3.1 Pulse Output Signals OUT and DIR
There are 2 axis pulse output signals on the PCI-8102. For each
axis, two pairs of OUT and DIR signals are used to transmit the
pulse train and to indicate the direction. The OUT and DIR signals
can also be programmed as CW and CCW signal pairs. Refer to
section 4.1 for details of the logical characteristics of the OUT and
DIR signals. In this section, the electrical characteristics of the
OUT and DIR signals are detailed. Each signal consists of a pair
of differential signals. For example, OUT0 consists of OUT0+ and
OUT0- signals. The following table shows all pulse output signals
on P1.
The output of the OUT or DIR signals can be configured by jump-
ers as either differential line drivers or open collector output. Users
can select the output mode either by closing breaks between 1
and 2 or 2 and 3 of jumpers J8-J11 as follows:
The default setting of OUT and DIR is set to differential line driver
mode.
P1 Pin No. Signal Name Description Axis #

4 OUT0- Pulse signals (-) 1
5 DIR0+ Direction signal (+) 1
6 DIR0- Direction signal (-) 1
37 OUT1+ Pulse signals (+) 2
38 OUT1- Pulse signals (-) 2
39 DIR1+ Direction signal (+) 2
40 DIR1- Direction signal (-) 2
