HSDPA 3G RS-485 terminal DTU , Cellular Industrial Modem for fire alarm system

 

Description

 

The WL-D803 3G serial Modem (also called DTU) can look similar to the common Modems / terminals. Wlink serial to 3G IP modem is a kind of cellular terminal device that provides data transfer function by by mobile HSPDA 3G 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 RS498  (or RS422, RS-232, TTL ) 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.
