So I wired in my display including the CanBus wiring from my Ecu. I plugged the Ecu CanBus connector to the Usb2Can and the green light flashes and the orange light flashes. The manual says that this means the Usb2Can is working (green flashing) and ‘Data transfer’ (orange flashing) on the CanBus channel.
On the ADU software it says ‘Can 1 - OK’ but shows Disconnected in the bottom left of the screen (Flashing Red).
My obvious thought is, how can the dash communicate via my Ecu CanBus when the preloaded software isn’t configured for it? And how would I get around this when I can’t connect to it?
Hi mfudala, thanks for the reply. I have read that section of the manual but given the connection states ‘Can1 OK’ I was trying to ascertain if this means that the CanBus connection is in fact ok and therefore the issue lies elsewhere.
In answer to your question, I have not tried it yet without the Ecu connected as I’ll need to add in a resistor it its place as the Ecu has an internal 120 ohm resistor for the Canbus and I’m not sure I have one.
Just disconnect your ECU from the CAN bus and enable the resistor in the USB to CAN adapter.
The other way is to open Ecumaster Light Client and check which frames are present on the bus. There might be some that interfere with the connection between the ADU Client and the device.
make sure is connected properly on pin 1 and 2 on emerald pin 1 is can H and pin 2 is can L we have many customers using this with emerald so is not an issue with adu
Hi again Mfudala, I disconnected the Ecu, measured the pins at the ADU connector and had 120 ohms and the same at the end of the CanBus connector so tried it and it worked. Connected 1st time. I then uploaded my saved ‘offline’ setup and made this permanent.
Then powered off, reconnected the Ecu, and tried again and it worked without issue.
Seems odd but it is working normally now. Be interested on your thoughts as to what might be going on.
Thanks Greg, yes made sure of that but I have only recently had to replace my dash with the ADU from using a Race Technology Dash 2 Pro on which the CanBus was working fine so I was confident the CanBus wiring wasn’t the issue.
