Activate Internal Can Bus Termination - Peak PCAN-MicroMod FD User Manual

4.2 Activate Internal CAN Bus Termination

For correct termination of a High-speed CAN bus (ISO 11898-2), a 120-ohm resistor
must be inserted at both bus ends between the CAN-High and CAN-Low lines. If the
PCAN-MicroMod FD Analog 1 is to be connected to one end of the High-speed CAN
bus, the internal termination can be activated to take the termination on this side of
the CAN bus. This is done with a switch on the board. For this you have to remove it
from the casing.
Tip: We recommend terminating the CAN cabling directly, for
example with termination resistors. This allows CAN nodes to
be flexibly connected to the bus.
To open the casing and remove the circuit board:
Attention! Electrostatic discharge (ESD) can damage or
destroy components on the circuit board. Take precautions to
avoid ESD when handling the circuit board.
1. Remove the mating connectors from the device.
2. On one connection side of the casing, remove the two screws to the right and
left of the connector and remove the plate including the rubber sleeve.
3. Pull the board out of the side of the casing.
4. For later assembly, proceed in reverse order.
