The serial port runs at 9600 baud, 8 data bits, no parity, 1 stop bit.
No input is expected or checked for.
Each output line follows the format <TYPE>: <MESSAGE>.
Denotes that the unit is setup and ready for use, lists the configuration of the unit in a space delimited list of <DESCRIPTION>:<VALUE> fields.
An error condition has occurred, see the message for more details. e.g. if something is in the tunnel on start up
Mainly for debugging, the message cycles between:
- Waiting for train.
- Timing train.
- Calculating.
Additionally when a test mode is used you'll get something like "Testing triggers.".
A list of the configured, measured and calculated data, it's space delimited and units are included, in order the fields are:
- scale (e.g. 1:148)
- distance of the first section (millimetres)
- distance of the second section (millimetres)
- total time (milliseconds)
- time taken in first section (milliseconds)
- time taken in second section (milliseconds)
- velocity over whole distance (meters per second)
- velocity over first section (meters per second)
- velocity over second section (meters per second)
- acceleration (meters per second per second)
- scale velocity (kilometres per hour)
- scale acceleration (kilometres per hour per second)
- scale velocity (miles per hour)
- scale acceleration (miles per hour per second)
Where first and second are determined by the order the train triggered them not their order on the track.
