It would be nice to know exactly what the OP means. I assume it's common knowledge that RF universal remotes convert RF to IR all day long. So I have to guess that the OP meant he has some OEM RF only remote and wants to convert it's output to IR. I have no idea why anyone would need or even want to do that, but if they did, it would be very complicated to build a transceiver to demodulate, re-encode and modulate back to the standard 38kHz IR frequency. I imagine the best way would be to tweak an existing universal remote's RF/IR transceiver.

He probably actually needs an IR to RF converter so he can use his universal remote to control some OEM RF device.

I have a monoprice motorized projector that has an RF remote.

Can I use a Universal to control it?

Something like a harmony 890 or an RF20 by URC.

I'm leaning toward the RF20 (price) but don't know if it can send the right frequency to control the screen....thinking that maybe the remote can only RF to the RF to IR transmitter/blaster.....does anyone know?

I realize it can learn various IR "codes" but can it learn different RF frequencies?

No. RF universal remotes only use RF to communicate with their specific RF to IR base station and some remotes can control certain brands of RF lighting (such as z-wave).


If you have something that is controlled only with an RF remote (your motorized projector) then you will not be able to use any other remote to control it. If there is an IR input option then you should utilize that instead.

I know this is two years old so maybe there is a way to do it now? I have same situation, want to control my rf projector screen from harmony Remote

There is an official solution for Harmony remotes for at least one RF device; the Harmony PS3 adapter. It has an IR receiver and an RF transmitter. Tranceiver actually. It basically simulates a bluetooth remote to the PS3, and listens to the Harmony via an IR receiver. You pair it wirelessly to your PS3, and then in the Harmony software, you add a PS3 as a device, and ignore all the warnings about "your remote can't talk to this device", and it works perfectly.


The misleading warnings seem to be because the Harmony software predates the PS3 adapter product, or at least they never bothered to update it about that. I mean, come on, the Harmony software calls all optical discs "DVD / Laserdisc". That includes bluray, which is nowhere to be found in the software.

but this won't actually help control an RF screen right?

I know this is old but I may need to convert the new TIVO Roamio RF remotes to I since I use a Xantech wired IR control system to get signals to an equipment closet. I'm afraid the closet is too far for the RF to make it through brick walls, etc. But I have IR receivers in adjacent rooms. If I use the common IR to RF converters and just use the equipment end (RF to IR) in the rooms the problem would be RF going to more than one RF to IR blaster and jamming the IR bandwidth (easy to do). What I need is a device to receive the Tivo IR signals from an old Tivo peanut and convert them to RF for the Roamio. If I can't resolve this I can't use the 6 tuner Roamio.
