hooking up the Jeff Muchas shutdown controller?
so my Muchas shutdown controller came today, but i have a quick question about hooking it up. I see there is a Vin, GND, GND, Vout and AUX connectors. Obviously I know what Vin, Vout and GND. I assume AUX is the ACC wire, since there is nowhere else it would go, but what I am confused about is the second GND. In the diagram on the PDF on Jeffs site it looks like the shutdown controller takes in a Vin and GND and puts out Vout and GNd (which both go to the PSU?????) and then the PSU is grounded seperately?
Is this right? It seems coutner intuitive that i would feed the PSU a GND and then ground it. Shouldnt i jsut feed the PSU the Vout and ground it? What am i missing?
Thanks for any info. Jeffs site is Mpegbox.com and there is a link there to the solotronix store which has the shutdown controller/spec sheet.
