SIS ™ Programming and Control

The MLC 104 Plus 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
Config/RS-232 port or LAN port, or the front panel Config port.
The MLC 104 Plus Series units must be configured 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 configured.
The MLC can be set up and controlled by using Extron’s Simple Instruction Set
(SIS) commands or the Extron Global Configurator software (version 2.2 or higher
for IP models, version 2.5 or higher for MLC 104 Plus), and both of those methods
can be accessed via RS-232 (all models) or Ethernet LAN connection (IP models).
See chapter 2 for pin assignments and other details on the configuration and control
ports. For information on the software and the MLC 104 IP Plus’s embedded Web
pages, see chapter three.
MLC 104 Plus Series RS-232 protocol:
• 38400 baud
• 8 data bits
• 1 stop bit
• no parity
• no flow control
N The configuration port requires 38400 baud communication. This is a
higher speed than many other Extron products use. The Global Configurator
(version 2.2 or higher for IP models, version 2.5 or higher for MLC 104 Plus)
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 (IP models):
• MLC’s IP address: 192.168.254.254
• gateway’s IP address: 0.0.0.0
• subnet mask: 255.255.0.0
• DHCP: off
Host-to-MLC Communications
SIS commands consist of one or more characters per field. 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 via RS-232 or via a verbose ( see page 4-21 )
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).
Chn
X!] (where X! is the input number)
The unit sends this response when an input is switched.
