Q00217 USR-GPRS232-710 Serial RS232/RS485 to GPRS DTU Converter Support GSM Net + FreePost

Description
- 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.
