3.1. Usage Precautions

1. The system should be installed in a clean environment that has proper

temperature and humidity.

2. All the power switches, plugs, sockets and power cords should be insulated and
safe.

3. All devices should be connected before powering it on.

3.2. System Diagram

4. Operation

4.1. Front Panel Control

Front panel buttons can be used for switching operations, OSD and volume control.

4.1.1. Manual Switching

Press the SOURCE/AUTO button to select an input for the Transmitter, press again
to select next source, switching sequentially between 1-HDMI, 2-HDMI, 3-DP and 4­VGA. The corresponding LED will illuminate 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.
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.

4.1.2. Auto-Switching

Long-press the SOURCE/AUTO button for 3 seconds or more to enable auto­switching mode. The auto-switching mode works as follows:

 New input

Once the Transmitter detects a new input signal and it isn’t already locked onto
an input, it will switch to this new signal automatically.

 Rebooting device

The Transmitter can 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 use. If the last displayed signal is still
available, the unit will output that signal. If not, the unit will detect any other input
signals with priority from 1-HDMI to 4-VGA. When the next available signal has
been detected it will switch this to the output.

 Signal removing

On removal of the current source signal, the Transmitter will detect all input
signals with priority from 1-HDMI to 4-VGA. It will switch to the next available
input.

Note:

 Auto-switching function works only when connecting a new signal, removing a

signal or power cycling.

 The HDMI input source on Receive cannot be selected under auto-switching

mode.

4.1.3. Volume Control

The Receiver features audio output ports for connecting speakers or an AV amplifier.
Press the VOL+ or VOL- button on Transmitter to turn up or turn down the volume.

AVG-SC41T-CODEC

4.3. RS232 Control

As RS232 commands can be transmitted to the 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.
