Note
A jumper in the connection plug (counter plug) of the INTERBUS output inter-
face, between pins 5 (+5 V) and 9 (RBST) instructs the electronics to expect
downstream INTERBUS modules. If this jumper is missing, no downstream
fieldbus units are detected.
Standard cables produced according to the INTERBUS standard include this
jumper in their connector.
The +5 V voltage (pin 5) must not be used for any other purpose.
