Control Port Expansion Module
Installation Guide
Description
The C2N-IO is a very compact device that adds control
ports to any Crestron®2-Series or 3-Series®control
system. It connects via the Cresnet®control network
and provides one RS-232, one IR, and two relay control
ports.
Installation
The C2N-IO can be mounted inside a standard 2-gang
U.S. or U.K. electrical box using the included 3M®Dual
Lock®fastener or mounted to another suitable location
using the included mounting bracket.
To use the included mounting bracket, use the included
04-40 x 1/8” screws to attach the mounting bracket as
shown in the following illustration. The only tool
required is a #1 Phillips screwdriver.
NOTE: Screws to secure the C2N-IO to a surface are
not included.

Hardware Hookup
Make the necessary connections as shown in the

have been made.
CAUTION: Incorrect wiring may damage the C2N-IO.
NOTE: The RS-232 COM port is intended for use
with relatively simple devices that send and receive
small packets and do not generate a lot of data. A
small amount of delay may be normal when sending
or receiving some control commands on a low-speed
serial network. Cresnet networks with many devices
tend to exhibit more delay.
