Ed, >>> 1) I am trying to change the vale of CV 120.9.0, it is set by default to 30, no matter what value I enter and try to program, the value reverts back to 30. The value I enter is shown even when

Bill, The Sunset and Atlas O-Scale locomotive use the FX-DO board, which from the firmware point of view is slightly different from both the FX-U and Titan-G boards, mainly in the motor control circui

Tom, Either order will work to program the two CV's. If you want the correct Programming Verbal Acknowledgement, then you must program CV56.26.1 first, then CV56.26.0. Gerry Pruss QSI

Tom, You programmed CV56.26.0-1 correctly for 56.0 inches. The readout problem was because you programmed CV56.26.0 first, then CV56.26.1. Note the following from page 359 of the DCC Ref Manual versio

KJ, I believe all version 7 firmware supported F7 braking. Some of the very early version 7 firmware (before 13-May-06) may have had a different braking behavior when F7 was applied. Gerry Pruss QSI

Mark, Some time after I wrote that message, we added the capability to upgrade Q1 decoders with Q2 firmware designed to run on the Q1 hardware (Hardware Profile Numbers 1111 and 1121). The following q
