3.1) VGA/SVGA

(From Sam Goldwasser)

Original VGA (31.5 KHz - 640x480)
SVGA (35-37 KHz - 800x600) 15 pin sub D:

			  				         6
 1 Red (Analog)   6 Red   Return    11 (ID0) GND (Color)     11. . . 1
 2 Green (Analog) 7 Green Return    12 (ID1) NC (Color)        . . .
 3 Blue (Analog)  8 Blue  Retuen    13 Horzontal Sync          . . .
 4 Reserved       9 No Connect      14 Vertical  Sync          . . .
 5 Ground        10 Ground          15 No Connect              . . .
                                                             15  10  5
Note: Monitor ID Lines ID1,ID0=NC,G for color; G,NC for Mono. ID0 only may be used.

Mono VGA is similar using only the Green Video and Return.

3.3) VGA (VESA standard)

(From Bob Myers)

Note that many of the pins shown above as "no connects" (actually, these were sometimes used as monitor ID bits by many manufacturers) are now defined under the VESA Display Data Channel standard. This standard provides two protocols for display ID and control, including support for the full ACCESS.bus interface. The current definition of the "VGA" pinout per the DDC standard is:

			  				             6
  1 Red (Analog)   6 Red   Return       11 Monitor ID0 (opt.)    11. . . 1
  2 Green (Analog) 7 Green Return       12 Data (SDA)              . . .
  3 Blue (Analog)  8 Blue  Return       13 Horzontal Sync          . . .
  4 Reserved       9 +5 VDC (frm host)* 14 Vertical  Sync          . . .
  5 Return        10 Sync return        15 Data clock (SCL)*       . . .
                                                                 15  10  5
Those signals marked with an asterisk would be supplied by the host only if the host supports the DDC2 protocol (I2C or ACCESS.bus).

Monitor ID bit 0: reserved
Monitor ID bit 1: GND = mono, OPEN = color
Monochrome monitors use the green signal

3.5) Somewhat standard 9 pin VGA

(From Sam Goldwasser)

For analog VGA/SVGA measured based on my VGA to 9 pin adapter. This is pretty standard as the NEC Multisync II and others use the same pinout:

Pin 1: Red Video
Pin 2: Green Video
Pin 3: Blue Video
Pin 4: H Sync
Pin 5: V Sync
Pin 6: Red Return
Pin 7: Green Return
Pin 8: Blue Return
Pin 9: Ground

NOTE: IBM PGC assigns pin 4 to Composite Sync and pin 5 is a no-connect.

(From Sam Goldwasser)

BTW, don't use an EGA 9 pin extension cable to connect it to VGA. While this will work, the wires are not shielded or the wrong wires and you will get ghosting and ringing at vertical edges. I constructed mine using proper 75 ohm coax for the RGB and H and V sync as well (though it is not needed for the sync).


3.6) EGA (CPD-1303)

(From Brian Smither)

According to the CPD-1303 user guide:

   Pin:        1   2   3   4   5   6   7   8   9
   Analog     GND GND RED GRN BLU GND --- H/HV V  *
   DIG/NORM   GND GND RED GRN BLU GND --- H/HV V
      /D1     GND GND RED GRN BLU INT --- H/HV V
      /D2/CGA GND GND RED GRN BLU INT --- H/HV V
      /D2/MDA GND GND --- --- --- INT GRN H/HV V
      /D2/EGA GND  r   R   G   B   g   b  H/HV V

   r-g-b is secondary colors for 64 color EGA

* Sync on green automatic if H or HV is not assigned to pin #8.

SYNC: any polarity.
Vertical size depends on vertical frequency and can be adjusted manually.


3.6.1) DB9 to DB15 cable

(From Brian Smither)

A 9-pin (monitor) to 15-pin (video card) cable can be built as follows:

     9-pin F         15-pin M
     -------         --------
      1,2,6  ---------  5
        3    ---------  1
        4    ---------  2
        5    ---------  3
        8    ---------  13
        9    ---------  14

This adapter will NOT permit you to run a standard VGA monitor from a MGA/CGA/EGA video card as the signal levels and scan rates are not compatible. It only applies to the CPD1303 and similar monitors.


3.7) EGA - TTL

(15.74-21.85 KHz) DB-9 pin:

 1 GND                    6 Secondary Green Video/Intensity
 2 Secondary RED Video    7 Secondary Blue Video
 3 Primary RED Video      8 H Sync TTL Positive
 4 Primary GREEN Video    9 V Sync TTL Negative
 5 Primary BLUE Video

(From Sam Goldwasser)

BTW, don't use an EGA 9 pin extension cable to connect it to VGA. While this will work, the wires are not shielded or the wrong wires and you will get ghosting and ringing at vertical edges. I constructed mine using proper 75 ohm coax for the RGB and H and V sync as well (though it is not needed for the sync).


3.8) CGA - TTL

(15.75 KHz - 320x200 or 640x200) DB-9 pin:

 1 GND                    6 Intensity
 2 Unused	          7 Unused
 3 RED Video              8 H Sync TTL Positive
 4 GREEN Video            9 V Sync TTL Positive
 5 BLUE Video

3.9) Monochrome - TTL

(18.43 KHz - 720x350) DB-9 pin:

 1 GND                    6 Intensity
 2 Unused	          7 Video
 3 Unused                 8 H Sync TTL Positive
 4 Unused                 9 V Sync TTL Negative
 5 Unused
(From John Bunting)

Pin-outs of that 9 pin monochrome adapter:

pin 1  ground
pin 2  ground
pin 3  N/C
pin 4  N/C
pin 5  N/C
pin 6  Intensity
pin 7  video
pin 8  horiz sync
pin 9  vert sync

6.1) 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:

__________________________________________
\                                         |
 \  20  18  16  14  12  10  8   6   4   2 |  (case=21) 
  |   19  17  15  13  11   9   7   5   3  |
  |_______________________________________|
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.

7.1) What is the pin out for ...?

(From Ralph Valentino)]

This is a list of the pinouts to the more common PC hardware interfaces. It is by no means complete. While I have taken care not to make any mistakes, I urge you to take caution when using these tables. Also, please keep in mind that these are only tables, they are not a guide to hardware hacking and do not attempt to explain drive capabilities, signal timings, handling care, or other interface issues. As always, make sure you know what you're doing before you start hooking wires to your PC.
