2.2 Voltage Supply of External Devices

Attention! The voltage supply for external devices is not protected
separately. Therefore, turn off the computer before you connect and
disconnect CAN cables or peripheral systems. Consider that some
computers still supply the USB ports with power even when they are
turned off (standby operation).
Optionally, an external voltage supply can be connected separately for each CAN
channel via solder bridges at pin 1 and/or pin 9 on the D-Sub connector. This allows
external devices to be supplied with a voltage of 5 V DC, for example bus converters
(PCAN-TJA1054 for Low-Speed-CAN). Pin 1 and pin 9 are not connected at delivery.
The current output is limited to 50 mA.
