Hi folks.

This may well be the wrong group for this question - appropriate
redirection welcome, but UK.DIY-ers seem willing to have a go at most
things, so...

We've been given an old-ish analog mini-VHS-tape-thing Mitsubishi
HS-CX1(B) camcorder, minus manual. On the rear of the unit there is a
mini DIN type socket into which plugs a small box on a flying lead which
provides modulated UHF I/O for picture/audio - just plug into the
antenna socket of any TV/video...

However, I want an unmodulated composite video out. There are, I think,
more pins on the camcorder socket than would be required to provide what
I/O we have - I'm wondering if it's possible to get composite video +
sound from some of the others? Does anyone have a pinout for this device?

It appears that manuals are available for this device, but at a price...

TIA.

PJ.

Ha! yes sorry you want the service manual rather than the operators manual.

Just had a look its 38GBP that is a bit much for an camera thats now
extinct.

Might as well post this site could be usefull for anyone needing a service

Can you open up the modulator and trace the wiring? Since it's a
camcorder, I'd expect it only to carry composite video, stereo sound and
possibly power for the modulator. But it may only provide sound when
playing back.

Earlier cameras which plugged into a separate recorder also had power and
control circuits on IIRC a 10 way. I've got the pin out for those. ;-)

That's plan B. Here goes...

.... later.

Four wires terminating at a socket on the modulator PCB. Each pin is
labeled on the PCB, although the labels are partially obscured by the
socket. They appear to read (with corresponding wire colours):

A (Red)

G (Brown)

V (White)

B (Black)

There's another line of text above - it starts with a triangular symbol,
and then reads, "MTM-1OV-O". I don't know if the '1', and 'O' are
letters or digits. I can trace each wire through to a corresponding pin
on the DIN type connector (it's unlike any I've seen before - PS2-ish in
size, three keys at 120deg intervals (one larger than the other two),
eight pins arranged in a circular pattern).


Since it's a
camcorder, I'd expect it only to carry composite video, stereo sound and
possibly power for the modulator.

Stereo sound may be a bit much...

The modulator unit is identified as a Mitsubishi DAR-M1EB. It claims an
input voltage of 5VDC, 35mA. It also boasts something called an "I/G
system select switch", whatever one of those is... :/


But it may only provide sound when
playing back.

I don't mind that. I'm just not so keen on blowing my video card up by
plugging the wrong thing into it...

Composite video would be around 1 volt maximum voltage. Connect a
voltmeter between ground and each pin in turn looking for something
between 0.3 and 1V that varies with picture content. That might be
video out. Audio might need trial and error connection.

Do you have a multi-meter?

If so, connect the cable to the camera
turn on camera and play a tape (or put it into camera mode!)

Now poke the connections inside the modulator and look for the 5v
It's probably on Red and Black
now measure the -ve from the 5v to the other two connections, one of them
will show about 1v (varying) this is your video signal - the last one is
audio :-)

My guess would be...

A (Red) - +5v

G (Brown) - Audio

V (White) - Video

B (Black) - Ground

But you won't know unless you poke it :-)

Yup. Fluke.

Okay. Will try. *Slightly* concerned about killing the camera, but...

Okay, I get nigh on +5v (+4.96v) on Black with Red as ground. Still with
Red as ground, I get between +0.75v and +1v on white, fluctuating
between the two values as I put my hand over the lens and then remove it.

So my video signal is on Red/White? My PC's video card has an RCA
(phono) input for composite video - Red to the ring and White to the tip?

Any other precautions before hooking it up?

Ahh. As with so many things...

Different PAL versions?

Could be. The modulator has two coax connections - "OUT TO TV", and "IN
FROM ANT", which I assume are just for patching into an existing UHF
feed. There's also a channel tuner, labeled "32 - 40", which I assume is
for setting the output frequency of the modulator, and the "I -G"
switch...

Yup, sounds good to me!
Slightly odd that the 0v is red - you definatly got the meter's probes in
the correct holes!?

Not really, just dont short the 5v to anything!
The brown has to be audio, so you may as well hook that in too!

Yup. Appeared odd to me too, so I double-checked. Black probe in the
"COM" socket of the multimeter, to the black wire, and the red probe in
the "+" socket, to the red wire, gave me "-4.96", on the multimeter.

Cool. I'm assuming I'm going to end up hacking this cable - the
connector manufacturer is Mogami, but I've yet to find anything retail
on either RS, or Mogani's own website (which doesn't appear to work too
well). Ho-hum...

Thanks.

Is this connector an 8 pin one, with a notches at...
12 o'clock (Between pin 1 and 8)
5 o'clock (Between pin 3 and 4)
7 o'clock (Between pin 5 and 6)

Do you have a photo of the connector?

I'd of thought white(signal) and black(ground) would have given you the

Hey up 5v+ to the card I smell smoke. :-(

:-) I have one on my old old old Ferguson Video VHS-C camera :-)

On mine, if you look at the connector on the cable, with the biggest notch
at the top, going clockwise, assuming the pin at 1 o'clock is pin 1...

Audio + = 3
Audio - = 5
Video + = 8
Video + = 7

+ meaning the centre pin on an RCA plug, and - meaning the screen.

Alternatively, you could cut the current cable in half, connect one of these
to the wire with the funny connector on
http://cpc.farnell.com/jsp/endecaSea...=AV10583&N=411

Then put one of these on the modulator...

This is common with trade electronics suppliers - they pretty well all
have a minimum charge/expensive p&p. For small orders you need the likes
of Maplin shops - not that they stock much in the way of electronics these
days.

Don't remember that happening to me. But you can work out the price anyway
by checking their conditions.
