Setting up the PC for IP communication with an MLC
You need a Windows-based (Windows 2000, XP, or higher) PC equipped with an
operating network adapter. To allow your PC to work with Extron’s Ethernet-
controlled products, the TCP/IP protocol must be installed and properly
confi gured.
When setting up the MLC for network communication via a Web browser or Telnet
connection, you must change the IP address of the PC to one that is on the same
subnet as the MLC. This is not required if you are setting up the MLC for network
communication via Global Confi gurator, the ARP command, or SIS commands via
an RS-232 connection.
If you use an existing Ethernet LAN intranet, your network administrator can
provide you with a unique IP address for the controller or confi rm whether you
need to set up the MLC 226 IP for DHCP (Dynamic Host Confi guration Protocol) to
have an address assigned automatically when you sign on.
1. Open the Network Connections page as follows:

Places on the Windows (2000, XP,
or higher) desktop, then click on

or
