6 Installation
6.1 CAN bus Termination
Each end of a CAN bus must be terminated by a 120 ohms resistor between the CAN bus lines CAN
high and CAN low.
This termination could be activated by installing jumper on the jumper field J4/J5 and J8/J9. Because
of split termination there are two jumpers for each channel.
Bus line termination for CAN bus channel 0 active: Jumper J4 + J5 (1-2) installed
Bus line termination for CAN bus channel 1 active: Jumper J8 + J9 (1-2) installed
To set the termination of a CAN bus I/O channel, always use both jumpers for that channel.
