The Crestron® CEN-IO-COM-102 is a compact and cost-effective wired I/O module designed to easily expand the available RS-232 ports within a commercial or residential system. A small form factor allows the CEN-IO-COM-102 to be placed just about anywhere, with the option to attach it to a flat surface or DIN rail using the included mounting bracket. The two onboard, bidirectional RS-232 COM ports enable direct integration with all kinds of third-party equipment.

The CEN-IO-COM-102 communicates to the local network using the available LAN connection, allowing the connected equipment to be remotely controlled and monitored from a computer or tablet. Power is conveniently supplied to the CEN-IO-COM-102 via PoE (Power over Ethernet) or a Crestron control system, eliminating the need for a local power supply or extra wiring.
