Pulse Output Signals CW and CCW

There are 4 axis pulse output signals on the PCI-8144. For each
axis, two pairs of CW and CCW signals are used to transmit the
pulse train and to indicate the direction. In this section, the electri-
cal characteristics of the CW and CCW signals are detailed. Each
signal consists of a pair of differential signals. For example, CW2
consists of CW2+ and CW2- signals. The following table shows all
pulse output signals on CN1.
