Link extreme and Dash 2 connection issue

Recommended Posts

Hello chaps

I’m having some issues connecting my extreme ecu with my race technology dash 2 display.

I have the link canser lead so I can connect the ecu into my laptop and open the PC link software, change the CAN settings and  apply the settings to transmit to my Dash 2. 

I also have a Race technology CAN interface lead which is Pre programmed for the Link G4+ ecu’s.

So when I connect the Canser lead in and connect to the RT CAN interface lead it won’t connect to my ecu or dash 2. So I’m assuming that the serial connector on the canser  and the serial connector pins don’t mate up?  Or that I’m missing somthing else

Any help wuld be great so eat so I can read my ecu settings on my dash 2!!

Thanks

HI Tom 

The CANSER lead was intended for serial coms. It would pay to check that you have CAN L and H wires connected right through from the dash to the correct pins at the ECU.

As the CANSER has the serial wires connected you will loos you PC coms while the dash is connected. 

If using CAN it is best to use the CANF connector and wire the CAN wires direct from the dash can lead.

Hi Simon 

As I have the Dash 2 and not the Dash 2 pro, I don’t have a pin out directly t the dash for CAN.

From my understanding the RT CAN interface lead help with this and converts the serial to CAN,

Do you know the pin out of the CANSER lead?

in my mind I’m thinking to cut the serial connector off the end of the lead then connect it to the RT lead? The F connector may be handy buying as well I guess

Or go for the

Correct, that won’t work as the CAN wires won’t be connected in the CANserial cable.  You will need to make your own using the CANF similar to the dash2pro instructions here:  

 

Buy a Female DB9 connector for the race tech end and pinout is here: https://www.race-technology.com/wiki/index.php/CANInterface/PinConnections

Hey adam

Thanks for that buddy

 

Ive taken some pictures, as I’m wondering if I can cut the serial connector off the CANSER lead and then joint to the two wire High and Low serial connector, which then connects to the ecu labelled serial connector.

Ive taken some pictures so you can see the RT lead.

The only thing I need to know next is the pin out of the CANSER cable, so I know which wires to connect the red and white CAN wires to.

i under stand the theory of it, just gotta work out if I cut the £50 CANSER lead or not hahaha

 Cheers

Tom

So if I follow this diagram will this work for the CANSER cable as I believe this is the CANDASH diagram.

 

if I cut the serial cable off and just connect up the CAN H and L from pin 3 and 4 to the CAN port interface serial connect plug I’m thinking this should work then?!

I don’t think the CANSERIAL cable has the CAN pins connected so don’t cut that up.  As mentioned earlier you need to make your own using a CANF and DB9

 

So got the CANF connector delivered, connected that onto the 2 pair twisted wires for the CAN H and L and still not showing the readings on my race tech display. Didn’t need a db9 connector as the RT CAN interface lead has them on it. So think it may be an issue the RT side of things.

Seems I’m missing somthing, can’t get the ecu and display talking!
