compatibility w/ dSpace board

Hello, I need to connect Arduino mega2560 with a dSpace board (digital I/O and A/D boards), 10 V coaxial connectors. How to solve the electronic compatibility with arduino digital and analogic ports? thank you

dSpace board? What is that? Post a link?

The dSpace boards are PCI/ISA interface boards for plugging into a computer. Are you referring to the dSpace connector/LED panels?

Sorry, i forgot to post the links

this is the digital I/O board

this is the AD board

and yes, i'm referring to the connector(/led) panels to communicate with the processor board. To be more precise, buses have BNC or Sub-D connectors:

then my problem is to choose between bnc and sub-D ports. and how to resolve the difference in voltage
