The USB port serves to save the detection files on a USB stick. This can be done either after the race or live during the race. When plugging in a USB stick, the decoder will show a message that a stick has been detected and will copy all existing passing files to the stick. A separate folder named by the decoder ID will be created on it.

If a USB stick is plugged in during the race, the system will save the new detections every few seconds on the stick. This can serve as an additional backup: theoretically, even if the decoder had burnt down, the passing data is still stored on the USB stick which can be pulled out.

Please do not remove the stick while the system is in Timing Mode. This may destroy the file system on the stick.

For the data format of the passing files, please refer to Data File Format.
