Caimore  CM8250P/CM8250EP  TD-SCDMA  3G
DTU  is  industrial  wireless  data  transmission
equipment; it provides users with transparent TCP
remote  wireless  data  transmission  or  transparent
UDP  wireless  remote  data  transmission  through
TD-SCDMA  3G  network.  The  equipment  adopts
high-powered ARM9 processor and embedded with
real-time  operating  system  as  software  support
platform. Large memory, built-in TCP / IP protocol
stack with Intellectual property rights. 
 
CM8250P  provides  serial  port  RS232  interface,and  CM8250EP  provides  RS485
interfaces and serial port RS232 interface and RS422 interfaces and TTL interface.
The device can direct connect clients' serial RS232/RS485/TTL devices; the device
supports dual data center backup, and supports the function of synchronous data
receiving  from  multiple  data  center;  the  device  provides  on-line  maintenance  to
maintain terminals always on-line, keep the data link smooth at any time, to achieve
high-speed, stable and reliable TCP / UDP transparent data transmission. To those
sensitive customers in network traffic and power consumption, the product supports
voice, SMS, data on-line trigger and automatic disconnection function while time-out,
as to reduce the flow and to reduce power consumption.
 
The product has an ARM9 processor and intelligent three-level industrial protection, it
not only passed 3000V electric shock test, also has a patented technology, product
performances stable and reliable.
 
This product has been widely used in power meter reading, water meters reading,
heating network monitoring, gas monitoring, water monitoring, environmental testing,
meteorological monitoring, seismic monitoring, traffic control, etc.
