2. H7710 Series DTU Features

 

DTU = Data Termination Unit
DDP - DTU/DSC Protocol, it is the data transmission protocol between DTU and data service center.

H7710 GPRS/CDMA DTU provides RS-232/RS-485/RS-422/TTL interface. Embedded with PPP, TCP/IP and DDP protocol, it converts the user data into GPRS or CDMA 1x network and transmits the data into the customers data service center.


H7710 GPRS/CDMA DTU is a data termination unit based on GPRS or CDMA1x mobile network. It provides data communication network for industrial applications. With the reliable, flexible and cost-effectiveness features, it can be utilized at many areas to provide the M2M communication channels.
