Using Simple Instruction Set (SIS) Commands
Host-to-MGP communications
The MGP accepts SIS (Simple Instruction Set) commands through the RS-232/422
port on the rear panel, the RS-232 front panel Config port, and the LAN port. SIS
commands consist of one or more characters per command field. They do not
require any special characters to begin or end the command character sequence.
Each response to a command ends with a carriage return and a line feed (]), which
signals the end of the response character string. A string is one or more characters.
MGP-initiated messages
When a local event such as a front panel selection or adjustment takes place, the
MGP 464 responds by sending a message to the host. No response is required from
the host. Examples of MGP-initiated messages are listed below (underlined).

or
(c) Copyright 2009, Extron Electronics, MGP462xi, Vx.xx 60-1023-xx
The MGP sends the copyright message when it is first powered on. Vx.xx
is the firmware version number, and 60-771-xx or 60-1023-xx are the part
numbers for the MGP 464 or the MGP 462xi series, respectively.

Out n In nn (where Out n is the window number, and In nn is the input number).
The MGP sends this response when an input is switched.
Error responses
When the MGP 464 receives a valid SIS command, it executes the command and
sends a response to the host device. If the processor is unable to execute the
command because the command is invalid or contains invalid parameters, it
returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (too large)
E09 — Invalid function number (too large)
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number (applies for addressing windows)
E13 — Invalid value (out of range)
E14 — Invalid for this configuration
E17 — Invalid command for signal type
