I am trying to program a blank 58818 using the Decoder tester. Laptop to LokProgrammer reading existing sound files works fine. All items hooked up and working fine but just can't get the decoder to be recognized. Deleted all programs and downloaded all ESU software again. It still cant detect 58818, whether I try to read the blank or try to Perform a complete decoder update. Once it gets to reading CV's it shuts down.
