EIC-CG16 GPRS wireless data transmission (DTU) is a GPRS network communications platform, provides a standard RS-232/485 / TTL interface design in accordance with industry standards, can be directly with the RTU, PLC, intelligent instruments, and other single-chip controller lower machine equipment industrial site connections. Allows industrial use RS232 / RS485 serial communication port equipment immediately converted to GPRS wireless network bidirectional data transmission equipment. EIC-CG16 GPRS wireless data transmission (DTU) The use of transparent transmission mode, the user need not know the intricacies of GPRS communication theory and TCP / UDP protocol, the program can be achieved without changing the existing serial devices connected to a wireless network, saving you valuable time and existing investments, can be used for long-distance communication or control. Widely used in building automation and control, parking facilities, traffic control, LED screen control, factories, workshops, mines, banks, electrical and other remote areas. You can quickly achieve serial device remote control. l Support RS232 three-wire standard or standard nine lines, serial data rate up to 230400bps; l serial protection circuit, the maximum internal circuit protection devices; l automatic redial dropped mechanism (using the industry's only state machine algorithm); l Supports static IP or Domain connect remote host; l lightning protection design; l support multi-center end (up to 4 centers), to do data backup; l a variety of operating modes (transparent and non-transparent); l equipment is always online; l hardware Multiple watchdog mechanism; l embedded in a complete PPP, TCP / IP protocol stack; l protocol extensions; l Built PPP heartbeat mechanism to prevent the base station DTU dormant; l application layer heartbeat mechanism to maintain a stable connection application layer, timely detection connection status; l serial data acquisition, real-time data transmissions to ensure, monitor the connection status, ensure that the equipment online; l DTU command control, command inquiry by the control device communication; l upgradeable firmware; l embedded processor supports high-speed and a lot of data processing protocol; l equipment on interconnection success rate 100%; l Stability: 365 × 24 hours; automatic networking success rate after l equipment off net 100%; l in UDP transmission mode, the higher the transmission frequency (per Under 5s sends a data packet 256B), the loss rate of 3% or less; l external power supply frequent power outages, network 100% success rate, networking time in the 40s ~ 70s; l voice and data switching function (optional ); l Support local data activation (optional); l Hardware restore factory: first press and hold the FN key, plus electricity, for about five seconds POW flashing rapidly, release the FN key, again press the FN key until NET lights and LINK light flashes at the same time, release the FN key, to re-power equipment; l Power supply: standard + 5V, customizable wide voltage + 5V-36V; l power: standby 140 ~ 160mA; access state 220 ~ 260mA; transmission state 260 ~ 280mA; l Working temperature: -40 ℃ ~ + 85 ℃; l Protection class: IP53; l Patent No: ZL 2007 2 0149247.5.
