2.2.6. SW4: Terminal Resistor Switch
 Set the terminal resistor when connecting the Driver Unit to the end of the network.
◊ Select the resistor value in accordance with the characteristic impedance of the cable.

Be sure to turn off the power of the Driver Unit when setting the terminal resistor.
