trigger.tsplinkout[N].assert()
This function simulates the occurrence of the trigger and generates the corresponding trigger event.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
trigger.tsplinkout[N].assert()
N
The trigger line (1 to 3)
Details
Initiates a trigger event and does not wait for completion. The set pulse width determines how long
the trigger is asserted.
Example
tsplink.line[2].mode = tsplink.MODE_TRIGGER_OPEN_DRAIN
trigger.tsplinkout[2].assert()
Asserts trigger on trigger line 2.

trigger.tsplinkout[N].logic
This attribute defines the trigger output with output logic for a trigger line.
Type TSP-Link accessible Affected by Where saved Default value
Attribute (RW)
Yes

Configuration script
trigger.LOGIC_NEGATIVE
Usage
logicType = trigger.tsplinkout[N].logic
trigger.tsplinkout[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
The trigger line (1 to 3)
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.
