Screen Enable/Disable
Disable all screens
Disables all screens so they do not display a picture (most screens will go into standby
mode). This is intended to blank all screens when not in use, overnight etc.
GET /cgi-bin/api?screen1=0 HTTP/1.1
Enable all screens
Enables all screens so they display a picture. This is the opposite of disable all screens and
is used to restore the display which was previously disabled. This command will enable all
screens, regardless of whether they were disabled by the disable all screens command or
disable individual screen command.
GET /cgi-bin/api?screen1=1 HTTP/1.1
Disable individual screen
Disable an individual screen so it does not display a picture (most screens will go into
standby mode). The screen is identied by the port number (1..4) of the ALDV104T to
which it is attached. This is intended to blank all screens when not in use, overnight etc.
GET /cgi-bin/api?port=1?screen1=0 HTTP/1.1
GET /cgi-bin/api?port=2?screen1=0 HTTP/1.1
GET /cgi-bin/api?port=3?screen1=0 HTTP/1.1
GET /cgi-bin/api?port=4?screen1=0 HTTP/1.1
Enable screen
Enables an individual screen so it displays a picture. This is the opposite of disable
screen command and is used to restore the display which was previously disabled. This
command will enable a screen , regardless of whether it was disabled by the disable all
screens command or disable individual screen command.
GET /cgi-bin/api?port=1?screen1=1 HTTP/1.1
GET /cgi-bin/api?port=2?screen1=1 HTTP/1.1
GET /cgi-bin/api?port=3?screen1=1 HTTP/1.1
GET /cgi-bin/api?port=4?screen1=1 HTTP/1.1
Set source for EDID for input
The EDID presented on each input is either the default one built in to the ALDV104T or
is obtained from one of the screens connected to a connected ALDV100R. The source of
the EDID for each of inputs 1 and 2 is controlled individually. There are three options
• Default – built in EDID,
• Clone from display – copy EDID from selected display and always use this EDID,
• Transparent from display – copy EDID from selected display and re-read from display
every time the display is re-connected. This allows the EDID to change dynamically if a
different display is connected.
Set to Default EDID
Use the built in default EDID for the input. The emod1 parameter controls input 1, emod2
controls input 2.
To select this mode emod1/emod2 = 0.
GET /cgi-bin/api?emod1=0 HTTP/1.1
GET /cgi-bin/api?emod2=0 HTTP/1.1
Clone from display
Copy the EDID from the selected display and always use it for this input. The esrc1
parameter is used when controlling the EDID for input 1, esrc2 controls input 2. The
value of the esrc parameter is the port number (1..4) on the ALDV104T through which
the selected display is connected. To select this mode emod1/emod2 = 1.
GET /cgi-bin/api?emod1=1&esrc1=1 HTTP/1.1
GET /cgi-bin/api?emod2=1&esrc2=1 HTTP/1.1
This example shows the EDID obtained from the display on port 1. Similarly esrc1/2 =
2,3 or 4 to select the screen connected to ports 2,3 or 4
Transparent from display
Copy the EDID from the selected display and re read it whenever the display becomes
active. This allows the EDID to change dynamically if a different display is connected to
the selected port. The esrc1 parameter is used when controlling the EDID for input 1,
esrc2 controls input 2. The value of the esrc1/esrc2 parameter is the port number (1..4)
on the ALDV104T through which the selected display is connected. To select this mode
emod1/emod2 = 2.
GET /cgi-bin/api?emod1=2&esrc1=1 HTTP/1.1
GET /cgi-bin/api?emod2=2&esrc2=1 HTTP/1.1
This example shows the EDID obtained from the display on port 1. Similarly esrc1/2 =
2,3 or 4 to select the screen connected to ports 2,3 or 4
