D²B

D²B=Domestic Digital Bus

Pin 10, 12 and 14 was used for a databus by Philips, now called IEC 61030. Not used anymore?

D²B is a multi-master bus. Collision detect with CDMA/CD.

Blanking

Pin 16 is used to select between RGB & composite video. Input impedance is 75 Ω, so use 180 Ω resistor from +5V to activate RGB. This should give +1.5VDC at pin 16. Tip: Pin 9 at VGA connectors is +5V.
