This page is to collect all information about LabVIEW that is used for the SpinQuest target system.

Version

• All computers for operation and development must use version 2019 SP1.
• For learning purpose
  • You might use two computers (hp) in the NM4 counting house on which LabVIEW 2019 SP1 is available.
  • You might install the LabVIEW Community Edition (or any free version) to your own computer.  There is no critical difference in basic programming between versions.

Installation of Version 2019 SP1

UVA has a LabVIEW site license as explained in this page; https://data.library.virginia.edu/research-software/labview/ .  We have to use the "Professional" version which can be installed by faculty/staff, only where version 2019 SP1 is available.  But the procedure described in the page above did not work as of July 2023.  Below is a temporary(?) procedure.

1. Install 2022 Q3, using a saved installer that UVA provided for Kenichi on 2023-07-10.
2. Create and log in to NI, using your UVA e-mail address.
   1. Any e-mail address could be fine.
3. Launch "NI License Manager".
   1. Click "Activate Software".
   2. Select "Enter a serial number" and enter the serial number into all fields.
   3. Click "Activate".
4. Start LabVIEW 2022 Q3 for confirmation.
5. Launch "NI Package Manager" (not "VI Package Manager").
   1. Click "BROWSE PRODUCTS".
   2. Click "LabVIEW and Drivers"
   3. Select "2019 SP1" and "64-bit", and click "INSTALL".
6. Launch "NI License Manager".
   1. Activate 2019 SP1, using the same serial number.
7. Start LabVIEW 2019 SP1 for confirmation.

DQMH: Delacor Queued Message Handler

• DQMH had been used in some VIs, but is no longer used actively since it is over-complicated for our system.  Below are just old information for our record.
