Introduction

USR-GPRS232-734 is a new GPRS GSM modem developed by USR IOT. Maturation software functions, covering mostly conventional application scenarios. It can realize Serial to Network bidirectional transparent data transmission via simple configuration. Supporting custom registration package, heart beat package. Supporting 2 Socket Connection, and USR cloud join in. 

USR-GPRS232-734  is a cellular modem with RS485 interface. It can transmit between RS485 port and cellular network by a SIM card. Easily to add network connectivity to serial devices in the field.

Features

  • Support:GSM850/900,DCS1800/1900,able to be used around the world
  • Support GSM/GPRS/EDGE and 2G/3G/4G card, but don’t support 3G/4G network
  • Each connection support 4KB data cache, when in abnormal connection choosing data cache to avoid data lost
  • Support sending registration package and heartbeat package data
  • Support remote configuration via SMS
  • Support multi work modes: SMS transmission mode, network transmission mode and HTTPD mode
  • Support basic instruction set and extension instruction set
  • Support establishing, maintaining and closing network connection by using extension instruction set, more flexibility in application
  • Support sending Chinese/English SMS via simple instructions, avoiding PDU sending Chinese SMS which complex and hard use
  • Support class RFC2217,can modify module serial parameter via network dynamically
  • Support wide voltage 5~36V power supply, using DC power supply and terminal power supply
  • RS485 circuit using electrical isolation scheme, has anti-interference ability

Application

GPRS GSM Modem (Data Transfer unit) is a wireless terminal equipment which can converter serial data to TCPIP data or convert IP data to serial data, then transmit through wireless network.
