Ordering the modem

The ConiuGo LAN modem is sold without antenna and power supply but a pleasant surprise for this model is that it has an SMA antenna connection instead of the MMCX connection that I saw on other modems from ConiuGo. Antenna's with SMA connections are much more common and easier to procure.

Setting up the ConiuGo LAN modem

The ConiuGo LAN modem was shipped with fixed IP number, since our LAN network uses another subnet range, the modem had to be connected to a LAN with subnet 192.168.1 to be able to change the IP number in the web interface of the modem.

Important: In the 'Connection' settings of the ConiuGo LAN modem, the 'Telnet Com Port Cntrl' property must be set to 'Disable'. If this property is set to 'Enable', Diafaan SMS Server won't be able to communicate with the modem.

The AT command set of the modem is available on TCP/IP port 10001. The CD that was supplied with the modem contains a virtual COM port driver for the modem but since Diafaan SMS Server can use the IP connection of the modem directly, it is not necessary to install it. The modem was detected without problems by Diafaan SMS Server, it identified itself as a Telit LE910-EUG modem module.

In the web interface of the ConiuGo LAN modem it is possible to change the settings for the serial port, modem and network. The web interface is easy to use and for use with Diafaan SMS Server all options except the IP number and the 'Telnet Com Port Cntrl' property can be left on the default values. If the settings are changed, you can use the 'Apply Defaults' option to set the modem back to the factory settings.

Daily operation

The ConiuGo LAN modem performed well in our tests, all SMS features are supported including USSD and delivery reports for sent SMS messages. During the test the modem did not log on to the 4G network, all the tests reflect the 3G performance of the modem.

The modem supports the full reboot command from Diafaan SMS Server after GSM modem encounters a problem. It also recovers well after the network connection has temporarily been down, this makes the ConiuGo LAN modem a reliable SMS modem for Diafaan SMS Server.

The ConiuGo LAN modem is an excellent GSM modem for use in industrial environments and LAN networks. ConiuGo modems are relatively expensive but the LAN module makes it a very useful GSM modem in combination with Diafaan SMS Server, specially in situations where a serial port- or USB GSM modem is impractical, for instance when Diafaan SMS Server is installed on a virtual computer. The support for GSM, 3G and 4G makes this modem very versatile and future proof.
