DEMO MANUAL DC2617A

JUMPER SETTINGS

JUMPER JP1

FUNCTION

Set JP1 to ARD

Establish SPI communication between Arduino and MCP2515. In this setting, MCP2515 handles the logic

communication between SPI and CAN. LTM2889 is the physical layer CAN transceiver.

Set JP1 to NUC

Establish communication directly from pins CAN1_RX/CAN1_TX (J2) to LTM2889. This can be useful in some

controller boards such as Nucleo, which have built-in CAN functionality which comes out on these pins. LTM2889 is

the physical layer CAN transceiver.

JUMPER JP2

FUNCTION

Set JP2 to ON

Termination to LTM2889 is turned on. See LTM2889 data sheet for details.

Set JP2 to OFF

Termination of LTM2889 is turned off. See LTM2889 data sheet for details.

Use the following jumper settings to further configure

the DC2617A:

CAN BUS POWER

LTM®2889 includes a built-in isolated power supply that

provides an isolated power output (5V) on the same

ground domain as the isolated CAN bus. This output

can be accessed using pins V2/G2 on connector J7. See

LTM2889 data sheet for details.
