Network Interface Card


DTDS Network Interface Card is a generic interface designed to act as a communication gateway between primarily an Energy Meter and a 3G GSM network. The application could also be extended to other utility meters like Water Meters etc. IPV6 SIM card makes it configurable on the fly in a Client or Server mode depending upon the need.
