What is the VBOX serial protocol on the VBOXII?
115200 Baud, no parity, 8 data bits, 1 stop bit Message format : $VBOXII,nnnn0000,stttaaaaoooovvhheeezzmmmggcc The $VBOXII and commas are in ASCII, the rest is in binary. The first four bytes of the reserved nnnn0000 bytes indicate the presence of the channels in the serial data stream. For example if only Sats and Velocity are present the corresponding bit masks 0x00000001 and 0x00000010 would equate to the nnnn0000 bytes equalling 0x0000001100000000. Racelogic CAN modules When CAN channels are also selected to be present in the Serial data stream, the data stream will look like the following: $VBOXII,nnnn0000,stttaaaaoooovvhheeezzmmmggcc $NEWCAN,XXXX,YYYY…..YYYYZZ $NEWCAN,XXXX,YYYY…..YYYYZZ this is the additional CAN channel information to the serial data stream. The ZZ is a two byte checksum. – This is the same format as before see NOTE 1 below. The format for the serial string is $NEWCAN,XXXX,YYYY…..YYYYZZ. Where XXXX is a 32-bit value. The length of YYYY depends upon the val
