For 12vdc adaptor, does pin = tip = centre ?
Working for small, small organization which just moved. The wall wart for our Gnet Modem/router BBOO73 went missing in the move. Part no longer available. Gnet gave me the specs so I could find a universal one.
All specs understood, and adaptor purchased from R.Shack., BUT the barrel can be installed as tip- or tip+. R.S. instructions say rotate tip according to what the little polarity diagram is on the device. Could've followed that OK, but no such marking on the device. (pffft to Gnet for that one) Gnet tech guy said "pin positive" in his email. Cool. So what's it mean? Hence . . .
naive Q#1: He was talking about the adaptor when he said pin+. The pin he's talking about would be the adaptor's "send" end, not the little pin in the modem's "receive" end, correct?
naive Q#2: Does pin+ = centre+ = tip+.
crux of the matter: the distal end of the wall wart's cable has a little mark that says "tip". When I stick the tip in, do I want the + or the - to line up with the tip?
I'm sure it's pretty straight forward for you guys, but for newbies, it's like . . . OK---on the receive end there's the lining of the hole plus a pin. On the adaptor, there's the barrel outside and the barrel inside, but no pin, unless... the whole thing is a pin not to be confused with the pin at the receiving end . . . [scratching head]. I think I know the answer, but I need confirmation so I don't fry something.
Thanks.
