linkCONNECT modems are Smart modems designed to need very little knowledge to link up any equipment over the GSM network and effectively be self managing from out-of-the-box. We have many customers now using linkCONNECT modems due to their simplicity to use and connect to with existing equipment where the connected equipment does not have to change at all.

The linkCONNECT LC200 series of self managing modems makes connecting RS232 devices to the 2G or 3G networks simplicity itself.  The Siretta linkCONNECT software does all the hardwork for you and is easy to configure and work with.  When connected to your RS232 equipment the LC200 series will auto negotiate and connect to any network and reboot as necessary to maintain connectivity to the internet and / or be monitored / controlled from anywhere in the world.

The linkCONNECT LC200 series is a truly 'plug-n-play' RS232 to 3G/GPRS modem in that it requires no set up and is protocol transparent. Connect your equipment to the LC200 and any data it produces is transmitted automatically over the  cellular network to the user or server as set up. The LC200 can also be configured at any time via SMS messaging and can be operated in Client or Server mode.

linkCONNECT Client Mode 

In the Client mode LC200  acts as a client, simply connecting the terminal to a remote server at a pre-specified IP address and port. It can either be setup as ‘always connected’, or to connect only when data is received on the serial port. Once set up, the LC200 needs no further intervention to remain in full client mode. 

linkCONNECT Server Mode 

In the Server mode LC200 acts as a server, where the terminal listens for incoming connections from a remote client on a specified port. Additionally a source IP can be specified, and only connections from this IP will be accepted.
