Quick Start
The Crestron® CEN-IO-COM-102, CEN-IO-DIGIN-104, CEN-
IO-IR-104, and CEN-IO-RY-104 allow for easy expansion of
I/O ports within a system. Distribute these wired Ethernet
modules anywhere in the installation via an available LAN
connection.
The CEN-IO-COM-102, CEN-IO-DIGIN-104, CEN-IO-IR-104,
and CEN-IO-RY-104 share a similar installation procedure.
For simplicity within this guide, the term CEN-IO is used
except where noted.
