Codes of a remote control RF (not IR) of Unison Research

[loicgagnant]

Hello All

I have a unison research unico pre but the remote control is missing
It's a RF (radiofrequency) remote control.

I search for a way to prepare a remote control with a system like a Broadlink RM4

I search someone who know the codes ?

Thank you so much for your help

Only RM4 Pro working with RF, at 433,92MHz and 315 MHz.
I'm not sure that proprietary RF remote control certainly use one of these frequencies.

Hello everyone,

I hope you're all doing well.

I have a Unison Research Unico Pre preamplifier, which comes with an RF remote control featuring two buttons to adjust the volume (up and down).

Unfortunately, I don't have the remote control anymore.

I'm looking for a replacement solution.

The Unison Research distributor in France told me that the RF remote is no longer available for purchase.

I received partial information from someone at Unison Research, but I'm still trying to figure out how to get a remote working with my preamp.

I've found the RF receiver board inside the preamp.

According to the manufacturer, there is a button on the board that switches the receiver into rolling code mode, allowing the remote to be paired.

My main question:​

Without the original remote, is it possible to pair any RF remote control?

I tried using a 433.92 MHz garage door remote, but it didn't work.

For reference, when I press the red button on the receiver, a red LED lights up.
I assume this means the receiver is in pairing mode.

Here’s a photo of the receiver module from a similar device I found online:

It's the same module in my preamp, but I couldn’t take a picture because the board is upside down and hard to access.

If anyone has an idea of how to find a compatible remote, that would be amazing!

Manufacturer’s response regarding the remote:​

"Radio remote controls are rolling code and are paired by pressing the red button on the receiver board."

So, this works if you have the original remote... But since I don’t, and I can’t buy one anymore, what can I use instead?

Thanks a lot for your help!
