SAFETY OPERATION GUIDE
In order to guarantee the reliable operation of the equipment and safety of the
user, please abide by the following procedures in installation, use and
maintenance:
1. The system must be earthed properly. Please do not use two blade plugs
and ensure the AC power supply ranges from 100v to 240v and from 50Hz
to 60Hz.
2. Do not install the switcher in an environment where it will be exposed to
extreme hot or cold temperatures.
3. This unit will generate heat during operation, please ensure that you allow
adequate ventilation to ensure reliable operation.
4. Please disconnect the unit from mains power if it will be left unused for a
long period of time.
5. Please DO NOT try to open the casing of the equipment, DO NOT attempt to
repair the unit. Opening the unit will void the warranty. There are high
voltage components in the unit and attempting to repair the unit could result
in serious injury.

5. System Operations
5.1 I/O Connection Switching
The front panel features four input and output selection buttons for switching the I/O
connection.
1) To swicth one input to an output:
Operation: “input” + “output” + “ENTER”
Example: input 2 to output 4
INPUT: OUTPUT:
2) To switch an input to several outputs:
Operation: “input” + “output” + “output” +… + “ENTER”
Example: Switch input 2 to output 2, 4
INPUT: OUTPUT:
Note:Indicators of the pressed buttons will blink blue three times if the switching is
successful, then turn off. If the switch fails, they will turn off immediately.
5.2 I/O Connection Query
Press and hold the button ENTER for 3 seconds to enter system enquiry mode, and
then press INPUT 3/4 to select previous/next item, press INPUT 1/2 to turn
previous/next page. The chart below shows information that can be inquired:

5.3 EDID Management
AVG-UHD4K-88 V2 features EDID management to maintain compatibility between
all devices. It can be controlled via EDID learning and EDID programming.
EDID Learning (from output)
One input port learns the EDID data of one output port
Operation: Press “EDID”, “INPUTS”+“OUTPUTS”+“ENTER”.
Example: Input 2 learns EDID data from output 4
OUTPUT: OUTPUT:
All input ports learn EDID data from one output port
Operation: Press “EDID”, “ALL” + “OUTPUTS” + “ENTER”
Example: All input ports learn EDID data from output 4

Note: Indicators of the pressed buttons will blink blue three times if the process is
successful, then they will turn off. If the process fails, they will turn off
immediately.

5.6 TCP/IP Control
5.6.1 Control Modes
TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and TCP Port
is 4001. The IP address can be changed as required, the TCP Port cannot be
changed.
Control via a single PC
Connect a computer to the TCP/IP port of the AVG-UHD4K-88 V2, and set its
network address in the same range as the default IP of the Matrix (192.168.0.178).
Set the Subnet mask to 255.255.255.0 and no gateway IP address is required.
Control by PC(s) in LAN
The AVG-UHD4K-88 V2 can be connected with a router to make up a LAN with the
PC(s), this allows it to be able to be controlled in a LAN. When controlling in this
manor, just make sure that the AVG-UHD4K-88 V2’s network subnet is the same as
the routers. Please connect as per the following figure for LAN control.
Connect to LAN
Step1. Connect the TCP/IP port of the AVG-UHD4K-88 V2 to an Ethernet port of the
PC with twisted pair.
Step2. Set the PC’s network subnet to the same as the Matrix Switcher. Please
remember the PC’s original network subnet setting.
Step3. Set the AVG-UHD4K-88 V2’s network subnet to the same as the router.
Step4. Set the PC’s network subnet to the original setting.
Step5. Connect the AVG-UHD4K-88 V2 and PC(s) to the router. In the same LAN,
each PC is able to control the AVG-UHD4K-88 V2 asynchronously.
Control is then possible via the TCP/IP communication software.
