== Description ==
The CAN bus interface available with SB-FX6 is accessible through the '''P61''' 100mil header.
Use jumper wires to connect your CAN node with SB-FX6 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-FX6 board revision 1.2 (or later) supports enabling/disabling the 120Ω CAN bus termination implemented onboard SB-FX6.
Set the bus termination most recommended for your CAN bus topology using '''P61''' connector.
{{note|Revisions 1.1 and 1.0 of SB-FX6 do feature CAN bus termination}}
* Place a jumper cap between pins 4 and 6 of '''P61''' to enable 120Ω CAN bus termination.
* Remove the jumper cap to from pins 2 and 3 of '''P61''' to disable 120Ω CAN bus termination.
