I have two EZ Command control boxes that I picked up used with different power adapters. One is AC 16v output and won't power either box. But the other is DC 16v output that works on both. I assume the DC 16v output is the correct one but am I right?
According to the EZ-Command instructions:
After the track connections are complete, plug the Wall Pack Power Supply into a standard 110 volt wall outlet (figure 5). Plug the wire from the Wall Pack Power Supply into the socket on the E-Z Command controller labeled "16VDC IN"
