JP1 Remotes

OK for starters, the target device is a HAVA using PL, same difference as regards SlingBox.

Need a code for Handan DVB-C 5000 used in Finland. Using my UEI JP1 learning remote etc. I have captured the IR file (located here) but it has a bit of a discrepancy when it comes to transferring this info to RemoteMaster. I can make the Hex and EFC agree with what IR shows, but not all 3 Hex, EFC and OBC. The only way I could make them agree was to select Streamzap 57 kHz in RM, but that didn't work ultimately either.

I've also tried the Handan CDC-7000 code to be found here. But when I load that into RM, I get a different correspondence of the HEX, EFC and OBC between IR and RM.

Last question for now, in the posted CDC-7000 code there are two different files posted, one for Device #34 and another for device #35. Some comment is made about compiling these separately and then bringing them together using a Key Move. I noticed in IR that most keys are using dev #34 and a few are using dev #35. Is this "Key Move" thing possible on Slingbox/HAVA PL?

Thanks Rob.

I noticed that this one too, when loaded into RM, the values don't match up with what was reported by IR. I haven't confirmed with the customer that this code works either. In the meantime, can you elaborate on what you did here (as the need may arise again).

Thanks,

DL

Generally speaking, you don't need to try and match up all the different values (ie, OBC, EFC, hex, etc), the main one that should match up is the OBC column.

Anytime a protocol uses less than 8 bits for it's OBC, there's the chance that different EFC/hex values will create the same signal. Furthermore, the spare bits will often get used as an index to select different device code data, which is how the original Streamzap executor was set up.

DecodeIR, the program that does the decodes for IR.exe, doesn't know how the final upgrade is going to be set up, it just knows about the one signal that it's looking at.

In this case, I wrote a new executor for your signals. Instead of beaking the signal down into an 8-bit device code and a 6-bit command code, I changed it to a 6-bit device code and an 8-bit command code. I did this so that all of the buttons would end up using the same device code (you noticed that some used device code 34 and some used 35 under the old scheme).

So, the codes in my upgrade file won't match anything that was reported by decodeIR, but if you convert the learned signals into binary and compare that to the hex codes in my upgrade, you will find that they do match.
