SD SDI card on DL.3

Hey,guys
I want to know details about the DL.3 SDI card,I wonder if you would like to share some information of that.

1.The DL.3 SDI card is on SD-SDI currently, can I use camera to output the composite video signal with PAL system via BNC to DL.3 SDI?

2.If it does,what is the type(analog or digital) of the signal feeds to the DL.3 SDI card?

3.What is the maximun resolution for the SDI in DL.3?
