    DON'T try to hardwire it directly! You could burn out the circuitry on one or both of the boxes. That port on the DCX3200 is almost certainly for an external IR sensor so that you can put it in a cabinet, and the port on the TiVo is for driving IR transmitters.

    You would need something like the custom cable that ggray designed for the Comcast DTA boxes, but made for the Motorola box.

    Potato and pen.
    Seems to me that an IR port would be an IR port, whether for a receiver or a sender. The receiver sensors should all be wired the same, the senders should all be wired the same.

    Ggray's cable might work with a Motorola box too. Can someone clarify?

    When you're driving an IR LED for a remote control the goal is to push as much current through it as possible to get a strong signal. It's typically raw power supply voltage (through a transistor to switch it on and off) to the LED and then to ground through a current limiting resistor. 100mA per LED isn't uncommon.

    A receiver is either a dedicated chip made by someone like Vishay, or just a phototransistor sensitive to IR that's used to switch the input to other delicate components that decode the signal.

    I'm not saying it could never work with a straight cable, but it would be like wiring the speaker output from your subwoofer directly to the audio input on your TV.

    This would be very helpful to know. Has anyone tried it? Thanks for the thoughts!

    Insight Cable just brought out a Digital Transport Adapter and it was a Thomson DCI104 model. You won't find the name Thomson anywhere in the literature or on the box but that is what it is. This info will come in handy if you have to setup an IR blaster like I did.

    All,

    I'm helping my parents configure their Tivo Series 2 to work with the new digital converter their local cable provider (Atlantic Broadband in southwestern Pennsylvania) has given them. The box is the Cisco DTA50.

    It's an oft-told story, as I gather from perusing the forums here, but a combination of Tivo and Atlantic support have gotten us only to the point where we use the IR blaster to change the channel successfully only up to channel 9. I believe this is mostly because no one (Tivo, Atlantic, Cisco) knows the correct IR code for this particular box. Only IR code 00018-A/B/C allow us to change the channel as described. Of note, the DTA50 does have an "IR in," to which a receiver is presently connected. This is towards what we aim the IR blaster.

    I'm sure I don't have to tell you all, but trying to figure this out has been a real headache and time-sap. Any advice anyone can provide is very much appreciated.

    J.P.

    Well, why isn't it? Seems like a good candidate.

    Every DTA that I've seen (Comcast, Motorola, Scientific Atlanta, Thomson, Pace, etc.) uses the same IR code no matter who built it. You might give 10104 a try.

    Unfortunately, we tried 10104-A/B/C early on at the suggestion of Tivo support. I just retried it as well. No such luck.

    How much do we have to worry about the sensitivity of the blaster distance to the IR receiver? We are typically securing one of the two blasters 1-1.5" away from the receiver, as recommended. Incdentally, it is about the size of my thumb and does not easily accommodate both blasters. I keep the other blaster away from the receiver or point it at the DTA.

    Also, any other IR code suggestions?

    J.P.

    Okay, now I think I know what the problem is. The DTA50 and DTA70 operate at an IR frequency of 57 KHz. The DTA30 and all of the other ones I've seen operate at 38 KHz like most remote controls. I would be surprised if it didn't use the same XMP protocol, but that's just a guess. XMP is notoriously hard for even high-end learning remotes to get right.

    The current TiVo IR database only has a few codes that use a frequency that high, and none of them use XMP. I would open a ticket with customer support so that they can get on the job of adding it, but in reality your best bet for now is to pay the rental fee for a full featured cable box that is known to work with TiVo's existing database.

    What codes work with a General Instruments SFT2 cable box?

    Will only the IR cable work with this box or does the 9 Pin Serial cable work? The box has the serial port, just not sure if it works.

    Does anyone know if there are any Dish hi-def receivers that will work with the IR blaster on a series 2? Don't want to give up the Toshiba RS-TX20 (although it can be maddeningly slow to respond nowdays), but I am thinking of pressuring Dish for a free upgrade to hi-def. Have a new 32" 1080p Panasonic and it would be nice to use it for something high definition... I understand the recordings would still be SD but at least we would have the option of watching live tv in hi definition...

    It SHOULD work, but be sure to go into the Dish setup menu and set the IR remote control code to the lowest number (0 or 1).

    Need some guidance, novice to Tivo and Linux

    Trying to setup my Tivo Series 2 TCD24008a for DN Satellite box and a Sony SAT_HD300 Digital Receiver for digital TV stations. Software version: 7.2.2-oth.01-2-140

    Either can be set to receive on RF TV input or RCA input. Ability to change channels via IR connection would be a bonus but not really required.

    Do not know what selections to use to setup the Sony SAT_HD300 for digital TV stations, 2.1, 4.1, etc.

    Any and all help will be appreciated.

    You're paying for a DirecTV subscription and a Dish Network subscription?

    No DirectTV, just want to use the STB for the ATSC digital tuner since the Tivo box only has a NTSC tuner. Since the digital tuner is on the STB, I do not know a way to scan for the channels to get that list into the Tivo. The STB can scan for all the digital channels but it has no channel guide. All I really want is to get the digital channel list into the Tivo guide.

    I don't have the satellite box experience to give you a definitive answer.

    Instead of burying your question at the end of this thread, go to the parent forum, the TiVo Help Center

    http://www.tivocommunity.com/tivo-vb/forumdisplay.php?f=4

    and start a new thread and maybe you'll get noticed better by someone who can actually answer your question.

    Thanks, should probably just ask how to get an OTA Digital Channel list into the Tivo Guide.
