Chapter 3 Signal Connections

3.1 Overview

Maintaining signal connections is one of the most important factors in

ensuring that your application system is sending and receiving data cor-

rectly. A good signal connection can avoid unnecessary and costly dam-

age to your PC and other hardware devices. This chapter provides useful

information about how to connect input and output signals to the PCI-

1711U cards via the I/O connector.

3.2 Switch and Jumper Settings

PCI-1711U cards have one switch for BoardID setting.

Figure 3.1: Connector and Switch Locations

BoardID settings are used to set a board’s unique identifier when multiple

identical cards are installed in the same system.

PCI-1711U cards have a built-in DIP switch (SW1), which is used to

define each card’s unique identifier. You can determine the unique identi-

fier in the register as shown in Table 3.1. If there are multiple identical

cards in the same chassis, the BoardID switch helps differentiate the

boards by identifying each card’s device number with the switch setting.

The BoardID switch’s unique identifier has been set to 0 at the factory.
