The choice is to use a usb cable to steal power, or a separate terminal in the corner. So jumpering the 5i25 will short things out. But, in the box I used, I'm not sure I have room for 2 of the 7i76D's. So remove the SainSmart, and put its single used input function someplace on the 7i76D seems to be my only choice. But going back to the 5i25, I see I _can_ set p2 and p3 independently. Thank you Peter! W1=down, but W2=up will power P3 only. This will simplify the setup considerably. So to convert the 7i76 to cable power, disconnect my separate 5 volts from TB3-21 & 22, move W2 to rear, and on the 5i25 put W1=down, W2=up. Now I just need enough giddyup to go do it. Can't find it. By the time I fix us lunch, I'll be ready for a nap. Got up too early as the trash collection trucks woke me about 4 AM. Take care all, and thanks to Todd Z. for the reminder. Making me stop and check is always good. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
