The signal RTS (TTL signal) is for the direction control of repeaters, which do not have a self-controlling
capability.
The signals DGND and VP are used to power the bus terminator located in the cable connector.
Note 1 The orientation of the sub-D connector allows the use of PROFIBUS connectors with a 90°
angle cable outlet, e.g ERNI, Delconec and Phoenix.
2 The 9-pin sub-D connector uses #4/40 UNC thread, for mechanical fixation of the cable con-
nector. Make sure that if non-standard PROFIBUS connectors are used, the corresponding
thread is used on the cable connector.
