Difference between RAPID-NI-V2007 and RAPID-NI-V2107 boards

Hi, dear colleagues!

Could You clear about difference between RAPID-NI-V2007 and RAPID-NI-V2107 eval boards in hardware or software domain. I read datasheet http://www.analog.com/media/en/technical-documentation/data-sheets/RapID-Platform-Network-Interface-with-REM-Switch.pdf but didn't find difference between them. The point is the my customer want to use UART connection between processor and REM switch basically, but then he plan to try use a parallel interface. Can he use a RAPID-NI-V2007 for this?

Thanks!

K.
