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 over the network connection. Direct access to the wireless module can be enabled in the Telnet Radio Access settings in the Cellular section of the web interface of the modem. Select the Enabled and Raw options in the settings and click on the Submit to save the new settings.

Important: 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).

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). Diafaan SMS Server found the modem without any problems, the modem identifies itself as a Telit LE910-EUG 4G module.
