I just received a new smarthome 2413S and have tried this PLM also. Still no communication. I tried just talking PLM to PLM – nothing. The SHN utility can also not display any link records of any devices.
My ISY can communicate with the EZIO though. So without disturbing anything, I unplugged the ethernet cable going into the ISY and plugged it into my serial/usb adapter. Still cannot communicate with the EZIO. This is making me think the problem is in my serial cable. It’s as though the transmit is working but not the receive.
Is there a wiring diagram for both ends of the serial cable so I can confirm this cable is wired correct.
