Presentation Layer
All commands and messages sent have the format
described in table below.
Description Datatype Length
Header
The header describes the command or message type (e.g. RADC, RMRD, …)
ASCII
character
4 Bytes
Payload Length
The payload length is always sent even if the payload is zero. It is sent as little endian (LSB first).
UINT32 4 Bytes
Payload
The payload is message and command dependent. If the payload includes datatypes (e.g. UINT16, INT32, …) then they are sent
as little endian (LSB first).
Binary data 0 – 3072
Bytes
