CHAPTER 3. TECHNICAL DESCRIPTION GÖPEL electronic GmbH
3.8 Onboard Interfaces
The Multibus Controller 6281 offers the possibility to use a total of eight Automotive Bus interfaces. For each bus
(CAN/ CAN FD, LIN/ K-Line, FlexRay and Automotive Ethernet), transceivers are available that can be replaced
with little effort in accordance with the test requirement (see Change of Transceiver ). It also supports up to eight
conventional signals (digital in/ out and SENT), four as input and four as output. Each transceiver type is coded
and uniquely identifiable. Detailed information about the interfaces and how they are supported can be found on
the following pages in the corresponding chapters.
The interfaces are generally supplied with an internal 12 V voltage (VBAT
int
). The supply can also be done externally
(further details for the different interfaces can be found in the respective section). Please note that the external
power supply always affects the two transceivers connected to one RJ.5 connector :

Due to the large number of possible variants, how the various bus interfaces can be connected to the
transceiver slots some variants were defined in order to be able to handle these on the firmware side. The
Multibus Controller 6281 can be equipped with these variants. On the software side the transceiver slots all have
a unique assignment via which the interfaces are addressed. The interface options supported by the firmware
variants can be found in the following table:
