If the external controller does not have an internal terminating resistor
R1, R2 and R3 must be mounted within 3 ft [1 m] of the external controller. A
120 ohm resistor is recommended for high frequency encoders (over 250 kHz)
or cables longer than 25 feet. If encoder signals are multi-dropped, termination
resistors are required only at the last drop point. Do not terminate at more than
one point. Note:
