Just purchased an OTA tuner D2A converter box (DTX 9900) and my URC MX-850 doesn't list Digital Stream as a manufacturer. The user manual lists a vendor code (1234) and has a table of IR Code Listings:

00FF Power
08F7 Ch_Up
09F6 Ch_Down
06F9 Vol_Up
etc. etc.

How do I convert this into something the MX-850 can use?

Can you learn the commands? You would be better off.
The codes could be created using MakeHex but it would be a waste without knowing the carrier frequency.
Besides that, I haven't had any luck pasting hex in the 850 program.

That would be easier if available.


What you need to know is the "protocol" and maybe the device number.

That "vendor code" would give the device number if it is correct, but I don't trust "1234". That value has me worried that whoever wrote the documentation put that in as a placeholder until they could find the correct value, then forgot to change it.

My first guess for protocol would be nec1. If "1234" is correct, it means device number 18.52
The first two digits for each hex function number should be translated from hex to decimal to get the decimal function number (0=power, 8=Ch_Up, etc.)


After using MakeHex, use either Hex2CCF or IrPanels to convert the MakeHex output to a CCF file, then use the Universal Browser in the MX850 editor to drag functions from the CCF.

If you are doing several functions at a time, using a CCF is faster than copy/paste of Pronto Hex. Plus that way works in versions of Universal Browser where pasting Pronto Hex doesn't work.

Those three programs are:

Thanks guys. You must spend ump-teen hours typing in answers on this board for amateurs like me. Don't ever think that it goes unappreciated. Many thanks, and happy Fathers' Day.

1234 is indeed the vendor code that comes up when this remote is tested on an IR detector.

Is there a list somewhere that ties vendor codes to their particular brands?

I am programming the UEI C4000. By matching the device code's vendor#, I have been able to copy Magnavox DVD keys [Skip+/-] that were absent from their TV/DVD profile.
