Hi,

For unknown reason my post was dissappeared so I reposted it.
I'm trying to program my JP-1 remote using Remote Master software based a remote IR Codes info below but wasn't successful since I'm new to this software. Please guide me.

Thank you.

Technical details
The encoding of the keys is similar to other Sharp remotes, using a 1ms pulse period to signal a 0 and 2ms pulse period for a 1. However, there are only 12 total bits sent (and therefore 13 pulses). Codes are sent every 40ms, inverting the last 9 bits every transmission (e.g. a toggle mask of 00011111111).

Function Code

We get a lot of AI spam here where someone posts on the same day they joined and they make a post with very little info, which is what your original post was like, so that's why it got deleted. Sorry.

Now, before we try to reinvent something that might already exist, could you please state what device you are trying to control and where you got the information that you posted?

The device I'm trying to control is Sharp Monitor CZ-600DB. It's monitor for X68000 computer. My remote is ARRX15G from Acoustic Research.

The remote IR codes info I got is from this site below.

Why don't you try capturing the commands using IRScrutinizer? It will eliminate the guessing game on exactly which protocol you are dealing with.

You will need to buy an IRCapture Device or IRWidget if you don't already have one.

I believe the ARRX15G is a learning remote, so why not capture the signals from your TV remote using learning?

Yes, the problem is that I don't have the remote. I would have to borrow from someone who has one

Hi Skusuma,

the problem is that literally interpreted, the desciption
Skusuma wrote:

is unintelligible. With that "encoding", how can we tell two 0 from one 1?

There is a Sharp monitor at IRDB. It uses signals with the "Sharp" protocol, using D=1. There are also some Sharp TVs as device upgrades here. The also appear to use Sharp D=1.

Please try it. Dowload with IrScrutinizer/Remotelocator, export as Girr, open the Girr file in RMDU, and off you go. Or just use this.

I agree that, overall, the description is vague enough that I don't want to spend all the time that it would take to write an executor and have it not be correct.

The bit that you quoted isn't the problem for me. They said the signal was similar to Sharp, and Sharp is defined as "<1,-3|1,-7>", so I assumed this is the same.

The complete Sharp IRP is "{38k,264}<1,-3|1,-7>(D:5,F:8,1:2,1,-165,D:5,~F:8,2:2,1,-165)+", which is a 15 bit signal which has a 5-bit device, 8-bit OBC, 2-bit switch, then that 15-bit signal is repeated, with the OBC complemented, and the switch changed from 1 to 2. This pair of signals is what gets repeated when the button is held.

The description here says: "The encoding of the keys is similar to other Sharp remotes, using a 1ms pulse period to signal a 0 and 2ms pulse period for a 1. However, there are only 12 total bits sent (and therefore 13 pulses). Codes are sent every 40ms, inverting the last 9 bits every transmission (e.g. a toggle mask of 00011111111)."

When they say 12-bits, but then describe it as 13 pulses, I'm not sure what the 13th pulse is, perhaps it refers to the lead-out pair? They do describe that 9-bits of the signal get complemented on a repeat.

So, is this signal really the same as Sharp except for losing 1 bit? In a Sharp signal, the first 5 bits are the device code, and the next 8 bits are the OBC, but in the table of bits that they posted, it's the middle 5 bits that appear to be the OBC, with 3 or 4 bits of zeroes on either side.

Also, the data in the table appears to be in MSB format, whereas Sharp is LSB, so are the bits in the table reversed?

So, bottom line, there are way too many unknowns for me to risk trying to write an executor based on what was posted.

Skusuma, do you know how to paste Pronto hex as learned signals in RMIR for your remote? If so, I have posted some possible codes for POWER below.

If you don't know, download an RMIR image from your remote and I'll add them to it.

The description is confusing, but I think a simple IRP is
{38k,264}<1,-3|1,-7>(A:3,B:9,1,-165,A:3,~B:9,1,-165)+
where I have deliberately avoided attributing A and B to concepts like device or OBC. BTW, this particular description may be closer to Denon because for Denon, the 2 bits following F and ~F are 00 and 11 rather than 01 and 10 as seen with the otherwise identical Sharp protocol. We can't tell if this (presumably older) code has such manufacturer info encoded or not.

I think it is intended to be LSB, because numerals 1-12 are encoded starting at the 4th bit as 5 bits spanning 10H to 1BH ( i.e. 16+0 to 16+11) if read as LSB.

The "13 pulses" just refers to the necessary trailing mark that we always have with protocols employing mark-space1 and mark space2 to denote 0 and 1. If there is no trailing mark, the remote can't tell how long the last space is. Of course I tend to think of this trailing mark as part of the lead out, but others may conceive it differently.

Rob,

The 1st attempt worked. You're amazing. How can I convert the 12 bits to this pronto? Thank you so much for helping me.

Rob,
I saw the patterns of the pronto code:
0000 006D 0000 001A
IR Binaries (convert 0 to 000B 001E and convert 1 to 000B 0046)
0633
IR Binaries Mask (invert last 9 bits of IR Binaries)
0726

I was able to get CH Display button to work as well.
CH Display button pronto code:
0000 006D 0000 001A 000B 001E 000B 001E 000B 001E 000B 001E 000B 001E 000B 0046 000B 001E 000B 001E 000B 001E 000B 001E 000B 001E 000B 001E 000B 0633 000B 001E 000B 001E 000B 001E 000B 0046 000B 0046 000B 001E 000B 0046 000B 0046 000B 0046 000B 0046 000B 0046 000B 0046 000B 0726

I will create a full set of Pronto codes for you, then I'll think about writing an executor for it.

I've been reading the code in the Sharp executor and I think it's already programmed to handle this signal. The first logical statement tests the LSB of the fixed byte for 1, which it never is with Sharp or Denon, and if it's set, it looks like it reduces the signal length from 15 to 12.

I have created an upgrade that I think will replicate this, but I haven't tested it:

If this works, we'll need a new protocols.ini entry for Sharp Monitor.
