E14 – Invalid command at this time (input on/off command not
valid during contact closure mute)
E23 – Firmware update failure
Using the command/response table
The command/response table lists valid command ASCII codes,
the MVC’s responses to the host, and a description of the
command’s function or the results of executing the command.
Lower case characters are acceptable in the command field only
where indicated. The ASCII to HEX conversion table below is
for use with the command/response table.
ASCII to HEX Conversion Table

The command/response table uses symbols (defined below) to
represent variables.
The SIS on/off commands and the equivalent front panel
operations have equal priority. The MVC will respond
to the latest settings from either SIS commands or front
panel operations.
