| ^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 "&" | | |
