How do you replace a Ln card when you don’t have the Lon config file. The Ln in the cop is dead no stat light and is not communicating through Lon explorer or manager. I have replaced lens before but Always had the Lon config file. Seems like there is a way to do this manually but I can’t find any info on it. Has anyone done this before?

The LON cfg file is just a text file. If you download the LON cfg now it should have everything but MAINCOP1. You can use the IO map to fill in the blanks where they belong. It would be helpful to find a similar car, download it’s LON cfg and take a pic of it’s IO map to reference. # of ports has to match the number of L24 cards +1 for the LN card, for the car. The hall would be just the number of L24s, no used port on The LN. you’ll notice the IOs are not layed out like your IO map in the Host but they do need to be in the LN Node.
