The SMB connector on the PCIe-1433 can be used for front panel trigger connectivity. It can be used as a 5 V input to trigger acquisitions or as a 5 V output to provide status information to your system. The default for the SMB Connector is an input. You would need to use LabVIEW to change the SMB connector to be an output. You can control the SMB line in LabVIEW by using the IMAQ Trigger VIs and referencing trigger line 0. A good starting place is the LabVIEW Vision Acquisition Shipping Examples. The examples can be found in the LabVIEW example finder at the following locations:
Hardware Input and Output >> Vision Acquisition >> NI-IMAQdx >> Hardware-Specific >> Camera Link >> IMAQdx >> Triggered Acquisition (Camera Link).vi
Hardware Input and Output >> Vision Acquisition >> NI-IMAQdx >> Hardware-Specific >> Camera Link >> IMAQdx >> IMAQdx Compatibility for IMAQ >> Compatibility TriggeredÂ
