Using a HUB101 or BBWX2 with the proper "Power Sync" settings, a power up signal is passed to the devices (like DFF1) over the Ethernet using wires 4 and 5, from the MFDs. (normal Ethernet communications use wires 1,2,3,6). Each unit still needs it own power cable. The power sync is only the "Switch" to turn the unit on. the DFF1 is not "POWERED" from the hub. It should have its own power cable/connection. It is only switched "On" by the hub from the MFD. The Hub needs it's own power cable and it is NOT turned/on and off by power sync. Currently only the following items use power sync.
MFD's
DFF1
DDF3
PSU012
PSU013

Pass but don't use Power Sync....
Hub101
BBWX2
Again each unit still needs a power cord connection. Nothing gets it's main power from anything else.
