6.1 Preparation to connect to Web Server
Step 1. In order to configure the Tx and Rx, use a PC with wireless LAN function.
Please use PC static IP to connect the web server. Go to “Control Panel -> All Control
Panel Items -> Network and Sharing Center -> Change adapter settings” (Microsoft
Windows version) to set the Static IP of the PC.

After the network setting of the PC, please power on the Tx and Rx. After pairing both
devices, please type “20.20.20.1” in the web browser to configure the web servers to
configure Tx.

ALFATRON ALF-WL-HDMI

Please type “20.20.20.2” in the web browser to configure the web servers to configure
Rx.
※ Attention: The basic connection of the web server is through the RootAP. To
connect the client web server with a browser, the RootAP should be alive and paired
with the client. They show that Startup Mode are RootAP and Client. If you change the
SSID in the RootAP, the PC has to connect to the SSID’s AP that has changed, not the
QDM-3000’s AP.
