Supplying External Devices via the CAN
Connector
A 5-Volt supply can optionally be routed to pin 1 and/or pin 9 of a D-
Sub connector by setting solder bridges on the PCAN-PCI card
(independently for each connector on the Dual Channel versions).
Thus devices with low power consumption (e.g. 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. The opto-
decoupled versions of the card contain an interconnected DC/DC
converter. Therefore the current output is limited to about 50 mA.
Proceed as follows to activate the 5-Volt supply:
Attention!
Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-PCI card. Take precautions to avoid
ESD when handling the card.
Set the solder bridge(s) on the PCAN-PCI card according to the
desired settings. During this procedure take especially care not to
produce unwanted short circuits on the card.
Figure 3 shows the positions of the solder fields on the PCAN-PCI
card. The table below contains the possible settings.
