The following describes the settings for the power supply of external devices and the
internal termination. If you do not need any of these settings, skip this chapter.
2.1 Voltage Supply of External Devices
Optionally, an external power supply can be connected via the D-Sub connector
using 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, such as the PCAN-TJA1054
bus converter for Low-speed CAN. Pin 1 and pin 9 are not assigned at delivery and
with the PCAN-USB opto-decoupled only pin 1 is available up to S/N 199999.
The opto-decoupled model of the CAN interface contains an interconnected
DC/DC converter. Therefore, the current output is limited to 50 mA.
2.1.1 Activate Power Supply
Risk of short circuit! Soldering on the CAN interface may only be
performed by qualified electrical engineering personnel.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
