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.[1] 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.



  • Fits within a 2-gang wall box behind the TPCS-4SM(D) or TSCW-730
  • Provides 1 RS-232, 1 IR/serial, and 2 relay ports [1]
  • Compatible with any Crestron® 2-Series or 3-Series® control system

  1. 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.
