• When driver run out of fuel automatically reduce his  max speed to force him to refuel
• When driver end his race automatically reduce  his max speed to avoid accident on the finish line...
• Manual and  automatic Track call

How configure Pc Lap Counter for the Slot.it oXigen:

• In the options windows select the detector ‘Slot.it oXigen’ (or ‘Slot.it oXigen V4’ for the blue dongle v4) and click on the “setup...” button
• The Slot.it oXigen interface Pc Lap Counter automatically detect the COM port to use but you can change it if necessary
• After you only need to set drivers on good lane when you set a race (lane 1 correspond at car 1, lane 2 correspond at car 2....).
• REM:at least one controller  must be powered ON, otherwise Pc Lap Counter will not be able to connect to the dongle.

Advanced options for Slot.it oXigen:

• Track call will:
  Since the controller firmware 2.14 and Pc Lap Counter 5.27 driver can ask a “track call” by pushing the “hand  brake” button of his controller during 1 sec (only for driver who have “Track call enabled” in the driver setting window).
  When a driver ask a “track call”  you can specify if  all cars will stop or if it will start pace car/Yellow flag and slow down the cars, you can also give a stop & go penalty to the driver who ask the “track call”.
  During the “track call” the  refueling of all cars can be stopped or not.
  There is some situation where driver can not ask a track call: when the car is in the pit lane, when the track power is OFF and during the  race start countdown.
  You can also setup Pc Lap Counter to automatically generate track call when a car leave the track.
  Here is a video showing the manual and automatic trackcall feature on a Slot.it oXigen track:

• Impact of the fuel on max power:
  A car with 100L of fuel will not have the same performance than a car with 20L of fuel, so here you specify the impact percentage of the fuel on the car performance.
  For example if you specify a fuel impact of 20% it mean that a car with 100L  will have 80% of his max performance and a car with 40L will have 92% of his max performance.
  The fuel impact option have no influence on “pacer” driver as there is no fuel management for “pacer” driver.
  If you don’t want to set the car performance against the fuel level then set the fuel impact option to 0 %.
• Out of fuel max speed:
  When a driver run out of fuel you can reduce his car max speed to force him to refuel
• Pace car / yellow flag max speed:   See pace car explanation here
• Pit lane max speed:
  When a driver enter into the pit lane Pc Lap Counter will automatically reduce his car speed to this value
• Driver race end max speed:
  When a driver end his race Pc Lap Counter will  automatically reduce his car speed to this value, a value of zero will stop his car.

- For each driver you can specify the maximum power and other preferences:

• Track call enabled:
  Here you specify if the driver can initiate a track call or not.
• Max power :
  This will limit the driver car top speed, for example for kids you can set it to 75%
• Brake Strength:
  Here you can specify the brake strength , “slow” will brake the car slowly  and “hard” will brake the car quickly.

Automatic track call:

Since the controller firmware 2.14 and Pc Lap Counter 5.27: during a race if the car of a driver with “track call enabled”  is not on the track it will automatically generate a track call for the driver, when the car come back and the driver push the “hand brake” button of his controller during 1 sec  it will cancel the track call.

Lap Counting in pitlane:

Since the controller firmware 2.17 and Pc Lap Counter 5.30 you can select the lap counting method in the pit lane:
count lap at the pit lane entry, at the pit lane exit or do nothing (do not count a lap).

Show Controllers data:

In the oXigen interface of Pc Lap Counter tick “show Cars/Controllers data” and it will display all information’s about controllers and cars like controller version, cars version, throttle level, low battery level, etc...
this window is always displayed on top of all other open windows so you can monitor the controller/car  data’s during the race

Green line mean that the car is on the track, orange line mean car is not on the track.
