3. System Connection
3.1 Usage Precautions
1) System should be installed in a clean environment with temperature and
humidity maintained to within equipment specification.
2) All of the power switches, plugs, sockets and power cords should be insulated
and safe.
3) All devices should be connected before power on.
3.2 System Diagram
The following diagram illustrates typical input and output connections that can be
utilized with the AVG-UHS41:

AVG-UHS41
3.3 Connection Procedures
Step1. Connect HDMI/ DVI source device(s) (e.g. Blu-ray DVD) to the HDMI INPUT
ports of AVG-UHS41 with HDMI cables.
Step2. Connect HDMI displays to the HDMI OUTPUT port of AVG-UHS41 with a
HDMI cable.
Step3. Connect an amplifier to the audio output port.
Step4. Connect an IR Receiver to the IR IN to enable IR control.
Step5. Connect the control device (e.g. a PC) to the RS232 port to enable RS232
control.
Step6. Plug a DC 5V power adapter to the power port of AVG-UHS41.
Note: All the ports support hot-plugging.
3.4 ARC Solution
The ARC (Audio Return Channel) enables a display, via a single HDMI cable, to
either send or receive audio via HDMI, upstream or downstream, depending on
system set-up and user preferences, increasing user flexibility. Connect the devices
as per the following figure:
Note: All utilized devices including the HDMI cable should support Audio Return
Channel functionality when connected to Audio Return Channel-enabled devices.
3.5 Application
Reliable performance for control and transmission makes the AVG-UHS41 ideal in
the IT computer space, signal monitoring, conference systems, television broadcast,
education, banking and security institutions etc.

AVG-UHS41
4. System Control
4.1 Front Panel Control
The SOURCE/AUTO button on the front panel can be used to change the input
source and select switch mode.
Switch input source: Press the button to switch through inputs 1~4, the
corresponding indicator illuminates green for monitoring.
Change the switch mode: Input signals support auto-switching and manual
switching. Press and hold SOURCE/AUTO button for 3 seconds or more to
switch between the two modes. (Default: Manual switching.)
In auto-switching mode, source selection abides by the following principles:
New input principle
Once detecting a new input signal, AVG-UHS41 switches to this new signal
automatically.
Power rebooting principle
Once rebooted, AVG-UHS41 will automatically select input 1 as input source
even if there is no connection to input 1.
Signal removing principle
Once a currently displayed signal is removed the AVG-UHS41 will detect all input
signals with a priority from INPUT 1 to INPUT 4. It will switch the first available
source to the output.
In manual-switch mode, once rebooted, AVG-UHS41 will output the source signal
before rebooting.
4.2 IR Control
Connect an IR receiver to the IR IN port, users can control the device via the
included IR remote. Here is a brief introduction to the IR remote:

AVG-UHS41
4.3 RS232 Control

UHS41 to the control device (e.g. a PC) with a RS232 cable and set the
communication parameters, the control device is then able to control the AVG-
UHS41 via control PC or other.
4.3.1 Installation/removal of RS232 Control Software
Installation: Copy the control software file to the computer connected with the AVG-
UHS41.
Removal: Delete all the control software files in the corresponding file path.
4.3.2 Basic Settings
Firstly, connect AVG-UHS41 with an input device and an output device. Then,
connect it with a computer which has installed 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:
MENU:
Mute: press to mute/ unmute output
Audio: switch between HDMI signal
and ARC audio
Source/Auto: share the same function
with SOURCE/AUTO button on the
front panel
INPUTS:
1~4: press to switch input source,
correspond to input 1~4 separately
Prev/ Next: switch to the previous/ next
input source in the order 1~4
