Supplying External Devices via the CAN
Connector
A 5-Volt supply can optionally be routed to pin 1 of a D-Sub connec-
tor by setting solder bridges on the PCAN-PCI Express card (inde-
pendently for each connector on the dual or four-channel version).
Thus external devices with low power consumption (e.g. bus
converters) can be directly supplied via the CAN connector. By
using interconnected DC/DC converter 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-PCI Express card. Take precautions
to avoid ESD when handling the card.
Set the solder bridge(s) on the PCIe card according to the desired
settings. During this procedure take especially care not to produce
unwanted short circuits on the card.
Figure 5 shows the positions of the solder fields on the PCIe card.
The table below contains the possible settings.
