Figure 1-3. RS-485 Serial Connection

If the RS-485 network is longer than 100 meters or baud rates higher than
9600 are used, connect two 120 ohm terminating resistors between the
‘+’ and ‘–’ terminal strip ends of the instruments farthest away. Should
there be different instruments or converters, refer to the specific manuals
to determine whether it is necessary to connect the above-mentioned
resistors.
