Voltage Supply of External Devices
External devices with low power consumption (e.g. bus converters)
can be directly supplied via the CAN connector. With a solder bridge
per CAN channel on the PCAN-PCI Express FD board, a 5-Volt
supply can optionally be routed to pin 1 of the D-Sub connector.
The current output is limited to 50 mA.
Do the following to activate the voltage supply:
Risk of short circuit!
Solder with great care to avoid unwanted
short circuits on the card.
Attention!
Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
Set the solder bridges corresponding to the desired settings.
Figure 4 on page 13 shows the solder field positions on the four-
channel card
(IPEH-004040)
. The solder fields for the single and dual
channel versions
(IPEH-004026/27)
are located in the same positions
and can therefore also be taken from this figure. The table below
contains the possible settings.
Risk of short circuit!
The 5-Volt supply is not protected
separately. Therefore, turn off the computer before you
connect and disconnect CAN cables or peripheral systems.
