DIO Port

The DIO port is a VHDCI 68 pin connector as introduced by the SPI-3 document of the SCSI-3 specification. It is a female connector that requires a 32 mm wide male connector. The interface standard is switchable between LVDS (low-voltage differential signalling) and LVCMOS/LVTTL. The DIO port features 32 user-controlled bits that can all be configured byte-wise as inputs or outputs in LVCMOS/LVTTL mode, whereas in LVDS mode, half of the bits are always configured as inputs. For more specifics on how the user-definable pins can be set.
