VeriLynx
VeriLynx is a built-in FinishLynx profile. This profile is customized to support the use of IdentiLynx cameras for video verification of field events, such as the verification of take-off fouls in the long or triple jump events.

- Using FinishLynx 12.0 or later:
-
Go to File | Options...
-
Select VeriLynx from the Profile: list.
- Restart FinishLynx.

- To install IdentiLynx cameras for use with VeriLynx:
- Connect IdentiLynx cameras to the FinishLynx PC.
- Align one IdentiLynx camera in the plane of the take-off board, making sure the entire width of the board is in the field of view. This camera will be used to judge take-off failures.
- (optional) Position a second IdentiLynx camera beyond the take-off board and pointed back toward the runway. This camera will be used for visual confirmation of the current athlete.

- Go to File | Options... | Database and set the Input Directory to the location of the Lynx database files (fldlynx.sch, lynx.evt, lynx.ppl).
- Select a new event from the schedule with start list or create a new (blank) event.
- Enable capture by clicking the capture icon (Event | Toggle Capture Alt-T).
- Use the TAB key to enable the Scroll New Image function.
- When an athlete jumps, hit the TAB key to disable Scroll New Image and freeze the view close to the frame showing the attempt.
- After each attempt, advance to the image frame showing the attempt, enter the athlete's bib number and hit Enter.
This will add a line label, time of day (ToD) timestamp the current frame, export a JPEG and count up the attempt number (starts at 0).
To easily go back to any athlete’s recorded jump, select the athlete in the Results Zone (or Shift-ArrowUp/Dn) and go to Results | Previous/Next Attempt (or Shift-ArrowLeft/Right) to cycle through each attempt.
- Repeat for all athletes and all attempts in the flight.
