Supplying External Devices Via The Can Connector - Peak PCAN-USB FD User Manual

PCAN-USB FD – User Manual
3.2 Supplying External Devices via the CAN
Connector
On the PCAN-USB FD board (casing opened) a 5-Volt supply can
optionally be routed to pin 1 of the D-Sub connector. Thus devices
with low power consumption (e.g. external bus converters) can be
directly supplied via the CAN connector.
When using this option the 5-Volt supply is connected to the power
supply of the computer and is not fused separately. A DC/DC
converter is interconnected. Therefore the current output is limited
to 50 mA
Proceed as follows to activate the 5-Volt supply:
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. In order to access the board, 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 solder bridge on the board of the PCAN-USB FD
adapter according to the following figure.
During this procedure take especially care not to produce unwanted
short circuits on the board.
Figure 2 shows the position of the solder field JP4 on board of the
PCAN-USB FD.
