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.

RX HDMI SOURCE
AUTO/3s
1-HDMI 2-HDMI 4-VGA3-DP
RX HDMI SOURCE
AUTO/3s
1-HDMI 2-HDMI 4-VGA3-DP

Follow the below steps to switch to the status 2 from status 1.

1. Press the SOURCE/AUTO button once to select 2-HDMI, and then release this button.
2. Press 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.
When in AUTO switch mode, the display’s LED may not show the correct status due to the presence of the RX HDMI input –this is normal behaviour. If the user needs to show the correct LED status, please manually switch the input source on the Transmitter (TX).

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.

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.
