Instructions for bus wiring when using the interface
R For bus wiring screened cable has to be used!
R The bus wirings (incoming and outgoing leads) always have to be applied directly to
the device (no branch boxes)!
R In the devices at the end of the busses the terminating resistors integrated in the
device have to be activated (DIP-switch ON).
