3.1 Pulse Output Signals OUT and DIR
There are 8 axis pulse output signals on the PCI-8158. For each
axis, two pairs of OUT and DIR differential signals are used to
transmit the pulse train and indicate the direction. The OUT and
DIR signals can also be programmed as CW and CCW signal
pairs. Refer to Section 4.1.1 for details of the logical characteris-
tics of the OUT and DIR signals. In this section, the electrical char-
acteristics of the OUT and DIR signals are detailed. Each signal
consists of a pair of differential signals. For example, OUT0 con-
sists of OUT0+ and OUT0- signals. The following table shows all
pulse output signals on P1.
