Why don't camera reviews cover the data connection to the PC?

    I see no evidence that you're anything other than a deskbound
    specification junkie suffering from delusions of grandeur.

    Here at sci.electronics.repair there are real technicians who
    understand which end of a soldering iron is hot. We also understand
    integrated circuits, ie those square and rectangular plastic thingies
    with lots of shiny pins.

    If you can refute the work of the people at pinouts.ru, people who
    presumably are technicians themselves, then here is your golden
    opportunity to do so. What resistance or voltage do *you* measure on
    the ID pin of a Motorola RAZR charger?

    Highly unlikely that anyone will believe him. He has such a long history
    that anytime he starts up someone points out that he has no idea what
    he's talking about.

    What bugs me is that anyone with an iota of technical competence can
    in a matter of minutes determine the connectivity of a mini-USB cable
    or a USB charger using only a $10 multimeter.

    You are missing the point. A review should point out technical issues.
    We read a review to evaluate whether the gear is suitable for our purpose.

    We can't ask the intelligent question if we don't know what to ask.

    nobody else would be like that, right?

    You're wrong. You can often buy digital multimeters for less than $2 at
    Harbor Freight. I bought ten of them at $3 each for an enrichment day
    science presentation that I did at my son's school on Ohm's law
    (something that a few people in this newsgroup would have benefited
    from, judging from a recent thread on batteries where several people,
    including Navas, demonstrated their lack of understanding of the
    difference between current, power, and energy).

    Hello, 'duck:

    You're quite right. I just noticed that Matt Ion had deleted any
    attribution(s) to this thread's originator ((Pat Cheney), during
    his edited reply to you; the EXIIM cameras in question belong to
    Matt's wife and Pat, actually.

    Oh, well... <g>

    Happy New Year,

    Hello, Pat:

    Yes, I'd responded, before reading your message, concerning the manual.
    Amomg my various Kodak digicams, the V603 is the lone one which has a
    "USB/AV connector." As with your own Casio EXILIM, this seems to be the
    comparatively rare exception, rather than the rule.

    Regardless, it's quite common for digital cameras to use proprietary USB
    cables, from my personal experience. Such a practice is hardly unique to
    Casio (or Kodak, for that matter), and in any event, is nothing to fret

    Happy New Year,

    only if there's a harbor freight store nearby and if it's on sale.
    that's not going to be the case for most people.

    Maybe this will give you an insight into John Navas's business model:

    After many years watching comp.dcom.modems, I saw no evidence that
    John Navas tested any dialup modem on anything other than his own POTS
    line(s). In fact he often expressed his disdain for the testing
    standards and methodologies of others, many of whom used industry
    standard telecoms simulators. Such is the arrogance of the man.

  11. What's more, for the specific purpose of checking out USB connectivity
    and charging you don't even need a good meter, a crap one is perfectly

    but then there are shipping charges, bringing it closer to $10. and
    it's actually a $3 meter, not $2.

    with that insult you concede the debate.

    I'd rather I never met an IEEE-488 interface. :-( ...one off the
    world's most stupid designs.
    HF meters aren't repairable, and Flukes keep working. ;-)

    I have three (one escaped) Fluke 77s and a bunch of HFs. I keep
    the HFs in my tool boxes so they get borrowed. Since I've been
    doing this, my Flukes haven't gone missing.
    Depends on who built the Heathkit. ;-) They did take a beating,
    though there was one resistor in the ohms section...

    Yeah, most of it's only available online.

    How many "large" systems (say, 20-30 devices) have you tried to put
    together. The connection problems with large numbers of devices
    are huge, though I've seen them with only a couple of devices on a
    channel, as well. cablingg gets to be a mess (and you'd better have
    lots of different lengths on hand to play with).

    I have a Fluke PM97 Scopemeter for which I paid AU$2750. Just about
    everything's broken in it. Bad probes, bad batteries (soon after
    purchase), bad AC adapter, bad logic board. Even one page of the $100
    service manual (the power supply circuit diagram) was missing. For the
    past 10 years or so the meter has been sitting in the cupboard. One
    day I'll have another go at repairing it, otherwise I'll stomp on it
    .... again and again and again ...

    No, it would be quite possible to design a custom connector that could
    accept both standard mini or micro USB plugs, or a custom A/V plug. They
    would put the contacts for the AV connections further back on the
    connector. It's been quite common to use dual purpose, dual level
    sockets on ultra-small Japanese notebook computers. Other variations
    have been a USB connector with a small hole to the side of it so an
    external, higher power-consumption, USB interface drive could be plugged
    only into that USB port (and that USB port being able to supply more
    than 500mA).

    There's all sorts of creative ways that they could have handled this,
    but it was cheaper to use an off-the-shelf connector, and order custom
    cables. How many sales do you think they lost because of this custom
    connector? Probably zero.
