Resistor Jumper Setting
The RS485 bus needs two 120 ohm resistors, one at each end.
Set a 120 ohm resistor on each of the two devices furthest apart (keyboard or
dome) on the RS485 bus.
The default setting is OFF. When connecting the first and second pins in JP1, the
120 ohms termination resistor is connected. When connecting the second and third
pins in JP1, the termination resistor is unconnected.
