Put a small piece of electrical tape to cover the entire top of the USB connector.

Make sure to move the switch on the CAN shield to the “ON” position (see Picture above). Pin 2 = ground Pin 3 = CAN-H Pin 5 = CAN-L Pin 9 = +12v Be sure there are no stray wire strands touching anything. If the wire is too thick, cut off a few strands. Strip about 3/16 inch of insulation off each wire end and connect to the DB9 screw terminals. The wires associated with these pins (above picture) are connected to the DB9 connector via the screw terminals. The wiring connections on the 4 pin DT-4 connector are: +12v, ground, CAN-H and CAN-L. You could also just fill the hole in the box where the cable goes through with silicone sealant.

Just get one that will fit your cable diameter. The cable and waterproof gland nut (shown in Quick Start section of main page) used on the DUE assembly can also be used with the UNO.Īs an alternative to the “Gland nut” you can use a rubber grommet, which can be purchased from most hardware stores, such as ACE Hardware. Do not cut too deeply so as to damage the board. The run can be cut with an X-acto knife or box cutter. The wire trace is connected between the blocks labeled P1 on the back side of the shield. Cutting this run removes a termination resistor that is not needed when connecting the simulator to the vehicle. The Seed CAN shield will need a small wire trace to be cut before use. The CAN shield (V2) is made by Seeed Studios and can be purchased directly from them, Amazon or other online retailers.

The Arduino UNO or equivalent can be purchased from online retailers such as Amazon. Please see the Programming section at the bottom of this post. Note: It is highly recommended that you program the Arduino board before starting the assembly of the DEF simulator. The UNO/ATMega2560 boards require the use of an additional board called a CAN shield. The DEF Simulator can also be built using an Arduino UNO or ATMega2560 board.
