App For Programmable the  GPRS Telemetry Terminal, King Pigeon S272, 3G GPRS Telemetry Terminal:



Product details:

The GSM 3G M2M RTU is a multi I/O port remote terminal unit, through the RS232/485 port can extend up to 64 additional I/O or connect intelligent meters or PLC. It is special for BTS monitoring, remote data acquisition, telemetrically, BTS access control and other applications. It supports voice communication, SMS, GPRS, 3G and RJ45 LAN IP communications.



The GSM 3G M2M RTU can be used as remote access control; the authorized users can open the gate or turn on the machine with a free charge call at specified time.




The GSM 3G M2M RTU supports Modbus RTU, Modbus TCP, TCP/UDP protocol, transparent data transmission over GPRS/3G, RS232, RS485, RJ45, performs as Modbus Master or Modbus Slave.



The GSM 3G M2M RTU can be used as Modbus RTU SMS Alarm, when the data acquisition from via RS232/485 exceeds threshold, it also can send pre-definition SMS to users.


The GSM SMS Controller  3G M2M RTU  suitable for below applications:








A: I/O port connections, RS232/RS485 extend I/O ports, RS232/RS485 connect Air-Conditioners, Diesel Generator, Power System, and Battery Groups via transparent protocol or Modbus RTU protocol. Under this condition, the RTU performs Modbus RTU Master;

B: Through RJ45 LAN cable or GPRS or 3G to OMC, the protocol is defined by user of personal.

C: Through RJ45 LAN cable or GPRS or 3G or RS232 or RS485 to standard SCADA systems. Under this condition, the RTU performs Modbus Slave.



D: Through SMS to control RTU or receive alarm information, or through voice communication to open the door or receive alarm calling.
