As shown in Figure 3, first bit code representation of RS485 communication baud rate in the ON position, set the baud
rate 2400, in the Off position the baud rate is 9600, the real-time adjustment.
2, 3, 4 bit code represents the RS485 address, when the shifting to the ON position are respectively corresponding to 4,
2, 1 values; All in the numerical Off position corresponding to 0. The physical meaning is dial to the corresponding
numerical 9 is the expansion board 485 communication.
2 3 4 Sensor RS485 Address
0 0 0 9
0 0 1 10
Now we only use RS485 Address 9&10
RS485 Address 9 is the CW temperature Sensor.
