I have a Zypher set and am able to program cv's and run locomotives with Digitrax decoders. No problem and very cool. Then I go and put aTsunami into a KATO GS-4 and find the Zyphyr will not read back cv set points of the Tsunami. I purchased a so called " booster " and still no worky. I contacted Digitrax and they had no real answers for me but suggested I change a value in the command station. Still no worky. I can change cv values but it will not read back values. Does anybody have a suggestion for a different brand of DCC command stations that WILL read back and change cv values of a Tsunami? Is the JMRI computer program the best way to program decoders, both sound and no sound? Appreciate any feedback. Carl
It's not just the Zephyr. I can't get Tsunami equipped and MRC equipped (Athearn) locos to ready back on a Super Chief. I did read somewhere that the MRC facotry installed decoders are designed not to read back. Not sure if that would apply to other decoders.
It is usually not a problem with the command stations. Some decoders do not draw enough current to commuicate with the command stations as specified in the NMRA standards and RPs. This issue has been recently discussed in this thread: Is there a trick to programming the Athearn Challenger (N scale)? - TrainBoard.com
Just a thought. Try Direct mode programming. That's Pd on the display. Press the program button repeatedy until Pd comes up. This may work with the Tsunami. Forget about reading the MRC decoder in the Athearn. MRC didn't put read back in those. Best bet is to use JMRI with a roster entry or just write any changes down for later. Martin Myers
