Serial Data

Serial means one event at a time. In data transmission, the technique of time division is used to separate bits of data sent. The messages sent over a bus are configured serially.

Each message consists of:

1. Transmitter address
2. Length of data
3. Receiver address
4. Command or Information
5. Detailed description of message (data)
6. Summary of transmitted information (check sum)

All of the connected control units will receive the information but only the unit in the address will accept and react to the data.
