I have the latest revision of DecoderPro running on my desktop PC, which is connected to a SPROG3 command station. When I press the 'Read type from decoder' button, the message in the lower left-hand corner of the 'Create New Loco' window doesn't change from 'Read MFG ID - CV 8' until the timeout message appears. The LEDs on the SPROG3 box do not flash. The USB connection to the computer is good. I've run the locomotives using my Prodigy power supply with no problems. This issue first occurred on April 27, 2025. Last week, it worked fine. I was able to read data from a new locomotive. I've tried it on multiple locomotives with the same result. Any thoughts would be appreciated. Thanks, Scott

Scott,

It would help to know what brand locos you are attempting to read. I've used a Sprog 3 with no issue, except with BLIs, where sometimes you have to adjust CV 217 (I've posted about that before) to get a successful operation.
