What are the values of the pulp resistors on the decoders, and what voltage do they pull up to? If 12V, the yes, you really need to worry about the 2.2K resistors and that 1K series. Even at 5V you may have to do so. Work the problem out on paper - simple ohms law. Then determine if the low

Hi Folks, I am having an issue with the band data out from the K3s and K3S. Both have are basically new. The K3S was NEW in Aug 2018 and the K3s had the I/O board replaced at the same time. Both units have the same issue. They don't seem to be able to drive band data input of a couple of
