I have been following some threads on the site that deal with hex codes , i also found hex codes for my Nakamichi CR-7E (of which i do not have the IR remote). My question is how do i use the hex code information and what kind of remote and probably software do i need to make my deck remote operated? I am not so familiar with the literature behind this task and any info provided by the knowledgible members will be much appreciated. at the end of the day i will know if i can afford doing this myself or i will need experts help...
The remotes that i have are: One4all urc 9960 (us edition) Sony Rm-AV2000, and one4all URC 7562, which i believe wont do any good.....I probably need to go for a pronto or something similar.....

If you get a JP1 cable, you certainly can use those codes with your 7562. I think the 9960 requires a "pogo adapter" to be compatible with a JP1 cable, but then it also could use the codes.

Both of those can use a lot of such codes even without a JP1 cable, but it depends on the codes.

Post a few of the codes (or better a link to the file containing them if it is online). I can tell you whether/how the 9960 can use them without a JP1 cable. I might not have enough info on the 7562 to answer the same question for that.

Hi Johnsfine and thank you for your swift reply

Actually the link is within the remote central site only difference with my Nakamichi model is that the CR7a is for USA and the CR7e (mine) is for the European model, which i believe will not be a problem (as far as compatibility concerns). In any case this is something to check when i will know how....

So this is the link:

I have to admitt i do not know what a JP1 cable is and i hope i will not need one, but if i do i will have to ask you to pass some info on that too......

I will be looking forward to hearing from you

I decoded (see below) a couple of those signals and looked them up in file I got from Rob (see below). That indicates the two setup codes that could generate those signals are CD/0147 and Tape/0218. But it also indicates that neither of those those setup codes are built-in on either the 9960 or the 7562.

The easiest option may be updating by .wav file. I believe .wav files for the 7562 are available from an OFA website. I believe .wav files for the 9960 are only available from OFA customer support over the phone (to the USA). I expect phone calls to the USA wouldn't be your best choice. For more info about getting .wav files search the forum at
[Link: remotecentral.com] or ask some questions there.

It is also possible to make your own .wav file for either the 9960 or the 7562 using the free JP1 software available from Rob's website at [Link: hifi-remote.com]
A .wav file you make that way would be customized to your specific needs and thus much better than an official .wav file from OFA. But there is a fair amount of learning required to know how to use the JP1 software to produce a .wav file.

A .wav file is loaded into the remote by inductive pickup from a telephone handset or a PC speaker. No extra hardware nor physical connection is required (but on some telephone handsets and some PC speakers it won't work because they produce too little magnetic field. It isn't the sound that carries the info. It is the magnetic field the speaker generates in the process of producing the sound).

An upgrade file created with the JP1 software is a lot easier to load directly into the remote by JP1 cable than to transform to .wav and load through the PC speaker. But that way requires buying or building the cable (see Rob's website).

However you do it, you'll need the info from decoding those Pronto Hex string you find. To do that you need DecodeIr.dll and the JP1 version of IrTool.exe
[Link: john.fine.home.comcast.net]
[Link: remotecentral.com]

Run IrTool with DecodeIr in the same directory, then copy/paste each Pronto Hex string from that page you linked into IrTool and press Decode. A pop up dialog should appear with the decode info. For example the STOP command decodes as: NEC1, device=103, OBC=17, EFC=121.

If you get one of those two setup codes I mentioned above, NEC1 device=103 is built into the setup code. You can use the EFC numbers to program specific functions to specific buttons (some of the buttons you want might already be the default in the setup code). If you don't know how to use EFC numbers, it is explained in many threads in that rc-one4all forum I mentioned. But the EFC numbers are useless unless you have a compatible setup code, which I think requires update by either .wav file or JP1 cable.

If you use the JP1 software to produce a file you need to input the NEC1 and 103 to the setup sheet and use either OBC or EFC number to define each function (EFC number is an encrypted form of OBC number that OneForAll uses to try to hide information, but their encryption was cracked long ago).

Hi again and thank you for your reply and your time spend to help me with this issue

I realize this is not an easy task despite the very informative and simple written advice you have forwarded me..I need to sit down and do some serious readind before any attempt can take place for solving the problem. Both remotes are concidered for use since they have JP1 socket on the back (7562 looks more easy to hook up ) ,which i will have to purchase, but in any case i would prefer to follow your advice and try the option with the cable and software instead of using the magnetic field option.
My only fear is if during the process i make a mistake that would be impossible to "undo" and bring the remote to a BLR (beyond local repair) state!

As you can realize from my writings i am not at all familiar with the process and any link for advice on "how to" would be very wellcomed!
Thanks again!

That is almost impossible. The remote includes a factory reset operation (command 981) that cleans the eeprom back to the condition of a new unit. So a software type mistake could cost you your leaned signals and existing keymoves and macros etc., but it can't leave the remote worse off than before you initially programmed it. Hopefully you will understand the IR.exe program well enough to start by saving your eeprom image (with all your manual programming) in a .ir file before you start experimenting. But if you don't, that certainly isn't beyond local repair. You programmed whatever Macros etc. you have once so you could again (and that's easier to do by JP1 than the way you did it originally).

I try real hard to plug the JP1 connector correctly every time (it fits backwards and in most remotes fits offset by one position in any direction). But other experts claim that plugged in wrong it simply won't work; It won't do any permanent harm. Lots of user experience seems to back up that claim.
