Data transimission Industrial GPRS Gateway 2.5G DTU, serial to cellular IP

 
Industrial GPRS Gateway 2.5G DTU, serial to cellular IP for data transimission
 
Description
 
The WL-D801 GPRS serial gateway (also called DTU) can look similar to the common Modems / terminals. Wlink serial to GSM/GPRS/EDGE IP modem is a kind of cellular terminal device that provides data transfer function by by mobile 2G/2.5G network.It adopts high powered industrial 16/32 bits CPU 

and embedded real time operating system.The cellular gateway has additional processing capability and built-in software which allows them to operate autonomously as self-managing communications devices.

It supports RS232 ( or RS485, RS422) port that can conveniently and transparently connect one device 

to a cellular network, allowing you to connect to your existing serial devices with only basic configuration.
Once configured, WLINK DTU provide ‘IP’ or internet communications for other devices which have limited or no built-in capability to manage a modem.
