Temination
It is important to use a terminating resistor at the extreme ends of your RS-485 network.
A terminating resistor needs to be connected across the A and B conductors of the last
device at each end of the network.
If you are using Belden 9842 cable, the value for termination is 120R, 0.5 W resistor.
