MSG Matrix Switchers • Remote Control 5-5
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.
