- Control port expansion module
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. The C2N-IO is ideally designed for use with a Crestron TPCS-4SM or TPCS-4SMD touch screen control system, 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.
