Assigning an Input to a Trigger

This menu appears only if you answered YES to the Edit Segment
Triggers menu. Use it to assign one of the controller’s eight digital
inputs to a segment trigger. You can assign any digital input to ant
trigger. You can also assign the same digital input to multiple triggers.

Selectable Values: 1-12, or No (no input assigned). Setting a trigger to
No disables it.

Changing a Trigger’s True State

Use this menu to toggle a trigger’s true state between On and Off. This
menu appears only if you answered YES to the Edit Segment triggers
menu.

Selectable Values: Off or On.

Latching or Unlatching a Trigger

Use this menu to make a trigger latched or unlatched.

A latched trigger is checked once, at the beginning of a segment.

An unlatched trigger is checked constantly while a segment is run-

ning. If an unlatched trigger becomes false, the segment timer stops
and the loop goes into trigger wait state.

Selectable Values: N (No: unlatched), Y (Yes: latched).
