Sangean HDT-1X Remote Commands

post #1 of 13
Thread Starter 
Hello all. I work for Sangean America and am left on my lonesome to help integrters and others figure out how to program their remotes to use the Sangean HDT-1/HDT-1X remote command codes.

I can program all of the functions with the exception of ones that use what the factory calles a long press. Reportedly the remote that comes with the products simply repeat the same command code for 2 seconds which the tuner then determines to be the long command.

For example: #1 button on remote. When pressed and released will send HEX code 0A recalling the preset #1. Held for 2 seconds will commit the station to memory. To accomplish this the remote repeats HEX code 0A for 2 seconds.

I have been trying to implement this into a Universal Remote Model MX-900 using their supplied MX-900 Editing software to no success. It tells me I can add HEX, but it must be in Pronto format. Any suggestions?

Try this Pronto hex code for the "1" function:

0000 006D 002C 0002 014F 00A7 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 036E 014F 00A7 0015 0D7B

If that works, I'll post the hex codes for the rest of the functions (they are long, so I didn't want to post the whole thing without checking to see if one worked). Test the long press as well. I generated the code above using makehex program with the information I got from here

Unfortunately this did not seem to work, but I don't know if it is because I am not implementing the HEX properly into the MX-900. All it does is recall the station similar to if I simply learned the function. Does this HEX take into account the need to repeat the code for 2 seconds?
post #4 of 13
why not just program a macro to do the hold for 2 seconds?

I have tried to do this only to have it recall the presets twice. . . Go figure.

All this problem would go away if there was simply a learning system that could learn for a whole 2 seconds or a factory that would help me with this. I am in sales.. . .

This is somewhat of a guess, but try this one instead for "1" key:

0000 006D 0000 002C 014F 00A7 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 0D7B

If your device at least responded to the previous code, it is using an Aiwa ir protocol, but there are variations on how the signal is repeated, depending on the device. I'm not familiar with the Aiwa protocol, but the above incorporates the other way the signal might be repeated.

To clarify, the first code did recall the #1 button preset. I said it didn't work only becasue I was testing on the premise that it was for the long press. The code provided above was right in the recall short press.

Here is what the factory told me. This code works of the NEC standard. This is further information from factory:

Please see the attached files of NEC form. That is Leader Code + Custom Code + Data code.
At the 1st time pressing any button on the remote control, the leader code plus is transmitted for 13.5ms, and the custom code+data code to HDT-1/X.
Long press only has leader code, 11.25ms plus to HDT-1X.
The remote control custom code is 13 bits, so HDT-1X doesn't receive any commend when the custom code is not 13 bits. So Leader Code + Custom Code + Data code is only recognized as the 1st pressing, won't save the station.
So the leader code is to distinguish short or long press. And the custom code is to distinguish is the remote it for HDT-1X.


I am also including the data they gave me. I sure hope this works. Many people are waiting for this solution.

So both codes worked for short press, but not for the long press? All the codes I've generated take into account the repeating signal, it's just a matter of how it is repeated.

It's a bit confusing since the data you attached is describing NEC protcol as you said, but the description you posted in red is not quite the same and is closer to the first code I gave you. It may become a little bit of trial and error, but try these for "1" function (they are two different variations, so try the first and if it doesn't work try the second):

0000 006D 002C 0002 014F 00A7 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 0015 0015 0015 0015 0015 0015 003F 0015 0015 0015 003F 0015 0015 0015 003F 0015 003F 0015 003F 0015 003F 0015 036E 014F 0053 0015 0DCF

Ok, to clarify.

Post #2 code worked for short press, not long press.
Post #6 code has not been tested.

I will test Post #6 code and Post #8 code tomorrow and provide feedback.

I included the NEC information because I figured it might help create the printo code. Supposedly there has got to be a way to determine the device codes and information neccessary to create the Pronto commands that work because I don't know of any system that is allowing us to learn the proper long-press code.

From what I gather from the info you posted, it might be a slight variation of the NEC protocol. Try this one as well:

0000 006D 001F 0002 0157 00AC 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0041 0015 0016 0015 0016 0015 0016 0015 0016 0015 0041 0015 0016 0015 0041 0015 0016 0015 0041 0015 0041 0015 0041 0015 0041 0015 0689 0157 0056 0015 0E94

Also, you probably don't have to try the one in post #6. That one was generated before I knew that the repeat signal consist only of the leader code. That one repeats the entire frame for the repeat code (you can certainly try it though, if you have the time).
post #11 of 13
One other thing. Normally, with NEC protocol, there is a custom code specified. I've been assuming that is "1.0" that I originally got from the upgrade file I found over at JP1 remote site, but it would be better if you can verify that with your factory. I guess if one of the codes work, that would also confirm it as well.

Here are the test outcomes:
Post 8 Code 1 Recalls Presets
Post 8 Code 2 does nothing
Post 10 Code does nothing.

I will try and get them to give me the leader codes to determine if they are different.

So here is the good news. . . I gave it a try and learned the commands using the remote instead of the software for the MX-900 and it worked!! I now have the learned commands for the long press of the buttons. The problem is that I don't know how to extract that into a HEX code. . . Any help there?

I've had this Sangean HDT-1x tuner for awhile now, not really being used. Now I have a STR-DN1000 Receiver with a programmable universal remote controller but it has no listing for Sangean tuners... Has anyone successfully programed a Sony remote controller with correct code to operate this Sangean HDT-1x tuner? Sure would be nice if Sangean could publish this info themselves for other manufacture brand remotes to control the Sangean tuner.
