March 2026 SDK, section 2.4.11, pp. 31–33: subdevice pairs; changes may stop streams.
Do not transfer 8K Pro or Quad 2 profiles to Duo 2. Save the mapping before changing it.
Profile by group / active indices / individual connectors or pairs:
Duo 2 half-duplex: index 0 → SDI 1; 1 → SDI 3; 2 → SDI 2; 3 → SDI 4.
Duo 2 full-duplex: index 0 SDI 1 in/key + SDI 2 out/fill; index 1 SDI 3 in/key + SDI 4 out/fill;
indices 2/3 inactive in their groups. This does not confirm autonomous pass-through without an application.
