4.2.4 EDID Management
The KanexPro HDMX88-4K provides a convenient EDID management to create
effective communication between the display and sources.
In factory default status (Status: 0000), the switcher will pass through the signals directly,
input & output device process the signal automatically. You can invoke other saved
EDID data by adjusting the 4-pin EDID DIP switcher or sending corresponding RS232
command.
4.2.4.1 Via RS232 commands
Dial the switchers to “1111” to enable software EDID management.
$Invoking embedded EDID data:
Send command “EDID[X]B[y].” to enable input to invoke embedded EDID data of the
Matrix Switcher. For example, send “EDID[4]B[3]” , the INPUT device (4) will gain
embedded EDID data is that 720P 2D 2CH.
$EDID Copy:
Send command “EDIDM[X]B[y].” to enable input to copy the EDID data of a display. For
example, send “EDIDM[1]B[5]” , the INPUT device (1) will gain EDID data from

8x8 HDMI Matrix Switcher with 4K/60 & HDCP2.2
11
OUTPUT device(5).
$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 command EDIDUpgrade[x].
Refer to 4.2.3 RS232 Communication Commands for more EDID management
commands (with grey background).
4.2.4.2 Via 4-pin EDID DIP switcher
Beside EDID can be managed via RS232 commands, the matrix switcher includes a
4-pin EDID DIP switcher to manage EDID. Dial the switchers to invoke demanded EDID
data.
$Embedded EDID data: 10 sets in total, the chart below illustrate the 10 Embedded
EDID data.
$Custom EDID data: max at 3 sets
The chart below shows switcher status for custom EDID No.12~14.

4.3 TCP/IP Control
4.3.1 Control Modes
TCP/IP default settings: IP is 192.168.0.178, Gateway is 192.168.0.1, and Serial Port is
8080. IP can be changed as you need, Serial Port cannot be changed.
•Controlled by single PC
Connect a computer to the TCP/IP port of the 8x8 Matrix Switcher, and set its network
segment to the same as the default IP of the Matrix Switcher (192.168.0.178).
Figure 4- 3 modify the IP of PC
•Controlled by PC(s) in LAN
The HDMX88-4K can be connected to a router to make up a LAN with the PC(s), this
makes it capable to be controlled in a LAN. When control, just make sure the Matrix
Switcher’s network segment is the same as the router. Please connect as the following
figure for LAN control.
Same network
segment as the
switcher

8x8 HDMI Matrix Switcher with 4K/60 & HDCP2.2
13
Figure 4- 4 Connect to LAN
Step1. Connect the TCP/IP port of the Matrix Switcher to Ethernet port of PC with
twisted pair.
Step2. Set the PC’s network segment to the same as the Matrix Switcher. Do please
remember the PC’s original network segment.
Step3. Set the Matrix Switcher’s network segment to be the same as the router.
Step4. Set the PC’s network segment to the original one.
Step5. Connect the Matrix Switcher and PC(s) to the router. In the same LAN, each
PC is able to control the Matrix Switcher asynchronously.
Then it’s able to control the device via TCP/IP communication software.
4.3.2 Control the HDMX88-4K via TCP/IP communication software
(Exampled by TCP/UDP software)
1) Connect a computer with TCPUDP software to the Matrix Switcher. Open the
TCPUDP software (or any other TCP/IP communication software) and create a
connection, enter the IP address and port from the Matrix Switcher-N (default IP:
192.168.0.178, port: 8080):
