The Differential Solution

Simplify your industrial, medical, or semiconductor imaging application with BitFlow’s Neon-DIF, the easiest to use and most reliable differential frame grabber available anywhere. The Neon-DIF captures images at speeds up to the camera’s highest frame/data rate, with precision image acquisition suitable for the most demanding applications.

The Neon-DIF is designed for the OEM customer looking for the performance of the PCI Express bus, a differential interface, and one of the lowest price points in the industry. The target markets are applications where the current frame grabber is no longer available but the camera and application are still important. Another niche that this product fills is differential applications where the PC needs upgrading, but the frame grabber has a PCI interface. Motherboards with PCI slots are getting harder and harder to find. Finally, customers who want to port their application to 64-bit Windows are finding that their differential frame grabbers are not supported on newer operating systems. The Neon-DIF can handle all of these situations.

The Neon-DIF is not just for legacy situations, however. There are still a tremendous number of devices that output differential data that may not even be cameras. The Neon-DIF can acquire from just about anything and efficiently DMA the data into host memory.

Adding the Neon-DIF to your application is simple with our SDK, which supports both 32-bit and 64-bit operating systems. The SDK provides high level APIs for sophisticated buffer management and low-level direct access to the board for speedy custom control.
