2.6 Signal Connections
2.6.1 Pulse Output Signals OUT and DIR on CN2
With 4 axes pulse output signals on the PCIe-8154, each axis
uses two pairs of OUT and DIR differential signals to transmit the
pulse train and indicate the direction. The OUT and DIR signals
can also be programmed as CW and CCW signal pairs. Each sig-
nal consists of a pair of differential signals. For example, OUT0
consists of OUT0+ and OUT0- signals.
