3.1 Pulse Output Signals OUT and DIR
There are 2-axis pulse output signals on PCI-8132. For every axis, two
pairs of OUT and DIR signals are used to send the pulse train and to
indicate the direction. The OUT and DIR signals can also be
programmed as CW and CCW signals pair, refer to section 4.1.1 for
details of the logical characteristics of the OUT and DIR signals. In this
section, the electronic characteristics of the OUT and DIR signals are
shown. Each signal consists of a pair of differential signals. For
example, the OUT2 is consisted of OUT2+ and OUT2- signals. The
following table shows all the pulse output signals on CN2.

The output of the OUT or DIR signals can be configured by jumpers as
either the differential line driver or open collector output. You can select
the output mode either by closing breaks between 1 and 2 or 2 and 3 of
jumpers J1~J4 as follows.
