I see where PR has out a DC cord that hooks up to the Dreamstation units and an automotive cigar lighter plug.
There has been talk/speculation as to the requirement for a mystery signal along a third wire as a requirement to make a Dreamstation run.
Anybody have experience with this? I ask because the PR system doesn't make you go through a brick - it is a simple two wire cord assembly. Or looks like it. Has anyone gotten the cord or taken it apart to see what makes it tick? It seems if it is really just a two wire cord (with two inexplicably ginormous RF chokes), then what/where is the mystery third conductor signal coming from? And if it is maybe a resistor molded in the plug end, shouldn't I just be able to run off a battery/DC source if I cut off the cigar plug and the RF choke on that end and replace with a PowerPole connector to hook up to my battery backup???
