Description
U2DM<d>VTS<vts>=<st>[,<p1>]<CR>
This command allows switching of the input
channels 1...6 of the digital automixer similar to a
talk station. The following states are available:
(VTS = virtual talk station)
1. ON: activates the input channel (Force On) and
sets the according logic output pin to high (e.g. for
an LED indicator).
2. OFF: deactivates the input channel (Force Off)
and sets the according logic output pin to low (e.g.
for an LED indicator).
3. REQUEST TO SPEAK: deactivates the input
channel (Force Off) and flashes the according
logic output pin with a frequency of 2 Hz (e.g. for
an LED indicator)
<ts> = channel number: 1…4
<st> = talks station state
0 = OFF
1 = ON
2 = REQUEST TO SPEAK (Logic Out
Pin toggles with 1 Hz)
optional:
<p1> = disables or enables the VTS function
0: Logic input pin is active
1: Logic input pin is not longer active
Note:
After sending this command, the input signals
“Force On” and “Force Off” for the according
channel are deactivated!
U2DM1VTS2=1<CR>
Activates channel 2 and sets the logic out pin of
channel 2 to high
U2DM<d>VTS<vts>=<st>
returns the status of the selected channel
<st>: VTS status of the channel
U2DM1VTS2=1<CR>
Device returns the status of channel 2:
<st>: = 1
U2DM1VTS2=0,0<CR>
Deactivates the VTS function at channel 2
U2DM1VTS2=0<CR>
Device returns the status of channel 2:
<st>: = 0 (after deactivating the VTS function the
returned status is not longer valid!)
