The Avid HD I/O Digital Option is an expansion board that adds eight channels each of AES/EBU (supports 192kHz single-wire and dual-wire), TDIF, and ADAT (supports S/MUX II and IV) input and output to the Avid HD I/O audio interface. Dependent on the current configuration of your HD I/O chassis, the expansion option can add additional digital I/Os either as an add-on, or by swapping out existing boards.
