Advantages
Low double serial design: single serial port/double serial port (data/configuration separate) flexible choice
Permanent online, automatic reconnection
Low completely passthrough
Low SMS/mixed data model
Low SMS passthrough mode
Low multi-center pattern/backup mode
Low multiple configuration methods (serial port, SMS, remote)
Low support a variety of superior development kit
Low equipment in outdoor environment, wiring difficulties
Low equipment in mobile environment or the working place is not fixed
Low data patch distribution wide, high cost of wiring
Low equipment needs to independent channel to send data (such as: remote maintenance equipment manufacturers/data monitoring department)
Low to collect field data can be distributed on a global scale (so long as has the GPRS/CDMA / 3 g signal coverage)
The distance between the low data center with the patch is not subject to any restrictions
User data is directly connected to the Internet, without any transfer equipment
