JP1 Remotes

I programed the 7740 now completly and found everything is working fine.

Thanks a lot to The Robman

Here is what I did:
1. I removed all protocols and devices from the 7740 and ended up with http://www.zweckstetter.de/test7740_reseted.ir
2. I opened a fresh RemoteMaster, and loaded the http://www.zweckstetter.de/vrc_on_tv_test.rmdu
3. I added the device update Upgrade Code 0 = 06 42 (TV/1602 ...

I got the distinct impression that seilae just dumped the upgrade from the currenty use an URC-7560 into this urc-7740 and that's why the buttons are coming out in some kind of decent order. I tried to find where I got that impression, but its too much reading for me.
I asked, if I can use the ...

OK, now i can control the vcr with the modes tv, vcr and sat

I did create 3 upgrades. The test with the VCR upgrade did not show any mismatch.
Next I will do an upgrade for the tv to test the VPT.

I will give it a try with a real update for my vcr to test it.

The VPT in the ir.exe displayed correctly.

The 7560 tells me that the button codes are not at the right place. What puzzels me is,that the button "6" is a key move in der update and contains the code from ...

here are the diffs when disabling vpt per device

Finaly I succeded in prying it open (nearly broke it)

There seem to be more than one version of the 7740. Mine has got an jp1. On the back side is the number 3131.2 , not 3134.2

S00 MAGIC
S01 POWER
S02 TV
S03 VCR
S04 DVD
S05 SAT
S06 1
S07 2
S10 3
S11 4
