GPRS Module Automatic Meter Reading System For Wireless Data Collecting RS232

GPRS Module in Automatic Meter Reading System for Wireless Data Collecting RS232

Introduction of RS232 / RS485 GSM Modems

This is a RS232/RS485 to gprs dtu, used for data transparent transmission. GPRS232-730 GPRS DTU (Data Transfer Unit) is a wireless terminal equipment which can convert serial data to IP data or convert IP data to serial data through gprs network. 730 is based on USR-GM3. Clients can use this product to realize bidirectional transparent transmission from serial port to network through simple AT command.
