1070 073 822-104 (02.06) GB
X57 Serial port used as an RS-485/422, IPC: alternative to COM2
IPC300: alternative to COM1
This port can be assigned only in the event that the COM2 port (IPC) or
COM1 port (IPC300) is not used. Parallel operation is not possible.
The X57 interface is not suitable as a connection for the touch screen con-
troller of a connected control panel.

Settings
The S3 DIP switch can be used to configure the X57 interface as an RS-485
or RS-422:
D X57 = RS-485 Switch 3 set to ON = TXD is controlled via RTS.
Also, for 2-wire operation, TXD+ must be bridged
with RXD+, and TXD– with RXD–.
D X57 = RS-422 Switch 3 set to OFF = TXD always enabled.
