Can anyone prove me wrong? please please :-D How about the simple, low-tech answer: physical isolation. Tape the blaster end to the IR sensor on each box and cover them with duct tape. Put a piece of cardboard between the two boxes so the IR signals don't leak from blaster 1 to box 2. Have the boxes face opposite directions. I could go on, but I think you get the point. Unless your issue is that the blasters are both mirroring each other. But even then, I think you just need to setup lircd to manage them as separate devices. Unless I'm mistaken, the two blasters are on different pins and so can be operated separately by lirc. |

If the cable boxes both have serial ports on them, and you can control each of them individually via serial cable, then you don't need blasters at all. As I understand it, your PC has a single serial port. So that connects to one cable box via serial, then the usb->serial adapter connects to another serial cable which goes to the other cable box. >From there you can use the dct-channel to control both boxes, and just vary the parameter to determine which box you're controlling. No LIRC needed, no blasters needed, no electrical tape, no changing remote codes on boxes needed... -I |
