To set the projector to LAN Control Mode, go to the “Function” menu on the projector, then scroll down to “Communication Terminal” and change this from “RS-232C” (the default) to “LAN”. This will set the projector to LAN Control Mode. It will also enable the “Network” option further down in the same menu.
In the builder, browse for Type=Projector+Vendor=JVC. Device is called "JVC Projector RS Series All Models RS232/TCP"
Because JVC disconnects a network connection every 5 seconds if there is no activity, you will have to create an Entrance that is repeating every 3 seconds and put in command called PJREQ that is in the device you import. Tutorial for repeating commands can be found here: http://support.iruleathome.com/customer/portal/articles/471858
In the App, set it up as a NETWORK GATEWAY with Port 20554.
