CAN Termination

The termination can be activated by solder jumpers on the board. At
delivery the termination is not activated. A High-speed CAN bus
(ISO 11898-2) must be terminated on both ends with 120 Ohms.
Otherwise disturbances may arise. If a CAN bus is not terminated
correctly, activate the internal termination.
To activate the termination, the solder fields JP1 and JP2 must
be soldered. Proceed as follows to activate the termination:
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-USB FD board. Take precautions to
avoid ESD when handling the card.
1. Open the casing of the PCAN-USB FD adapter by cautiously
pushing in the latches on both sides, e.g. with a flat tip
screwdriver.
2. Remove the board.
3. Set the both solder bridges on the board of the PCAN-USB
FD adapter to activate the termination.
During this procedure take especially care not to produce unwanted
short circuits on the board.
Figure 3 shows the positions of the solder fields JP1 and JP2 on
board of the PCAN-USB FD.
