Unit-Initiated Messages
When a local event, such as a front panel operation, auto switch, or error condition,
occurs, the unit responds by sending a message to the host. The unit-initiated messages
are listed below:
(c)COPYRIGHT 2008, EXTRON ELECTRONICS “MTP SW6”, v.vv ]]
The connected unit issues the appropriate copyright message (above) when it first powers
on.
v.vv is the firmware version number.
ALL
X!
]
The unit sends the All message as a unit-initiated message under two conditions:
• You press a front panel input button.
• An input selection occurs via auto switch mode.
NOTE: The switcher returns the All message for every press of an input button, even if
no switch occurs. No switch will occur if you press an already selected button
or if the switcher is in auto switch mode (front panel input selection is disabled).

Error Responses
When the unit receives a valid SIS command, it executes the command and sends a
response to the host device. If the unit is unable to execute the command because the
command is invalid or it contains invalid parameters, the unit returns an error response to
the host. The error response codes are:
E10 - Invalid command
E11 - Invalid preset number
E13 - Invalid parameter
E14 - Invalid command for this configuration
