Setting the transfer rate (DDL mode)
The DDL transfer rate is determined with the 5-pin S2 DIP
switch on the front side. All DDL participants must be set to the
same transfer rate.
Table 6: DDL baud rate
Switches Bit Open
S2 (5 bits) 5 DDL 125 kBaud
The transfer rate can be set as follows:
1. Open the cover of the S2 DIP switch.
2. Move the S2.5 DIP switch to the desired position (see also
Fig. 3: S2 DIP switch).
3. Close the cover of the S2 DIP switch.
Configuring the bus coupler

Starting the SERCOS III interface

The bus system is connected using M12, 5-pin, D-coded data
plugs. The physical sequence of the devices in a SERCOS III
system can be chosen arbitrarily. The X7E1, SERCOS III and
X7E2, SERCOS III connections are thus interchangeable.
