5. Button Control
Front panel buttons can be used for signal switching, OSD, volume adjusting.
5.1 Manual Switching
Press the SOURCE/AUTO button to select one input source for Transmitter, press again
to select next source, switching sequentially between 1-HDMI, 2-HDMI, 3-DP and
4-VGA. The corresponding LED illuminates green.
The Receiver also features one HDMI input port, if you need to output the source signal
via its HDMI output port. The following is an example.
LED Status
Description
Status 1
The 1-HDMI LED illuminates green,
other source LEDs are gone.
The 1-HDMI is selected as input
source. The input signal will be
transmitted to all video output ports
of Transmitter and Receiver.
Status 2
The 2-HDMI and RX HDMI LEDs
illuminate green, other source LEDs
are gone.
The 2-HDMI is selected as input
source for Transmitter. The input
signal will be transmitted to all
video output ports of Transmitter.
The HDMI input signal on
Receiver will be only transmitted
to the HDMI output port of
Receiver.
Follow the below steps to switch to the status 2 from status 1.
①Press the SOURCE/AUTO button once to select 2-HDMI, and then release this
button.
②Press the SOURCE/AUTO button continuously until the RX HDMI LED illuminates
green to select the HDMI input for Receiver.

5.2 Auto Switching
Long-press SOURCE/AUTO button for 3 seconds or more to enable auto-switching
mode, and the auto-switching mode abides by the following principles:
New input
Once detecting a new input signal, the Transmitter would switch to this new signal
automatically.
Once connecting a source device to the HDMI IN port of Receiver, the Receiver will
switch to this source to output HDMI signal via HDMI OUT port automatically.
Rebooting device
The Transmitter have the ability to save the last configuration before losing power. If
the last switching mode is auto-switching, once rebooted, the Transmitter will
automatically enter auto-switching mode, then detect all inputs and memorize their
connection status for future rebooting using. If the last displayed signal is still
available, the unit will output the signal. If not, the unit will detect all the input signals
with priority from 1-HDMI to 4-VGA. When detected the first signal, it will transfer to
output.
Signal removing
Once removing the current display signal, the Transmitter will detect all input signals
with priority from 1-HDMI to 4-VGA. It will transfer the signal firstly detected to be
available to output devices.
Note:
Auto-switching function works only when inputting new signal, removing a signal or
power rebooting.
The HDMI input source on Receive cannot be selected under auto-switching mode.
5.3 Volume Adjustment
The Receiver features audio output ports for connecting speaker or AV amplifier.
Press the VOL+ or VOL- button on Transmitter to turn up or turn down the volume.
Meantime, it sends CEC commands to the display to turn up or down the display
volume.

6. RS232 Control
As RS232 commands can be transmitted to Receiver from the Transmitter, so it is able
to control the Transmitter or the third-party device (such as projector) on Receiver from
local.
The baud rate support 2400, 4800, 9600(default), 19200, 38400, 57600 or 115200.

Installation/uninstallation
Installation Copy the control software file to the computer connected with the
Transmitter.
Uninstallation Delete all the control software files in corresponding file path.
Basic Settings
First to connect the Transmitter with all input devices and output devices needed, then
to connect it with a PC which is installed with RS232 control software. Double-click the
software icon to run this software. Here we take the software CommWatch.exe as
example. The icon is showed as below:
