Pin Patch Area
A component assembled to the SMD1 field will therefore be connected between the device pin and VSS.
A component assembled to the SMD2 field will be connected between the device pin and VCC.
2.1.2 Functional
Area
The Functional Area holds the drivers for RS-232, LIN bus and CAN. Additionally other patch areas are available
as well to directly assemble LEDs, PowerDrivers and connectors to the board.
Note:
For detailed information about the operation of the used RS-232, LIN bus and CAN drivers refer to the related
datasheets of those devices.
2.1.3 Connecting both areas
The Electrical and Functional Areas are not connected to one another except by a common VSS plane.
Nevertheless by use of Jumpers a signal connection between the Electrical Area and the Functional Area is
possible.
The following signals are available on the related jumper fields:
