control: You can start the stimulation on a trigger from an external device, for example,
a switch. You can use the trigger input to trigger the analog output channels
that you have assigned to it. The trigger works in a similar way as when you
press the Start / Stop button. You can choose the action that will be taken when
one of the channels that are assigned to the trigger input is still active. Either
the stimulus protocols on the triggered channels are stopped or restarted; or
the trigger event is ignored. You can assign the Sync Out to the trigger input.
The default settings define that Sync Out is active when Trigger In is triggered.
Please see chapter "Trigger Settings" for more details.
