The connector pin numbers are marked on the circuit board itself.
Three operation modes are possible with the SPEA SHOWTIME PLUS:

2. an external board is active
The function of the pinout of the SPEA Movie Bus changes for each mode.
If you need more detailed information about the pinout (and its changes) of the SPEA Movie bus, you can request a technical specification from SPEA Software AG (address to 'Customer Support').
