I've got KnoppMyth running perfectly. However, I thought it would be cool to get an IRBlaster working so I wouldn't have to deal with my cable box remote. Here is my setup:

Hauppauge PVR-350 with silver remote
Scientific Atlanta Explorer 3250HD cable box
IR Blaster from www.irblaster.info - RS232

Could someone help me out and run through the setup completely noob friendly? I have looked around the forums and even asked Uncle Google several times, and I've found several things that sound very interesting. The problem is that I do not know enough about *nix to set this up correctly.

Any help would be greatly apprecited! Thanks in advance.




EDIT: In trying to get this set up, I ran mythtv-setup and put the location for remote channel changing (/etc/irblaster/channel_change.sh) and now all I get is snow on the TV. No channels, no sound. Any ideas?

No ideas? Any help at all is welcome...

Good!

Here are some links I got from digg.com that should help you learn more of the UNIX side of things:
http://www.pixelbeat.org/cmdline.html
http://www.suseblog.com/?p=141

In general, if you post a question that doesn't say what you tried, or where you got stuck, it's unlikely you'll get a response. So read the contents at those links, try out the HOWTOs you found on getting the IR blaster working, and then see if you still get stuck.

Good luck!

Well here goes...I'm going to try to explain where I got stuck. I was following the guide found here: http://losdos.dyndns.org:8080/public/my ... _LIRC.html

And got almost done with stage 2. My problem came in where it started giving different instructions for Fedora users. Not knowing any different, I tried the steps it gave me here: http://losdos.dyndns.org:8080/public/my ... dora_users and again got stuck. There is one more link for Fedora FC3 users, but that page is down.

Are these steps accurate to what should be done to get this working? Is this even a good guide to follow?



EDIT: More specifically, I get to the point where the tutorial tells me to run

The error I get is

I just did some checking on my own, and KnoppMyth should have asked you if you have an IR Blaster when you installed or upgraded. Did it not do that?

In any case, you may be better off trying to run /usr/local/bin/irblaster.sh as root to set up a serial IR blaster.

When I run that, is it supposed to do more than:

OK having picked option 7 you need to put the appropriate code file for you cable box in the right place (/etc/ledxmitd.conf). I'm prety sure this is doument in the irblaster stuff on the wiki, or the pages it links to. IRBlasterHowTo Searching for the string "ledxmitd.conf" here in the forums may get you more direct info like exactly where to find the code files to use in already installed.

Thank you very much for the resonses!

Ok, I have gotten the file from here: http://lirc.sourceforge.net/remotes/

It is in the etc folder, so the path to it is /etc/ledxmit.conf

When I run /usr/local/bin/irblaster.sh I still get the same thing. With all this done, when I run mythtv-setup, I put channel_change.sh in the external channel change command field, but when I reboot, all I get is snow. I cannot change channels, and there is no sound.

I guess there are more steps...Any ideas?

Ok, here's an update. I just got out my digital camera to see if the IR blaster is even working. When I point any IR remote control at it, you can see the "light" blinking. When I point the camera at the IR blaster and the hauppauge remote at the IR receiver, I get no blinking in my camera. Is it possible my blaster is defective? Right now, I am doubting that, I think it's just not configured correctly.

When the IRBlaster questions were added to the knoppmyth installation process, things were arranged slightly differently than in most howtos that you find. This allowed the same compiled version of lirc to be used for the blaster and any remote that you may have. Thus there is no instance of lirc with all of the symbols replaced with ledxmit.

The config file you need should be placed in /etc/irblaster/irblasterd.conf
You should then be able to use the channel change script /etc/irblaster/channel_change.sh.
The file /etc/irblaster/hardware.conf defines the serial port that the blaster is attached to (which should have been set up for you when you ran irblaster.sh).
Then you need to set the channel change script in mythtv-setup and make sure that all of the channels have frequency ids specified (this may happen automatically for datadirect users? - not here in australia though).

Any ideas why my IR blaster would not even be emitting a signal? If I use my digital camera, I can see the signal coming from any IR remote control, but when I look at my IR blaster, nothing.

Anyone?

Have you got it plugged in to the right com port? Have you tried using irsend with SEND_START instead of SEND_ONCE so that it sends a continuous stream of codes? The brief flash that you get by sending a single code may be hard to detect. When you use another remote, it will be sending the code many times.

Greg, if I open up my box to the net, would you be willing to SSH in and see what the deal is?

No problem. Doesnt mean i'll be able to work it out, but I'll give it a go. I'm off work sick today, so if you give me the details, I can get right on it.
