Supplying External Devices via the CAN
Connector
A 5-Volt supply can optionally be routed to pin 1 of a D-Sub connec-
tor on the PCAN-miniPCI card (independently for each connector on
the Dual Channel versions). Thus devices with low power consump-
tion (e.g. bus converters) can be directly supplied via the CAN con-
nector. The current consumption may not exceed
50 mA
per CAN
connector.
When using this option the 5-Volt supply is connected to the power
supply of the computer. The opto-decoupled versions of the card
contain an interconnected DC/DC converter. In each case resettable
100-mA fuses are interposed.
Important note:
The specification for Mini PCI slots provides a
maximum current output of 100 mA
on the 5-Volt bar. By the
additional current consumption of external devices this limit
can be exceeded and as a result the correct function of the
computer may be affected.
Proceed as follows to activate the 5-Volt supply:
Attention!
Electrostatic discharge (ESD) can damage or destroy
components on the PCAN-miniPCI card. Take precautions to
avoid ESD when handling the card.
Set the solder bridge(s) on the PCAN-miniPCI card according to the
desired settings. During this procedure take especially care not to
produce unwanted short circuits on the card.
Figure 4 shows the positions of the solder fields on the PCAN-
miniPCI card. The table below contains the possible settings.
