Dune BD Prime rmdu not working

[wified]

I've been using JP1 remotes for years. Once I found the Atlas 1056, I found the perfect remote. I've added devices over the years, now operating a Vizio TV, Pioneer receiver, AT&T Uverse DVR, Clearplay DVD, and XBox 360. Now I'm trying to add a Dune HD media player, which uses the same remote control as this rmdu:

But I can't get this device to work. Is there anything wrong with this rmdu? It appears to use the NEC 1 protocol, which is one that some of my other devices are using, so that shouldn't be the problem. One thing I notice is that after loading this device, RMIR won't let me chose "Save" - that option is greyed out. I can only chose to "Save As", but when I save that and upload it to my Atlas remote, it doesn't work. Any suggestions on how to resolve this would be appreciated.

Based on this Dune thread, I think you should try both NEC1 device 1 and device 0.

It has been set to device 1. Is there a way to set it to BOTH device 1 AND device 0? Or are you saying that I should just switch it to device 0 and try that? Thanks.

Got it to work. From that thread, there are two different rmdu files there. I was having problems with the one in my first post above. But, downloading this one works:

This one that works is set to device 0. I am using it for the Dune HD Smart B1. So, this is the rmdu file that you need for recent Dune HDI players to work with JP1.

UPDATE: I don't know what difference it makes, but this works better with the device being blank, as opposed to having a 0 entered in as the device. So, that's what's working for me.

I found the following codes for the Dune HD remote, which appear to be a later version of the remote codes than the rmdu above:

I can't figure out how to get these into RM, which I'd like to do, because there are some keys coded that are not in the original rmdu.

Thanks for any help in figuring out how to get these into RM.

In RM, open up the Dune 3.0 upgrade that you're already using. Add additional functions by entering the decimal equivalent of the hexadecimal number shown in the third byte.

For example
SHUFFLE/PIP 00 BF 47 B8

Multiply 4 by 16 and add 7, getting 71. In RM click New, and enter a name such as "Shuffle/PIP" in the Name column, and 71 in the OBC column. Be sure to assign the function to some button using either the Buttons or Layout tab.

I'd try taking the 3rd byte from the left, convert to decimal and enter it in the OBC column. BF in decimal is probably the Device.

In the original rmdu:

Protocol = NEC1
Protocol = 00 5A
Device is blank.
Sub Device = 191
Fixed Data = 20 FF 02

So, the BF = 191, so that's the Sub Device.
What does the last column/byte mean? the "B8" in the above example? Just ignore that when entering into RM?

Thanks so much for your help.

The 4th byte is the binary complement of the 3rd byte. This is a feature of the NEC IR protocol. It serves as a check byte to show that the command was received correctly. B8 and 47 are the complement of each other; RMIR knows this rule, and supplies the 4th byte so you don't have to enter it.

Perfect. Thanks so much.
