I have now been searching, reading and trying new things for a few days and can get nowwhere at all getting my irblaster to work.

I have the serial port version- shown here.

I have tried everything I can think of with no success.

At this point, I am sure I am doing something pretty stupid wrong, but have given up on going it solo.

Currently I have an led connected to the same pins on a serial port conector, and I know it can light up- at first it was lit constantly, which from one document makes me think it was wired backwards.
With the wires reversed, I get no light at all, no matter what commands I try and send.

I am using lirc to receive signals through my Hauppage pvr350, and this works perfectly.

I have run the irblaster.sh script and tried both ports and every remote listed- none will allow me to send a code which actually makes the led light up.

I can restart irblasterd without errors, but if I stop and start, I get a message stating that lirc_serial can not tell which device to use.
Module is loaded and I do have lirc0 and lirc1 in /dev.

I've read all I can find, here and elsewhere and can't get it.
I'll try just about anything besides high explosives or fire.

Hmmmm. I was hoping to have had at least a couple of suggestions by now.

Seriously- any ideas that might help, please say something!

Have you checked that your serial port isn't disabled in the bios or something?

LEDs only produce light when they are connected in the right direction. If you got light with your first setup, then that was the correct orientation. Now the bad news. A backward connected diode is a short circuit and you may have damaged you serial port. Trying connecting the LED back the way you had it at first and see if it still lights up. Hopefully nothing got fried.

Assuming it still works, what pins are you using on the serial port?

Ok, so I had a bad "how-to" apparently.

Obviously, I am not really all that knowledgeable about electronic components. lol
I will admit that my guess as to why that MIGHT have been accurate was if signals were bidirectional or some such....haven't messed much with serial ports at all.

As for the port itself: it is enabled in BIOS and while I have not yet checked funtionality with any other devices, I think I have an old serial mouse around somewhere.. I will verify that it DOES in fact work, with something.

As for the pins I used: I copied the IRBlaster exactly- pins 4 and 5. (These were also the ones specified in the HowTo.)

Not sure about the port as yet- watching a movie right now- but even if that one IS damaged, there is another. And I have more computers.

I bought the same IR blaster and haven't gotten it working with my Hughes DirectTV receiver. I also have lirc working via my Hauppage Silver remote though.

Just an update, since I recently began messing with my system again.

I never did get the irblaster working, unfortunately.

I did get a CommandIR kit however, and it works flawlessly.
I can now control STB and TV as well as the Knoppmyth box.

Remote codes are easily sent to either external unit and setup was a breeze.
The CommandIR unit was NOT cheap, but I have to say that it was worth my money, as much as I hate parting with dough.

Has anyone gotten the IR Blaster from http://www.irblaster.info/#RS232_IR working with the Verizon FIOS TV's Motorola QIP2500-3 STB? If so what STB did you select during initial knoppmyth setup or did you manually change the lircd.conf file. If you manually modified files could you let me know what files us changed to get it working?

Thanks.

Mine is not working with an IRBlaster, but with the CommandIR unit, but some of what I did may be of help-

Namely, I used irrecord to capture all of the signals from my the stb's remote, and use those to send the signals to the stb.

I added that setup to my LIRC config, and with the emitter I have, simply use commands to get irsend to use that section of the config-

from the command line it would go something like:
irsend fios 33

(fios being the name of the relevant portion of the LIRC config)

I would need to check the exact setup again to be sure that is 100% accurate, but need to head to work now...

Hi.

I was able to get this to work using the serial IR Blaster and selecting the Motorola DCT2000 as my STB (even though my real STB is a QIP2500-3 the codes seem to work for all functionality I have tried so far).

The main thing for me was I had to redo my Auto Upgrade and comment out the Serial Mouse in the xorg.conf prior to restarting X. For whatever reason if I commented out the serial mouse in xorg.conf after the auto upgrade was completed and than restarted X it didn't seem to work.

Thanks.

Actually it's the opposite, a backward connected diode will appear as an open circuit until you hit the breakdown voltage, which ain't gonna happen here. Hard to do any damage just from that.
