Proton (5C) protocol

floyd1977 · Post by **floyd1977** » Thu Jun 26, 2008 7:03 pm

I just bought a Mitsubishi HD projector (HC5000). I didn't see any Mitsubishi upgrades in the Projector section under Device Upgrades. I learned all the commands from the remote and they all decoded as Proton signals, device 240. The commands work fine on my URC-9910 if I hold down the button for a fair amount of time (i.e. a quick tap will not work), but the commands do not work in macros. All I really need to do in a macro are the discrete inputs and discrete power off commands.

Is there a way to extend the signal duration for this protocol? Or is there a different solution? I've tried inserting delays (pause protocol, up to the maximum value of 0xff), and I've tried changing the order of steps in my macros, with no success.

Any help is definitely appreciated.

Thanks.

Are you using the learned signals directly in your macros, or have you built an upgrade using the decoded data and are using the upgrade as the source for your macros? If your using the learned signals directly, I'd suggest trying to build an upgrade,

There is a UEIC Setup code for this (TV/0868), but it appears to only be built-in in the newer remotes only (RS 15-2144 and 100, OFA URC-6690, 8820, Atlas URC-1054 and 1055).

I doubt that it's in your 9910, but it's worth a try.

Thanks, Capn.

Yes, I should've mentioned that I created an upgrade with the learned functions. I'm using the extended URC-9910. According to the ofausa.com website, TV/0868 is not available in the 9910, but I can check when I get home.

If it is not available, I guess I could call support to download an upgrade.

If your upgrade uses the 005C Protocol, then any upgrade UEIC provides will also use the same protocol, so you're likely to have the same problem with duration of the signals embedded in a macro.

Have you tried the relatively easy workaround of sending the same signal several times in succession in your macro? Some devices will percieve this a single longer duration signal rather than several short signals.

If that doesn't work, then you need to extend the duration of the signal somehow. One option is having an expert provide you with a custom-tweaked version of 005C with extended duration.

Another alternative if you can't wait for an (find a willing) expert and/or want to do it yourself, you can do this using the Device Combiner protocol instead of the Proton Protocol (although you will require some data from that upgrade you built).

One of DC's less-obvious side-benefits is that for 1-byte signals (as yours is) it allows you to adjust the duration of the signal. Check out the Protocol Notes for Device Combiner in KM and/or RM and you will see that you can do this pretty easily (but you need enough memory available for the DC Protocol Upgrade, which is usually about 140 bytes!)

Thanks again. I'll try out your suggestions tonight or tomorrow.

I actually have enough room for the Device Combiner protocol, so I'll try the double command trick first, and if that doesn't work, I'll just use Device Combiner and play around with the duration.

Unfortunately, my PC with the parallel port is on the 2nd floor of my house, and my projector is in the basement, so all this trial and error stuff is giving me a workout.

Quick terminology lesson, you are using EITHER learned signals OR an upgrade, you can't be doing both. In your case, you are using an upgrade that you built based on the data found in the learned signals.

As for all the exercise that you're getting, maybe it's time to get a laptop!

Rob,

I agree, I could've worded that better. By saying, "created an upgrade with the learned functions," I meant "I used the learned functions to create an upgrade," not "I created an upgrade which contained the learned functions."

I actually have a laptop for work, but unfortunately, it doesn't have a parallel port. If I ever change jobs and buy a personal laptop, I'll be sure it has a parallel port, specifically for JP1 purposes!

You could also get a USB cable for the laptop. Tommy Tyler has created two new, very cool looking, USB cables. One is for JP1 and the other is for JP1.2/3

If you do decide to get a laptop with a parallel port (and/or a serial port for JP1.2/3), you'll probably want to get a Dell Latitude (like the D610 for example).

Rob, thanks for the USB cable info.

Capn, setting the duration in the Device Combiner protocol works perfectly! In fact, before trudging back down into the basement, I pushed the projector input selection buttons on my remote and observed the LED staying on for much longer while sending the signal, so I just knew it would work.

Thanks for all of your help. Once again, you guys have helped me to get my remote to do exactly what I want.
