-^Port settings | 19200,8,N,1|
-^Definitions | All commands start with symbol %%“%” and has a “&”%% symbol at the end \\ Transponder number is a two digits hexadecimal code (00 to FF) \\ Time uses hexadecimal notation and it is expressed in milliseconds |
-^Sender^Command^Code^Description|
-^ZRound|Startup|%**C**&|ZRound tries to initialize the connection. It is used to verify the decoder is ready. The decoder must answer with an ACK within 500ms otherwise a timeout is fired and connection is discarded |
-^Ricino|Startup ACK|%**A**&|Acknowledge the %C& startup command within 500ms |
-^ZRound|Race start|%**I**&|ZRound ask to start the race (clock must be set to zero) |
-^ZRound|Race stopped|%**F**&|ZRound ask the bridge for stopping the race. No further detection should be sent |
-^Ricino|Clock|%**T**hhhhhh&|Clock signal used for sync PC and Decoder clocks. hhhhhh is time in milliseconds hexadecimal coded. Variable code length is allowed. All numbers from T to & is assumed to be the time info |
-^Ricino|Lap|%**L**TX[,]hhhhhh&|Lap detected \\ **TX**=transponder number in hexadecimal \\  * Two digits if "," si ommited \\  * Variable digit length if used "," as separator symbol \\ **hhhhhh**=race time in milliseconds (hexadecimal). \\ Variable time length is valid, time info is coded after TX and before the finish symbol "&" |
