JP1 Remotes

I am new to JP1 so when I posted my first time a few days ago I did not know the rules exactly. Hopefully I am a little better now in speaking the language of JP1.

First. Let me update where I stand:

1. Device: Epson ELP 7250 projector
2. Type of device: LCD projector
3. Year: 2001
4. JP1/UEI Remote model: 15-2117/2116
5. Do you have a JP1 cable? Yes
6. Still have original remote? No
7. Checked the file section? Yes
8. Checked Pronto file section (at R/C)? Yes
9. Partially working setup code? Yes
10. Learning remote question? No

I downloaded your jon_armstrong's TXT file from http://www.hifi-remote.com/forums/viewtopic.php?t=3141 and try it with KM+IR. It is not working. Then I noticed the remote in the KM file is for 1994. After change it to 2117/2116. It works partially: the remote was able to turn on the projector but the LED on remote keep on. I have to pull the battery out to stop it. The same situation occurs for the Menu key.

I have tried the all files in JP1 forum related to Epson projector but nothing works(like 73xc, TW20). I also wondering whether it is possible to import the Pronto Hex into Leaned Signal. The 7250 Pronto Hex in RC can't be recognized by IRTool. Since I do not have the original remote, I can't try all the tricks mentioned here. I try to buy one in eBay but was outbided in last second.

Thanks in advance.

Do you have a link to the 7250 Pronto Hex? My guess is that you have extra line breaks in the Pronto Hex code when you cut-n-pasted into IRTool.

The other thread mentions that the cursor keys will require a different protocol/device upgrade and I think it was never finished.

You'll have to run 'decodeccf 52 x emp710.ccf' in order to get the full Pronto Hex to cut-n-paste into IRtool.exe.

Ahh, I'd never used the decodeCCF command line. I see that this makes a lot more sense with those timing data.

52 = The first argument when there is more than one, is the number of words of raw Pronto hex to display when no decode is found.

x = timing data.

I pasted this into IRTool and got a some information that I sure don't know how to handle. I'm used to the OBC and EFC to pop up. What I'm seeing here is what I'd normally see if I don't have decodeIR.DLL in the folder.

Jon Armstrong had described what he saw in the Aurora IR library as a Quad, I see that this EMP710 has 4 timings pairs 327-954, 327-408, 327-681, 327-1226 is that what he meant by this being a quad?

I also see that half of these signals for the EMP710 decoded as RC5. What ususally happens with these?

BTW: I really don't think this is what you meant when you told me to start with a simpiler data set. Wink

Here is another thread about 4part decodes.

But I'm still trying to just look at this and get a sense of the whole pattern. Somewhere in all this there is a check bit. Yeah right!

Boy I wish I could let go of this! Some of the keys decode as RC5. Is that a clue? Are some signals timed?

Should I be adding all the off times looking for something here?

I think if you knew enough this could be fun.

Thanks.

Unziping VickyG2003's zip file I got 'Epson1.ir' and 'Ronin 17 Apr 03.ccf' not the EMP710.ccf as mentioned. Copy-n-paste the learned code to 2116 and try it. The projector would turn on but the remote won't lock up either.

Tried doing DecodeCCF in DOS as suggested:
decodeccf 52 x "Robin 17 Apr 03.ccf"
Don't know how to use the decoded CCF file. Any reference?

I also got a RC1475501/00MB remote from a friend today. Will try it once I got time to build JP1.x cable.

The .TXT file that decodeccf is best read in a spreadsheet that separates things into columns. It'll show you a pronto hex line that can be cut-n-pasted into IRtool.

Have we even determined that the 8820 learned signals replicate the Pronto hex signals?

I didn't read this thread carefully, nor download any of the files. Just making a comment that might be obvious anyway (I never know which aspects will be obvious to others).

Thanks John. Nothing is obvious to me. But looking at it, I was certain that there was something wrong with the the signals that I learned. I wasn't suspecting the learn process, I thought there might have been something wrong with the KM file that I changed and downloaded. Now I know its the learn.

Sorry. Ths following was wrong. The projector would NOT be turned on.

Rob, it looks like your EMP835 protocol might help with the Epson 710/820.

The EMP820 uses the same type of signal as the EMP710, not the type that we are seeing in the EMP830.
Epson powerlite Emp820 and Emp710

TV has the 820 learn imports, AUX has the EMP710 learn imports.

Could not import Power Off confirm from the EMP820
could not import Power Toggle, Freeze, Resize or Up from the EMP710 files.

Can you see any pattern in these, or should I just make a 6 command byte signal?
