SDI mod pinouts on a denon 2900

Htguy · 9th March 2005, 03:10 PM

Hi,
I am in the process of adding an SDI output on my denon dvd2900 player. I know the pins start on left end of the ribbon connector, so I just want to see if anyone knows if data 2 goes where I have the brown wire inserted, and then data 3-9 follow in order?

Thanks

This is how the connector looks

Hi,
Thanks for the diagram, it was a big help to make sure I got it correct. I am still a little fuzzy on where to connect the clock and the grnd lines from my sdi card.

Thanks

The 27Mhz video clock is on pin 13 refrerred to as vclk. I would take gnd close to the clock ie pin 12 and 14 or better still directly off the main board.

Hi,
Thanks for all your help. I got my sdi output working last night and it is working well.

Hi,
I am thinking about more upgrades to the dvd 2900 and I was wondering if some one could help me. I am thinking about making a new power supply for the audio and/or video boards. So far two of the pins seem to not have a dc voltage on them. Does some one have a schematic that would show the voltages that should come into the 5 pin (video) and 4 pin (audio) white molex connectors?

Also, does someone have a schematic for the opamps that feed the front right and left?

Thanks

God bless...

Ps. Thanks for all your help so far A8. (I'm guessing that A8 refers to you driving an Audi A8, and if so, nice car!)
