Important Note
When using Virtual I/O points to generate triggers at regular interval, as
programmed in the Visionscape
®
IO Display or the FrontRunner RunView
IO bar the accuracy of the timing between triggers will depend on the
Operating System the avp runs on and also on the number of Virtual I/O
points programmed to be triggers. The following information provide
guidelines based on Device/OS configurations:
• GigE Cameras and Software Systems — Triggers generated by the
avp, IO display and FrontRunner IO bar.
– Windows XP — Accuracy +/- 5 msec typical, trigger to trigger
time increases as more triggers are generated.
– Windows 2000 — Accuracy +/- 25 msec typical, trigger to trigger
time increases as more triggers are generated.
Note: The values above are typical and may vary from PC to PC.
Accuracy should be measured/tested first for the particular avp for the
particular PC.
When greater accuracy than the Device allows is required, physical
triggers should be used instead.
