I pasted the codes into pronto edit on some buttons using add Ir code. Saved the ccf file and ran ccf2efc and did not get the correct efc's. I am not sure what I am doing wrong.

dave

double click on button,
click on set ir,
click on view ir,
paste the code in the ir code section

That is what I did exactly. It did program the button. I was able to locate the programming of the code using cf2efc.The problem was when I dumped the ccf the efc code was wrong for my unit. I am not trying to run the pronto I am programming the mx-500. I am just using the pronto file to get the efc.

Dave,

The best way to find EFC's from true commands is to start at Rob Crowe's www.hifi-remote.com the unofficial OFA site. The relationship between true Protocol/Device (NEC1:122) relationship to OFA setup code (Audio_0176) has been deduced by people decoding the IR signals.

hifi-remote has links to the JP1 Yahoo group and many tools are in their files section. There are EFC conversion tables in the advanced codes section of hifi-remote. There are four cases there and you want LSB complement.

EFC's do have an algorithmic relationship to command or function code (known there as OBC) but it is just easier to use the tables. John Fine who wrote ccf2efc and MakeHex figured it out.

In the case of Onkyo, that uses the NEC1 protocol, the device code and command codes are 8-bits as are EFC's, so there is a "one-to-one" correspondence between them. In contrast, Sony uses 7-bit command codes and the OFA remotes use the 8th bit to call alternate devices. So for Sony there are two EFC's for each command. One calls device A the other device B.

A good example is TV_0000 the major TV code for all North American Sony TV's. TV_0000 contains Device 1 and Device 164 and depending on the EFC you can call any of the 128 commands for either device.

I think you will end up buying or making the JP1 cable and I highly recommend that since it opens up a whole new realm of capabilities with your 8811. For example you can learn a command and IR.exe (the freeware program that handles the interface between the remote and the PC) can read the learned IR signal and return device code and true command code (called OBC in the OFA world) in fact that capability is based of ccf2efc.

So you can learn commands from you OEM remote and create device upgrades to create just about anything. We have controlled fans, lighting, obscure electronic equipment, video switchers, etc.

The other benefit is that there are many device upgrades in the JP1 files section to solve many of the aggravating problems of no discrete commands on OEM remotes to the use of some fairly complex signals to control things like Sony DSP fields.

Your recommendation is where I am heading. I have the cable and the software and will begin learning the process. I am able to do most things I want to do now but if I can access the extended Ir codes that yamaha lists I can get more discretes. These extended codes use a different device code and are not on the remote so my only way I know to do this is to create a new device type with JP1 and enter the obc's I have and try them out.

Thanks again
Dave

Dave,

You are correct and once you find out how easy it is compared to remembering a bunch of button pushing procedures (and that you can save your various configurations)you'll be glad you did.

BTW, Key Map Master, the tool that creates device upgrades, will do the OBC to EFC conversions as I think you may have already figured out.

How do you use the codes listed on the Yamaha site be input into Mx-500 using URC or Radio Shack remotes. I have managed to input 4 digit numerical codes for my Sony TV but I am stumped by these codes. Do they need to be converted to numerical codes.

So what is the difference between Yamahas standard and extended codes?

Can I use both the same way?

I just purchased a OFA 8811 w/JP1 cable and a HTM MX-500, and have started to get the hang of the KM spreadsheet and IR, but I have only been using the standard codes found at Yamaha. Can I also use the extended codes?

The way I have been doing this, is I printed the standard codes from Yamaha, and then converted all of the codes to EFC with the calculator function in IR, and then I entered them into the functions page of the KM spreadsheet, assigned them to buttons, cut and pasted into IR, and uploaded this into my remote.

Also - I have a ReplayTV 5040, which has a JP1 connector. Can I use IR to program the volume buttons to control my Yamaha receivers volume?

Thanks,
Mike
