1.8 The HMI device in the operating process
PC/PPI cable
You need the cable to update the operating system with reset to factory settings. You can
also use the cable for data transfer. Connect the PC/PPI cable to the RS 422/RS 485 port.
The cable converts the input signals to RS-232 signals.

Set a lower bit rate if the connection is lost during the operating system update. If you use a
high bit rates, you need to use PC/PPI cable version 3 or higher. The version code is printed
on the cable ("E stand 3," for example, corresponds to version 3).
