2.7.6. Serial Ports
In all, the module is equipped with three serial communications interfaces, each of
which is connected using a 9-pin Sub-B socket. X8 is a potential isolated RS485 in-
terface, while two RS232 ports are available at X4/X5.
The RS232 port at X4 has an exception setting!
Depending on the configuration it can be used as either a Linux console, or as a
PPP interface for remote maintenance or a CoDeSys programming interface.
If the DIALOG CONTROLLER is started in the configuration mode, the device
can be configured in this mode using a serial PPP link. Here too, connection is
via X4.
