The change “under the hood” is significantly larger than the version number suggests. The internal timing has been completely adjusted. In principle, you shouldn’t notice anything, but the goal is, among other things, to be able to work with more and longer DCC packets in a future step. That isn’t possible yet, but the current change is a prerequisite to get there.For this reason, TM44 1.23 absolutely does not work<\/strong> with older versions of TM44 firmware and also absolutely does not work<\/strong> with current TM-H versions. <\/p>\n\n

One change you might notice is that the drivers on the TM44 can be controlled in two ways when running on pulse width modulation (i.e., “analog operation”): Fast Decay and Slow Decay. Without going into the technical differences, the effect is that Slow Decay shows significantly better slow-running behavior for small scales. It is very clearly noticeable in Z scale and reportedly also with many models in N scale. In H0 scale, I can hardly detect any difference myself. See also this extensive thread<\/a>By default, the TM44 1.23 is set to Fast Decay. The reasons are: <\/p>\n\n
