MLC 226 IP Series • Setup Guide

The Extron MLC 226 IP Series MediaLink® Controller integrates Ethernet connection into

AV systems to allow users to remotely control, monitor, and troubleshoot AV equipment, including display devices and switchers. It includes an embedded web server, multiple serial ports, relays, and configurable digital I/O ports for use in applications that require control and monitoring of multiple devices within an AV system.

The MLC 226 IP series of controllers are configured using the free Extron Global Configurator (GC) software. The MLCs integrate seamlessly with Extron GlobalViewer® Enterprise (GVE) software and the free GlobalViewer web-based AV resource management software for remote control applications. Global Configurator and other useful software applications are available at www.extron.com.

A checklist of basic setup steps is provided at the end of this guide. For additional information see the help files and the MLC 226 IP Series User Guide, available at www.extron.com.
