Hi Guys,

This is a toughie. A friend of mine is in the service and is currently in Guam. He has a Dune HD Ultra Media Player. From what I gather it's comparable to a Popcorn Hour Networked Media Tank. Unfortunately he's lost the remote. Since he's so far away I was hoping to just download an upgrade file and load up a remote for him as due to the distance troubleshooting would be a cumbersome process. Unfortunately there's no upgrade file posted. I'm hoping someone out there has one of these remotes they could read for us.

I've done a little research - according to the Dune web site there are two remote versions, an old and a new one. The old remotes work on all the players but the new remotes only work on the new players (seems odd, doesn't it?) and unfortunately it appears the HD Ultra falls in the "old" player category. Dune has posted the hex and stuff but only for the new remotes (I think). What they've posted confuses me - the web site says "All Dune Remotes use NEC protocol. Old and New Dune Remotes have different customer codes: New Dune Remote: 00 BF, Old Dune Remote: 01 BE" but they don't say which version of NEC they use and I don't understand where the "customer codes" come into play. Are they saying the Hex codes are the same just the "customer code" makes them a different protocol variation? The Dune remote control info page is at:

There is an upgrade posted for the new Dune remotes in the file section:

RMDU Remotemaster source file for the Dune BD Prime 3.0.

But the hex codes listed in the Functions tab of Remote Master are not matching up with what's posted on the Dune web page.

Can anyone lend us a hand in getting a remote working for this player?

Thanks!

Steve

There's a popcorn hour upgrade you could try.

The data matches up perfectly, you just need to know how to read it.

The hex codes posted by Dune can be converted into decimal to give you the JP1 device codes and OBCs. However, don't try to compare the Dune hex to the JP1 hex because the NEC1 protocol is LSB-COMP, which means to convert the JP1 hex to decimal you would first need to reverse the binary, then you'd need to complement it.

The "00 BF" customer code means device code 0, sub-device 191.
The "01 BE" customer code means device code 1, sub-device 190.

Looking at the POWER button, as an example, the hex code listed is "00 BF 43 BC"

00 = device code 0
BF = sub-device code 191
43 = OBC 67
BC = the comlement of OBC 67

So, bottom line, you can use the RM upgrade "as is" if you want the new code, or you can change the device code to 1 and the sub-device to 190 if you want the old code.

Here's a 2.0 version of the RM file:

My recommendation would be to load two upgrades into the remote that you send, one in the new format and one in the old format.

That one has a completely different device code, so it probably won't work, but it wouldn't hurt to load it into the remote also, just so your friend has all the options covered.

I thought we were supposed to read the hex backwards (lsb) to get the numbers for a NEC upgrade.

I thought this was device 0, subdevice 253.

Although everyhthing reads better msb.

To convert the DUNE hex to decimal, you do a straight conversion.

To convert JP1 hex for the NEC protocol to decimal, you need to read it backwards *AND* you need to complement it.

Let's look at device code 1.

In Dune hex, that would be 01, simple.

To get the JP1 NEC hex, first, let's create the binary: 0000001
Now, let's run it backwards: 10000000
Now complement it: 01111111
Now convert it to hex: 7F

I dunno what to say! I thought this was going to be some big mountain to climb and in no time that mountain has been leveled!

You guys are the greatest, thanks soooo much!

I'll be sure to post back how it works, but I'm sure it'll work just fine.

THANKS again, take care and have a Merry Christmas and a Happy New Year!

Steve

You're welcome.

After trying the version 2.0 rmdu file in post #p3 of this thread, and not being able to get it to work on my Atlas 1056, I tried the version 3.0 in post #p1 in this thread, and it works. So, if you are looking for a rmdu that works with recent Dune HDI players, use the file in post #p1 in this thread. This working rmdu is set for device 0, which is what you want. Here's another thread on this.
