Casio camera serial cable schematic?

[Ken_B]

I've been trying to get a Casio QV-770 to communicate with my computer via
IrDA, but no programs I've installed seem to recognize the camera.

None of the apps have an option for the "Virtual Serial" port the IrDA
software set up. Just the standard ports.

I didn't get the serial cable with it, which connects from a 2.5mm plug to
the 9-pin serial port.

So does anyone know the wiring on these cables? In other words, where would
the ring and tip of the 2.5mm plug connect on the serial port?

Thanks.

Ken

PS: This might be a stereo jack. I found some diagrams for other cameras
that were.

Hi from another Ken

I don't have a Casio; but perhaps the pin-outs
from my old Olympus will get you started. It
checks out the same as our very old Ixla, too,
so perhaps there's a standard.

Here's how it works, but if the pin numbering on
a db-9 is the same as this, then it's purely
accidental. These ones are molded, so...

Holding the molded plug in my hand, looking at
the female holes into which I can stick a test
prod, and thinking of it thus:

1 2 3 4 5
6 7 8 9

then the tip is 4
the ring is 1
and the sleeve is 3


Hope this helps you get started... good luck

Take care.

Ken

I just found a diagram for an Olympus, and it matched your diagram with one
small difference: the pin numbers were reversed. I think your pin 5 should
be pin 1.

I'm going to give it a try. Thanks.

Hi...


OK, but remember that the diagram you found will be
the "real" db-9 numbers, that is, the numbers printed
on the back shell of the connector.

Mine is molded, hence I can see those numbers,
which is why I had to number and diagram them the
way I did.

Hopefully, once you buy a female db-9 and look at it,
mine and the other will be the same

Take care.

I had an old Oly' which was aquired without the serial cable (but it used a
DIN plug on the camera end). I ordered a cable which didn't work.
Apparently they changed the standard after the first couple of models.
After trying in vain for about a year to find the correct cable--or the
pinout--in frustration I plugged a 'null modem' adaptor in between, and it
worked like a champ.

Hi,

The cable you require is not just a wire with DB9 at one end and the
stereo plug at the other; it has level shifting (TTl-RS232)
electronics inside too.

There are a number of designs available on the internet. Incidentally,
the same cables also work with Casio's Boss series digital diaries.

If you are interested, mail mee off list, and I shall send you the
circuit.

*Do not attempt a direct camera to PC connection!*

Hi...

OK, now you have me real real interested.
Casio has invented "unpowered electronics?"

I'd love to see what you speak of; can you please
give me a url?

Hi...

Not quite; the power is 'stolen' from the handshake signals on the
PC's RS232 port.

You could take a look at

My personal favourite (the easiest to build, IMHO)version seems to
have gone off the web, the URL doesnt seem to exist. I do have the
downloaded schematic, though.

These circuits power themselves from the serial
port. Just like a serial mouse.

I've built one of the serial interfaces for a
Casio personal organiser, it uses a MAX232 chip.

However this was NOT compatible with my old
Casio camera, for reasons only Casio know.

No, the electronics is powered from the serial port.

These circuits do not produce the negative voltages required by RS232,
but will probably work in most cases. Anyway, they work for me.

http://home.t-online.de/home/milan.urosevic/homepage.htm

These IC based circuits risk drawing too much current from the RS232
pins.

have gone off the web, the URL doesnt seem to exist. I do have the

Here's another interesting Casio cable project I found:

I'll try it when I accumulate the proper parts.
