SEGA 837-14509-02 USB -> Serial Adapter hook
|
||
|
|
|
||
|
|
The 837-15093-06 LED controller is connected to the ALLS with an adapter.
|
||
|
|
This tiny board has a FTDI FT232BL chip, and is referenced in schematics as
|
||
|
|
"USB-SER I/F BD".
|
||
|
|
|
||
|
|
The game queries the presence of the FTDI board itself, followed by a
|
||
|
|
registry check to see which port number is assigned to the FTDI board.
|
||
|
|
If these fail, the "CABINET LED" check on startup will always return "NG".
