CAN Bus

Common Area Network Bus (CAN Bus) is a widely used data interface common used in many cars and

aftermarket accessories (such as Data loggers and Dashes). Data is sent using the High and Low wires,

which are maintained as a twisted pair.

The X20L as default has 2 x CAN bus interfaces:

CAN0 is used for expander communications with the Syvecs Engine ECU. (120ohm Termination Resistor)

CAN1 is available for generic use but can be used also for bridging the custom can data from CAN0 to

external dashboards. This is enabled as default for Syvecs expanders, where the custom can data from the

Syvecs Engine Ecu will be passed through the expander CAN0 to CAN1. (120ohm Termination Resistor)
