Innn Audxx
The switcher initiates the Aud message when a front panel input audio level
change has occurred. “nn” is the input number and “xx” is the dB level.
Vmtnn•x
The switcher initiates the Vmt message when a video output mute is toggled on or
off from the front panel. “nn” is the output number, • is a space, and “x” is the
mute status: 1 = on, 0 = off.
Amtnn•x
The switcher initiates the Amt message when an audio output mute is toggled on
or off from the front panel. “nn” is the output number, • is a space, and “x” is the
mute status: 1 = on, 0 = off.
Exen
The switcher initiates the Exe message when front panel lock is toggled on or off
from the front panel. “n” is the front panel lock 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 (too large)
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)
E22 — Busy
E25 — Device not preset
E28 — Bad filename/File not found
Using the Command/Response Table
The command/response tables begin on page 4-5. Lower case letters are acceptable
in the command field except where indicated for the gain and attenuation
commands. The table below shows the hexadecimal equivalent of each ASCII
character used in the command/response table.
Symbols are used throughout the table to represent variables. Command and
response examples are shown throughout the table.
