If the RS485 network exceeds 100 metres in length or baud-rate is higher than 9600, two

terminating resistors are needed at the ends of the network. Two 120 ohm resistors are

to be connected, between the “+” and “–“ terminals of the line on terminal strip of the

instrument furthest away in the network. If should be there different instruments or
converters, refer to the specific manuals to determine whether it is necessary to connect

the above-mentioned resistors.
