Chapter 7) Video Cameras


7.1) 10-pin Video Camera connector

(From Sam Goldwasser)

This from a JVC camera. The 10 pin connector I know is sort of standard.

I know the 10 pin end is a standard. I have a couple of other cameras that have this connector. I don't know if the JVC end is a standard. There are 5 pairs of signals:

  1. Power and GND
  2. Video and return
  3. Audio and return
  4. Control and return
    I never bothered to figure out what this did (signal that you are taping from/to camera?).

(From Jim Novack)

I recommend that you confirm these, at least for power!! You do not want to be wrong for power. Better yet, use the power jack on the back of the camera to start off.

While the signal pin-out was standard, different manufacturers used a different strategy for pause/go from the camera trigger. I think some used a positive voltage, some used a negative.

There was a technique used that allowed viewing tape playback on the camera viewfinder. I think the same wire that fed camera input to the VCR was used, but the VCR put a DC voltage down it to tell the camera a signal was incoming, not outgoing. I'm hazy on this, it was a while ago!

What you really need is a camera A.C. adapter. These were sold so that people could use these 10-pin cameras with their home VCR. It generally was a small box that contained a 10-pin receptical, a power supply, a small audio circuit (I think) to amplify the camera mic level signal to line level, and video and audio outputs. I have one of these, a Panasonic PK-A789s that I have used with Panasonic, JVC, and RCA cameras. Check with video shops-they might have one gathering dust. Watch out for anything from the pre VHS era (before circa 1977). I remember that Sony, and others, used the same connector for the cameras for their "Porta-Pak" reel to reel and U-Matic decks, and the pin-out on these was different-a sync signal was fed to the camera, for one. They also made A.C. adapters for those cameras (Sony's was called a CMA-2--why do I remember these things??) Avoid these because they would probably fry your camera.

7.2) Quasar video camera pinout

(From: Mike Turner mike.turner@johnabbott.qc.ca))

  1. Video out (REC)/in (PLAY)
  2. Ground for pin 1
  3. Not used or tally
  4. Ground for pin 5 or serial clock in (depends on camera)
  5. Audio in, standby or audio out (2)
  6. Remote pause
  7. Audio out
  8. Ground for pin 7
  9. ground for pin 10
  10. +12 volts DC

I expect you will use only pins 1,2,7,8,9 and 10


Chapter 8) TV Connectors


8.1) SCART / EURO-AV

(From Gerald Evans)

The pins have the following functions:

  1. Audio out B
  2. Audio in B
  3. Audio out A
  4. Audio ground
  5. Blue video ground
  6. Audio in A
  7. Blue video
  8. Function switching
  9. Green video ground
  10. Comms data line 2
  11. Green video
  12. Comms data line 1
  13. Red video ground
  14. Comms data ground
  15. Red video
  16. Blanking
  17. Video ground
  18. Blanking ground
  19. Composite video out OR synchronisation out
  20. Composite video in OR synchronisation in
  21. Common ground

The pin numbering on the plug is as follows:

Note: This is as viewed from WIRING side.

Personally, I think SCART connectors are dreadful things. I mean, who really wants a 20 pin monster when only about 3 or 4 are ever used in any application. But it seems they are being forced upon us!

I think most VCRs just use the composite video (in+out) and the two sound channels (in+out sterio). By the way, quite a common fault with VCRs is that the scart socket gets disconnected from the PCB inside the machine. I have fixed 2 VCRs with this problem. It is not surprising really, because the leverage on the huge plug must be quite large if you pull it out carelessly etc.

The quicher SCART dies, the better, IMHO.

Here is the SCART or EURO-AV or PeriteleVision Connector:

8.2) SONY RGB MULTI INPUT (found on KV-25XBR TV's)

34-pin male connector, looks just like a floppy drive connector.
