dc/dc converter

[dubiousss]

So finally finished the ring stinger and moved back to the maestro ring mod. It calls for +12 -12 +15 -15 voltage. So I have this part NTH0515MC ( http://www.murata-ps.com/data/power/ncl/kdc_nth.pdf ). So i figure ill get a 5vv regulator and then run it into this thing. I didnt have one lying round so i divided the voltage from a 9v regulator. Anyway I wasnt to sure about the setup I pluged the +5v into +Vin and connected -Vin to ground but measuring the voltage on -Vout and +Vout or 0V didnt give me any reading, I also tryed connecting 0V to ground but nothing, Then I think I fried the thing by connecting 9V to it and got a 50V reading from one pin. Perhaps no volts are shown if there is no load but I didnt want to fry the rare chips in the maestro.

Others have told me to make a transformer power supply but it wouldnt fit in the enclosure I have. Ive built some op amp converters but they didnt have enough juice to power the thing.

Anyway all I want to know is do I plug -Vin to ground, +Vin to 5v, then -Vout to -15 and -12regulator and +Vout to +15 and +12 regulator and leave 0V alone?
