DEMO MANUAL DC2617A

QUICK START PROCEDURE

(Throughout this document, any controller board with

Arduino-Uno compatible sockets will be referred to sim-

ply as Arduino. An example of this can be the DC2026C

Linduino® One)

1. Plug the DC2617A into the Arduino.

2. Provide power to the Arduino. This will also power-

up the DC2617A through the 3.3V power pin of the

sockets. (Do not apply power to the turret labeled VCC

3.3V to 5V)

3. Connect J6 isoSPI to the isoSPI network using a RJ45

cable.

(Alternatively, isoSPI can be accessed using the test

points labeled isoIP and isoIM)

4. Connect J1 CAN to the CAN bus using a DB9 cable.

(Alternatively, CAN may be accessed using pins labeled

CH and CL. It is also possible to connect a USB CAN

dongle directly to J1 by removing the DB9 gender

changer that is plugged into J1.)

Table 1 lists the connections that the shield pins establish

between the Arduino and the DC2617A.
