trigger.LOGIC_POSITIVE
Usage
logicType = trigger.tsplinkout[N].logic
trigger.tsplinkout[N].logic = logicType
logicType
The trigger logic:
• trigger.LOGIC_POSITIVE
•
trigger.LOGIC_NEGATIVE
N
The trigger line (1 to 3)
Details
This attribute controls the logic that the output trigger generator uses on the given trigger line.
If the output logic is set to trigger.LOGIC_POSITIVE, the trigger generator asserts a TTL-high pulse for
output.
If the output logic is set to trigger.LOGIC_NEGATIVE, the trigger generator asserts a TTL-low pulse for
output.
The output state of the I/O line is controlled by the trigger logic, and the user-specified output state of the line is
ignored.
Example
tsplink.line[3].mode = tsplink.MODE_TRIGGER_OPEN_DRAIN
trigger.tsplinkout[3].logic = trigger.LOGIC_POSITIVE
Sets the trigger logic for
synchronization line 3 to output a
positive pulse.
