I have been trying to find some discrete codes for some Dell 42inch TV. It has been very difficult to find hardly any information on Dell IR commands.

Just from playing around I have got a few Phillip IR commands to work.

Input toggle
5000 0000 0000 0001 0000 0038
vol down
5000 0000 0000 0001 0000 0011
5000 0000 0000 0001 0000 0051
vol up
5000 0000 0000 0001 0000 0010
Menu
5000 0000 0000 0001 0000 0012
Power Toggle
5000 0000 0000 0001 0000 000C


I have tried a lot of the other IR discrete commands offered by Philips with no success. I even tried the 2004_2005 TV Discrete Power_Inputs_Formatting.pcf and none of these worked. The ones above are the only ones I can get to work. I really need the discrete input commands.

The weird thing is I found the power off discrete command by doing a search under brands on the Pronto. What is weirder when I hook up to the software and Hit Test IR it is a power toggle.

Any help would be helpful!

Philips TV codes can be hit or miss. My experience is that one command for one TV may be a different command for another. I have run across a similar situation where a discrete power off command that worked for a particular plasma was a toggle command on another set.

Can you post a couple of cleanly learned codes from the native remote in your reply?

This is very surprising. You got RC5 signals to work for a device whose original remote sends MCE signals. I haven't heard of that before.

Despite those RC5 signals working, I'd expect discretes, if there are any, to be MCE signals.


I don't follow that at all. Do you really have a power off discrete?

An MCE signal (or an RC5 signal) includes a "toggle bit". Misunderstanding the behavior of a toggle bit often makes people think they've found a discrete command when they really have a malfunction in a toggle command. More organised testing then proves that the "discrete" command cannot be made to act reliably (because it never really was a discrete command).

If you are correct about the toggle bit issue with the discrete vs toggle scenario I described in my prior post, Then Philips must have it wrong. The codes I have are straight from their own published CCF.

Yeah I have thought about the toggle bit. I have waited over night and came in and hit the off button, I have hit it about 75 times not being able to turn it on. I can not get it to turn on. I am not 100% sure if it is a real discrete command or not, but it will only turn it off at this point with the remote unless i use the software.

Is there any devices I should try for MCE discrete commands?

If you look on here you can see that it says to use Philips, but isnt that RC6?

Let me know, thanks

Those Pronto Hex samples you posted decode as MCE device=0.28 functions 54, 1, 7, and 2.

Neither that device number nor the function numbers match those in any CCF file I have for MCE TV's.

You could use MakeHex/IrPanels to generate all 256 possible commands for MCE:0.28 and test them and see what they do. First read warning at:

RC5 is a Philips protocol used by many Philips TV's.

RC6 is both a family of related Philips protocols and a specific protocol. That specific RC6 protocol is used by other Philips TV's (and some Philips TV's accept both RC5 and RC6 commands).

The MCE protocol is a Microsoft IR protocol that is in the Philips RC6 family of IR protocols. MCE is used by several brands of TV, but so far as I know, not by any Philips TV's.

Dell may have programmed this TV to support a second IR code set in order to make it usable with universal remotes, most of which don't support MCE.

Here is a document i got from Dell about IR Discrete codes. This is for the w4200C but i do not think it works with mine (w4200ed). I figured the protocol would be close to this? Can you make any since of this?

I am looking at the Hex generator. Is there a post that could walk me through generating all 256 options? I do not know how to create a .IRP

I think i got it figure out. Would this be the correct mce.irp?

What do you see different about this one, compared to the other ones?

Also, ont he ccf file all the buttons when I click on them just say delay 0.10. Is this correct? Can I not see the ir command or did i do something wrong.

Thanks for your support.

Using the dell.irp i can do the basic functions, no discrete.

If i use this code on the remote it only turns off the tv. When I use the program I get the toggle?

Where did you get all that from?

This is the correct mce.irp

Device=0.28
Function=0..255
Define M=6
Define T=0
Frequency=36000
Time Base=444
Message Time=106m
Zero=-1,1
One=1,-1
First Bit=MSB
Form=;6,-2,1:1,M:3,-2,2,128:8,S:8,T:1,D:7,F:8


I hadn't noticed before that C was defined in my copy of mce.irp. It doesn't do anything. It must have been accidentally left over from some earlier related .irp file that I used as a basis for this one. I just removed it from my own copy.

But why did you change M and T?

M has to be 6 or the result won't be MCE protocol.

T can only be 0 or 1. That is the toggle bit. Depending on how you use the results, you may need both versions (T=0 and T=1) of each command. But for checking for discretes I think either version should be OK.

Same protocol and device. This one is function 41.


You mean the CCF from IrPanels? Or what CCF do you mean?

IrPanels has a CCF file without any IR signals that it uses as a template for creating the new CCF. It merges the IR signals with that and writes the result to a DIFFERENT ccf file. Did you not really operate Irpanels? Or did you just look at the wrong ccf file when it was done?

I had forgotten about Dell.irp

Obviously I HAVE seen the MCE signals with device=0.28 before, even though I couldn't find examples in my fille collection today. In fact I must have seen those as the first non Microsoft brand of MCE I ever saw, so I created Dell.irp before I created MCE.irp

I think you get the same results from Dell.irp with device=0 that you get from MCE.irp with Device=0.28



That is function 76 (generated with T=0)

I don't know why it behaves differently when used those two ways. What does function 76 generated with T=1 do? More imprtantly, if you put both of those on the remote on two different buttons and use them alternately, what do they do?
