= Description =
The CAN bus interface available with most SB-SOM is accessible through the  '''P5''' 100mil header.
Use jumper wires to connect your CAN node with SB-SOM CAN bus interface as outlined in the table below.

= 120Ω CAN bus termination =
CAN bus termination on a node is required with some CAN bus topologies while forbidden with others.
SB-SOM board revision 1.2 (or later) features the  '''P23''' connector which can be used to enable/disable 120Ω CAN bus termination implemented onboard SB-SOM.
Set the bus termination most recommended for your CAN bus topology using  '''P23''' connector.
Revisions 1.1 and 1.0 of SB-SOM do not provide the CAN bus termination at all.
* Place a jumper cap between pins 2 and 3 of '''P23''' to enable 120Ω CAN bus termination.
* Remove the jumper cap to from pins 2 and 3 of '''P23''' to disable 120Ω CAN bus termination.
