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 http://www.dspace.com/en/inc/home/products/hw.cfm 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 http://www.dspace.com/en/pub/home/products/hw/modular_hardware_introduction/i_o_boards/generating_and_capturing.cfm

this is the AD board http://www.dspace.com/en/pub/home/products/hw/modular_hardware_introduction/i_o_boards/a_d_boards.cfm

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: http://www.dspace.com/en/inc/home/products/hw/modular_hardware_introduction/modular_panels.cfm

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