Triggering Problems
No Trigger is Received
If you are not receiving a trigger, verify the following:
• The trigger is wired to the TrigIn+/IsoIn(0)+ and TrigIn–/IsoIn(0)–
signals.
• If TrigIn/IsoIn(0) and IsoIn(1) are both being used, that the devices
they are connected to are either both sinking (NPN) or both sourcing
(PNP).
• The trigger is connected correctly based on the type of sensor it
is—sourcing or sinking. Refer to the Isolated Inputs section of
Chapter 2, Power and I/O, for information about connecting isolated
inputs.
• The sensor power supply is of appropriate voltage for interfacing to
NI Smart Camera isolated inputs. Refer to the Isolated Inputs section
of Chapter 2, Power and I/O, for information about isolated inputs.
