Lance communication LZ7 13C GPRS DTU (data transmission unit) is embedded with TCP/IP protocol stack. Based on the existing GPRS network, remote wireless transmission of transparent data can be easily realized, which has many advantages, such as wide coverage (where mobile phones can be used), convenient and flexible networking, low operation and maintenance cost and so on. Widely used in electric power, water conservancy, environmental protection, transportation, meteorology, coal mine, petroleum and other industries. It provides RS232/422 interface, which is suitable for user equipment with RS232/422 interface.
System functions:
Transparent data transmission and protocol conversion
Support virtual data private network (APN)
Support CSD circuit data exchange mode
Support dynamic domain name and IP address access of data center.
In completely transparent mode, data can be sent to up to 5 centers at the same time.
It supports DTU sleep and can be awakened by phone, SMS and data stream, saving traffic.
With the real-time clock, online and offline can be timed as needed, saving traffic.
Short message data backup channel
Support local and online remote upgrade and maintenance.
The reliable design of various software and hardware ensures the safe operation of the equipment.
EMC anti-interference design
