If the device is the last one on the RS-485 line, a 120 Ohm resistor-terminator must be installed between its inputs A and B. Practice shows that in case of bench tests with a small length of the RS-485 line and a small number of devices, terminator for the last device in the line is not necessary. | If the device is the last one on the RS-485 line, a 120 Ohm resistor-terminator must be installed between its inputs A and B.
