Last modified by Lev Andronov on 2025/08/05 11:00
Detailed guide Vision Point II Migration Guide is available within Vision Point II installation package. Also you can download PDF document directly.
Principal migration statements
- 1st generation grabbers are supported only by the Vision Point (KYFGLib) up to ver 6.4.2 (Vision Point 2024.1 SP 2).
- 2nd generation grabbers are supported by both Vision Point (KYFGLib) and Vision Point II (KYVPLib)
- Since old Vision Point (KYFGLib) will not receive any further development and fixes, we encourage to use the new Vision Point II API through API adapter (KYFGLibA) for the existing applications that was build for Vision Point (KYFGLib)
- Make sure that the frame grabber has the latest firmware update installed in order to work with Vision Point II.
- 3rd generation grabbers are supported only by the Vision Point II (KYVPLib), but can also be accessible through API adapter (KYFGLibA)
Device/software compatibility
Important note:
Vision Point 1 will not receive any further updates. We advise switching your application to use the VP to VP II Adapter.
Relevant API library names:
- KYFGLib — Vision Point
- KYFGLibA — Adapter for Vision Point to Vision Point II
- KYVPLib — Vision Point II
