RNS 510 data protocols
In data processing, a protocol is the method for exchanging data between computers. The protocol, for example,
the File Transfer Protocol FTP, is to a certain extent the language in which computers “converse”. In order for the
computers to communicate, they need to speak the same language.
The RNS 510 uses two different protocols to transfer data between the control unit with display in dash panel
insert and the navigation system or other control units that exchange display data:
- the DDP display data protocol and
- the BAP operating and display protocol.
DDP display data protocol
In this communication language between the
navigation system and dash panel insert, the RNS 510
takes over control of the display data that should be
displayed on the screen for the Highline version.
A fixed and constant data channel is set up between
the two components via the CAN data bus lines.
The display data protocol runs parallel to the CAN
data protocol for function and diagnosis data.
The telephone preparation control unit also controls
the display data in the control unit with display in
dash panel insert, for example, using the display data
protocol.
The current control units with display in dash panel
insert can currently only process this protocol.
