ADLINK PCI-8164 - Manual (Page 68)

56 Signal Connections
3.13 Pulser Input Signals PA and PB (PCI-8164 only)
The PCI-8164 accepts input pulser signals through the CN3 pins
listed below. The pulses behave like an encoder. The signals gen-
erate the positioning information that guides the motor.
The CN3 PA and PB pins are directly connected to PA and PB
pins of the PCL6045. The interface circuit is shown below.
If the signal voltage of the pulser is not +5V or if the pulser is dis-
tantly placed, it is recommended that a photocoupler or a line
driver be installed in between. Note that the CN3 +5V and DGND
lines are provided from the PCI bus, and that this source is not iso-
lated.
