The interfaces for the inbound and the outbound bus lines are located on
the front of the module. These consist of 9pin D-type connectors.
The following diagram shows the pin assignment for this interface:
Inbound bus line (9pin D-type plug)

power for the fiber optic converter.
This voltage is not isolated galvanically!
Outbound bus line (9pin D-type socket)
The Interbus coupler has an internal power supply. This power supply
requires an external voltage of DC 24V. In addition to the internal circuitry
of the bus coupler, the supply voltage is also used to power any devices
connected to the backplane bus. Please note that the maximum current
that the integrated power supply can deliver to the backplane bus is 3.5A.
The power supply is protected against reverse polarity.
Interbus and the backplane bus are isolated from each other.
Note!
Please pay attention to the polarity of the power supply!
