Ok. i'm sorry everyone, i've searched the previous posts and gotten a little farther than i was before I need to input my discrete IR codes into my MX-850 for a Samsung LN-S4692D. I went to the manufacturers website and looked up the discrete codes which directed me to a PDF file. i dont know what to do from here. i've downloaded the prontoEdit program as well as homevision native IR to Pronto Hex. I've also downloaded MakeHex which isn't working (after extracting all files and cliking Makehex icon a dosprompt flashes and nothing happens). I dont know what to do with this PDF file. the manufacturers page is [Link: erms.samsungusa.com] which provides a link to Discreet IR Codes Revised.PDF am i using the wrong program or does someone just need to hold my hand?

ok,i've messed around in the prontoEdit software and understand what to do to create my ccf. _(or some thing like that)file. i just need to know what the heck to do with this PDF

Read the readme file included in makehex.zip



I was unable to get to that first page. Do you have a better link?

Have you tried using the discrete codes from the ir database. I just bought a LNS4052D and they worked for me.

Cheers

Pete

go to Here and select the TVs, LCD tvs and type in Discrete IR Codes revised.PDF (don't hit enter to search, click the search button) it should bring up the link for you. Thanks for the advise on the discrete codes already given for Samsung on the 850, i may have just been stupid. But none the less, i still would like to understand this. its been kickin me in the butt.

I actually found that page myself and typed something similar on a guess after your first link didn't work. When nothing happened I gave up. Just now I tried again with a different browser. I have Sun Java tied to one browser and Microsoft Java tied to the other. Some web pages only work with one or the other. That one only worked with Microsoft Java.

That PDF file is pretty lame. For each function name it has the function number in hex. But it has no overview info: What protocol, what custom code.

Many Samsung TV's uses NECx2 protocol, custom code 0707, which in MakeHex terminology is device=7.7

Try using the NECx2.irp file in MakeHex with that device number. See many other threads for how to use IrPanels to make a CCF file and how to use Universal Browser to drag numbered buttons from the CCF file. You also need to convert the hex numbers in the pdf to decimal, because IrPanels only numbers buttons in decimal.

ok so what your saying is open the NECx2 file inside makehex, change the device code to 7.7, save it, then drop it into the makehex program and let it create a hex file. Open the hex file and copy all the info into the IRPanel window and have it create the file. then, open the universal browser and pull the ircodes create file and then i get the 255 buttons.... correct????i hope

Yes. That is correct.

Actually it's 256 buttons, not 255. Also I had momentarily forgotten that in NECx2 device 7 and device 7.7 are the same thing, so it doesn't matter whether you change it to device=7.7, or device=7 (which is probably the value there already).

I assume you know how to translate the hex number in the PDF (such as 99 for discrete On) into the decimal button number (such as 153 for discrete On).

actally, i am completely new to the whole HEX subject, i didn't learn about it till last night, heard of it.... but didn't know.

if you have the new mx-3000 software you can input the hex code thru the universal browser then save it as a .ccf file then open it with the mx850 software and use the universal browser to access the button that you stored the hex info in

I've seen that feature on the MX-3000 Editor. My problem was finding out the hex for the codes. and figuring out which of my 256 codes is which. I guess johnsfine is telling me that now i have to translate my hex number into a decimal number. hmm.

One easy way to do that is with Windows calculator in view/scientific mode.

Another easy way is with Excel, after enabling the analysis toolpak, using the hex2dec function (but only worthwhile if you have some other reason for organizing the data in Excel).

If you aren't going to use IrPanels, then yet another alternative is to see the section in the MakeHex readme about labeling the functions in hex rather than decimal. But even if the MX editor allows direct pasting of Pronto Hex, I think dragging a numbered button from a CCF is easier than finding, copying, and pasting a hex string from MakeHex's .hex output file to the editor.

For shnakz69 and/or anyone else confused over this detail: The Pronto Hex string itself is of course always in hex. No one is interested in translating THAT to decimal. It is the function number (which in IrPanels becomes the button number) that may need translation. The PDF file lists function numbers in Hex. MakeHex by default labels Pronto Hex strings with function numbers in decimal, and IrPanels only works if the Pronto Hex is labeled with function numbers in decimal.

I sure wish someone would build a version of IrPanels with Hex labels, because more manufacturers publish such PDF files with function numbers in hex than do so with function numbers in decimal.

ok so now when i drop copy the hex file created by makehex into IRPanels and save it, pull it up in my UB it gives me an error "File reading error (LM)" like 5 times before it opens the file. When i click on buttons 1-256 it says in the action list "Learned data" ever seen that before????

Sorry I didn't mention that. All that is what is supposed to happen (except I hope it is 0-255 not 1-256).

I don't know why UB gives a bunch of file read errors, but they never seem to harm the results.

An action list of "Learned data" means that button contains nothing other than a single IR signal in the form UB understands. A typical CCF file you might download from RC would have more interesting (problem) contents on some of its buttons.

UB does not show you any info about the "Learned data". You can drag it to an MX button and test it, but you can't see what it is. You just need to trust that the function number has stayed with the IR from MakeHex through IrPanels to UB.

hey thanks man, i'm gonna get to this and see if it works. Now originally, you said that the PDF was pretty useless except for the hex strings like 99 for Turn on. you also said that most samsung uses the NECx2 file. now if thats not the right one then should i contact the manufaturer for the device numbers and such????
