I have on/off discretes working, but still need discrete inputs for Input 1-4 (I also have discrete Input 5 - PC Direct, which works great).

Need them in Pronto TSU3000 Hex form or some form which I can convert to Pronto...

Any help or advice on where to look, what to try would be appreciated.

Thanks!

Well, by playing around with ProntoUtil, discovering the CCFCompiler, and learning a little bit about IR codes with MakeHex and irTool, I figured out how to generate a bunch o' codes and test each one with the Pronto...

Generated 0..255 codes for device 30, 17, and 1, in the Sharp/Denon format. Found some interesting undocumented codes (service menus, etc, including one which placed a boxed [K] on the display in the middle left and required a system reset to remove), but no discrete inputs!

Next step is to learn all the buttons off the OEM remote, use irTool to decode them to see if the unit uses a device code other than 1, 17, or 30, and if so, use ProntoUtil to generate code pages for that/those devices(s).

Failing that, I'll be buying a Xantech IRS232A and the associated gear (power supply, IR picker/upper, remote control) to the tune of about $500 and I'll drive the inputs via RS-232 port on the Sharp. I may do this anyway, since it allows greater use of all the inputs anyway (because it allows discrete usage of component vs. composite video inputs, for example)... How to sneak that component into the house w/o the wife noticing yet-another-peice of gear?!

Enough rambling and on with the job...

If you have input-5 (assuming that is the highest) then a macro for input-5|video Toggle is tuner, input-5|video Toggle |video Toggle is Video 1, etc. Also on most TV's ch+/- will bring it to the tuner if so you can save one macro step. The Pronto apparently can execute macros very fast (you might even need to put in slight delays) and you may not notice the cycling through input commands.

I believe there are also some IR to RS-232 boxes in the $100 - $200 range, or if you have a home server, for some programming you can use girder to trigger the RS232 commands.

jarmstrong,

Thanks for the advice. I've tried the AntA+2*Input = Input1 and AntA+3*Input=Input2. It will work, but by the time you get all the delays in there, it is very slow and not very wife-friendly (who may not continue to point the remote at the system). On top of that you see the snowy picture coming from the AntA input for a bit, which is just not very pleasing.

I do eventually plan to setup a HTPC. Right now I have a Dell XPS system which has enough performance but is relatively loud w/ all the fans and such. I will eventually look into building a quiet PC from scratch (I've already replaced the sound card, ethernet card, and added an additional video card to this year old system, so I have some parts laying around!).

So... I'd rather not have the PC running just to switch inputs on the TV. It is looking more and more like I'll be purchasing a Xantech IRS232A... unless anyone has recomendations for another unit.

Update on progress: I learned all the buttons from the OEM remote -- all are device 1, 17, or 30. So it appears that my manual search for IR discretes is over -- they may not exist and I'm not willing to search manually through the other 29 possible devices (each with 256 codes). I have gotten a couple of spreadsheets from the Yahoo Crestron group that I will look into as soon as my ordered copy of Excel arrives (my old Excel 95 would not read them -- forcing me to upgrade).

I also intend on contacting Sharp about the issue and see if I can talk to anybody that knows what I'm asking about (I expect most of the customer service techs will not have a clue about discrete IR codes...)

Side Note: Amazingly stupid of Sharp to include ANTA/ANTB discretes on the remote, as if anyone in their right mind is going to watch TV/CBL from the RF ant inputs on their $4500 TV...

You might check both pages of this thread:

[Link: remotecentral.com]

if you haven't seen it already. I also got two official looking spreadsheets from one or two of the installers that I believe were from Sharp and I translated it and there were two different command sets. It will also tell you how to "translate" what you get.

Here they are but in that thread I think someone found some additional commands. Therse are all translated to what MakeHex uses and in decimal. It looks like the first set should be for your model/series:

BTW, I went back and reread that thread and "fischdaddy" reported 13:52 was video 3 (he got it from a projector) so I would try 13:49 throught 59 and you might get lucky.

Thanks... I started with the thread you mentioned (there is another one too that has codes marked SHARP-MASTER) and tried the codes there. That's where I got the PC-DIRECT, ON, OFF, discretes, which work great. But I'm toast w/o discretes for the inputs.

I've tried the projector video 3 posted and it doesn't work on the LC-37G4U. But I guess it is worth it try all the device 13 codes, and see if any work. It is just 256 button pushes after all...

Confirmed: This TV, LC-37G4U, does not respond to any device 13 codes.

Do all the other commands in Set 1 match what works for you?

Not all, but many...

1,1-47 match function on my set.
1,50-52 no function (should be inp1-3)
1,64 match
1,74 match

1,81 is twin picture (this set has twin picture side by side, not p-in-p)

1,83 is freeze (function in twin picture)
1,87-88 match
1,110 dolby virtual toggle
1,160 view mode toggle
1,169 no function here
1,177-179 match (a,b,c,d) fav keys
1,211 no function
1,244-248 match
1,254 no function

17,9;58-60 not sure about these (may not have been in right mode when I was testing all dev17 codes)

17,74-75 match (discrete power control)
30,129 match (input5 discrete, DVI on my set)
30,139 didn't notice a function here (what is LUMP?)

Here's some additional codes I noticed doing something during my testing (I'm only listing codes that don't have a button on the OEM remote):

1,49 - a kind of service menu/display (diff than 1,64)
30,199 - "public" menu ('nother service menu of sorts)

30,212 - some kind of test mode, causes display to flash between ANT-A ch4 and garbage. must power down to standby to get out of this.

1,119 - displays AV MODE STANDARD at bottom of screen and places s [K] (in a box) on left side of screen. emitting another 1,119 will remove the [K], but it will re-appear when coming back out of standby. must do complete system reset to get out of this mode. also -- going into CARD mode will display a diagnostic menu when the [K] is present on the screen.

Truly strange. If it will help I can email you the spreadsheet that is HV4U.xls so you can forward it to their customer support with what works and what doesn't. It may well be the easiest way to communicate they can correct it and tell you the right commands.

I am beginning to wonder if it is a firmware issue. For example, Toshiba apparently forgot to program in the discrete power commands on some recent HD RPTV's -- and sent out new chips to fix it.

It is possible but not likely, that somehow the framing is off and it is not interpreting the command correctly, but it is too much of a coincidence that all the input commands are missing.

Maybe John Fine who ususally monitors this board has some better idea.

Sure. Send it to [email protected]

If you have any good contacts at Sharp, I'd take those too... just dreading the 'wading through the idiots' part of calling tech support.

Thanks,

You might want to post this question at the professional installers forum. Just explain your model number, the spreadsheet name (presumably the correct series) and ask if anyone has any ideas and/or contacts. I think you have as thoroughly researched the problem as anyone I have ever dealt with.

You might want to post the Pronto hex from a few learned commands from the OEM remote and post the Pronto hex, just in case there is some minor protocol variation. Perhaps you have already looked at that.

BTW, I sent you the spreadsheet. Please keep me in the loop as you progress. This is a real brain teaser.

What 13 sets of codes? In the built in library? Did you go to MyNevo.com.

There is a brief faq here explaining what to do:

[Link: pocketpccentral.net]

Nevo is a product of UEI that makes the One-For-All series of remotes. Their library is also in the higher end Pronto's. So I supect that they will be very helpful. After all, UEI upgrades $30 remotes for devices not in their built in libraries.

I couldn't find your exact model. The closest I could come was this file for XGE3000U XGNV2U (space added since Premise always runs their device numbers together):

[Link: ir.premisesystems.com]

I spot checked the commands and they look like most other Sharp projectors. So, I'm back to wondering why didn't any of 13 Sharp projectors work?
