10.8.10. Set analog input audio parameters
Description: This command changes the setup of the ADC on the audio board.
Format
Example
Command
{:AUDIN#<in>@<S/A>I=<VOL>;
<BAL>;<GAIN>;<PHS>;<DCF>}
→
{:audin#2@si=0;50;0;0;0;}
Response
(:AUDIN#<in>@<S/A>I=<VOL>;
<BAL>;<GAIN>;<PHS>;<DCF>)CrLf
←
(AUDIN#2@SI=0;50;0;0;0;)CrLf
Legend: <S/A>: Affected ports:
S = single selected output
A = all outputs
<VOL>: Volume: (default 0}
0, 100, 200, .. , 6200, 6300
where 0 = 0 dB, 6300 = - 63 dB
<BAL>: Balance: (default 50)
0 .. 100 %
<GAIN>: Gain: (default 0)
0, 3, 6, .. , 21, 24 dB
<POL>: Polarity inversion: (default 0)
0 = Normal (phase=0°),
1= Inverted (phase=180°)
<DCF>: Audio DC filter: (default 0)
0 = DC filter off,
1 = DC filter on.
10.8.11. Query analog input audio properties
Description: This command reads the setup of the ADC on the audio board.
Format
Example
Command
{:AUDIN#<in>@<S/A>I=?}
→
{:audin#2@si=?}
Response
(:AUDIN#<in>@<S/A>I=<VOL>;
<BAL>;<GAIN>;<PHS>;<DCF>)CrLf
←
(AUDIN#2@SI=0;50;0;0;0;)CrLf
Legend: Please read section 10.8.10 on page 90.
10.8.12. Set the no sync picture properties
Description: If there is no incoming video signal on the selected input and this function is
enabled the device gives a monochrome 640x480p60 picture to the output. This
command enables/disables this function and sets the color of the no sync picture with an
RGB value on the active input port.
Format
Example
Command
{:SETBG#<in>@<S/A>I=
<RED>;<GREEN>;<BLUE>;<nss>}
→
{:setbg#1@si=255;255;0;1}
Response
(SETBG#1@SI=
<RED>;<GREEN>;<BLUE>;<nss>)CrLf
←
(SETBG#1@SI=255;255;0;1)CrLf
Legend: <S/A>: Affected ports:
S = single selected input
A = all outputs
<RED> Red component of RGB value.
<GREEN> Green component of RGB value.
<BLUE> Blue component of RGB value.
<nss> No Sync screen enable
0 = No Sync screen disable
1 = No Sync screen enable
Explanation: The example shows how to enable and set yellow colored monochrome no
sync picture on the DVI-D input port.
Info: Enabling/Disabling or setting of the color of no sync picture is available only on the
selected active input.
