3.3.1 Supplying External Devices via the CAN
Connector
By setting solder bridges on the PCB of the PCAN-USB Hub (casing
opened) a 5-Volt supply can be routed to pin 1 and the external
voltage supply, if available, can be routed to pin 9 of the D-Sub CAN
connector.
CAN D-Sub pin Voltage Max. current delivery
1 +5 V 100 mA
9 external supply voltage
(9 - 36 V) 2 A
If the solder bridge for pin 9 is set, the state of this pin can be
switched by software (on/off). At delivery pin 9 is on referred to the
