Product-specific answers based on available technical information.
Connectors 0–3 each expose four 8-line ports. DIOPORT 0 covers lines 0–7, DIOPORT 1 covers 8–15, DIOPORT 2 covers 16–23, and DIOPORT 3 covers 24–31.
No. NI requires digital outputs to be written either as ports or as lines, rather than mixing both configurations.
NI lists the SHC68-C68-RDIO2 cable and SCB-68 HSDIO connector block.
