Recently we have developed new LIN protocols and reorganized them for use on several Motoplat testers. The LIN signal will be now displayed from LIN_1 to LIN_21 together with its ID code. If new LIN protocols appear on the market, we will add more numbers if needed. We did this to make development in remanufacturing easier and cheaper and more clear for customers. Again, you don't need to have a regulator for every alternator, just arrange the regulators in groups or ID codes.
