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

The module must be installed in such a way as to meet electrical safety requirements and prevent accidental contact of contacts under high voltage. The module must be operated under recommended environmental conditions. | |||
