== Description ==
The CAN bus interface available with the system is accessible through P23 header. P23 pinout is outlined below:
<blockquote>

! Description
|-
| 1
| CAN_VCC (5V)
| If your CAN bus interface requires 5V or provides more than 5V to node, connect this pin to your CAN bus power terminal.
|-
| 2
| CAN_H
| Connect to CAN_H terminal your CAN bus interface
|-
| 3
| CAN_L
| Connect to CAN_L terminal your CAN bus interface
|-
| 4
| CAN_GND
| Connect to GND terminal your CAN bus interface

== 120&Omega; CAN bus termination ==
CAN bus termination on a node is required with some CAN bus topologies while forbidden with others.
SB-UCM board features the '''E10''' jumper which can be used to enable/disable 120&Omega; CAN bus termination implemented onboard SB-UCM.
Set the bus termination most recommended for your CAN bus topology using '''E10''' jumper.
* Place a jumper cap onto '''E10''' to enable 120&Omega; CAN bus termination.
* Remove the jumper cap from '''E10''' to disable 120&Omega; CAN bus termination.
