CAN BUS Mercedes W124

Sure, here's the translation:

'Hi there,' or 'Hello,' or 'Good morning.'
'Can anyone tell me if it's possible, and if so, how I can display the live data from the engine control unit (ECU) of a W124 E280 with an M104 engine and a 16-pin Mercedes diagnostic connector on an external screen? While it's generally not a problem with OBD vehicles, I'm not really familiar with this older data protocol. The engine(s) are going to be installed in a boat, and the data, along with NMEA 0183/2000 data, needs to be displayed on an external screen.'
Whoever provides helpful information first may also have the opportunity to ride along .

Hello.
It would be enough for me if someone knew whether it's a J1939 protocol.

No... with that model series, a K-line diagnosis was still performed, which involved connecting to the diagnostic line and then outputting a blink code via a pulse width.
