controlling an ortec trump pci multichannel buffer card using labview

[absu]

How do I send commands to an ortec trump pci multichannel buffer card using labview? I want to eventually connect an x-ray detector to the card and control it. the ortec software that came with uses activeX to control the instrument but right now I have no instrument. I just want to send commands to the card. How do I do that in labview 7?

When you say, "I just want to send commands to the card", do you mean, "I want to simulate having the instrument connected"? Or do you really want to send commands to the card itself, and not to an instrument?

If the former, then hopefully your ActiveX object has a simulation mode that can operate without the instrument connected. Check your ActiveX programming manual for this object, or ask the vendor.

If you want to communicate with the card only, then the ActiveX object probably already does this. You will be limited to only those methods and properties that pertain to the card. If the ActiveX object doesn't support this, do you have a register-level programming reference for this card? If so, you could use NI-VISA to program this card through
that interface.

If are really a glutton for punishment, you could write your own ActiveX server to simulate the instrument and/or card.

Sorry I can't be more definitive in my response; I'm just guessing based on your description.

Acutally I want to communicate to an x-ray detector that will be connected to the card. the ortec software that came with the card has some activeX controls which I use to send commands to the card and receive responses. The ultimate goal is to set data collection times, regions of interest and acquire the data through the card interfacing with the detector. Are there any example labview programs out there that you know of?
