5. Source Switching
1) Press the SELECT button to switch to next source device, and then the
corresponding input LED will turn green.
2) Press and hold the SELECT button at least 3 seconds to enable auto switching
mode, and it abides by the following principles:
⚫The switcher will switch to the first available active input starting at HDMI IN
1> HDMI IN 2.
⚫New input: Once a new input signal detected, the switcher will automatically
switch to this new signal.
⚫Source removed: When an active source is removed, the switcher will switch
to the first available active input starting at HDMI IN 1.
⚫Reboot: The switcher can save the last configuration before losing power. If
the last switching mode is auto switching, the switcher will automatically enter
ino auto switching mode once rebooted, then detect all inputs and memorize
their connection status for future rebooting using. If the last selected input
source is still available, the switcher will switch to this input. Otherwise, it will
switch to the first available active input source starting at HDMI IN 1.
⚫Exit auto switching mode: Press and hold the SELECT button for 3 seconds
again to exit the auto mode, and the input source will not be changed.
6. Video Resolution Down-scaling
The product supports video resolution down-scaling on 4 CAT outputs, the 4K input
can be automatically degraded to 1080p output for compatibility with 1080p display,
shown in the below chart.

7. IR Control
The IR receivers and emitters can be connected to the system to allow IR control of
remote devices. The bi-directional IR feature provides two-way control, either for the
source or display device(s). Below sample connection diagram is provided as
reference.
7.1 Controlling the Display Device by IR IN
The four IR IN ports of the Switcher can receive IR signals from the remote to control
displays. Connecting four IR receiver to IR IN ports of the Switcher, and then
connecting four IR emitters to IR OUT ports on receivers.
7.2 Controlling the Display Device by IR ALL IN
The IR ALL IN port of the Switcher can receive all IR signals from the remote to
control displays. Connecting an IR receiver to IR ALL IN port of the Switcher, and
then connect four IR emitters to IR OUT port on receivers.

AVG-UDA24-HD70
7.3 Controlling the Source Device
The IR OUT port of the Switcher can send all IR signals to control source device.
Connect four IR receivers to IR IN ports on receivers, and then connect an IR emitter
to IR OUT port of the Switcher.

AVG-UDA24-HD70

8. RS232 Control
The Switcher and compatible receivers features RS232 ports to transmit RS232
signals from computer to control far-end third-party devices by using 3-pin to DB9
cable and a RS232 control software, such as docklight. After installing the RS232
control software, please set the parameters of COM number, bound rate, data bit,
stop bit and the parity bit correctly. Compatible receivers must be able to
communicate at 9600, 19200, 38400, 57600, or 115200 baud. The Switcher requires
the following communication protocol parameters:
Baud rate: 9600 (default)
Data bit: 8
Stop bit: 1
Parity bit: none
Note:
⚫All commands need to be ended with “<CR><LF>”.
⚫In the commands, “[”and “]” are not needed to be typed in actual operation.
⚫Type the command carefully, it is case-sensitive.
