Outnn Volxx
The switcher initiates the Aud message when a front panel audio volume level
operation has occurred. "nn" is the output number and "xx" is the volume level.
Exen
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.
Amtn
The switcher initiates the Amt message when audio mute is toggled on or off for all
local audio outputs from the front panel. "n" is the mute status: 1 = on (muted),
0 = off (unmuted).
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 (only caused by direct write of global presets)
