4.4.4 “X1” and “X2” ETHERNET Interfaces
The ETHERNET interfaces are RJ-45 ports. The orange LED illuminates when
there is a LINK and the green one blinks during data transfer.
The connectors and cables meet category 5e requirements and guidelines for
ETHERNET interfaces.
The integrated 10/100Mbit ETHERNET switch supports Auto-MDI(X).
A crossover or patch cable can be used.
4.4.5 “X3” – RS-232/485 Serial Interface
(Only with PIO3 Hardware)
This interface is designed as a D-sub 9 socket and is electrically isolated from the
supply voltage of the panel and the other interfaces. Baud rates from 1200 to
115,200 are supported.
The socket combines an interface as per RS-232 and an interface as per RS-
485. However, the two interfaces must NOT be used simultaneously!
These communication partners must be set to the same interface type, since the
voltage levels of the two types are NOT compatible!

NOTICE
Incorrect parameterization can damage the communication partners!
The voltage levels for RS-232 and RS-485 are not compatible!
If the controller interfaces differ from those of the communication partners
(RS-232 <> RS-485 or RS-485 <> RS-232), this may damage the interface
of the communication partner. Therefore, always ensure that the controller
interface matches those of its communication partners when configuring
these items!
