trigger.digout[N].logic
This attribute sets the output logic of the trigger event generator to positive or negative for the specified line.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW) Yes Restore configuration

Usage
logicType = trigger.digout[ N ].logic
trigger.digout[ N ].logic = logicType
logicType The output logic of the trigger generator:
•
Assert a TTL-high pulse for output:
trigger.LOGIC_POSITIVE
•
Assert a TTL-low pulse for output:
trigger.LOGIC_NEGATIVE
N
Digital I/O trigger line (1 to 6)
Details
This attribute controls the logic that the output trigger generator uses on the given trigger line.
The output state of the digital I/O line is controlled by the trigger logic, and the user-specified output
state of the line is ignored.
Example
digio.line[4].mode = digio.MODE_TRIGGER_OUT
trigger.digout[4].logic = trigger.LOGIC_NEGATIVE
Sets line 4 mode to be a trigger output
and sets the output logic of the trigger
event generator to negative (asserts a
low pulse).
