| Post subject: | IR Blaster options - 2 identical devices |
Running R5F27 with a 250 and 150 analog capture cards. Comcast is giving me two converter boxes dc50x Computer (duron 64) has available 1 serial port, 1 parallel port, and bunch of usb ports. So my option are buy: A) 2 port serial card and two ir blasters (any card suggestions?) B) buy Iguanworks USB Blaster I am all the for the easiest option and the prices are near each other. Not a linux guru, so avoiding as much configuration is also important. Any opinions on what to do? thanks |

I don't know which option will be easier, but I'll throw in a third option to consider. You can purchase USB->Serial cables on ebay for $3.50 each = $7.00 for the pair, shipped. If you add serial ports with a PCI card it will require the use of an additional IRQ; I don't think the USB->serial converters use an additional IRQ, thus reducing the risk of an IRQ conflict. I am currently on R5.5, but I used a USB->Serial cables on my R5F27 box in the past to control my x10 transmitter -- I don't recall having to install any special drivers. |

That would be great if it works. But the net and this form say this is does not work, or I am reading this wrong. http://knoppmyth.net/phpBB2/viewtopic.p ... cf956a63d0 http://ubuntuforums.org/showthread.php?t=647983 If you have it working maybe I could get the exact same parts as you. Another option is using the Media Center remote control but not sure if a custom lirc is needed. |

The hardware minor upgrade has got my head spinning. (in addition to making a door stop out of my replaytv) On the fence of upgrading, throwing everything away, going HDTV, or saying game over. I have a Nivida card (5400 or 6300) and older CPU (SEMPRON 3000 1.8GHZ) that might be able to handle playback, but probably not transcoding. A new TV and HDHomerun would be nice, but can not also pull off an entire new myth box as well. |

I'm not using the USB->Serial cable for LIRC so I cannot confirm it will work for the purpose -- I use it for my x10 interface. The threads you linked to suggest it won't -- probably not worth the headaches of trying that path. |

You can also try the: Quote: Double Headed MythTV LIRC RS232 IR Blaster
Two Standard IR Heads connected to one DB9 from http://www.irblaster.info Basicly, you'll need to have each box "listen" for different codes--this is usually accomplished by changing a setting on one of the boxes called "IR Address" or similar. Then you'll need the second set of codes in lircd.conf and a second channel changing script. When you change the channel, both blasters will send the code, but only one box should respond. Disclaimer: I have never had the need to do this, but I've heard it can be done and is not too difficult. |

I looked in that option and the pace dc50 hardware only has one channel. I switched my Replay Tv in to another channel a few year back do to a few conflicting signals with some tuner at the time. The good old show stopper supported 4 channels, and still is downloading tv listing for somewhere paid by someone. The 4 blasters there also blast the signal on all 4 channels as well. The Commander IR has separate channels. I am thing about switching cable provides and maybe just getting allot of tuners to drive the three pvr tuners that I have. The sole dc50 device that has been up for days that I use for live tv viewing locked up today. I dont want to record "Service is temporarily unavailable. Please wait." for hours on end before I notice the box needs to be reset. Yikes my video card is a only a MX 440. Not to thread crap my own thread, but if anyone was doing all over again today, what tv & pvr services would you use? |

Another option albeit a little pricer is: http://www.commandir.com/ It has 4 irblasters and one receiver. It lets you address each device independently. It works with R6. I am having some trouble with the IR receiver, but that my be an issue with configuration file. I also needed to plug in a USB hub between the commandir device and my motherboard to get it to work. But it does work. |

Really they are my only two choices or switch to lower tech analog cable company. |
