JP1 Remotes

I have an Audiovox TV KM Upgrade definition with Setup code 0003, and I am trying to do a keymove using IR (power and volume) to the AUD and VCR modes. Not working! Any ideas why and a solution?

By the way, why does the volume pass-thru work to everything but AUD and VCR?

You didn't tell us what remote you are using.

Volume pass-thru breaks when you change the device type for a device key. For example, if you uses a CD setup code on the VCR key, volume pass-thru won't work for the VCR key.

It might help if you post a copy of your save IR file.

Thanks... I am programming a 6131, and the IR file is:

http://groups.yahoo.com/group/jp1/files/Diagnosis%20Area/Kitchen.txt

The device type is TV for the TV upgrade file, yet the volume pass-through nor the IR-programmed keymove work from device 0003 volume or power to the AUD/VCR modes. Doing a manual "994" on the remote works fine so I can limp along, but I'll have to go through a lot of keystrokes after each time I modify the programming.

The key here is that you're using a 6131. If you do a search you'll find that we've mentioned many times that the 6131 uses a different format for keymoves, so doing them in IR is difficult and should be avoided.

However, one you've entered a keymove using the remote, you can clone it using IR if needed.

The authors of IR are looking into modifying IR to handle the new keymove format.

I type too slow , I started this reply before Rob responded and I have to edit it before I finished it (I'm not going to retype the whole thing) -- but what Rob just said -- and note my third paragraph on odd things because this applies to what happens if you clone a keymove and then try to change the bound device or key.

I've got 5 of the 6131's and love it -- but you can't do a normal keymove with IR on this remote. If you search the forum enough you'll find what you need to do. Basically , you need to select hex for the command type but enter 00 XX , where XX is the desired EFC converted to hexadecimal with a scientific calculator. Just ignore the numbers which show up in IR's display and it will work.

A few odd things will also occur. The keymoves generated within KeyMaster (KM) or RemoteMaster (RM) work without modification when pasted in as an uograde device (unless you try to modify them with IR). If your keymove is working and you change the bound device or bound key , you will have to enter the EFC->HEX manually again. If you used RM (or KM ?) to add "external functions" It will NOT calculate those keymoves correctly and you will have to re-enter the EFC->HEX manually. (I discovered this bug thinking I could get around the keymove oddity by using RM to add the keymoves from other device codes in a customized upgrade device)

If you look at the memory available on IR's bottom row , you will see a lot of upgrade memory and very little keymove/macro memory (on a device with 2k eeprom) and very little of each on a current UEI (1k eeprom) official upgrade. This makes the 2k version a prime candidate for an extender ("normal" keymove available) but with the 1k version you will have to be very innovative to create complicated upgrades.

Also, just FYI, the 6131 uses 2 keymove formats. The first, as described by Zaph, uses 2 bytes where the first byte is 00 and the second byte is the hex representation of the EFC. This is the format that it will use if you program an advanced code manually on the remote. The second format is used when you copy a button from one location to another on the remote itself. This format uses just 1 byte which contains the keycode of the button that you copied from.

So, if you're running out of keymove memory and have upgrade memory to spare, you should create a dummy upgrade which contains all the EFCs that you need to program via keymoves, then copy the buttons from this upgrade to make keymoves. This way each keymove will use a total of 5 bytes of memory, rather than 6.

Actually I did do the 6131 shuffle, namely take the code, convert to hex, and do the 00 XX construction in IR, so that's not it. I've done that dozens of time for other remotes and it works fine. Strangely the volume pass-thrus to all but the AUD and VCR modes work just fine, and the manual keymoves on the remote itself using 994 work just fine, and I assume the 994 accomplishes the exact same thing as the IR keymove construction.

Could it have something to do with the use of 0003 code which is an existing code instead of the "1003" renaming? I'm reaching here I assume.

[I confess to ignorance at this point as to what IR is doing with the "Hex Cmd" and "EFC or Key Name" columns which, in the case of Vol+ OBC=003 causes $46 $20 and 154x to appear there.]

I am lookig at my KM Functions, and the Byte2 column is grayed-out so I would say no.

I found the simplest of errors. I had used the OBC and not the EFC copied from the KM definition and entered into IR manually with the two byte "00 xx" hex conversion.

I might just start using KM instead of IR to do keymoves, but it does introduce the extra copying step which is

I have searched and searched for a succinct definition of the relationships between EFC, OBC, Hex, key numbers and al that jargon. Anyone have a good link for dummies?
