Variable data length: from 1 to 8 bytes. Variable data length: from 1 to 8 bytes.
First (number zero) byte of every sequence is command mark (0xA5) or data mark (0x5A).
## Commands
CAN ID = 0x680 + Controller address (0..15). Controller with address = 0 is master, it translate CAN ID = 0x680 + Controller address (0..15). Controller with address = 0 is master, it translate

Broadcast messages with ID=0 are ignored. Broadcast messages with ID=0 are ignored.
### Commands and data format
- byte 0 - command mark (0xA5) or data mark (0x5A);
- byte 1 - controller number (packet sender both for command or data);
- byte 2 - command code;
- bytes 3..7 - data (answer of command with DATA mark in byte 0).
So if you want to send command with code `xx` to node `N` from node `M`, you should send sequence of bytes with ID=`0x680+N`:
0xA5 M xx
And you will give answer with ID=`0x680+M`:
0x5A N xx [up to 5 data bytes]
