Product Description

1.1.Instruction

GPRS DTU (Data Transfer unit) is a wireless terminal equipment which can converter

serial data to IP data or converter IP data to serial data, then transmit through wireless
communication network. GPRS DTU is to use GPRS network to transmit data, it adopts
industrial-grade embedded processor, embedded TCP/IP protocol stack. To provide users
with virtual private networks, which is high speed, stable and reliable, data terminal online
forever, and a variety of protocol conversion.
