Chapter 3
BNC-2081 Board
This chapter describes the BNC-2081 board in detail, including its function, specifications, compatibility,
connection, mounting, and application notes.
The BNC-2081 is an analog breakout board that makes it easy to connect to all Lab data acquisition
board analog signals, a few digital signals, and two user-defined connectors via BNC-type connectors.
Analog input signal conditioning can be added, such as filters and dividers. All other Lab signals can be
accessed by solder holes in the board located next to the Lab input connectors. In addition, there is a
connector to provide access to all digital I/O ports. This connector is in the standard pinout for
connection to one of National Instruments DIO-24 boards.
The BNC-2081 board is used with the National Instruments Lab data acquisition boards for the
Macintosh (Lab-NB and Lab-LC), IBM PC/XT/AT, and compatible computers (Lab-PC and
Lab-PC+).
Figure 3-1 shows the BNC-2081 board.

Figure 3-1. BNC-2081 Analog Breakout Board
The BNC-2081 board has BNC connectors for eight single-ended input channels. Open component
positions at each analog input facilitate the addition of user-selected signal conditioning. With open
component positions in the input paths, you can insert user-supplied resistors and capacitors for
conditioning the eight single-ended analog input signals.
