PCAN-USB Pro – User Manual
11
Two LIN busses can be connected, one to each D-Sub connector.
Figure 2: LIN pin assignment of the D-Sub connector
For the LIN operation an additional supply voltage must be applied
to pin
Vbat-LIN
(8 - 18 V DC, e.g. car battery). Both LIN connections
need their own supply.
Both LIN connections have a common
galvanic isolation
up to 500 V
against USB and CAN. The LIN connections are not galvanically
isolated against each other.
On the PCB of the PCAN-USB Pro adapter (casing opened) a 5-Volt
supply can optionally be routed to pin 1 of each D-Sub connector.
At delivery this pin is not assigned.
