Hello windman,

You may use following code for enable / disable the trigger:

public static bool SetTrigger(ICImagingControl ic, bool OnOff )

VCDSwitchProperty Trigger;
Trigger = (VCDSwitchProperty)ic.VCDPropertyItems.FindInterfa ce(VCDIDs.VCDID_TriggerMode + ":" + VCDIDs.VCDElement_Value + ":" + VCDIDs.VCDInterface_Switch);

if (Trigger != null)
Trigger.Switch = OnOff;
return true;

return false;

If this does not work too, then please let me know the used driver version and camera serial number. I assume, you have installed our WDM driver and not the Microsoft standard UVC driver.

WDM driver?
if it is not included in the IC3 installation, then no.
how do I install it?

The driver is on the CD ROM. Follow the blue colored setup and install the camera driver.
