Between the control ground/common,and the ground (- supply terminal) on the Bob. And some means of translating the ground sink from 5 volts to a ground sink on the fwd and rev terminals that have 12.5 volts on them now and would expect a pull to ground to activate them.. Thats opto stuff to me. Slow level translators, but define slow. 3 or 4 microseconds of lag. Shrug. I swear I had a bag of moc-3020's, can't find them. So I bought a 4 channel 5v to 12 volt on ebay just now. At least 15 days delivery. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
