GSM 3G M2M
RTU S*7x is a multi I/O port remote
terminal unit, through the RS**2/**5 port can extend up
to *4 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 RJ*5 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, RS**2, RS**5, RJ*5, 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 RS**2/**5
exceeds threshold, it also can send pre-definition SMS
to users.
A: I/O
port connections, RS**2/RS**5 extend I/O ports, RS**2/RS**5
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 RJ*5 LAN cable or GPRS or 3G to OMC, the protocol
is defined by user of personal.
C:
Through RJ*5 LAN cable or GPRS or 3G or RS**2 or RS**5 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.
