3.1 Pulse Output Signals OUT and DIR
There are 4 axes pulse output signals on the PCI-8174. 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 characteristics
of the OUT and DIR signals. In this section, the electrical charac-
teristics of the OUT and DIR signals are detailed. Each signal con-
sists of a pair of differential signals. For example, OUT0 consists
of OUT0+ and OUT0- signals. The following table shows all pulse
output signals on *CN1. The PCI-8174 has two pairs OUT/DIR
pins with high speed trigger OUT. The output pin can be config-
ured for pulse mode or high speed trigger out mode.
