The MLC 226 IP Series controller can be remotely set up and controlled via a host
computer or other device (such as a control system) attached to the rear panel
Confi g/RS-232 port or LAN port, or the front panel Confi g port.
The MLC 226 IP
must be confi gured before use.
As shipped the controller can
trigger basic input switching on an optional MLS switcher, but it cannot control any
other devices before being confi gured.
The MLC 226 IP can be set up and controlled by using Extron’s Simple Instruction
Set (SIS) commands or the Extron Global Confi gurator software (version 2.2 or
higher), and both of those methods can be accessed via RS-232 or Ethernet LAN
connection. See chapter 2, “Installation,” for pin assignments and other details on
the confi guration and control ports. For information on the software and the MLC
226 IP’s embedded Web pages, see chapter four.
MLC 226 IP’s RS-232 protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no fl ow control
N
Both
confi guration ports require 38400 baud communication. This is a higher
speed than many other Extron products use. The Global Confi gurator (version
2.2 or higher) software automatically sets the connection for the appropriate
speed. If using HyperTerminal or a similar application, make sure the PC or
control system connected to these ports is set for 38400 baud.
LAN port defaults:
•
MLC’s IP address:
192.168.254.254
•
gateway’s IP address:
0.0.0.0

Host-to-MLC Communications
SIS commands consist of one or more characters per fi eld. No special characters
are required to begin or end a command sequence. When the MLC determines
that a command is valid, it executes the command and sends a response to the host
device. All responses from the MLC to the host end with a carriage return and
a line feed (CR/LF =
]
), which signals the end of the response character string.
A string is one or more characters.
MLC-initiated messages
If you are communicating with the MLC 226 IP via RS-232 or via a verbose Telnet
connection, when a local event such as a front panel selection or adjustment takes
place, the MLC responds by sending a message to the host. No response is required
from the host. The MLC-initiated messages are listed here (underlined).

X!

The unit sends this response when an input is switched.
