Configuring the PC/PPI cable
Configure the transmission speed using the DIP switches of the PC/PPI cable if using the
PC/PPI cable to interconnect the HMI device with the configuring PC.
Note
Set a lower bit rate if the connection is lost during the operating system update. If you use a
higher bit rate, you must use the PC/PPI cable release 3 or higher. The version code is
printed on the cable ("E stand 3," for example, corresponds to release 3).
Set the DIP switches 1 to 3 to the same
value as in WinCC flexible or WinCC.
DIP switches 4 to 8 must be set to "0".
In the figure, the bit rate is set to
115.2 kbps.
You can set the following bit rates:
Bit rate in kbps
DIP switch 1
DIP switch 2
DIP switch 3
