Extron electronic MSG0804 Switching commands, Volume commands, Switching levels audio models only

Switching commands

These commands can only initiate a one-input-to-one-output switch.

Switching levels (audio models only)

Switching levels consist of combinations of video (RGB), sync (HV), and audio boards. The three predefined switching levels include:

•Level 1 = RGBHV and audio

•Level 2 = RGBHV (no audio)

•Level 3 = Audio only (no video or sync)

For commands that use these switching levels, refer to the Switching Commands
chart below.
Command	Description
Set switching level
[LVLx]	x = set switching level (1 to 3)
	x = ? returns current switching level
Execute matrix switch
[MSxOooIii]	Executes a matrix switch of an input to an output for a
	specific switching level.
	• Where:
	x = 1 - 3 for specific switching level.
	oo = 01 - 04 (MSG0804) or 01 - 08 (MSG0808) for output.
	ii = 00 - 08 for input (00 = blank)
Matrix switch current setting
[MSx?]	Returns the current connections for level x.
Matrix switch current output
[MsxOoo?]	Returns connections for specified output and level.
	• Where:
	x = switching level.
	oo = 01 - 04 (MSG0804) or 01 - 08 (MSG0808)
Blank output
[BLANKoo]	Blanks a specific output.
	• Where oo = 01 - 04 (MSG0804) or 01 - 08 (MSG0808)

Volume commands

Use these commands to control volume levels for both inputs and outputs. Input levels are typically adjusted to minimize drastic changes in volume when switching between inputs.

Command	Description
Mute/unmute
[MUTEoox]	Mute or unmute a specific output or request the current
	status.
	• Where:

oo = 01 - 04 (MSG0804) or 01 - 08 (MSG0808) for output. x = 0 to disable mute and 1 to enable mute.

x = ? to request the current state.

x = (blank) to toggle the current state.
