I have the following setup

2x TSU9400
1x RFX9400 (fully populated)
2x Clarion Flip down TV (IR)
1x Sonance iPort (IR)
2x Scion (2x IR over RF)
1x Extron Matrix (IR over RF)
1x Keene volume control (IR over RF)

The room has two bunk beds, each with their own flip down TV

The problem is the IR signal from the TSU9400 is too powerful and controls both flip down TVs. (The signal bounces off the walls)

Is there a way to reduce the power of the IR signal for the flip down TVs, but use full power for the iPort?

Also I sometimes see a message saying something like the other user is using the system, try again. Is there anything I can do about it?
