3.1.3 Servo drive pulse I/O interface

OUT / DIR (pulse output control / DO signal)
Pulse output control function: PCI-M324 is built-in with six different pulse output control functions,
which are controlled by the DIR and OUT output interfaces. The hardware circuit is designed to
adopt the RS-422 differential line driver output interface, which can connect to RS-422
differential, optocoupler, and TTL unipolar interfaces.
