    usually power consumption of USB available by reading USB info;
    connect the LCC to PC and run Microsoft USB utility to probe it, it will pull also max current value what the device require

    here is;
    unzip it, then un7z it, then change extension "png" to "exe"

    I don't know what power budget of DTV DVR's USB port(s), but the above look innocent ;)

    Theoretically a PC that's plugged in is required to supply 500mA@5v, while "lower power devices" like a phone are only required to supply 100mA (add 50% to each mA figure for USB3)

    Obviously DVRs are plugged in, so if they followed the letter of the USB spec I guess they should supply 500mA, but there's no one to enforce these USB requirements so I'll bet it only supplies 100mA and possibly supplies no power at all - given that when everything from the H21/HR21 all the way through the HR54 was designed, Directv supported only one thing to be plugged into it, the AM21 which is separately powered. So why would they want to supply additional power they had no use for, that means designing the power supply for a slightly higher peak load; they want to shave pennies off the cost to make receivers not add pennies to the cost.

    The HS17 appears to have been designed to have NOTHING plug into it - it declared no support for the AM21 from day one of pre release testing and the LCC did not yet exist when it was being designed. They must use the USB port for diagnostics otherwise the HS17 would probably not have a USB port at all!

    The H20 supported having a USB to serial adapter connected, which would allow controlling it with serial commands to change channels and the like. I'm not sure if that was officially supported beyond the H20 though, since newer receivers supported TCP/IP and SHEF for such control.

    Just in case, for people who never been close to design/production device with USB port: to get the USB logo, your device must be certified and fulfil all its requirements what an alliance [USB or HDMI or MoCA, etc] put up in specs.

    And if not, can one have an unlabeled port?

    Supposedly, I'm getting an OTA dongle per Tech Support via DirecTV (Not AT&T) Chat, after a recent un-related issue I initially discussed, to replace my failed AM21 on my Genie. At first, he said it would be via a truck roll. Then I indicated I'm not in the testing DMA's for the equipment, so the truck roll would not likely have it in stock. He then said since I have PP, he would drop ship at no cost. I checked my DirecTV account online right afterwards and it showed the details below. "Crossing my fingers it arrives"......

    See attachment.....Looks like their system has it tagged as a RF Modulator, as discussed in the past.

    I wouldn't be so sure … it could be something totally different. The OTA USB tuners (AM-21, LCC, etc) doesn't have any "RF Modulator" components.

    Well, I'm not going to say you definitely won't receive a LCC, but that totally does not sound like it, so lot's of good luck with it ....

    But appears to be just as a ch. 3/4 RF modulator that field techs. and tech. support use to supply for customers who still had old NTSC TV sets without A/V inputs.

    Didn't even know DIRECTV still stocked those ...

    Anyway, keep us informed what actually arrives ...

    You’re probably right, after all it’s AT&T at the wheel now. I have a little bit of hope in that I referenced an AM21 replacement in the chat, and the chat agent typed Local Channel Connector (LCC) in his response to me. We’ll see....

    They supposedly shipped me an LCC. I got two power cords, one for my receiver and one for my AM21!

    I'd really advise those continuing to try an "slip through the cracks" this way hoping to wriggle-out an LCC early. To save time by confirming the CSRs are definitely seeing the model and part numbers posted earlier by grover517 actually on their order screens first before attempting to order.

    Otherwise, tell them forget it as it's just going to end up in a cancelled order or something silly and completely different.

    No, tested it with my RV antenna which is a Winegard Rayzar z1 as well as a AntennasDirect Clearstream 4 max on a pole strapped to my RV ladder which has a much greater range than my RV antenna does. Wanted to see what I could pull in from my location using each, what I couldn't, and compare signal strengths as well.

    Hi All
    After a long talk with someone I could hardly understand, I was told the there is a problem with NBC in non specified areas of USA and until that's cleared up, things are kinda on hold for releasing the LCC.
