Communication wiring
The instrument provides asynchronous half-duplex RS485 communication interface,using
MODBUS-RTU protocol,all kinds of data information can be transmitted on the communication
line,theoretically,how many large instruments can be connected at the same time on one line,Each
instrument can set its communication address(Addr),communication rate(baud) can also be selected
by setting.
It is suggested that two-core shielding line should be used to connect A and B,and the shielding
layer should be connected to the earth respectively.When wiring, the communication line should be
used to stay away from the strong electric cable or other strong electric field environment.
