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?

What you want are IR Zones. I do not believe any power related solution will work. You might try shileding the TV's IR receiver so it needs a direct on signal by using some sort of tube in front of the receiver.

I do not know if the TV's allow their remote controls to have different device codes, I suspect not. Sony does that as do other mfg's for many classes of products. If the TV remotes allow for selection of a remote control device code or sub code you are home free.

Since I do not use an RFX9400 for IR I do not know if it has separate zones but I am sure someone here does. If so It should be doable by selecting different zones (RFX9400 IR Output ports).

Regarding your TV problem

Add a xantech connecting block 789-44 to the IR port outputs of the RFX9400 to expand port capacity and use stick-on emitters for the TVs if you cannot utilize different codesets as Barry mentions. Xantech CB in this configuration, should not even need a power supply.

This will be your best solution.

With regard to 'System is in use', you will need to either buy another RFX9400 and put dual emitters to all equipment the remotes need to control or live with the issue.

If you suspect that you have an IR bleed issue, keep in mind that many materials, such as black electrical tape are not completely opaque to IR emissions. I usually mask with black electrical tape, backed with a layer of aluminum foil. The foil is opaque and the black tape hides the foil and is usually very hard to detect. (Typically, it is black tape on black in a poorly lighted area)
