    KB3031-K Introduction
           KB3031-K embedded GPRS DTU (Data Terminal Unit) wireless data transmission terminal is a device specially used to transmit serial data through GPRS mobile data network, which is suitable for the center to transmit multi-point and multi-point scattered small and medium data volume.
           KB3031-K GPRS DTU is specially designed for industrial integration. It adopts special design in the use of temperature range, vibration, electromagnetic compatibility and interface diversity, etc., and it is stable in harsh environments.
           Based on GPRS network development, the data transmission communication range is wide, the transmission is stable and reliable. KB3031-K GPRS DTU has been widely used in unattended, remote equipment monitoring, remote data collection, remote meter reading and remote scheduling.
           For the application of power system automation, industrial monitoring, traffic management, meteorology, environmental protection, pipeline network monitoring, finance, securities and other industries, taking into account the networking needs of various application departments, it supports virtual data private networks.




    KB3031-K Features
    ► Standard industrial grade products, EMC anti-interference design, strong adaptability to environment, embedded design, lower cost;
    ►Built-in Watchdog chip, providing multiple reset mechanisms, which can be controlled by software to realize perfect industrial guarantee mechanism;
    ►Support wireless remote upgrade, can upgrade DTU program through FTP via server;
    ►Operating frequency is 850/900/1800 / 1900MHz, quad-band can be applied to all countries in the world;
    ►Advanced and strict data communication protocol, with error correction and encryption, data transmission never loses packets;
    ►Powerful, supports three working modes: DTU (system default), SMS MODEM and MODEM, GPRS data transmission mode in DTU mode, can send serial data (RS232 / RS485 or TTL) of user equipment to a server in the Internet , In the DTU mode, you can also receive SMS text messages (you need to switch to SMS through the IO port when sending text messages); SMS Modem work mode is SMS transmission terminal mode, the user can be set to type A (with protocol) and type B (transparent) SMS transmission; when used in Modem mode, it is compatible with standard AT commands (GSM07.05 and 07.07), users can write the AT command set software to complete the required functions;
    ►Support multiple ways of automatic networking: can be connected with serial port-network conversion product KB2000, KB3031-K can also be networked with the same type of product as KB3031-K (convenient to use GPRS without Internet), one-to-one One-to-many networking;
    ►Plug and play function: When networking with our own KB2000 or KB3031-K, we can build a large SCADA system without any software and hardware development at this time;
    ►IP automatic registration mechanism can realize multiple service modes and build a complete ultra-large-scale wireless application system;
    ►Remote sleep and wake up: You can use the specified number of mobile phones to dial the DTU number to sleep and wake up the DTU, which is convenient for users to sleep when not using the DTU, which greatly saves data charges;
    ►IO switch value function: It has two switch inputs and two switch outputs. You can control the binary input or query the status of the binary input through gprs network or SMS. You can open the alarm remotely and set the input alarm mode: GPRS alarm and SMS alarm, and you can set the alarm status threshold (for low-level alarm or high-level alarm), in addition, users can also customize the content of the alarm information;
    ►Powerful communication backup function: If the backup service function is turned on, the connection between the main server and the backup server can be automatically switched, and if there is a problem with the main server, it is automatically connected to the backup server;
    ►Powerful server software support, server software application for many years, powerful, mature and perfect;
