4-3TPX 88 Matrix Switchers • Programmer’s Guide

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)
