Setting up the MultiTech rCell modem

The Multitech rCell modems is a wireless LAN router and not just a basic wireless modem. When it is used as an SMS modem for Diafaan SMS Server, the router functionality must be disabled so that Diafaan SMS Server has direct access to the wireless module through the LAN connection.

Step 1, access the web interface
By default, the Multitech rCell router was set to fixed IP address The settings are accessible with a browser on web address When accessed for the first time, the router asks for a new login name and password. It also starts a setup wizard, the default settings are OK and I could close the wizard without changes. To be able to access the router from our LAN network, I had to change the IP number to in the Network Interfaces settings under Setup.

Direct access to the wireless module of the router can be enabled in the Telnet Radio Access settings in the Cellular section of the web interface of the modem. Multitech has hidden the Telnet Radio Access option for this modem in firmware versions 5.0.0 and higher for security reasons. The option is still available, just type the address directly in the address bar: (change to the actual IP number of the modem).

Select only the Enabled and Raw options in the settings, change the Telnet TCP KeepAlive values to resp: '10', '1' and '1' and click on the Submit to save the new settings.

Step 4, add the modem to Diafaan SMS Server
To add the modem to Diafaan SMS Server, add a new GSM Modem Gateway and select TCP/IP as the modem, provide the IP number of the rCell router and the port number for the Telnet Radio Access (the default is port number 5000).
