SPECIFICATION
FAQ | | H7710 GPRS/CDMA DTU is a data termination unit based on GPRS or
CDMA 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. H7710 GPRS/CDMA DTU
provides RS-232/RS-485/RS-422/TTL interface. Embedded with PPP,
TCP/IP and DDPTM protocol, it converts the user data into GPRS or
CDMA 1x network and transmits the data into the customer’s data
service center. With the professional designing, the H7710
GPRS/CDMA DTU provides the plug and play, easy to use and
maintenance features.Hongdian products have been widely used for
many application areas in the world, such as electric power, oil
field, coal mine safety, weather forecast, environment protection,
heating pipe line, gas pipe line, street lamp control,
telecommunications, post, bank and many other areas. |
