Nova Pace 3001 Novabox ,need Help with IR Codes

tsaito · Post by **tsaito** » Fri Dec 25, 2015 6:47 pm

Allan is my mistake the confusion in harmony account.
The remote PACE PVR is a mix from DZS3001 and new nova_xxxx commands.This hapen because the only way to learn the remote was to add commands in existing remote.So from this mix only nova_xxxx work in STB.
About nova_1,nova_2,Nova_3... was just the numbers of the remote 1,2,3...

I redid my decoding of the signals and I didn't get any double negative pairs this time. However, I did discover that there's a checksum bit at the end of the bit string and I need some help deciphering it.

If you look at the binary strings below, you will see that they all start with a "1" bit, which makes sense as it would not be a good idea to start a data string with an OFF bit, and they all end with a "0" bit, which also makes sense as it separates the leadout time. The third column below is the OBC byte, which is in MSB format, and the first of the 2 bits that follow is the checksum. For OBCs 0-9 it is simply the complement of the last OBC bit, but after that, I can't make out the pattern.

I have created an upgrade where the checksum is provided as a data byte, which is not ideal but will do until we can come up with a formula for it. But the generated bin files should work regardless.

Rob,
I believe these are toggle bits rather than checksums. When we look at the 40 distinct signals in the order they were taken, the ICT file shows the bit alternating for successive functions in 37 cases and staying the same in 2. I haven't tried to parse out the IRtrans file in detail, but for the first few signals, the IRtrans decodes are mixed compared to the ICT file. Some have the same toggle/check bit as the ICT file for a given function, but for other functions the bit is complemented.

So assuming tsaito gets your bin file to respond, it may be necessary to change the executor to provide a toggle capability.

Good eyes, making it a toggle rather than a checksum is easier. I will update it.

Post by **The Robman** » Sat Dec 26, 2015 10:37 am

ok, I have updated the upgrade to use a toggle bit. Same URL.

Robman you save my life.
I don't know how to thank you !!!
It respond novabox at two versions of bin file.
I checked one by one the commands.
It is possible to add V- and V+ commands?

Post by **The Robman** » Sat Dec 26, 2015 12:33 pm

the volume commands are in there, but I think Slingbox doesn't include them, so you would need to chose 2 other buttons for them, like page +/- maybe?

tsaito · Post by **tsaito** » Sat Dec 26, 2015 3:40 pm

You are right, Slingbox doesn't include them.

I have to thank you all of you again.

Post by **The Robman** » Sat Dec 26, 2015 4:35 pm

I can program them to different buttons if you tell me which buttons you would like to use.

I went ahead and programmed the vol +/- buttons to page +/- and I programmed MUTE to the WHITE button.

Sorry for the delay. The fix is simple. In order not to break the context, details are given here.

Two issues: 1) In the original file from IrScrutinizer, there are two CR and one LF, and IRScope doesn't like that. 2) the leadouts are given as about 127mS, which causes IRScope to treat the file as one really long macro.

The first one I have fixed. The second one is a bug/design flaw in IrScope. Really. Anyhow, as Dave pointed out, a workaround is simple, and this has been incorporated in the fix too.

I have also learned remote control with IRTrans in case is helpfull for someone.

There is an issue with your .rem file; it does not parse in IrScope. Looking in it, it uses an RO command that is not present in the IrTrans documentation. Regarding this, I have asked in the IrTrans forum. So I would like to ask how you generated that file.

After this update STB does not responde to the commands.This is the previous version that is ok.

.Rem file learned by irtrans server "lern" tool.

I have an issue with remote.If i want to watch channel "303" for example and I press the digit 3,0 and 3, sometimes in display i saw "3003" sometimes "03" sometimes the correct number 303.The same problem appear both to browser and slingbox application.
Is there any idea for that?

3FG · Post by **3FG** » Sun Jan 10, 2016 6:53 pm

We guessed about the Nova IR protocol, and Rob's bin file sends our best guess as to the toggle nature. However, the signals have the oddity that the very last bit sent is always zero, and we don't understand the point of doing that. If you can learn a few signals (preferably using the Raw mode of IRTrans), we should be able to figure this out.

Please learn buttons 1, 2, and 3. Learn while holding the button so that we get several frames of IR. Release the button, wait, and then learn the button again while holding the button. Do the sequence of learn and wait 5 times for each of the 1, 2, and 3 buttons.

I prefer the Raw mode, so that IRTrans isn't "helping" us by classifying the burst pairs.
