1Product Introduction
1.1 Product Overview
The rugged D83 serial to IP modem which is a cellular modem have been developed
especially for M2M/IoT application. It provides RS232/RS-485/TTL interface and equipped
with PPP, TCP/IP and DDP protocol, it could convert the user data into 4G, NB-IoT/CATM,
3G, EDGE or GPRS network and transmits the data to the customer’s data service center
through complete transparent data channel, allows a simple and rapid integration of
cellular network connectivity into M2M/IoT application.
