Select on Sanyo projector making me mad...

One alternative you have is to go "code hunting" within the upgrade and find if there are any EFCs that run the Select function.

The only warning is that some devices have "service mode" codes that are not published and if you send one of those to the device it may enter that mode and you'll have to figure out how to get it out.

Carl,
It's helpful to see the the learns from the arrow buttons, but we really need the learn from the OK button. If you can learn the OK signal, and show that the learned signal works, then we'll be able to decipher the learned signal.

Please post a IR file that has a learned OK signal which does control the OK function on the projector.

Here's the binary that I got from the learned signals. I think we'd need to see repeated learns of the buttons to properly determine what's happening with the second byte. We'd also need confirmation that the learned signals work.

1=+400 -1200
0=+400 -400

OK
+1600 -800 10110000 00000010 00000001 +400 -12000

Right
+1600 -800 10110000 11111101 00000001 +400 -7200
+1600 -800 10110000 11111101 00000001 +400 -8400

Down
+1600 -800 10110000 00000001 11111101 +400 -7200

Up
+1600 -800 10110000 00000001 10000000 +400 -12000
+1600 -800 10110000 11111101 10000000 +400 -7200
+1600 -800 10110000 00000001 10000000 +400 -12000

Left
+1600 -800 10110000 11111101 00000001 +400 -11200
+1600 -800 10110000 11111101 00000001 +400 -7200
+1600 -800 10110000 11111101 00000001 +400 -7200

This whole situation is odd. Carl, in your first post, you said that all the buttons except OK worked based on the upgrade you linked to.

The arrow buttons in that upgrade are NEC1 device 48.206, as expected. On the other hand, the learns you posted are not recognizable as NEC1. If the arrow buttons from the upgrade work, then I think that means that the learned signals are incorrect for some reason.

Does the Sanyo remote have fresh batteries?

BTW, the learned signals from the right and left arrow are the same, and down arrow just has the 2nd and 3rd bytes interchanged. Again, this makes me suspicious that something has gone awry in the learning process.

Please post a IR file that has a learned OK signal which does control the OK function on the projector.

Here is the learned ok button working:

The batteries are fines, I even went crazy and connected the Sanyo remote to an external 3 volt power supply.

Looking at the learn of the UP button, I suspect that the arrow buttons use a press/hold/release format. If that is the case, then the learns for the DOWN, LEFT and RIGHT buttons are missing the press and release portions.

Carl, do the learns of all 4 arrow buttons work? And if so, do they repeat properly when the buttons are held down? (I'm assuming that they repeat on the original remote).

I'd like to see fresh learns of the 4 arrow buttons. Please make sure that you put the JP1 remote into learn mode before you start pressing the OEM remote button, so we're sure to get the beginning part of the signal. Please learn each button 2 or 3 times (so learn to random buttons on the JP1 remote). Do at least one short press and at least one long press of each button.

Yes they do on the current IR file posted below.I even removed my upgrade to make sure all I have is the arrow keys working.

do they repeat properly when the buttons are held down?

Only Left and down repeats on this current IR file but they all repeat on the original Sanyo remote.

I've created a file with experimental learns. First, please confirm that the OK, left and down buttons still work, then test the numeric buttons (1 thru 6) to see what they do. Buttons 1 and 2 are possibly the RIGHT button, while 3-6 are possibly the UP button.

Thanx Rob, I will test this first thing in the morning on monday.
It's actually a projector from work.

It turns out that Sanyo has partial lists of IR codes for many of their projectors. Most of the signals are NEC1 or NEC2. However, for example, the ZM500 uses the Interlink Mouse Code Format. Perhaps that is the IR signal that Carl is seeing. The PLC-WXU30 additionally uses the Interlink OSD Mouse Code Format. (See the Resources page for the IR code list.)

I haven't found a description of the IR signals.
Carl, what model number do you have?

Carl · Post by **Carl** » Sat Apr 02, 2011 10:25 am

It's an old Sanyo PLC XU-37 (2004).

Here is a picture of the actual remote:

The XU37 manual says that the pointer and Select button buttons have two functions--either controlling menu picks, or controlling an on-screen mouse pointer. Page 39 implies to me that if the projector is in Menu mode, then conventional Sanyo projector signals will be sent. Otherwise, mouse signals will be sent.

I suppose that you want to be able to control the menu. To learn those signals, it will probably be necessary to put the remote into Menu mode (Tap the Meny button). Probably there is a timeout after which the remote will revert to Mouse mode.

I'm still curious. In your original post you said that using the Sanyo Master file, all functions except Select worked. Does that include the arrow buttons? If so, I really think you should check again whether OBC 15 will send the Select function.

it will probably be necessary to put the remote into Menu mode

I have just tried to decode the select button by pressing menu first and still getting garbage signal in IRscope.Good idea though.

In your original post you said that using the Sanyo Master file, all functions except Select worked. Does that include the arrow buttons?

Yes, the arrows worked with the upgrade.This is why I really don't understand this select button problem.I wonder how Rob did decode the arrows when he first did the upgrade.

The OK,left,down button work and here are the results for the numeric buttons:

1: Right arrow working
2: Right arrow working
3: Up arrow working
4: Up arrow working
5: Up arrow working
6: Up arrow working
