Installation recommendations

1. Recommended location for device installation: communications mast/pole.
2. Before you install and enable device, check the device for visible mechanical defects. If defects are observed, you should stop the device installation, draw up corresponding act and contact the supplier.
3. Install the device vertically on communications mast or pole in the way that the LAN port is pointed down.
4. In order to provide better receiving signal level, the sectoral antenna of a base station should be in line of sight of WB-2P-LR2. You may achive the highest signal level by antenna alignment with the help of RSSI indicators.
5. The transmitting part of the device is located on the other side from brackets. This area should be directed to base station sectoral antenna.

2. Enter IP address of the device to URL bar of a browser (192.168.1.1 by default, if address was not obtain via DHCP); When connection is established successfully, the window with Login and password fields will be displayed. Fill the filds and click 'Log in'. (By default, login: admin, password: password). 

...

Implement configuration on the Internet tab. In Network Mode field, select the required mode: Bridge or Router. If static settings are used for connection to a provider network, choose  «Static»  value in «Protocol» field and fill the fields: «IP address», «Netmask», «Default gateway», «Primary DNS Server», «Secondary DNS Server» – the values are given by service provider. 
Configure conection to a base station. Specify SSID of the wireless network, you want to connect to, in the corresponding field. Select security mode through which authentication in the selected wireless network is implemented and specify the key if using an encrypted network. After clicking on the 'Apply' button, the subscriber station will search for the specified SSID on the air and, upon detection, will attempt to connect to the base station with the specified parameters. If the parameters are specified correctly and the signal level is sufficient, a successful connection will occur.

Spectrum Analyzer

To use the embedded spectrum analyzer on the WB-2P-LR2, you need to login to the device via telnet or ssh. Enter the  spectrum-analyzer   command to run it. The analysis time for all the radio channels in the range is approximately 5 minutes.

System recovering after firmware update failure

...

• Unpack the archive with firmware file;
• Connect PC to the device port. Set the following subnet mask on the network interface: 192.168.1.0/24;
• Run the TFTP client on the PC (for Windows, it is recommended to use the Tftpd32), specify 192.168.1.6 as the remote host address, and select the linux.bin file from the unpacked software archive for transfer;
• Run the command to send a file to a remote host (the Put command). The process of file transmission will be launched;
• If the transmission has started, please, wait for finishing. The device will write the firmware to its memory and launch the system automatically. The time of writing takes approximately 8 minutes. If the process is completed successfully, 'Power' indicator will be green or orange. The configuration of the device before failure is saved. If you can not connect the device, reset it to factory settings;
• If the process has not started, make sure that the network settings of PC are correct and try again. If it does not work, sent the device to maintanence service or proceed recovery using the connection via COM port through a special adapter (if available);

Appendix А. Launch user script when starting the system

Sometimes you need the device to implement certain actions when starting, which cannot be implemented through settings in configuration file. In this case you may configure a user script through a configuration file that will be launched when the system starting. You may set any needed commands sequence.

...

A user script should start from the #!/bin/sh directive.
