Starting Lights System
ZRound supports Starting Lights System. The protocol can be defined and two working modes are availables (master/slave).
Temperature and Humidity data can be sent to ZRound by using special commands to be displayed on screen.
Protocol
Slave Mode
In Slave mode, ZRound send the “START” command when the race must be started and “STOP” when the lights must be switched off.
The starting lights must send the “GO” command when the startup procedure has been completed and the race must be started.
ZRound → Device
* START = $START\n * STOP = $STOP\n
Device → ZRound
* GO = $GO\n
Master Mode
When ZRound works in master mode, it controls the countdown and when the lights are switched on/off.
ZRound → Device
* LIGHT = $LIGHT,<n>,<state>\n
where
<n> is the light to be controlled <state> 0 off, 1 on
Devices tested
* Arduino based system
