- I have done this with a very old RGB Display. You have to make a connector
- which connects the following pins on the 15 pin VGA socket to BNC connectors
- for the RGB Monitor.
-
-
- VGA Function
- PIN
- ------- ----------------------
- 1 RED
- 2 GREEN
- 3 BLUE
- 4 (Reserved)
- 5 Digital Ground
- 6 RED Return
- 7 GREEN Return
- 8 BLUE Return
- 9 (Plug)
- 10 Digital Ground
- 11 Monitor Sensor 0
- 12 Monitor Sensor 1
- 13 Horizontal Drive
- 14 Veritical Drive
- 15 (Reserved)

- The RED, GREEN and BLUE should be drawn out as three BNC (I assume your RGB
- monitor uses BNC) connectors. Connect these pins to the signal (centre) of the
- Coaxial cable. Connect the R/G/B Returns to the shield of the respective RGB
- coaxes.
-
- The H and V BNC should be connected to the Horizontal and Vertical Drive signal
- respectively. If I remember correctly, you can use the digital ground as the
- signal return.
-
- In my case, the monitor accepted only composite sync so I ahd to plug to signal
- straight into the board after the sync seperator circuitry.
-
- I have used the same cable with a large screen projector as well.
