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",
x.xx]]
The connected unit issues the appropriate copyright message
(above) when it rst powers on. x.xx is the rmware version
number.
AllX!]
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.
N 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).
FX1$]
The unit sends the F message whenever the switch mode is
changed from the front panel.
IlvlX!*X@]
The unit sends the Ilvl message whenever the level adjustment
is changed from the front panel.
IpekX!*X#]
The unit sends the Ipek message whenever the peaking
adjustment is changed from the front panel.
IseqX!*X%*X%*X%]
The unit sends the Iseq message whenever the skew settings
have been changed from the front panel. The X% values are the
red, green, and blue skew values, in that order.
Zpk]
The unit sends the Zpk message whenever the skew settings
have been reset from the front panel.
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 conguration]
Timeout
Pauses of 10 seconds or longer between command ASCII
characters result in a timeout. The command operation is
aborted with no other indication.
Using the command/response table
The command/response table begins on page 3-6. Lower
case letters are acceptable in the command eld except where
indicated for the audio level (gain and attenuation) commands.
Symbols are used throughout the table to represent variables
in the command/response elds. Command and response
examples are shown throughout the table. The ASCII to HEX
conversion table below is for use with the command/response
table.
