Hi Faustina, I have done a bit of searching on this matter and found this document that you can use to get started with the GPS synchronization using the 6683H http://www.ni.com/tutorial/53314/en/ to use this with your Ballard cards you will need to consider the following:
- Use the GPS module (6683H Timing and Sync card) to discipline backplane clock to PPS
- Accept the signal into the Ballard card
- Use XML editor (Ballard SW) to trigger accordingly.
Keep in mind that a couple of SW components are going to be needed here.
- NI-Sync
- PXI Platform Services
- Ballard LabVIEW API
- XMLEditor (Ballard SW)
If you have further questions about this feel free to reach out to support through a Service Request, you may find more resources to get assistance for this issue if needed.
