JP1 Remotes

Is this enough information to derive Pronto hex codes from, or will I need more?

This from the Kodak Manual

Not sure where to start with this.

Do you not have the original remote for this? If you do, I'd much rather see some captures from your IR widget.

Here are the OBCs at any rate...

16 - slide forward
08 - slide backward
04 - focus forward
02 - focus backward
01 - standby
20 - 0
21 - 1
22 - 2
23 - 3
24 - 4
25 - 5
26 - 6
27 - 7
28 - 8
29 - 9

At most, I believe that tells us the Original Button Code (OBC) except in binary instead of decimal. Doesn't look like there's any way of knowing from the manual exactly how these are formatted in the IR signal though. Tried to find match from the usual suspects but was given Kodak Etkagraphic as a consolation result. Recorded its IR signals with the JP1 tools to create the respective file. Unfortunately, they came up as <unknown>, so I'm not exactly sure if they will help you. Perhaps a senior expert can assist further.

Do you have the actual Kodak device? And if so, do you still have your URC-8910 remote? If so, I can format some learned signals for you to test and if they work, we can either create a protocol upgrade or pronto hex, depending on which you really need.

Unfortunately no original IR remote.
(I'll keep enquiring about this)
The remote with it, is a cable remote.

The IR receiver and remote was an optional accessory I think. (I have the receiver which just plugs into the 'cable remote' port instead.)

I'll have a try with your Ektagraphic results too.
Still have an 8910, also an 8820, and a 7781 which I use most.

The Ektagraphic file that eferz posted is just an ICT file (which you would view using IR Scope) it's not an upgrade file because it uses an unknown protocol.

If you had an OEM remote in your hands, would it work with the receiver that you have? If you think it would work, I could format an IR file for your 8910 that contains learned signals for you to test. Because there's no point in developing a new protocol and upgrade if you're not able to test it.

I'm having trouble reconciling the ICT with what I read about the timing of transmission and the little drawings after that


Timing of Tramission
a. Interrupt cycle: about 100 ms
b. Duration interrupt pulse: min. 0.75 µs, max. 1 µs later
c. Valid data: min. starting with interrupt edge, max. 8 µs later
d. Data transmission time: min. 600 µs, max. until the next interrupt

Me too, but as there wasn't enough usable info in the PDF, I figured we'd see if Earl's learns were good and follow that route.

Page 3-20 of the repair manual makes clear (to me, at least) that the signals described are not IR signals.

The projector has an IR receivber interface with 5 parallel data lines and an interrupt line that plugs into the projector. The timing and data values refer to the state of those wired data lines. The IR signals are likely to be different.

After doing a little more research on a very SLOW wi-fi connection, it looks like most of the Kodak "ekta" type projectors require a dongle like device to receive the IR signal. I wonder if this "Ektapro" module has a similar receiver.

Here are all the resources I'm using, sorry if I left something out.

As the IR receiver is with there, I figured I'd try and use it.
The P-Com (RS232) connector is available too for control, but on my first try with my laptop I couldn't get a response from the unit, so thought I'd try by IR instead.
I've just read that the "Standard 8 Pin Connector" (cable remote and IR receiver plug in here) also incorporates contact closure for Tray Forward and Back, which I'll try too, as this is possible all the functionality required.

I was going to take the ICT file and generate pronto hex from it, and fire it from my laptop and see what happened.

As I mentioned earlier, I can easily make an IR file for your URC-8910 that includes learned signals replicated from eferz' ICT file, so you could use your 8910 to test.
