1586A Users Manual Digital I/O (DIO) Channel Configuration (Ch401) The Product can sense and output a digital, 8-bit transistor-transistor logic (TTL) value that can be displayed as the 8-bit TTL value and be recorded as the decimal equivalent. This is accomplished with the rear-panel digital I/O connectors (DIO) that are shown in Figure 3-8. When a DIO input is sensed, the Product displays the status of the digital I/O as 8-bit TTL value and records the decimal equivalent. The 8-bit TTL value can also be seen when a channel is monitored. The default value is a high state that shows as "11111111" until the Product senses a low state or is used as an output. A few examples of some 8-bit TTL values and their decimal equivalents are shown below: • 11111111 is represented by decimal 255 • 00001111 is represented by decimal 15 • 00010001 is represented by decimal 17 • 10000101 is represented by decimal 133 Notes For input and output specifications such as input and output voltages, see "Digital I/O" in Chapter 1. The DIO channel will be read-only when it is set to ON (active). With a remote command, the Product can output an 8-bit TTL value. See the 1586A Remote Programmers Guide for more information.

Digital I/O (DIO) Channel Configuration (Ch401)
The Product can sense and output a digital, 8-bit transistor-transistor logic (TTL) value
that can be displayed as the 8-bit TTL value and be recorded as the decimal equivalent.
This is accomplished with the rear-panel digital I/O connectors (DIO) that are shown in
Figure 3-8.
When a DIO input is sensed, the Product displays the status of the digital I/O as 8-bit
TTL value and records the decimal equivalent. The 8-bit TTL value can also be seen
when a channel is monitored. The default value is a high state that shows as “11111111”
until the Product senses a low state or is used as an output. A few examples of
some 8-bit
TTL values and their decimal equivalents are shown below:
•
11111111 is represented by decimal 255
•
00001111 is represented by decimal 15
•
00010001 is represented by decimal 17
•
10000101 is represented by decimal 133
Notes
For input and output specifications such as input and output voltages, see
“Digital I/O” in Chapter 1.
The DIO channel will be read-only when it is set to ON (active).
With a remote command, the Product can output an 8-bit TTL value. See the
1586A Remote Programmers Guide
for more information.
