as the base time plus a channel time multiplied by the number of D/A channels

(

N) being used by the xPC Target application.

Digital I/O — Number of digital I/O lines on the board.

Digital I/O Latency — Latency is the time, in microseconds, between initiating

a request for data and the beginning of the actual data transfer. It is calculated

as the base time plus a channel time multiplied by the number of digital I/O

lines (

N) being used by the xPC Target application.

Example 2

1 To obtain a list of the I/O boards with at least 4 A/D channels, at least 2 D/A

channels, and no digital I/O lines, select:

Analog Input: 4

- Analog Output: 2

- Digital I/O: None

2 Leave the other parameters at View All.

3 Press the Find button.

The interactive selection guide returns output like the following:

Example 3

1 To obtain a list of the PCI D/A boards with at least 4 channels and no digital

I/O lines, select:

Bus Type: PCI

- Analog Input: None

- Analog Output: 4

- Digital I/O: None
