From past knowledge, you address each Netx with an iP address, and also a device name, when you open the panel options, you should see ALL available NetX's, you should have named each one different, NetX_Rack, NetX_Desk, NetX_Shades, and so on, then you can address each one in your programming, i have not had any issues in an evironment such as this, the example was from an actual program i wrote about 6 Months ago, each NetX was addressed differently, and IR codes were routed to each NetX correctly, ALL FOUR showed up on the panel, no issues.
