5.2.4 EDID Management
The AVG-UHD4K-88 ships with a convenient EDID management table to facilitate
effective communication between the displays and sources.
In factory default status (Status: 0000), the AVG-UHD4K-88 passes through the
signals directly, input & output devices process the signal automatically. You can
recall other saved EDID data by adjusting the 4-pin EDID DIP switcher or sending
the corresponding RS232 commands.
5.2.4.1 Via RS232 commands
Dial the switchers to “1111” to enable software EDID management.
Recalling embedded EDID data:
Send command “EDID[X]B[y].” to enable the input to recall the embedded EDID
data of the AVG-UHD4K-88 . For example, send “EDID[4]B[3]” , the INPUT device
(4) will gain embedded EDID data is that 720P 2D 2CH.
EDID Copy:
Send the command “EDIDM[X]B[y].” to enable the input to copy the EDID data of a
display. For example, send “EDIDM[1]B[5]” , the INPUT device (1) will gain the
EDID data from OUTPUT device(5).

AVG-UHD4K-88
Program Custom EDID data:
Copy custom EDID data (.bin) to the control device (e.g. a PC) and program the data
into the device by sending the command EDIDUpgrade[x].
Refer to 4.2.3 RS232 Communication Commands for more EDID management
commands (with grey background).
5.2.4.2 Via 4-pin EDID DIP switcher
Beside the software managed EDID table, the AVG-UHD4K-88 has a 4-pin EDID
DIP switcher to manage EDID. Select the switches to recall corresponding EDID
data
Embedded EDID data: 10 sets in total, the chart below illustrate the 10
Embedded EDID data options.
Custom EDID data: max of 3 sets

AVG-UHD4K-88
Connect a computer to the TCP/IP port of the AVG-UHD4K-88, and set its network
subnet to the same as the default IP of the Unit (192.168.0.178).
Figure 5- 4 Modify the IP of PC
Controlled by PC(s) in LAN
The AVG-UHD4K-88 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’s network subnet is the same as the
routers. Please connect as per the following figure for LAN control.
Figure 5- 5 Connect to LAN
Step1. Connect the TCP/IP port of the AVG-UHD4K-88 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’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 and PC(s) to the router. In the same LAN,
each PC is able to control the AVG-UHD4K-88 asynchronously.
Control is then possible via the TCP/IP communication software.
