RS-485 JUMPERS POSITION

CAN port

The CAN interface is based on the Microchip MCP2515 stand-alone Controller Area
Network controller and the Microchip MCP2561 high-speed CAN transceiver. They
implement the CAN specification version 2.0B, and support up to 1 Mbps speed.

The CANH and CANL lines are available on the terminal block.

The CAN transceiver’s TX and RX lines are isolated from the CAN controller with
dedicated opto-couplers. The CAN transceiver is also galvanically isolated from the CAN
controller and the Raspberry Pi in general with the same high-efficiency DC-DC converter
used to power the RS-485 line drivers.

A 120 Ohm termination resistor between CANH and CANL can be enabled installing
jumper JP3.
