The Auto selection uses the CVIM2 system’s internal trigger source,
whereas the I/O selection uses one of the discrete inputs for an external
trigger source.
The internal trigger’s default trigger signal rate is 600 triggers per minute. To
change the rate, pick the
Rate per Minute field. When you do, the
“calculator pad” appears, as shown in Figure 3.34. Enter any value within a
range of 30 to 3600 by picking the appropriate digits for that value, then
picking the
button (in the calculator pad).

To select an external trigger source, you must assign the current inspection to
one of the discrete trigger inputs. Pick the
Trigger field to toggle it to “ I/O ,”
then pick the Source I/O field. When you do, the Discrete I/O Set Signal
panel appears, as shown in the example in Figure 3.35 (page 3–47).
As an example, if you want to assign inspection #1 to the “In 0” input, simply
pick the “ In 0 ” input line, and the trigger name will appear on the “ In 0 ”
line, as shown by “Toolset 1.Trigger” in Figure 3.35.
The strobe signal and the trigger NAK and ACK signals can be assigned to
discrete outputs in a similar manner. Refer to Chapter 9, Discrete I/O
Assignments, page 9–9, for more information about these signals.
