I have a AVT Prosilica GC660M GigE camera. It had a touble to synchonize with an external trigger. My ex-colleague posted this long time ago (http://forums.ni.com/t5/Machine-Vision/Problem-wit
I am not exactly sure why you are not seeing all the attributes, but it could be a few different things causing it. First let’s just make sure you have all you attributes being displayed (follow instructions from link below). What happens if you delete the XML file then set your camera to “External” in the GigEViewer software, then load MAX? Do you see any changes? Can you post a screenshot showing the camera attributes from MAX. If you have your camera set to External from GigEViewer and you try to grab from the camera in MAX do you get a timeout error, does it trigger external, what happens?

Hi Tim O,
I deleted .xml, .iid and .icd; set the cam to external in GigEViewr, then loaded MAX. Same thing, only "timed" option showed.
I don't have the external setup right now, I'll get back to you later. But I believe I tried what you said before, and MAX works with the external trigger even under the timed option. My inital thougt was to go ahead and edit xml file, but since I don't realy know anything about xml, that failed.
Here's the screenshot, thank you,
Did you close and reopen MAX after updating the XML file? Also, what version of Vision Acquisition and/or IMAQdx are you using?
Yes, I did. It's the same. I have Vision Acquisition Software - August 2011 and NI-IMAQdx 3.8.1.
Sure, and the work-around is to write register 14104 (RegExposureMode) with "external (enum)".
This looks like the feature is simply not implemented in their XML file:
<Enumeration Name="ExposureMode" NameSpace="Standard"> <Extension> <PvDelete/> </Extension> <Description>Method of control for exposure duration. Timed mode: exposure duration is set by ExposureTimeAbs.</Description> <EnumEntry Name="Timed" NameSpace="Standard"> <Value>1</Value> </EnumEntry> <Value>1</Value> </Enumeration>
Things to note are that there are no additional modes listed for ExposureMode besides timed and it doesn't actually redirect to a register (it has a "Value" entry rather than a "pValue" that points to a register).
It does appear that the "ExposureAuto" feature does actually redirect to that same register you are setting manually (setting it to "other" writes a 0x4 to 0x14104).
I guess this feature is working in AVT's software because their viewer does not actually use the XML file through GenICam like third-party software does.
Hi Ishi, did you get the problem resolved? I am facing the same problem right now with an AVT GT 1910.
I need to change the ExposureMode to "External" but am unable to do so in MAX.
