Introduction

USR-GPRS232-734 is a new GPRS device developed by USR IOT in 2016. Maturation software functions, covering mostly conventional application scenarios. Users 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 use DC power supply and terminal power supply, supporting 5.0V~36.0V wide voltage power supply. RS485 circuit using electrical isolation scheme, has anti-interference ability, suitable for strong electromagnetic interference environment, such as utility industry.

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
