The TASTEK can be found under Concentrators. It is called the Generic Collector.
It basically connects via TCP/IP on port 2260.
The Generic Collector sends the same unique ASCII ID via TCP as ID string on connection, and periodically after as a watchdog string, and requires no reply from the server. The unique ID must be at least 10 ASCII characters long.
E.g. a typical message the TASTEK sends is?'AA10'+IMEI?
If you make your own device, and it follows the above convention, you can use it as a Generic Collector as well.
