4. Operation
4.1. Front Panel Control
Front panel buttons can be used for switching operations, EDID and display control.
4.1.1. Manual Switching
When the switcher is in the manual switching mode, the Auto Mode LED goes out. If
need to change the input source, please directly press the 1, 2, 3 or 4 buttons, and
the corresponding LED illuminates green immediately.
4.1.2. Auto-Switching
Press and hold the AUTO button for at least 3 seconds to enable automatic
switching. Once enabled, the Auto mode LED illuminate.
When in Auto mode, the switcher will switch according to the following rules:
▪ The switcher will switch to the first available active input starting at input 1
through to input 4.
▪ New input: The switcher will automatically select the new input once detecting a
new input.
▪ Reboot: If power is restored to the switcher, it will automatically reconnect to the
last input it was on previously.
▪ Source removed: When an active source is removed, the switcher will switch to
the first available active input starting at 1-HDMI/MHL input.
▪ Press the Video Source button (1, 2, 3 or 4) can directly change the input source.
If the corresponding source device is active, it will be switched to as the input
source; otherwise, the switcher will switch to the first available active input
starting at 1-HDMI/MHL input.
▪ Press and hold the AUTO button for at least 3 seconds again will exit AUTO
mode. The input source will remain on the current source.
4.1.3. Display Control
The switcher supports CEC control. The DISPLAY CONTROL buttons on the front
panel are used for Display On/Off and volume control.
▪ ON: Display On.
▪ OFF: Display Off.
▪ : Mute/unmute display audio.
▪ : Volume down display audio.
▪ : Volume up display audio.
AVG-UHC41A
4.1.4. EDID Setting
The Extended Display Identification Data (EDID) is used for the source device to
match its video resolution with the connected display. By default, the source device
obtains its EDID from the first connected display. Meanwhile, since the displays with
different capabilities are connected to the switcher, the 4-pin DIP switch on the rear
panel can be used to set the EDID to a built-in fixed value. Use the following table to
determine the setting for the 4-pin DIP switch for specific video resolution and audio
capabilities.
The switch represents “0” when in the lower (OFF) position, and it represents “1”
while putting the switch in the upper (ON) position.

Third-party Device Control
The switcher supports RS232 pass-through control, the third-party device can be
controlled by RS232 command, and the command format as shown below:
Command
Function
Command Example
/+[B]:xxx.
xxx: ASCII string.
The “B” represents the baud rate
of third-party device.
B=1, the baud rate is 2400
B=2, the baud rate is 4800
B=3, the baud rate is 9600
B=4, the baud rate is 19200
B=5, the baud rate is 38400
B=6, the baud rate is 57600
B=7, the baud rate is 115200
/+3:123456.
Send the command “123456” to
the third-party whose baud rate
is 9600.
CMDON/+[B]:xxx.
Power on the third-party device.
CMDON/+3:455665.
CMDOFF/+[B]:xxx.
Power off the third-party device.
CMDOFF/+3:455666.
Note: When sending HEX commands in this box, the “/+[B]:” and the end mark “.”
must be converted to hexadecimal characters. For example, send the HEX
command “F0 01 01 02 0A” to the third-party whose baud rate is 9600. The “/+[3]:”
and the point “.” Is converted to “2F 2B 5B 33 5D 3A” and “2E”, thus the complete
HEX command is “2F 2B 5B 33 5D 3A F0 01 01 02 0A 2E”.
