As an option, VEGACOM 557 can be ex-
tended with the adapter print VEGACOM

With the adapter print card, it is possible to
put the Profibus FMS interfaces of
VEGACOM 557 at the front of the carrier. On
the front of the adapter print card, the
Profibus FMS interface is available as a 9-
pole SUB-D plug and as 9-pole SUB-D
socket. The required interface type must be
stated when ordering VEGACOM 557AP.
The following interface types are available:
- RS 485 (Profibus FMS)
Keep in mind that for Profibus the interface
type RS 485 is necessary!
You can find the pin assignments of the SUB-
D plug and the SUB-D socket in the following
