Switcher Error Responses

OutnnVolxx]

The switcher initiates the Vol message when a front panel output audio volume change has occurred. nn is the input number and xx is the volume 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 or RS-232 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.

Exen]

The switcher initiates the Exe message when the front panel Lock mode is changed from the front panel. n is the Lock mode: 0, 1, or 2. See “Setting the Front Panel Locks (Executive Modes“ for Lock mode definitions.

When the switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command is invalid or it contains invalid parameters, the unit 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)

E24 — Privilege violation (Ethernet, Extron software only)

Using the Command and Response Tables

The command and response table begins on page 65. Either uppercase or lower case letters are acceptable in the command field except where indicated for the audio level (gain and attenuation) commands. Symbols are used throughout the table to represent variables in the command and response fields. Command and response examples are shown throughout the table. The ASCII to HEX conversion table below is for use with the command and response table.
