Can't see iTach WF2IR

I set up the unit with it’s own IP address on the network, but when I try to add the iTach WF2IR via the web interface, it doesn’t appear in the list. Nothing appears in the list. What is the “trick” ?

Add the global cache gc-100 app. Record your ip address in the advanced tab and it will create three hidden devices, one for each ir sensor output.

OK, that’s done and now I keep receiving NO IR BLASTER message when I try to setup my receiver. I’ve try any combination of port and it’s always the same.
