Each UHFQA in a QCCS requires one HDAWG to establish a connection to PQSC.

DIO Connector

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 DIO port features 32 bits that can be configured byte-wise as inputs or outputs.
