Features
The S7-200 RS-232/PPI Multi-Master Cable comes factory set for optimal performance with the
STEP 7--Micro/WIN 3.2 Service Pack 4 (or later) programming package. The factory setting for
this cable is different than for the PC/PPI cables. Refer to Figure 1 to c onfigure the cable for your
application.
You can configure the S7-200 RS-232/PPI Multi-Master Cable to operate the same as the PC/PPI
cable and to be compatible with any version of a STEP 7--Micro/WIN programming package by
setting Switch 5 to the PPI/Freeport setting and then selecting y our required baud rate.
The USB cable requires STEP 7 --Micro/WIN 3.2 Service Pack 4 (or later) programming package
for operation.
Tip
For more information about using these c ables, refer to Chapter 7, Communicating over a
Network.
