        C2N-IO

        Control Port Expansion Module

        An outboard module for adding control ports to a Crestron® touch screen control system or any other Crestron control systems.

        The C2N-IO is a very compact device that adds control ports to any Crestron 2-Series 3-Series®, or 4-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).

         
        Key Features
        • Fits within a 2-gang wall box
        • Provides 1 RS-232, 1 IR/serial, and 2 relay ports1
        • Compatible with any Crestron 2-Series, 3-Series®, or 4-Series® control system
        • Interfaces via the Cresnet® control bus
        • 24 VDC Cresnet powered
        • Surface mount bracket included
        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.
