You must set the correct Hardware Type for the application to operate. If you set this to Keyboard then for each racer you must set the UID to the key you are going to press to register a lap for them. For the other hardware types you must define the correct COM port for the software to operate.

Accuracy is set to automatic by default. This setting defines what level of accuracy the lap counter provides for lap times. It is recommended to keep this on automatic as this will use the appropriate accuracy for your defined hardware type but you can manually define 0.01 second or 0.001 second accuracy if needed.

If you have a hardware lap counter you must select the correct COM port here for the software to operate. After selecting the correct COM port you must click the Save Connection button for the settings to be saved and for communication with the lap counter to be initialized. After saving this setting it will automatically be used.

In the event that you have a second lap counter connected to the computer you must define what COM port it uses using the Secondary COM Device Selection setting. After selecting the correct COM port click the Save Connection button to save the settings and initialize communication. The secondary lap counter will only be used for register laps, it does not work with the Edit Racers Screen. Only use this setting if you have a second lap counter attached.

A DLPIOR4 Relay Board can be used to control Start/Stop lights. The application will control the relay board, during the starting race countdown the relay board can will have Relay 4 active until 2 seconds left in the countdown, at 2 seconds it will switch Relay 4 off and Relay 3 on, at 1 second it will switch Relay 3 off and Relay 2 on and finally at the start of the race it will switch Relay 2 off and Relay 1 on. When the race time limit or lap limit is reached race Relay 1 will turn off and Relay 2 will turn on. When everyone has finished their final laps or timed out Relay 2 will turn off and Relay 4 will turn on. You can connect lights to these relays to have a start/stop light for races.

If you have this relay board attached to the computer use this setting to define what COM port it is using. After selecting the correct COM port click the Save Connection button to save the settings and initialize communication.
