Operating Instructions
5. Installation and Configuration
5.1 Setup HDMI TX and RX
When connecting point to point, no need to configure TX and RX,
When connecting point to many, many to point and many to many, please
make sure every TX and RX has unique IP and MAC address, every TX has
unique group ID.
Our this over IP Extender has been assigned unique default MAC address for
every TX and RX, so you don’t have to set the MAC for the units.
You just need to set the IP address and Group ID following bellowing steps.
5.1.1 Setting the IP address
A). DHCP (Dynamic host configuration protocol)
If you are using a Switch that supports DHCP, please enable DHCP so that
the Switch will assign an unique IP for TX and RX, and you don’t need to
change the IP for the units manually.
B). Set the IP via web browser
If you are using a Switch that doesn’t support DHCP, please change the
default IP for TX (192.168.1.11) and RX (192.168.1.12) manually.
A HTTP server is embedded in each TX and RX. You can set up IP address
for HDMI Extender via web browser
The default IP address of the TX is 192.168.1.11, user name: admin,
password: admin
The default IP address of the RX is 192.168.1.12

Operating Instructions
Step 1: Make sure the Transmitter and PC are in the same domain.
Access the Network Setting Control Panel in Windows and locate your
Lan connection. Under Windows 7, this can be done by clicking Start >
Control Panel >Network Sharing center>Change adapter settings >
Properties >Internet Protocol Version4 (TCP/IPv4). Change the IP address fi
eld to 192.168.1.1
(0-255). After that press "OK" to save the configuration.
※The PC and TX/RX should be in the same domain.
※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 green status is
blinking.
Step 3: Login in IE: 192.168.1.11 (default IP for TX) or 192.168.1.12(default
IP for RX), You can setup IP address for the TX and RX. TX requires user
name: admin and password: admin
Please set IP address for each TX and each RX, IP: 192.168.1.XX (XX:1-255.
all IP address for TX and RX must be different and can’t be same as the PC’s
address.)
Step 4: After selecting “Use DHCP” or reset the IP Address, click “Submit”
(transmitter) or “update DHCP” (Receiver).
Step 5: Click “Reboot”.
Step 6: Restart the extender after resting the IPAddress.

Operating Instructions
5.1.2 Choose the Group ID and Baud Rate by Remote controller
(When the LED shows “00”, it’s ready to work)
①Press the button, switch to
choose the Group ID or Baud rate.
②Factory reset. Press the button for
3 seconds, the LED will flicker then
turn to “00”, you have successfully
finished the factory reset.
Choose Group ID 00-63
1). Press “+” or “–” to change to the previous or next Group ID.
2). Press the No to change Group ID. For example, if you need change to 01,
press “0”, then press“1”.
Choose the Baud Rate
Press the Button, switch to Baud Rate mode, press “+” or “–” to change the
Baud Rate.
F0 = 2400 (default)
F1 = 4800
F2 = 9600
F3 = 19200
F4 = 28800
F5 = 38400
F6 = 57600
F7 = 115200
3). How to choose the source:
For example, when the connection is:
Source (DVD1) - TX (TX1) - Gigabit Switch – RX (RX1) - TV1
Source (DVD2) - TX (TX2) - Gigabit Switch – RX (RX2) - TV2
Source (DVD3) - TX (TX3) - Gigabit Switch – RX (RX3) - TV3
The group ID of transmitters is:
TX1 (01)
TX2 (02)
TX3 (03)
If you need display Source on TV1, then just set Group ID of RX1 same as
TX1: 01(see below picture).
TX1 RX1

Operating Instructions
5.1.3 Set the group ID for TX and RX via web browser
Step 1: Make sure the Transmitter and PC are in the same domain.
(Refer to 5.1.1)
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 green status
LED is blinking.
Step 3: Power on the TX or RX with 5V 1A power supply.
Step 4: Login in IE: 192.168.1.11 (default IP for TX) or 192.168.1.12(default
IP for RX), TX requires user name: admin and password: admin.
Step5: Change the group ID at “Stream setting”, “00” means group “00” here
which can be chosen from 00 to 63.
Step 6: Click “Submit” (transmitter) or update (receiver).
※When you change the group ID on both Web browser and Remote
controller, the units will follow the latest one.
※If you change the Group ID on web browser, it can’t be shown
on the LED.
5.2 Preparing the switch
When doing point to many and many to many, it requires a switch to distribute
the sources. We suggest you use the Switch that supports IGMP and DHCP.
IGMP feature help to manage the group ID which is related to switch the
sources; DHCP allow the switch to assign an IP for TX and RX automatically,
please enable DHCP of the switch.
