Dear all

I have an OFA URC-8550 with JP1-interface and latest version of IR-software. I'd like to know if its posible to programm my RC to controll a "NEC MT1060" LCD video projector. Or is it generally imposible becouse its not compatible?

thanks in advance.

Check this thread for beginners first.

To get the most out of the remote, you'll need an interface. Not the connector in the remote, but rather a cable to connect your computer to the remote. This is how IR communicates with the remote. I'm not familiar with your remote. Check this thread as well to determine the type of interface you'll need.

Post back after you've gone through this stuff.

The short answer is if your remote is already jp1/jp1x compatible, you should be able to control the device.

Other people have already posted upgrades for these Nec projectors. Chances are one of these upgrades might work your projector.

Firstly thank you very much for answers.

I have already the cable, and had already connaction between PC and remote, so it works. At the time I just go through the document "JP1_For_Beginners_Rev1.0.doc" and try to learn how to work with the IR.EXE...

@vickyq2003: can you just give me the link for this NEC MT820. can't find it...

If you click on the file section at the top of the page you can find all of the projector upgrades

File Section

You'll see a list of Device Upgrades
Device Upgrades
Upgrade files for use with either KM or RM.
Sub Category: AC & fans, Audio, Cable, Cameras, CD, Digital STBs, DVD, DVD / VCR combo units, Home Automation, HT Systems, Keyboards, Laser Disc, Misc, MP3 Players, Projectors, PVR, Satellite, Satellite Radio, Tape, TV, TV Combos, VCR, Video Selectors, UEI Official, WAV Files,

Scroll down until you find the item you want. If it ahs a KM icon

, it will work with the Keymaster program or the RemoteMaster Program. The RM icons

will require Remotemaster.

@vickyg2003:

Thank you very much for help! I loaded the data of the NEC MT820 and now can even controll my MT1060 with it. So I learned how to upgrade the RC.

But I would like to know how can I get these OBC/EFC codes, and where can I get the protocol of the device I want to control? Is it posible to get them from HEX-codes I learned with WinLIRC?

Assuming it is in prontohex format then yes it is possible to decode that to get the information we typically use. I believe decodeIR handles that but not too familiar with the details.

Question to all who knows WinLIRC and IR !!!

If I have an unknown device nobody deals with before and want to upgrade my URC to controll it, so I need protocoll-ID and the EFCs (or OBCs) for each button-code. Right?
Is it posible to learn the original remote with winLIRC and get the necessary information from its config-file to build an upgrade-sheet in KM?
Or are there other possibilitys to get the protocol-ID etc. ?

In most cases experts here can look at the learned signals in an LIRC conf file at tell you the protocol, device and subdevice and also tell you how to translate each function's lirc hex value into either JP1 hex or OBC

We don't have any software that does that translation.

If you post an LIRC file (or better, the URL for an LIRC file) I'll take a look.

Could you also tell me how to find the protocoll, and EFC/OBC etc. out of these codes? That would be great.

Thank you very much for the answer, johnsfine! You helped me very well.

So as I see its better to work with RemoteMaster if you have WinLIRC...Using Keymap-master and Devices.xls etc. its more difficult to get the required data for building an upgrade-sheet.

johnsfine · Posted: Mon Feb 18, 2008 9:36 pm Post subject:

If you don't have RemoteMaster, you can use the EFC calculator from the tools menu of IR.exe

Type a Hex value into the Hex field of the EFC calculator and you can read the OBC number from one of the other fields. For this case (NEC1 with LIRC reversed identically to JP1) that other field is LSBcomp.

But you would go back and forth between KM and IR.exe and end up typing twice as much as if you used RM.

Oh boy! I didn't even notice that there is a calculator in IR! Thanks again!

But how does the calculator convert the codes? Do you know the relation between HEX and EFC/OBC?

And about the protocoll: how did you know that its NEC1? only experience? or are there some sources/files where you can verify it?
