GSM 3G M2M
RTU S27x 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.
-
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.
-
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.
-
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.
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.
