Note:
a) Pictures shown in this manual are for reference only, models may vary slightly.
b) The Output HDCP compliant status depends on the input signal. When the input
signal is with HDCP, then output signal is with HDCP and vice versa.
c) HDMI signal contains both HDMI video signal and embedded audio signal (PCM,
Dolby Digital, DTS, DTS-HD), while the DVI signal contains only a video signal.
d) The AVG-UDA4 V2 can switch input signal formats according to the displays.
For example, when the input signal is HDMI and the display can only support a
DVI signal, the AVG-UDA4 V2 will change the signal to the DVI format.
e) EDID Management: automatically manages the output signal (e.g. output
resolution) to fit all displays.

4. System Connection
4.1 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.
4.2. Connection Diagram
The following diagram illustrates typical input and output connections that can be
utilised with the AVG-UDA4 V2.
4.3 Connection Procedure
Step1. Step 1. Connect an HDMI/ DVI source device (e.g. Blu-ray DVD) to the
HDMI INPUT socket of AVG-UDA4 V2 with a HDMI cable.
Step2. Connect the HDMI displays to HDMI OUTPUT sockets of AVG-UDA2 V2
with HDMI cables.
Step3. Plug a DC 5V power adapter to the power port of AVG-UDA4 V2.
Note: All the ports support hot-plug. It’s important to know that hot plugging a display
may result in splash screen at the output ends.

4.4 EDID Management
The AVG-UDA4 V2 features 1 HDMI input port and 2 HDMI output ports. It also
features built-in EDID management.
1. When all output ports are connected to the displays, the source device will
acquire the EDID data from the display connected to the output 1 port. At this
point, if you disconnect the output 1 display and want the source device to gain
the EDID from output 2, the AVG-UDA4 V2 will need to be restarted.
2. All connected displays should be compatible, for example: when output 1
connects with a 1080p display, the AVG-UDA4 V2 will select 1080p as output
resolution and distribute 1080p signal to the displays connected to outputs 1~2. If
the display connected to output 2 doesn’t support a 1080p signal, there will be no
output on the display.
4.5 Application
Robust performance for signal transmission makes the AVG-UDA4 V2 ideal in the
custom installation industry, IT computer space, signal monitoring, big screen
displays, conference systems, television broadcast, education, banking and security
institutions etc.
