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
