So I can re-pin the "blue" cable and keep the "red" cable in normal pinout and the 450i will get sync from the CMM4? In this figure, it shows the "PIDU", which I am assuming means "Powered indoor unit" aka: PoE injector??? The user guide also leds one to believe that you also need a 56volt power adapter for the CMM4 as well? Why would I need to do that if the 450i gets it's power from the PIDU?
