Airboard IR Receiver

"Macho macho man" :smile:

My god we laughed so loud with Ron on that one :wink:

Anyway, please read my answer in this thread http://www.girder.nl/phpBB/viewtopic.php?topic=452&forum=2#3

Basically, a lot of ir receivers are blinking to any code floating in the air. that doesn't mean they can handle those. They're not made for it.

Things like IRman can.

A universal remote can because it is designed to accept a wide range of ir codes.

What port on the PC does the airboard receiver plug into? Is it one of the PS/2 (keyboard/mouse) ports or a serial port? If it is a PS/2 port, the 8259 micro (or equivilent) inside the PC could be filtering the data. Have you tried probing the connector pins while using the receiver to see if data is being transmitted to the PC when you press a remote button vs a keyboard key? This could also show you where the filtering is being done.

I suppose you are going to tell me you don't have an o-scope at home to test this. :wink:

I read in the AVSForum that "Girder is kind of a "real men don't need manuals" type environment". Now, I guess it is also a "real men have o-scopes at home" type environment. :smile: :smile:

Exactly. Since the receivers "see" the signal and blink in response, the IR data si being received and filtered somewhere. We are trying to see where the data gets filtered (in the IR receiver or the PC). If the receiver is filtering the data it doesn't understand, so be it. If the PC is filtering the data, we may be able to change this behavior.

I haven't seen the results of this experiment on the net so I'm very interseted in the outcome. :smile:

Is there a way that I can use the Airboard IR receiver for my Airboard keyboard with my remote.

When I press a button on my remote, the light flashs on the receiver by it does not get passed through so girder can grab it. I don't know if the filtering is being done in the IR receiver itself or not, I think the IR receiver is the filter.

I also have a wireless mouse that works the same way.

Anybody else wonder about this???

thanks

Yup, I have a Scope. I'll probe it, thanks for the idea :smile:

My guess would be, since the Airboard IR Receiver connectors plug directly into the keyboard inputs on the PC, there is a IR-to-keystroke conversion going in inside the receiver device (ie. it's not a "transparent" device like IRMAN). Which, I believe, means that you could/should use either ther "serial" or "kyboard" plugin to interact with Girder.

One other theory I have is that the Airboard sends out additional IR codes indicating "keypress" and "key-unpress". I say this because I have tried to "learn" the IR codes from Airboar on both my handheld remote AND IRMAN, and neither gives a consistent code for any key other than the top row of non-standard function keys (ie close, cd, video, www, etc), which all give consistent simple codes.

Does this make any sense?? :wink:

As you may know, Silitek has now discontinued the Airboard and has replaced it with model SK-7551. Looking at both keyboards specs, I found that the new SK-7551 may have a feature that the original Airboard don't have: 'Universal IR remote control transmission protocol' (found here: http://home.att.net/~linchi/keyboard/keyboardFrame.htm).

Can this solve the problem discussed here, i.e. keyboard IR receiver able to pass remote control events to Girder ?

Thanks in advance

Sounds like that is the problem they are trying to address....HOWEVER, based on their inability to support my "simple" problem, I gave up on them and went to the Gyration RF mouse/keyboard. I have been delighted with the performance of the new system (ie no "aiming" the mouse or keyboard at the IR receiver).
