External Trigger via LabJack

[ursi]

The problem still remains...

def ExtTrigg():
	print 'trigger > 2.0'


###+++++++++++++++++++++++++++
def checkTrigger():		
	trigg = d.eAnalogIn(0) # AI0
	if trigg > 2.0:
		ExtTrigg()

vizact.onupdate(0, checkTrigger)

How can I address the 'right' output to be checked?
Why does it not work to feed in a voltage?

What do you get if you try the following? This should print out the voltage once a second. Do you notice any errors in Vizard's input/output window?

def checkTrigger():		
	trigg = d.eAnalogIn(0) # AI0
	print trigg['voltage']

vizact.ontimer(1, checkTrigger)
