Presents: Serial Port RS232 COM to IP GPRS GSM Mobile Converter Data Transmit Module DTU Package Contents : The EOT-GPRS-701-2 DTU (Data Transfer unit) is a wireless terminal equipment which can convert serial data to IP data or converter IP data to serial data, then transmit through GSM (Mobile phone) wireless communication network. GPRS DTU use GPRS network to transmit data, it incorporates an industrial-grade embedded processor, embedded TCP/IP protocol stack. It can provide users with virtual private networks, which is high speed, stable and reliable, data terminal online forever, along with a variety of protocol conversion. Features Easy to setup, only configure a few parameters; Using single module with embedded Protocol stack, without an external CPU results in higher stability; Supports RS232 Serial interface Industrial WAVECOM Module inside Integrated with TCP/IP protocol, and GPRS technology Support four frequency,800Mhz/900Mhz/1800Mhz/1900Mhz Supports remote parameters settings, you can change IP, port, etc. by SMS; Supports GSM/GPRS/EDGE and 2G/3G/4G card, but doesnt 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; Supports data length control, can set the length of single sending package and data pack waiting time; Supports ALWAYS ONLINE mode, and dropped reconnect; Completely transparent transmission, can take place of data transfer radio, no changes needed on your original system; Use aluminum alloy case, shielding external disturbance effectively; Matched antenna, convenient for customers to install and use inside shielded areas. Supports KEEP-live, can maintain connection if there is no heartbeat packet; Supports network connection in Max 4 Channel, can send data from serial port to different servers; Supports remote parameter configuration, can configure all parameter by sending AT command via SMS; Supports password authentication by remote configuration; Working voltage:5-12V Working current: Max1200mA Name Description GSM/GPRS Parameter: Standard:GSM/GPRS Frequency: 800Mhz,900MHz and 1800MHz,1900Mhz GPRS Multi-slot Class: Class 10 GPRS Terminal Device Class: Class B GPRS Coding Schemes: CS1 to CS4 SIM Card SIM Control: 1.8v and 3v Com port type: RS-232 Com port settings: baud range : 300-115200 data bits: 5 6 7 8 stop bits:1 1.5 2 Parity bits: NONE, EVEN, ODD, SPACE, Mark Pins RS-232: TxD, RxD, GND Ethernet TCP/IP, UDP Socket program demo available as a download Size: 108x74x35mm weight: 0.5 lbs Environmental parameters: Operating temperature: -25 to 85 °C Operating Humidity: 5 to 95% RH Power require: Input Voltage: 5 to 12 VDC Average operating current:335 to 900mA@ 5v Maximum operating current 2A@+5V DC Standby Current 80mA@+5V DC Package Contents USR-GPRS232-701-2 Main Module 12V 1A Power Adapter GPRS antennaSerial Cable Requirements : - 1.)
