Vmtnn*x
The switcher initiates the Vmt message when a channel output mute is toggled on or off
from the front panel. nn is the output number and x is the mute status: 1 = on, 0 = off.

The switcher initiates the Exe message when executive mode is toggled on or off from the
front panel. n is the executive mode status: 1 = on, 0 = off.

Switcher Error Responses

When the switcher receives an SIS command and determines that it is valid, it performs the
command and sends a response to the host device. If the switcher is unable to perform
the command because the command is invalid or contains invalid parameters, the switcher
returns an error response to the host. The error response codes are:
E01 — Invalid input channel number (too large)
E10 — Invalid command
E11 — Invalid preset number
E12 — Invalid output number (too large)
E13 — Invalid value (out of range)
E14 — Illegal command for this configuration
E17 — Timeout (caused only by direct write of global presets)
E21 — Invalid room number
E24 — Privilege violation (Ethernet)

Using the Command/Response Tables

Symbols (variables), defined on the next page, are used throughout the command/response
tables. The symbols represent variables in the unit-initiated messages and the command/
response table fields. Letters in the command field are not case-sensitive. The table below
shows the hexadecimal equivalent of each ASCII character used in the command/response
table.
Space
