This defice has got the front panel display.
Start-up the device.
On the display there should be current IP address (above the "disconnected" line, ignore it for now)
Connect device directly with computer and change network settings, so you will be in the same LAN address space (e.g. if device will be set to 10.41.20.16 - set you ip to 10.41.20.17, gateway to 10.41.20.1 and mask to 255.255.255.0).
Now you should be able to reach MOI admin from PC - change IP in MOI Admin, so MOI will be inside your LAN addressing.
Disconnect everything, setup back PC to DHCP, connect MOI to the router and now it should be accessible.
