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
