Have any of you synchronized the MacReflex system with a kistler forceplate?
We have been experimenting with infrared LED's in hopes of using the
forceplate to trigger the diode so that it appears as an extra marker in
the field to indicate time.

However, the MacReflex cameras seem to pick up alot of reflection and our
infrared source doesn't seem very stable (even though we have confirmed
that the light is in fact on). There is also a question about how to
supply power to the LED but only trigger it when there is output from the

Any ideas, comments, or suggestions would be greatly appreciated.

Thank you
