1. Device: no brand AV selector and Pioneer DVR-520H
2. Type of device: AV and DVR
3. JP1 Remote model: URC-9960 and Philips Pronto
4. JP1 user? yes, used the kameleon and cable to learn some codes
5. Still have original remote? yes
6. Checked the file section? yes
7. Checked the Pronto file section (at R/C)? yes
8. Partially working setup code? yes, all codes work OK
9. Learning remote question? no

Since I wasn't able to find these anywhere, I would like to know if it is possible to somehow guess or calculate the discrete codes for the following functions (provided that the devices support such discretes):
A/V selector -> discrete on, discrete off
DVR -> the input function (it is a function that toggles the external input between L1, L2, L3, DVD and Tuner currently controlled by one toggle button)

Of the A/V selector I know that it uses protocol NEC1, device 134, subdevice 107. The power button uses OBC 30, HexCmd 87 and EFC 246.

The DVR uses the Pioneer protocol (2 commands per function), device 171 and 175, no subdevice. Unfortunately I didn't learn the "input switch" command using the kameleon but have most of the other commands learned.

I no longer have the kameleon as I use the Philips Pronto now, so here is what I got from the Pronto:

A/V Switch
learned using Pronto
900A 006D 0000 0001 866B 1EE1 # power
900A 006D 0000 0001 866B 02FD # 1
900A 006D 0000 0001 866B 06F9 # 2
900A 006D 0000 0001 866B 08F7 # 3

Just FYI, NEC1 134.107 matches CBL/0770, which can be found in a few old OFA remotes.

Anyway, if the POWER button uses OBC 30, and the 1,2 and 3 buttons use OBCs 2,6 and 8, I would suggest that you test the rest of the OBCs in the range 0 thru 31 to see if you can find the discretes that you're looking for.

As for the Pioneer, the commands you posted uses the standard 2-part Pioneer signal with the following codes...

Code:
dev1 obc1 dev2 obc2
171  042  175  174 - input select DVD
171  044  175  187 - off
171  044  175  186 - on


Just FYI, if you run your Pronto files against DecodeCCF (and DecodeIR) it will give you all the code info.

Thank you very much for your reply.

I have tried the codes as suggested. Either I did something wrong or the device does not support discrete on/off codes. I kept changing the second last byte leaving the rest intact - was that correct? Since there is not much risk in invoking some unwanted codes in the A/V selector, should I perhaps try all codes in the range 0-255?
I am just trying to get a better understanding of how these things work so I would like to know why 0-31 range is sufficient?

About the Pioneer. I am amazed that all that long command translates into something so simple. Is there some kind of information available that would explain how this is done? I did not find anything like this anywhere so I am guessing that this comes with experience?

What I really would like to do with this "input select" command is this. Currently I have to press is several times as each press will advace the selection in this loop: L1 -> L2 -> L3 -> DVD -> TV Tuner and back to L1 etc.
But when I run a macro to say watch a DVD I have to go directly to the DVD selection. But there is no way to tell how many times this button should be pressed. The same goes for L1, L2 etc.
What I would like to be able to do is to turn this command into 5 discrete commands if that is somehow possible.
I know that the DVR may not support this. But if it does I wonder if I could find these discretes somehow? I guess I could try changing the last bit of the command until I stumble on a working command just like with the A/V selector. But I am a bit worried that I may accidentaly stuff something up on the DVR.

What is the most common way of finding discretes for a device like this?

I have what may be the same switch. Mine is only a fiber-optic switch with 4 inputs and 2 (parallel) outputs. All the commands are the same as yours, but the 4th input is OBC 4. I believe I tried all codes and found no descretes, but it was some time ago, so I am not sure. If you do find descretes, please post them here.

This is the one I have (hope the link works, if not you can do a search for CAT. NO. AC1674 on that site):

Does an A/V selector really need to be turned off anyway?
When I built mine, I built it with no consideration for "turning it off".

