may be 7 or 8
• Stop bits may be 1 or 2
• Both XON/XOFF software handshaking and RTS/CTS hardware handshaking
are supported
• Break sequence can be generated under program control

2-Series control system
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.

Physical Description
The C2COM-2/3 is a circuit board fastened to an aluminum faceplate. The card is
manufactured to easily fit in an unoccupied Y-bus slot of a Crestron 2-Series control
system. The faceplate on the C2COM-2 contains two identical bidirectional DB9
male connectors while the C2COM-3 contains three bidirectional DB9 male
connectors. The connectors are labeled A, B and C. Refer to the following
illustrations for a detailed view.
