Encoder signals from 5 VDC to 24 VDC (must specify the voltage when ordering)
This is the preferred type of encoder output as it has the best noise immunity. Connect each encoder signal to its like USB Converter
input (A to A, A/ to A/, etc).
Single Ended Line Driver
Encoder signal from 5 VDC to 24 VDC (must specify the voltage when ordering)
Connect encoder output A to optical isolator module input channel A, B to B and Z to Z. Connect the A/, B/, and Z/ inputs of the USB
Converter to circuit common of the encoder supply. Single ended operation is limited to shorter cable runs and is more susceptible to
noise.
