Is there any way or a program to convert a Pronto pcf file to a URC mxa, mxf, mxd or rcc file?

URC currently does not support PCF imports, and there's no conversion function. However, you can still use elements from a PCF, it just depends on exactly what you're looking for.

Since you're in the discrete code forum, I'm assuming you want to take some IR codes from a PCF and import them into a URC file. For that, download and install ProntoProEdit NG, then load the PCF.

Find the page with the IR codes you want, double-click on a button, then double-click on the appropriate action from the list. If the "Custom IR Code" radio box is ticked, and the hex code below starts with 0000, then select all of it using the mouse cursor, copy to clipboard (CTRL-C), then go into your URC software, open the Universal Browser, hit the little "HEX" button at the top to open the Hex Editor, and paste the hex code into the big white box (CTRL-V). Now click and hold the "DRAG" symbol on the top, and drop the code on a button.

Note that if the PCF file uses database codes, or if hex code starts with anything other than 0000 (such as 5000, 900A, etc) then the URC software cannot import it (trying to "drag" such a code won't work).

This will have to be repeated for every function, so it's only practical if you have no other way to obtain the codes.
