Configuring The Mlc For Network Communication; Configuring The Mlc For Network Use Via Global Configurator - Extron electronics MLC 104 IP Plus Series User Manual

Configuring the MLC for Network Communication

To function together, both the PC and the MLC must be configured correctly. Unless you
use an RS-232 connection for all setup and communication with the controller, the PC must
be network-capable with the proper protocols, and the MLC must be set up so it can be
connected to a LAN or other network. When you power on the MLC for the first time, you
have a choice of several ways to set up the IP address:
•
•
•
•
•
If you use a web browser or Telnet the first time you connect a PC to an MLC via IP,
you may need to temporarily change the IP settings of the PC in order to communicate with
the controller. See
on page 40.
Then you must change the default settings (IP address, subnet mask, and [optional]
administrator name and password) on the MLC in order to use the unit on an intranet (LAN)
or on the Internet. After you have set up the MLC for network communication, you can reset
the PC to its original network configuration.

The following instructions assume that you have already connected the PC to the LAN port
or the Config port on the MLC and powered on the controller and the PC.

Configuring the MLC for Network Use Via Global Configurator

You can configure the IP address of the controller via an IP (Ethernet) connection using the
Extron Global Configurator (GC) software. See the Global Configurator Help file for basic
Use the Global Configurator software via the LAN connector.
Use the ARP (address resolution protocol) command via the LAN connector.
Use a web browser via the LAN connector.
User SIS commands via an RS-232 connection.
Use SIS commands via Telnet and the LAN connector.

automatically set the connection for the appropriate speed. If using DataViewer,
HyperTerminal, or a similar application, make sure the PC or control system
connected to this port is set for 38400 baud.
