I need to convert the Pronto hex codes for ReplayTV discretes to the corresponding EFC codes. I tried the CCF2EFC program found on Yahoo jp1 group, but that requires an entire CCF file. How would I go about converting just the hex code to the EFC for eventual input into my MX-700? (I'll figure out how to put the codes into my 8811, I've got the programs for that.)

Thanks.

Stan,

There are already files for device upgrades including all the ReplayTV commands at the JP1 site. Rob Crowe, the force behind www.hifi-remote.com and the Jp1 group is also a big ReplayTV fan so I think that there are also commands there that probably can't be found elsewhere.

Replay uses an IR protocol called RC6a that will take two bytes commands in an OFA remote. So simply knowing the EFC won't work like the single byte commands. Hence, to get a discrete power command for Replay into the 8811 will require a JP1 cable.

Thanks Jon!

I'd still like to know how to convert pronto hex codes to efcs. Is this even possible?

Thanks,
Derek

Derek,

The only direct way is to use John Fine's ccf2efc program. The most recent version is in the files section a the JP1 Yahoo group.

Jon,

I tried ccf2efc, but it appears that this program only works with entire ccf files. How do I convert codes for single commands to efc format?

For example, how would I use the follwing with my 8811 remote:

0000 0070 0000 0032 0080 0040 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0010 0010 0030 0010 0010 0010 0010 0010 0010 0010 0030 0010 0030 0010 0030 0010 0010 0010 0030 0010 0030 0010 0030 0010 0010 0010 0010 0010 0ac3

Derek,

It's Panasonic protocol device 176 (DVD_0490) command 139

What does it do? It is not on any list of commands that I have.

To answer your question about how to decode Pronto hex itself:

It is either paste the command into Pronto edit and save as a ccf file. Then ccf2efc must know that protocol to decode it. If not you would have to decode it manually to get an EFC. To decode manually you could follow the following steps:

1. Read Barry Gordon's article on how to decode pronto hex.

2. Download Barry Gordon's program GenIRDB and read its documentation on IR protocols. Download John Fine's MakeHex (it has the protocols definitions that his program ccf2efc decodes) -- It also helps to know

3. Study the library that comes with GenIRDB and the Panasonic protocol file.

4. Decode the file (knowing the protocol -- easier; not knowing the protocol with only one command --very hard to impossible)

5. Go the the www.hifi-remote.com and read about OBC to EFC conversions. Join and read the read me files at JP1 and anthing else there. Download devices.xls that has a cross reference between Protocol/Device combinations and OFA Setup codes.

To say the least, for a few commands manual decoding is a lot of work but in some cases there may be no alternative.

Jon,

Thanks a lot for your help. This command is an 8 second quick replay for panasonic dvd players. I'm hoping it will work on the denon dvd-1600.
Thanks again,
Derek
