2. Connect one HDMI Cable between the HDMI inpu port of display and the HDMI output port of Receiver
unit.
3. Connect one CAT5e or better cable between the RJ45 of each Transmitter unit and RJ45 port of
Gigabit Ethernet switch hub.
4. Connect over each RJ45 port of Gigabit Ethernet switch hub with RJ45 port of Receiver unit.
5. Use DIP switch to select sources, User can select source channel by DIP switch setting on each
transmitter unit and set up DIP switch on each receiver. And select display devices for Receiver units
via one remote control
Important: Please make sure power on the POE switch rst , then power on the
source !
Now, If you need display Source2 on TV1, then just set Group ID of RX1 0101,same as TX2: 0101 (refer
to Diagram).
1).Use 4-bit DIP switch to select 16 group ID (such as 0001, 0010, 0101 etc.)
When you set up the group ID for each transmitter just like this :
3).For example, when the devices are connection as below :
Source (DVD2) - TX (TX2) - Gigabit Switch - RX(RX2)- TV2
Source (DVD3) - TX (TX3) - Gigabit Switch - RX(RX3)- TV3
Source( DVD1) - TX (TX1) - Gigabit Switch - RX(RX1)- TV1
2).Change group ID easily to select the sources.
Howtouse DIPswitch:
TX1 (0001)
TX2 (0101)
TX3 (0100)

Setup HDMI TX and HDMI RX
A HTTP server is embedded in each TX and RX. you can setup IP address for HDMI extender via web
browser.
The default IP address of the TXis 192.168.168.55, MACaddress is: 00:0b:78:00:60:01.
The default IP address of the RX is 192.168.168.56, MAC address is:00:0b:78:00:60:02.
Step 1:→Assign the PC (or laptop) IP address on the computer : “Control Panel” ” Network
→→ →Connections” “Local Area Connections Status” “Properties” “Internet Protocol (TCP/IP)”, Type the IP
address eld with 192.168.168.11 (0-255) and Subnet mask with 255.255.255.0. After that press OK
to save the conguration.
Note: The IP address of PC should be different from the IP address of TX and RX.
Step 2: Use an Ethernet Cable to connect the PC (or laptop) and the extender. the power LED for the
extender is red and the status LED becomes green.
Step 3: → →please Ping the connected device through the sequence on computer: “Start” “Run” input
→“CMD” input “ping 192.168.168.55” for TX or input “ping 192.168.168.56” for RX, you will receive
the reply if the connection is established.
Step4: Login in the IP adress :192.168.168.55 (default IP for TX) or 192.168.168.56(default IP for RX),
You can setup IP address, subnet mask, gateway, and MAC address for the TX and RX.
Please set IP address for each TX and each RX, IP:192.168.168.XX (XX:1-255. all IP address for TX and
RX must be different .
Please set MAC address for TX and RX, MAC:00:0b:78:XX:XX-XX (XX:01-FF), The MAC address for each
TX and each RX must be different .
Step 5: After click “Apply” button, the green LED light on the device will go out, you have successfully set
IP address for TX and RX now.
Note: if you need to restore the device to it’s factory default settings, please power on the device, the red
light becomes lighting, waiting about 10 seconds, the green LED light starts working, at this time to press
the reset button about 5-10 seconds, then the green light will go out, you have successfully restored IP
address to factory IP address now.

header (eg: If you need send “5A” from RX to TX, the IP address of TX is 192.168.168.55, “CO A8 A8 37”
is the Hex format of IP address 192.168.168.55, then you should send “CO A8 A8 37”; if you need send
“5A” from TX to RX, the IP address of RX is 192.168.168.56, “CO A8 A8 38” is the Hex format of IP
address 192.168.168.56, then you should send “CO A8 A8 38”;).
