Source I/O –– When “ I/O ” is selected as the (external) trigger source,
this selects the discrete input in the Discrete I/O Edit panel.
•
Strobe I/O –– When a strobe light is to be used, this selects the discrete
output for the strobe trigger.
•
Ack I/O –– For applications requiring the trigger ACK signal, this selects
a discrete output for the signal.

NOTE 1: The trigger source and signal assignments can be applied only to
cameras 1, 2, and/or 3, or cameras 4, 5, and/or 6. This is shown in
Figure 3.32. Camera #1 is selected initially by default.

NOTE 2: When camera 4, 5, or 6 is used, an external +24VDC power
supply must be used, as described in Chapter 1, Hardware Connection and
Powerup Check, of this manual, and the Allen–Bradley Pyramid Integrator
Installation Manual, Publication 5000–6.2.10, which is supplied with the
Pyramid Integrator chassis.
The trigger selection field in the Toolset Trigger panel, shown in
Figure 3.33, offers two choices of trigger operation based on an internal
source (
Auto ) or an external source ( I/O ). Figure 3.33 shows that Auto is
currently selected. To “toggle” to I/O , pick the Trigge r field. To toggle back
to Auto , pick the field again.
