The drive units may be affected by reflection depending on the transmission speed or transmission distance. If this reflection
hinders communication, provide a terminating resistor. If the PU connector is used to make a connection, use a distributor since a
terminating resistor cannot be fitted. Connect the terminating resistor to only the drive unit remotest from the computer.
