Low Speed CAN / LIN
One fault tolerant, one single wire CAN interfaces and two LIN channels are combined on this DE-9
socket.
The provided GND pin must not be used unless there is no other GND connection. This pin must not
be used for supply purpose.

CAN Breakout Cable (optional Accessory)
Most wire harnesses connect only one CAN bus to each DE-9 connector. Usually they connect CAN-
Low line to pin 2 and CAN-High line to pin 7. Pin 3 is usually GND.

The CAN breakout cable can be used to adapt from the compact pinning used on the MOCCA
compact 2.3 (where up to 3 CAN are available on one DB-9) to three DB-9 sockets compliant to the
standard pinning. The CAN bus with the lowest index on this connector on the MOCCA compact 2.3
is routed to the DB-9 socket with the marking “
I
” and the CAN bus with the next higher index on this
connector is routed to the adapters’ DB-9 socket with the marking “
II
” and so on.
If the adapter is used on the connector “High Speed CAN 1/3/5” for example the connection is as
follows:
CAN no.
