The PROFIBUS connector on the bottom of the Unit is a 9-pin female sub-D
connector, as recommended by IEC 61158. Fixtures have #4/40 UNC thread
for compatibility with PROFIBUS-DP connectors. No termination is provided
inside the Option Board.

The signals DGND and VP are used to power the bus terminator located in
the cable connector.
The Option Board allows the use of PROFIBUS connectors with a straight
cable outlet.
The 9-pin sub-D connector uses #4/40 UNC thread for mechanical fixation of
the cable connector. Always use PROFIBUS connectors.
Do not use PROFIBUS connectors with a 90° cable outlet (Such connectors
place unnecessary strain on the Option Board connector).
