<{POST_SNAPBACK}>hi bruce,
one more two questions:
1) what makes the difference in the settings "number of ghost car running" , when in take 1 gost or 5.- what means this to the race? whats the difference?
2) when i have a timed race, for example 5 minutes, the result shows 19 laps in 5:21 minutes...? where comes the 21 secondes? the race ended by exact 5 minutes.
greetings
klaus
1) If you have more than one ghost car running, laps get counted every time the ghost crosses. So the 'ghost driver' can finish very quickly if he's running 3 or 4 cars. If you tell the software you're running 3 ghosts, it won't count a lap for the ghost until 3 cars have crossed. You can attempt to address this issue using the minimum lap time, but I like this solution better.
I got the idea from brumbaer- he uses it in his Mac software. And we all need to thank him for making the protocol available, or I wouldn't have been able to write the software.
2) The results can differ, but I'm not sure how they could read more than the length of the race? The time reported at the end of a heat is the time that has passed when the car last completed a lap. That will often be less than the total length of the heat. For timed races, the session
totals will display a time exactly equal to the length of the race(s), but the heat times can differ.
Carrera's digital solution doesn't really lend itself well to timed races, because the track power control is completely decoupled from the timing hardware. That is, the lap counter can't tell the Black Box when a 5 minute race is over, and the Black Box can't tell the lap counter that the power has been cut (track calls).
My next major release is going to partially address this issue- at least for me. I have a relay board hanging off the parallel port of my race track computer, and the power to the rails runs through the relay board. It will be used to cut track power. At the end of a race, and using track calls during a race (the timer will stop during the track call).
