This is great. I have one question. I assume that the DCC stationary decoder does need to be powdered and it can be powered by either batteries or AC/DC 9 volt adapator. Have you thought about using a soundtraxx decoder to add sound to the engines (...) (21 years ago, 4-Jul-03, to lugnet.trains)

1.04beta isn't working with nqc 2.2r1 for Linux :(. After the download completes I get a SOUND_FAST_UP then the LCD goes blank and the RCX is completely unresponsive. I have to pull the batteries to reset it. This happens with both lacc104.srec and (...) (21 years ago, 7-Jul-03, to lugnet.trains)

(...) I was wondering if there is a DC component to the DCC signaling such that you could actually draw the power from the track to power the decoder RCXs? SteveB (21 years ago, 8-Jul-03, to lugnet.trains)

Ok, I think I have it fixed. Apparently, nqc doesn't like .srec files that have gaps in the memory sequence. So, I just added some zeroes in those spots to makes things copacetic... :-) I tested it with the Win32 version of nqc 2.4 a4 and it seems (...) (21 years ago, 8-Jul-03, to lugnet.trains)

Just curious: Would it also work if the booster is powered by an external source and the LDCC RCX draws its power from the track? Or does the booster have to sense the presence of the DCC controller before it supplies power? (...) (21 years ago, 9-Jul-03, to lugnet.trains)

Well done! and THANKS! I tried Sunday night to use lacc as both a decoder and booster, but I didn't have a proper "sensor" (couldn't find my second 9v light), and none of my jury-rigged versions did the trick. I'll pick up some resistors and build a (...) (21 years ago, 9-Jul-03, to lugnet.trains)

Yes (to the second question :), the booster code will cut power if the polarity of the track power hasn't changed for 10 milliseconds (or if no power is detected). Basicly, the command station is always sending out packets by flipping the polarity (...) (21 years ago, 9-Jul-03, to lugnet.trains)
