I'm tryng to set up my MX-500 to control my new Samsung LNT 4671 TV.
I also have a OFA and the JP1 cable and have downloaded the supporting software,
Ir.exe, KM, etc. I have also found the Samsung Pronto codes posted here by
Jason. Finally, I have read the documentation for the software provided by Rob
and others.

Now, to my questions:

1. How do I download the code sequences in Jason's postings? Copy and past into a local text file? Paste it into DecodeCFF?

2. After DecodeCFF has processed the data and I open the produced file with Excel, what next? IOW, how do I get it into KM? Or, perhaps I don't need to go through KM ant all, just somehoe import it into IR.exe?

3. Once I get the setup into OFA, do I do a key-by-key teaching of the MX-500?

Any pointers greatly appreciated?

TIA

1) DecodeCCF is just for CCF files. You could paste codes into a CCF file using ProntoEdit, then use DecodeCCF. But that is the long way around. You might find someone has already built a CCF file with the desired info. If not, then:

Use the JP1 version of IrTool with DecodeIR.dll
[Link: remotecentral.com]
[Link: john.fine.home.comcast.net]

2) The decode will give you a protocol name, a device number, a subdevice number (maybe), an OBC number and an EFC number.
IrTool gives you a popup with that info for one singla at a time after you paste in the Pronto Hex. To use KM, you need to manually type the protocol name, device and subdevice, probably just once, into KM's setup sheet. (Select OBC mode) Then manually type the OBC number of each funtion into the functions sheet.
From Excel reading decodeCCF output, you may be able to copy/paste the whole column for OBC numbers at once into KM, but you'd need to know Excel pretty well for that (I think KM needs a special paste).

If you know a compatible setup code number. You don't really need KM at all. You could define KeyMoves based on the EFC numbers.

3) What's the problem? I assume you know how to make the MX-500 learn. You know how to press keys on the OFA.

OK, I found a CFF file sam-tv-lnt3253h.zip submittet by Rhonda Geisler
in July 2007. I ran DecodeCCF on it and it seemed to work. Now puzzling
over how to use it. (See below)



I am very familar with Excel, so that's not a problem. What I don't understand is
what to do, if anything, with all the other stuff in the decodeCCF output. For example, at the far right of the Excel worksheet is a very long string of number pairs:
4522-4496 552-1709 552-1709 552-1709 552-578 552-578 552-578 552-578 552-578 552-1709 552-1709 552-1709 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-578 552-1709 552-1709 552-1709 552-1709 552-1709 552-1709 552-1709 552-1709 552-43992
My motivation here is the EFCs alone don't work. For example, if I point the OFA at the set
and punch:

TV
Set (short press)
0-0-1

the set doesn't go on, even though the subject decoded CCF file says that's the
EFC. I'm thinking that my LN-T4671F needs a different set of pulse width hex codes,
and that's what's in the right-most column of the decoded CCF file. Is this right or wrong? If I'm right, how do I get that data into KM, IR.exe, or whatever?


Thanks in advance for your help.

Most of it you don't do anything with. DecodeCCF doesn't know what you intend to do with the results. So it dumps lots of info.


That is raw timing info for expert use in diagnosing some kinds of problem decodes. Even experts normally ignore that part.


An EFC number works only in the context of a compatible setup code. So before testing a setup code, you need to have selected a device key, and before that you need to have programmed a compatible setup code number onto that device key.

DecodeCCF does NOT have any database of setup code numbers, so it does not tell you the setup code number. DecodeCCF tells you the protocol name, device number and subdevice number. There are files at hifi-remote in which you can look up an OFA model and protocol, device and subdevice to find the setup code numbers if they exist. In both the hifi-remote forums and the OFA forum here at RC, the experts are pretty friendly about doing that lookup for you if you post OFA model and protocol, device and subdevice.

Since you have a JP1 cable, you don't need to be limited to built-in setup codes. You can create a new one with and protocol, device and subdevice you like.


Probably wrong. I don't know whether the LN-T4671F understands the discrete codes you found elsewhere. Samsung is very inconsistent about which models (or even which firmware revs of one model) understand which commands.

I don't know whether you tested with a compatible setup code or whether you sent a totally unrelated signal by using the right EFC number but with a wrong protocol, device or subdevice.


KM doesn't take raw timing info. No JP1 tools do, and there is almost never any need to (and this certainly isn't such a case). hifi-remote has good help documents for using protocol, device and subdevice together with pairs of function name and either OBC or EFC.

I think I've about solved my problems... with more than a little help from these forum. I'll summarize what I've learned so someone else might benefit.

Turns out that many of the EFC codes extracted from the CCF file sam-tv-lnt3253h.zip submittet by Rhonda Geisler in July 2007 do work for my LN-T4671F after all, as Johnsfine thought. I though they didn't because I was not clear on some details of using the OFA remote to test the codes. At first I was using the simple procedure:
Press device key (TV)
Short press of Setup
Enter 3-digit EFC
Watch for expected result on the TV

However, one first needs to have a correct setup code associated with TV. Apparently I missed that point. Another error was trying to program the codes and assign them to keys on the OFA for later "training" of the MX-500. The mistake I was making was trying to assign them to numeric keys, e.g., 1 was to be Power On and 3 Power Off. Turns out that when numeric keys are used you have to press them TWICE after entering the 3-digit EFC. It's probably better to not use numeric keys in the first place, since the L1, L2, L3, & L4 keys are just as convenient.

Once I got past there misunderstandings things started falling into place. I quickly got the discrete on/off functions working on the OFA and learned them on the MX-500. Then I began finding the discretes for the inputs. The codes from the above mentioned CCF file were not perfect, but a little playing around and I had all that I needed.

So here are the discrete codes for the LN-T4671F that can't be learned from the Samsung remote:
P-On: 001
P-Off: 253
HDMI1: 081
HDMI2: 014
HDMI3: 175
COMP1: 190
COMP2: 061
SVID1:192
SVID2: 080
Ant1(Air): 251

If you need codes that I don't list here you can probably dig them out of the CCF file like I did. Download the file and process it with DecodeCCF. Open it with Excel or like program so the columns line up. Look for names in the Keys column that look like they might be the ones you need and test them with the OFA. If one doesn't work, look for another one of the same name, as I found some duplicates, e.g. HDMI2 appears twice with two different codes! Don't know why.

BTW, the setup code I used on the OFA is 0060 and for the MX-500 101.

One final thing. When programming your macros on the MX-500 be aware that the Samsung LN-T4671F taks a LONG time to power up. To set the input you may have to put in the switch to SVID1 or whatever 2 or three times, separated by 3 second pauses to get it to switch...
