System Configuration
Preparation to connect to Web ServerStep 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.
And then, click the properties of the Wireless Network in the “Network Connection‟ page. Open “Internet Protocol Version 4 (TCP/IPv4)” on the tap of the Networking, and then click the “Properties‟.
Set the IP address and Subnet mask as the following figure.
Please check if the wireless network is connected to Tx SSID, “QDM-3000”.
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.
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.
Configuration Rx
- The Tx and Rx should be connected properly. On the “20.20.20.2” page, please select the “Device tap” on the left, and configure as below:A. QIM Mode: RxB. Startup Mode: ClientC. Local IP Addr: 20.20.20.2 (for example)D. Local Netmask: 255.255.255.0Click the “Save‟ button after all configuration.
- Please select “Wireless” tab on the left to configure SSID name. Note that both Tx and Rx should connect to the same SSID.
- Please click the “Save‟ button after configuration of the wireless settings. Subsequently, click the “Reboot‟ button to restart the Tx and Rx, and they will be automatically paired and connected automatically.
Configuration Tx
- The Tx and Rx should be connected properly. On the “20.20.20.1” page, please select the “Device tap” on the left, and configure as below:A. QIM Mode: TxB. Startup Mode: RootAPC. Local IP Addr: 20.20.20.1 (for example)D. Local Netmask: 255.255.255.0
- To configure SSID, select “Wireless‟ tab, and then set an SSID, for example, “QDM-3000”. The Tx and Rx are connected through this SSID network. The pair of devices should connect on the same SSID network. After configuration, click the “Save” button and click the “Reboot‟ button to restart the unit.