When you said you are a JP1 user, even though I know you no longer have the Kameleon, I assumed that meant that you still had at least one JP1 remote that you could program using the codes that I posted.

However, I see from your reply that you need to know how to edit the Pronto hex. You should notice that there are 2 bytes that change when the command changes, the first byte is the OBC in hex format and the second byte is the complement, so you would need to edit BOTH bytes.

Sure, I would agree that there's no risk, so knock yourself out. I just picked the first 32 OBCs because I consider that to be where any additional commands (if they exist, which it sounds like they don't) would be present. It's quite common for NEC signals to skip OBCs 32-63, which is why I stopped the range at 31.

There's plenty of documentation that explains the long hex string you posted as that's an example of a raw learn. The shorter strings that start with a 9000 number are using an internal database (supplied by UEI, funnily enough) that describes the format of the signal. I don't remember enough about that format to describe how to format a string from scratch, but given all the additional data that was present in your post, I knew that these were Pioneer signals, so all I had to do was translate the hex codes into decimal to give you your answers.

This is the classic reason why people need discretes. I'm not familiar with the Pioneer DVR, the only DVRs that I'm aware of under that brand are their Tivo models, so I don't know if it supports discretes or not.

If searching the web fails, the only other option is to randomly try all the un-accounted for OBCs, as you are doing.

Just in case some other user finds this thread in the future, I have created a JP1 upgrade for the A/V selector here:

That is true, it does not have to be turned off. I just thought that given its simplicity I would be able to learn how to discover "hidden" codes.
Unfortunately following Robman's advice I am almost certain that it does not support discrete on/off commands.

As for the Pioneer DVR.
Given that the "input select" command is 900E 0068 0000 0002 AB54 2AD5 AF50 AE51 I tried a simmilar procedure to search for disrete codes (incrementing the last part from A0 to AF) but did not find any.
So it seems that my only option is to create a power off macros for each mode that will ensure that before turning the DVR off the input will be set to L1. If all my off macros do the same, then the on macros can advance from L1 as required.

Thank you for everyone's help.

This is the list of all codes from Pioneer's website in case someone is looking for a code for Pioneer DVR-520H codes.

I just converted those codes into a JP1 upgrade file...

If a discrete input select is not forthcoming, how about a virtual discrete? In other words, is there a command (e.g. discrete ON or discrete OFF then ON) that always jumps to one input or does it simply leave it hanging at whatever input which was previously set?

Yes, when powered on the input always stays set to the last used selection.
It is kind of strange that there are no discrete codes for this functionality.

I've found the same problem with my Pioneer Home Theatre Amp. I need to change the signal select from digital to analog when I'm changing from my DVD player to one of my VCRs. I have four possible settings. My DVD Select macro sends the signal select command twice to change from AUTO (digital for the DVD) to ANALOG (for the VCR). If the sound is coming from the wrong source or there is no sound, I just press the macro button a second time. My VCR2 Select macro does the same thing.
I'm happy just to have the function at all, considering the original remote doesn't even have this function. Thanks Rob, for the Pioneer master code list.

Actually I discovered a neat trick. Selecting any channel (by pressing a digit button) will set the input to TV.

Given that my input sequence is L1->L2->L3->DV->TV pressing the button positions the input at the end of this sequence.
And from there it is easy to work out how many times I need to send the command to set the input to say L3 (3x)

That is, in fact, a pretty standard workaround for discrete inputs on TVs/Tuners. It also often works using either the channel up or down function. I point this out since it is often the case that when using a numeric channel selection, there is a time delay before some receivers "act" on the command, awaiting a possible second digit to be sent. The CH+ or CH- formulation has the benefit of immediate response from most TV's/Tuners. (The disadvantage, of course, would be that after a week of watching various video sources, your TV may be tuned to a channel 20 or 30 or so numbers higher than you ever intended it to be.)
