3.3 Connecting the HMI device
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 configuration 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 (for example, "E-Stand 3" corresponds to version 3).
You can set the following bit rates:
Bit rate in kbps
115.2
