SC-206X Series User Manual
Chapter 1
Introduction
This chapter describes the SC-206X Series boards; lists the contents of your SC-206X Series kit;
describes the optional equipment and software support; and explains how to unpack your SC-206X
Series board.
The SC-206X Series consists of three digital signal conditioning boards (the SC-2060, SC-2061, and
SC-2062) you can use with the National Instruments data acquisition boards. The SC-2060 optically
isolated digital input board isolates digital signals received by data acquisition boards from the power
system of the host computer. The SC-2061 optically isolated digital output board isolates digital
signals sent by data acquisition boards used in systems that are isolated from the power of the host
computer. The SC-2062 electromechanical relay digital output board has eight electromechanical
relays controlled by digital output signals from the data acquisition boards. You can use the SC-206X
Series boards for digital signal conditioning on the Macintosh NuBus computers with the NB Series
and Lab-NB boards, the IBM Personal System/2 (PS/2) Micro Channel computers with the MC Series
boards, and IBM PC/XT/AT and compatible computers with the AT Series and Lab-PC+ boards.
Table 1-1 lists the data acquisition host boards that you can use with the SC-206X Series boards.

MIO-16 board refers to the AT-MIO-16F-5, AT-MIO-16, AT-MIO-16D, AT-MIO-16X,
AT-MIO-64F-5, MC-MIO-16, NB-MIO-16X, and NB-MIO-16 boards. DIO-24 board
refers to the PC-DIO-24, MC-DIO-24, and NB-DIO-24 boards. DIO-32F board refers to
the AT-DIO-32F, MC-DIO-32F, and NB-DIO-32F boards. Lab board refers to the Lab-
PC+ and Lab-NB boards. DIO-96 board refers to the PC-DIO-96 and NB-DIO-96 boards.
Each of the SC-206X Series boards connects to the host data acquisition board (MIO-16, DIO-24,
DIO-32F, DIO-96, or Lab) via a corresponding SC-205X Series cable adapter board designed for the
data acquisition board you are using. This adapter board connects the specified SC-206X Series board
to the desired 8-bit digital port of the host board. Figure 1-1 illustrates an SC-2060 board connection.
