  • Page 5: Quick Start

    1. Quick Start This chapter aims at getting start USR-G760c quickly. It’s recommended that user read this chapter systemically and operate it according to instruction to make a scientific knowledge. Following chapter will introduce specific details and instruction, user can read interested chapter according to need.
  • Page 6: Product Overview

    2. Product Overview 2.1. Brief Introduction USR-G760c is a 3G DTU which is apply to CDMA2000 network type, and supports CDMA2000 1xEV-DO Revision 0 and A high speed access. With “Transparent transmission” as core function and highly usability, user can integrate it to system, to realize data transmission based on CDMA2000 2.2.

    Below is the same. Setup by AT commands 1. Set work mode to be SMS transmit mode: AT+WKMOD=SMS 2. Set destination phone number: AT+DSTNUM=15866668888 3. Set filter SMS source phone number: AT+SMSFLT=ON Jinan USR IOT Technology Limited / 37 www.usriot.com...
  • Page 10: Network Transparent Transmission Mode

    USR-G760c support 2 socket connections online at the same time: socket A and socket B, they are independent. This DTU only support working at TCP Client and UDP Client.
  • Page 11: Httpd Client Mode

    Some applications need the serial device to request data from HTTP server. But these places with serial devices, maybe not convenient to access the Internet through a router. If there exist BS SIGNAL, we can build a bridge for serial device and HTTP server with USR-G760c. Setup by AT command 1.
  • Page 12: Uart Frame Mechanism

    3.3.1. Time Frame When USR-G760c receive data from UART, it will keep checking the time interval of two adjacent bytes. If the time interval is greater than or equal to a “time threshold”, the frame is finished. Or the module will keep receiving data until data is greater than or equal to 1K, then send this frame to network by TCP or UDP packet.
  • Page 13: Length Frame

    3.3.2. Length Frame When USR-G760c receive data from UART, it will keep checking the received number of bytes. If the number of bytes is greater than or equal to a “length threshold”, the frame is finished. Then module will send this frame to network by TCP or UDP packet.
  • Page 14: Heartbeat Packet

    In the application of server sending fixed query command to device, to reduce the traffic, user can choose to send heartbeat packet(query command) to serial device instead of send query command from the server. 3.4.4.
