GPRS232-7S2

Serial UART to GPRS Module,GPRS DTU,GSM Module

SKU: GPRS232-7S2 Category:
  • Description

    GPRS232-7S2 is a gprs module with uart interface, which is to use GPRS network to transmit data.

    Realize TTL to GPRS Transmission

    GPRS DTU (Data Transfer unit) is a wireless terminal equipment which can converter serial data to IP data or converter IP data to serial data, then transmit through wireless communication network. GPRS DTU is to use GPRS network to transmit data, it adopts industrial-grade embedded processor, embedded TCP/IP protocol stack. To provide users with virtual private networks, which is high speed, stable and reliable, data terminal online forever, and a variety of protocol conversion.

    GPRS232-7S2 Evaluation Board : GPRS-7S2-EVK

    Product Features of GSM Module

    • Easy to use, only configurate few parameters;
    • Use single module, embedded Protocol stack, without external CPU,Higher stability;
    • Support TTL interface, choose before purchase;
    • Using single module embedded protocol stack, no external CPU, higher stability;
    • Embedded TCP/IP protocol stack and GPRS technology;
    • Support remote parameters settings, can change IP, port, ect. by SMS;
    • Support GSM/GPRS/EDGE and 2G/3G/4G card, but don’t support 3G/4G network
    • Support public and APN network access;
    • Can configure heartbeat pack data format, transmit interval, and keep connection with server. Can configure log pack data format and automatically establish network connection with server;
    • can set the length of single sending package and data pack waiting time;
    • Support ALWAYS ONLINE mode, and dropped reconnect;
    • Completely transparent transmission, can take place of data transfer radio, no changes needed on your original system;
    • Support KEEP-live, can maintain connection if there is no heartbeat packet;
    • Support network connection in Max 4 Channel, can send data from serial port to differnet servers;
    • Support remote parameter configuration, can configure all parameter by sending AT command via SMS;
    • Support password authentication by remote configuration;
