5. Button Control
5.1. Signal Switching
1) Press the SOURCE SELECT button to switch to the next source device, the
corresponding input LED will turn green.
2) Press and hold the SOURCE SELECT button for at least 3 seconds to enable
auto-switching mode, and it behaves by following theses principles:
⚫New input:
On detecting a new input signal, the transmitter will automatically switch to this
new signal.
⚫Signal removal
Once removing the current input signal, the transmitter will automatically switch
to another active HDMI input.
⚫Rebooting device
The transmitter can save the last configuration before losing power. If the last
switching mode is auto-switching, the transmitter will automatically enter 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 transmitter will switch to this input. If not, it will switch to the first
available active input source starting at HDMI IN 1.
⚫Exit auto-switching mode
Exit Auto-switch mode by pressing and holding the SOURCE SELECT button for
at least 3 seconds. Once in this mode, the wallplate will not changes inputs
automatically.
5.2. Display Control
1) Press the DISPLAY ON/OFF button to turn on and off the display.
2) The DISPLAY ON/OFF can be customized by sending RS232 commands for
compatibility with various displays.

6. RS232 Control
6.1. RS232 Connection
Depending on the RS232 control mode you are using, there are three possible
RS232 connections.
①When you are only controlling the transmitter, connect a control device (e.g. PC)
to the RS232 port of the transmitter, the connection diagram is shown below:

AVG-HD550
②When controlling a far-end third party device from local a control device (e.g.
PC), connect the PC to the RS232 port of the transmitter, and then connect the
third party device (e.g. projector) to the RS232 port of receiver. The connection
diagram is shown below:
③When you want to control a local third party device from the far-end control
device (e.g. PC), connect the PC to the RS232 port of the receiver, and then
connect the third party device to the RS232 port of transmitter. The connection
diagram is shown below:

AVG-HD550
6.2. RS232 Control Software
After connecting all your required input and output devices according to one of the
three methods, the RS232 control software needs to be installed into the control PC
to send RS232 commands.
⚫Installation Copy the control software file to the control PC.
⚫Uninstallation Delete all the control software files in corresponding file path.
Here take the software CommWatch.exe as example.
Double-click the following icon:
