Bailing Technology DTU RQ26 based on GPRS network supports PPP,TCP/IP,UDP,ICMP etc.communication protocol,and a termina equipment offers transparent wireless data tranmission for user.
Definite industral design with standard RS-232/485/TTL interface can directly connect with RTU, PLC,intelligent meter etc all kinds of PLC facilities in industrial locality. Using transparent communication mode makes non-IP system equipment connect GPRS network and Internet easily and internetizes management to the locality data without upgrating the original equipment
DTU RQ26 with safe and transparent transmission mechanism compliants with data transmission affair for users in different fields,specially used in discontinuous, accidental,frequent and little data transmission,and especially used in M2M fields and application system development.
Developed with industral informationization application,DTU has been broadly used in electric moinitor,remote automatic meter reading system,petroleum conduit monitor,industral control,environmental data collection, meteorology data collection, hydrology monitor, water conservancy monitor,earthquake monitor ,street light control,public affairs,city water supply,traffic message sending etc.industries and fields
