USR-GPRS232-734RS485 Serial GSM Modem
USR-GPRS232-734 is a RS485 Serial GSM Modem, used for data transparent transmission.
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.
