3.13 Pulser Input Signals PA and PB
The PPCI7443 can accept the input signals from pulser signals through the
following pins of connector CN3. The pulser’s behavior is as an encoder.
The signals are usually used as generate the position information which
guide the motor to follow.

PA and PB pins of connector CN3 are directly connected to PA and PB pins
of PCL6045. The interface circuits are shown as follows.

If the signal voltage of pulser is not +5V or if the pulser is distantly placed, it
is recommended to put a photo coupler or line driver in between. Also, +5V
and GND power lines of CN3 are direct from the PCI bus. Please carefully
use these signals because they are not isolated.
