Using This Chapter

This chapter is divided into twelve sections and details how to use the Keysight
E1458A Digital I/O Module.

Port Description

Each of the digital I/O module ports has eight data lines and seven control lines.
Not all these lines are required for every application. Figure 1-1 earlier in this
manual shows the data and control lines. The following subsections describe the
use of these lines.

Data Lines

Each port has eight data lines, numbered from 0 to 7. The data lines can be set
as an 8-bit group, as part of a larger group, or individually using SCPI
commands.
The logical TRUE condition of the data lines can be controlled with SCPI
commands. Positive polarity is the default. The following table shows the effect
of changing the Polarity with Input and Output operations for each data line.
