MacFinish ready :
Running time:
Split time:
Arrival time:
The system will send : [STX][05Hex]00000000[CR]
Every ‘Update period’ seconds the system sends : [STX][ 00Hex]HHMMSShh[CR]
The system sends a split time record : [STX][04Hex]HHMMSShh[CR]
The system will wait for ‘Lap display time’ seconds.
The system sends the arrival time record : [STX][05Hex]HHMMSShh[CR]
Example :Update =0.1 sec and lap display = 5 sec, Start of text and Mode are not printable chars.
