SDI CARD

[Jigman32]

Anyone have any idea why I can recieve data but not send to my NT8D41 Quad serial data interface paddle board? I have tried DTE/DCE and different buad rates.

The paddle cards are original to the switch.

The DB9 on the IO panel that comes off the ribbon cable connected to the paddle board has a custom pinout. I've recently posted a complete pinout for this application, look through the last couple weeks of posts for complete end to end pinouts of a paddle board.

Thank you johnpoole, pronei and ghtrout. It was the way the paddleboard pinned out. Turns out that 6 on the paddleboard is the recv not 3 like it usually is. So 6 on board goes to 3 on dumb term.

I found this info at

Thanks to all the other who tried to help too.
