HS-190 monochromator

[UNCKai]

I am trying to write a labview program which allows me to control the HS-190 monochromator via a remote desktop connection. I am modifying an existing code which used this function to perform some IPCE measurements but all I need to do is be able to control what wavelength of light the monochromotor outputs. I'm attaching both the original program (The Program - Angular IPCE) as well as what I have so far (monochromator). Because of my inexperience with labview, its hard for me to know exactly what is needed.

For example, the event structure "0, Timeout" within the case "False,default" is giving me a lot of trouble because I am not sure what its function is but it is apparently very necessary. Regardless of how I modify the program, it will not advance beyond this point.

Any help you can offer is most appareciated, even it its simply exaplining what this event structure is doing exactly. I've searched for instrument drivers as well for this particular monochromator but I havent been able to find anything.

Thank you

Hi UNCKai, 

   Before we get too far down the rabbit hole, I'd like to clarify some simple questions:

1.  Are you able to connect to the HS-190 at all?  I suspect that if you haven't found an instrument driver, you haven't been able to communicate with the monochromator using even the most basic signal checks.  First and foremost, you need to find an instrument driver.  Check with the manufacturer to see if they have LabVIEW drivers available.  It is possible to write drivers for your component, but it is quite a task.

2.  Does the original program code you are starting from work properly with the same hardware (HS-190?), or different hardware?  If so, what hardware?)

3.  If you are unfamiliar with general LabVIEW concepts, I would suggest taking a look at the online training courses:  http://sine.ni.com/tacs/app/fp/p/ap/ov/pg/1/sn/n5:selfpacedonline/     Depending on your service contract level, you may already be eligible for a number of courses.  If you have a .EDU email account, I believe you can access a few of the courses for free.
