Function features
Functional Features
Communication method:
Gathering the device communication method uses a two -way feedback communication method with the RS485 communication method
External interface:
1) The ending equipment and terminal equipment through the power line，Use the power line broadband carrier technology to communicate with each other，You can communicate with relay equipment
2) Access terminal device uses the RS485 interface (2pin phoenix terminal) to connect to external devices，Communication Potter rate can be set according to user needs
Data transmission function:
Terminal equipment DK7101-S implements a private protocol message or standard MODBUS message from RS485 from the RS485，Then pass the feedback coupling technology to send data to the designated bureau equipment specified by the same power network through the power line; realize the data from the power line from the bureau's device and analyze it into the RS485 differential signal，Send a higher -level device through the 485 data cable
