  • Appears to be problem with CAN bus, LED indicates Bus Off and measuring 600 ohms

Kyle,

We verified that the input bus (Bus3) is at 60 ohms with everything powered down. I did not have it powered off when I was taking that measurement while on the phone with you.

We now have that plugged into Input 3 on the bridge. While I have my CAN-USB device hooked up to view the bus the light is LED is green on the bridge. When I don’t have my USB-CAN device hooked up it is RED.

Kyle,

Here is a CAN log with both the input to the Bridge, and the ouput in one trace. The Input (CAN3) is bus 1 in this trace and the output (CAN4) is bus 0 in this trace. By this it appears that it is working ok now. I’m not sure why we still have a red LED on CAN3, but it seems to work regardless.

I don’t see any error frames with my CAN tool (Kvasar USBcan) on that bus…

Can you verify the color and whether or not it is steady or flashing?

Kyle,

I think I finally got it all working. I believe that the issue that I was running into was that the controller that I was brining in on CAN3 (A weather station) doesn’t work unless it sees something else on the bus. It would work fine when I have my Kvasar hooked up. Had issues with it unhooked.

I think I am good now. Thank you for the help.
