Hello all, I have a LC-37GD4U on which no discrete inputs I can find on the web work for inputs 1-4. All the various ones posted on remote central in the discrete hex code area or within this forum DO NOT work for these inputs. Discrete On/Off, PC Input(Input 5 DVI), and Antenna a or antenna b , these commands do work. I am using a RTI T1 in this application in standalone mode, but I do also have a RTI T3 and RP6 in my basement. I was hoping to avoid having to run a serial cable up to the bedroom that this TV is in, as I do have serial commands available for this set for those inputs. The setup in that room is pretty simple and if only I had discrete IR inputs I would be very happy. I have tried every variation of code for RPTV's,Projectors,Plasma's or LCD's that RTI has in there database and no luck either. Hopefully one of you IR experts here can help me. RTI's IR database program does allow me to modify the carrier frequency, but I don't think that is the fix.

I have been trying to find discrete codes for this for longer than i
care to think and decided to give it another crack, so far no luck. Have you managed to make any progress?

At the moment i am thinking of going the IR-to-RS232 route, but
most of the options i have seen are complete overkill (not to mention
$$).

Take a look at the codes in:http://www.hifi-remote.com/forums/dload.php?action=file&file_id=1644> sfhub's posted code. I've just used them as a basis of working out discretes for a new Sharp D92 (which has 7 external inputs).

Note that you DO have to use the Sharp combo protocol, and merely entering in the EFC values for the basic Sharp protocol will NOT work (at least with the codes provided by sfhub).

That sounds like you are saying you found the discrete input 6 and 7 commands. I can't see how you might extrapolate those from that file, in which

input 1 = 1:53
input 2 = 1:54
input 3 = 1:55
input 4 = 1:205
input 5 = 17:76

If you can guess 6 and 7 based on that, you're seeing something I'm missing.

So if you did find 6 and 7, what were they?


That part assumes you're using a UEI remote (OneForAll or related models of other brands). I wouldn't guess the other people posting/reading this thread are mostly using UEI remotes.

I didn't mean to say I extrapolated from just reading. I did an exhaustive search of the subdevice 1 and 17 pages using a programmable remote to look for useful discretes. It was the "hint" from sfhub that these pages were of value that caused me to look there... and find some useful things (on my Sharp LC-52D92U).

I'm using the following OBC codes:

input 1 select 053:1
input 2 select 054:1
input 3 select 055:1
input 4 select 205:1
input 5 select 076:17
input 6 select 080:17
input 7 select 149:17

On my D92, I noticed that the following also works (again, looking at OBC codes):

input 1 select 050:1
input 2 select 051:1
input 3 select 052:1
input 4 select 211:1

Hope that helps,

Jim

p.s., I haven't searched the device 30 space (which is also referenced by sfhub), as all the keys he exposed in that space seemed VERY specific to his model (re: recording onto pc-card, etc.), and I have no similar functionality.

I was sadly unable to find a discrete for selecting the TV tuner as the input source :-(. Sfhub called this "TV digital" in his function map, but the corresponding code does not cause any response from my D92. As a hack workaround, I'm using "channel up" as a discrete to select the TV tuner as input. It (sadly) has a side effect of changing the channel iff I'm already using the tuner as input... but it is not bad (I can even try to track state to avoid the minor side effect). If anyone has other suggestions where I might look to find this tuner-input selecting discrete... I'd be willing to do some searching.

As an word of warning for other folks that go hunting for useful codes via an exhaustive (exhausting) search the way I did....

On my D92, I learned the hard way to avoid the OBC code:

evil K mode 119:1

This code puts up a 2 inch white K to the left side of the screen, emblazoned on a 3 inch green square, with a thin white border. It appears to be some test mode, which I (almost) couldn't get out of. I tried power cycle (by switch, and by unplugging), but could not get rid of the darn K (leading me to the name "evil K mode"). This mode also left my TV with only three volume setting; mute/middle/max.

