Button Control
Front panel buttons can be used for signal switching, OSD, volume adjusting.
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.
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 switcher
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 removal
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.
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.

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.
