The Crestron C2N-IO is a compact and versatile control port expansion module engineered to add essential connectivity to any Crestron 2-Series, 3-Series, or 4-Series control system via the Cresnet network. This small but powerful module provides integrators with the flexibility to incorporate additional control ports exactly where they are needed, whether behind a touch screen, inside a wall box, or mounted to any flat surface. By requiring just a single Cresnet cable for both power and communication, the C2N-IO enables clean, distributed installations without the need for bulky enclosures or separate power supplies. The C2N-IO provides one bidirectional RS-232 serial port for two-way device control and monitoring, one IR or serial output for infrared or one-way serial control, and two isolated relay ports for interfacing with screens, lifts, projection screens, and other contact-closure controlled devices. Status LEDs provide immediate visual confirmation of power and Cresnet communication, while rotary switches enable straightforward Cresnet ID configuration. With its metal enclosure and included mounting hardware, the C2N-IO delivers professional-grade reliability for residential and commercial automation applications. Read more
