1.
SA is the source address, DA is destination address, PF is PDU Format, PS is PDU Specific, PGN is Parameter Group Number.
2.
Broadcast interval for CA Speed Sensor status message can be configured (see parameter number 02 in Configuration Parameters, Table 9).
3.
The pulse counter will roll over to 0 when it passes 1,000,000 in a forward direction. The pulse counter will roll over to 1,000,000 when passes 0 in a reverse
direction. The pulse counter will default to 0 at startup.
4.
Checksum = Byte1 + Byte2 + Byte3 + Byte4 + Byte5 + Byte6 + Byte7 + Message Counter & 0x0F + Message ID Low Byte + Message ID Mid Low Byte +
Message ID Mid High Byte + Message ID High Byte
5.
Message Checksum = (((Checksum >> 6) & 0x03) + (Checksum >> 3) + Checksum) & 0x07.
