26. Simple Protocol VS Full Protocol
Checksum over messages
No acknowledgement
No retransmissions
No line checking
Controller can check use SC_C_CHECK_LINK function
Full Protocol
Line checking
Starts after first message
Acknowledge of message reception
Retransmissions on failures
We will use Simple Protocol in this training!

28. Header Message Checksum Type Length Data Protocol Layout
Currently the following types are defined for communication with the CCU:
MDSM_REMOTEPROCEDURE_REQ : Always transmitted to the CCU.
MDSM_REMOTEPROCEDURE_RSP : Respons back from the CCU
MDSM_NOTIFY : Notification from the CCU

Checksum Byte
The Checksum is calculated using the following sequence:
Sum all bytes over the header and the message.
Take modulo 256 of the calculated checksum and do a bitwise invert of the checksum.
This calculated checksum is sent along with the packet. The receiver executes the same calculation and verifies the calculated checksum with the received checksum.
