Recovering DAQ Board channel lists from a program in LabView 2

[Chem Lab]

I am working on updating a LabView program that was written in LabView 2 or even possibly earlier. I got the conversion CD and upgraded the program so I could open it on LabView 6.1. Unfortunately, in the process of this upgrade, all information regarding the access to the lines of the board was lost. At the time it was last used, it accessed a Multifunction I/O Board for Macintosh Nu-Bus, Part Number 320174B-01 and was using a Macintosh IIci computer. I have a new DAQ board, the NI-PCI-6221 that is in a new Dell workstation, running Windows 2000 and LabView 6.1. I was wondering if there is a way to recover the channel lists that should be in the subVis. Do I need to track down a copy of LabView 2 or 1 to do so? This conversion also involved a Macintosh to PC switch, which if I understand correctly is a problem in the earlier versions of LabView? I was hoping to find the best way to recover this information, so I can properly adjust the program and configure it to my new DAQ board. Thank you.

Kathleen,
A couple important points to mention. Your board, the PCI-6221 is an M Series board which can only be programmed in NI-DAQmx. This driver software is only compatible with LabVIEW 7.0 and higher. Additionally, so much has changed since LabVIEW 2, that the information in that program would probably be irrelevant anyway. Not only were using a different data acquisition board, you were using a different API to program the board. So, most importantly, you will need at least LabVIEW 7.0. Note: There are tons of outstanding LabVIEW examples that install with the NI-DAQ driver (I'm assuming that you have at least NI-DAQ 7.3 that was shipped with your M Series board). There is probably an example program that will do something very similar to what you are trying to accomplish. Hope this helps!

I'm going a little backwards in trying to hook up the DAQ board. I didn't write the initial program that I am working with, so I am simply trying to understand what it is doing. If I knew which lines were inputed into the program, I can understand how these are accessed, and I can proceed further to configure the program appropriately and hook up the DAQ board correctly. The entire instrument this is hooked up to, was in pieces when I got to it, so I'm working with little information, and I believe knowing what each of the lines is reading from and doing in the programs will be very helpful. Thanks again.

If that is the case, then your only option might be to find the version of LabVIEW that the program was written on and open it up with that version. I would like to again point out that the way the DAQ board was accessed with the old program will be significantly different than how it will be accessed with the current API (NI-DAQmx).

Hi again, and another question. How can I get a hold of LabView 2 for a Macintosh? In addition, when I get it, how can I run it? I imagine, it will not run on a newer Macintosh. Thanks again.

Ok, so your best bet (though quite a long shot) would be to post your program here and hope that someone still has an old Mac with an old copy of LabVIEW. They could open it and maybe take screen snapshots and re-post those. Other than that, I'm not sure what else you could do.

Hello again, and thank you for all of your help thus far. I'm trying to obtain information on the access to the lines of a DAQ board in a program that was written on a Macintosh IIci in LabView 2 (The program and some of the created subVIs are attached). I was hoping someone may have access to LabView 2 and an old Macintosh that could run this. If the program opens I'd like to see snapshots of the screen for the DAQ subVIs. This would help me greatly in what I am trying to do. Thank you.