Eventually my exhaustive search uncovered:

industrial initialization 235:1

which did a major reset that got rid of the K. It left the TV stuck in a giant "industrial initialization success" screen (with background audio, but no video playing). This "success" mode could only be exited by unplugging the TV, and upon power-up, I was given the EZ-Setup (of a new TV) to run. Whew!

It sure scared the heck out me.... so I'm just mentioning this in case someone else doing a search gets "stuck."

There might be some hardware reset hole hiding on my D92... but I couldn't find it... so the above reset code was VERY helpful.

Ok, I am not an IR expert, and am having trouble piecing this string together to try these codes. Any combination I have tried and my RTI IR library manager either says invalid format or invalid zero length time detected. Is anyone able to give me the complete hex code string for inputs 1-5? Or maybe tell me what I am doing wrong. Here is an example of one I pieced together from the above mentioned file:

Input 1?
3D 92 02 8B 0D 49 05 08 00 84 01 75 00 84 03 87 83 C2 E6 24 03 20 10 0C 05 E4 03 05 60 05 90 05 0A FC B0 C6 A6 0D 02 EB 03 E6 0D 05 F6 01 46 60 04 60 05 F6 01 0A 7B 02 60 C6 F6 01 46 37 61 09 60 04 60 05 F6 01 0A 7B E3 AF 95 F4 64 45 7C 53

Trying to control the GD4 series sharp using these codes. Thanks for any help you experts here can provide!

I don't know what format you need for RTI library manager. I have no clue what you might have done to piece a string together from the above file, but I'm sure the RTI library manager can't use anything directly from a JP1 file.

Hopefully, you can use Pronto Hex. That can be generated with the MakeHex program discussed in many threads here. I tried to save you the trouble, by emailing the two files of MakeHex Output you would need, but the address in your profile is bad.

With two runs MakeHex you can create two files with all the functions for Sharp protocol device 1 and all the functions for Sharp protocol device 17.

Then you can select some specific functions from those files based on the info in post 5 of this thread.

The JP1 file has the info needed to select the rest of the functions from the MakeHex output. But it isn't in clear text. You would need to open the JP1 file in the KeyMapMaster or RemoteMaster program in order to see the OBC numbers on the functions sheet. Those OBC numbers are the "function" numbers in the MakeHex output.

RTI will accept hex commands.

I have the same television, LC-37GD4U. I have tried the following with no effect on the set, none of these work as discrete inputs for this model of sharp TV.

Functions 50,51,52,53,54,55,205,211 on Sharp Protocol Device 1,17 & 30.

Any suggestions to narrow down the search for hex codes for discrete inputs on this? I have found a hex code for input 5 that works and Antenna A and B. Discrete power commands is no problem, just inputs that I have no luck on.

Sorry. I have no knowledge about what differences there are between your model and the LC-52D92U described in post 5 of this thread.


If you tell us what those three commands are, that would be helpful for others reading this thread and might also give me a hint how to help narrow your search for the other input discrete codes.

These hex codes work:

Input 5 PC:

I haven't learned yet how to extrapolate the device code and function code out of the hex codes.

Also, does anyone know a way to create a file for RTI or Universal Remotes from a makehex output file? Its a little tedious to do it one by one, copying and pasting. I have tried the irpanels program which is great, if only I didn't sell my TSU2000 on ebay, DOH!

Device 30, function 129


Device 17, function 112


Device 17, function 113


Use this program
[Link: remotecentral.com]
with this DLL
[Link: john.fine.home.comcast.net]

I thought that knowing "Input 5" would help me figure out the others, but it didn't.

In the whole collection of CCF files I've downloaded, only one file even uses Sharp device 30:
[Link: remotecentral.com]

and that only uses functions 131, 139, and 140. And none of those are discrete input selects.

...started to post....

...realized I could not distinguish Sharp from Samsung.

...to late to be surfing RC forums.
