Hi, so, then i made some last tryings with some remotes: from my old MZ-R 30 : The remote RM-MZR30MP and from MZ NH 700 : The remote RM-MC21 I mesured the resistances (with a non-exact Multimeter) and surprisingly the same functions have roughly the same Values. BUT thy are creating diffent fuctions on the NH700. that will say, that my multimeter is not sufficiant exact (how without a sufficiant amount of digits :-) I also tried your suggestion with the poti and the switch and it works. unfortunately i have only a poti with values up to 20K but it ist also not exact enough (and it is pretty hard to trim exact) and with the messuring error there are already two causes for uncertanties. The most functions I detected were VOL+/- and >>/<< in various Intervalls of resistors. So, for the moment, i have no clue how to proceed but i will buy some more exact Resistors so that at least i can try furthermore. Sofar, thanks for further help, wurzil

Hi I am looking for special Resistor values for the remotes of HI-MD devices. I found a couple of values on the minidisc.org page, but i hope that there are more: I have a old remote from a vaio Notebook with the basic functions of Play, stop, << and >> ( here play and >> is the same button). I plugged this remote in my MZ NH 700 and found out, that the Playbutton is interpreted as an activation(/deacitvation) of the soundsheme (simlple equalizer on/off). Now i am curious if there are some other hidden functions witch can be accessed by other resistance values. My plans are to built a Interface with bigger buttons for the use at home, and in that case it would be quite useful to deactivate the equalizer, activate full volume..... Below, you can find some values I mesured ( doubt that they are superexact, but it is a beginning. notebook remote control (this remote was shipped with a old vaio notebook) play >> 2.53k --> Sound change (NH 700) stop 7.59k << 1.01k Remote shipped with the MZ NH 700 play-pause 333 stopp 7k14 >> 1k018 << 3k68 Group+ 11k92 Group- 5k19 Vol- 8k44 VOL+ 9k93 These values are mesured, so there might be a slight variation to the real values Resistor values I found on some tables on Minidisc.org Mode 14000 Display 17000 Record 19500 Test Mode 24000 Prev/Back 1000 Next/Forward 3627 Pause 5156 Stop 7050 Volume - 8400 Volume + 9900 Track Mark 11900 Thanks for your help, wurzil PS: if I missed some information about that topic please let me know.
