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. It can be mounted to any flat surface using two screws or adhesive reclosable fastener (3M® Dual Lock® included).
The C2N-IO is ideally designed for use with a Crestron touch screen control system (TPCS-4SM, TPCS-4SMD, or TSCW-730), providing an advanced wall mount control package that fits in a 2-gang US or UK electrical box. The C2N-IO can be mounted inside the electrical box behind the touch screen, or it can be installed remotely requiring just one Cresnet control cable for power and communications.
