3.1

Overview

Maintaining signal connections is one of the most important factors in ensuring that
your application system is sending and receiving data correctly. A good signal con-
nection can avoid unnecessary and costly damage to your PC and other hardware
devices. This chapter provides useful information about how to connect input and
output signals to the PCI-1751 via the I/O connector.

3.2

Switch and Jumper Settings

We designed the PCI-1751 with ease-of-use in mind. It is a "plug and play" card, i.e.
the system BIOS assigns the system resources such as base address and interrupt
automatically. There are only two functions with 11 jumpers to be set by the user. The
following section describes how to configure the card. You may want to refer to the
figure below for help in identifying card components.

Jumper Settings to Set Ports as Input or Output by Software

By shorting the upper two pins of jumpers JPA0, JPB0, JPC0L, JPC0H, JPA1, JPB1,
JPC1L or JPC1H, a user sets the corresponding ports to be configurable as input or
output ports by software. (JPA0 means jumper for port A0, JPB0 means jumper for
port B0, etc.) The initial state of each port after system power on or reset will be set
as input logic 1 (voltage high), provided that no external signals are connected, and
provided jumper JP4 does not determine otherwise (see Jumper J4 discussion
below).

Using Jumpers to Set Ports as Output Ports

By shorting the lower two pins of the jumpers JPA0, JPB0, JPC0L, JPC0H, JPA1,
JPB1, JPC1L or JPC1H, a user sets the corresponding ports to be output ports.
(JPA0 means jumper for port A0, JPB0 means jumper for port B0, etc.) Shorting the
lower two pins of a port's jumper pins disables the port from being software configu-
rable as an input port. The initial state of each of these ports after system power on or
