RS-232 Commands
Control Commands
Code Function Operation
Level You can skip leading zeros on values – so 5 can be 5, 05 or 005
VL= Stereo input volume 0 (mute) to 63 (full)
VM Stereo input mute on Mutes input
VX Stereo input mute off Restores volume to previous level
VU Ramp volume up Starts volume ramping up
VD Ramp volume down Starts volume ramping down
VV Stop volume ramp Stops volume ramping
VT Toggle Volume Mute Alternates audio mute on and off
VG= Amplifier Gain Sets gain level
Sent alone returns amp gain status
0=20 dB (default)
1=26 dB
2=32 dB
3=36 dB
Inputs Volume Parameter “Bump” Send input volume parameter with 255 will bump value to next
step. Send parameter with 254 will bump value down one step
This allows wall panels that can’t send a volume ramp from
press and a ramp stop from release to just bump the level up
with each button press.
V0= Stereo Input Stated with <parameter>,<value>
V0 alone will return status for Stereo
(xx)=Default setting
1=Volume level 1-63 (40)
2=Max gain level 0-63 (0-63, also acts as mute on/off)
3=Min gain level 0-63 Fixed at 0, variable in future
4=Power On Threshold 0-63 (4)
5=Power On Hold delay 0-99 seconds (99) 0=Always On
Ex: ‘>V0=1,30’
V1= Mono 1 Stated with <parameter>,<value>
V1 alone will return status for Input 1
Input 1 always has priority for ducking
(xx)=Default setting
1=Volume level 0-63 (40)
2=Max gain level 0-63 (0-63, also acts as mute on/off)
3=Min gain level 0-63 (Fixed at 0), variable in future
4=Gating threshold level 1-63 (10)
5=Gating hold time 0-50 in 0.1 seconds (15)
00=Ducking off, acts as mixed input
6=Ducking level for the stereo input 0-63 (10)
Example: ‘>V1=1,20 V1=4,03 V1=5,10 V1=6,05’
V2= Mono 2 Stated with <parameter>,<value>
V2 alone will return status for Input 2
(xx)=Default setting
1=Volume level 0-63 (40)
2=Max gain level 0-63 (0-63, also acts as mute on/off)
3=Min gain level 0-63 (Fixed at 0), variable in future
4=Gating threshold level 1-63 (10)
5=Gating hold time 0-50 in 0.1 seconds (15)
00=Ducking off, acts as mixed input
6=Ducking level for the stereo input 0-63 (10)
SV Amp Status Returns Amp/Stereo status string
