Q-SYS I/O Peripherals

Editable Q-SYS I/O peripheral schematic presets (I/O-USB Bridge, DCIO, DCIO-H, NM-T1). Drafting templates, not manufacturer-certified data. Note: DCIO-H ports mirror DCIO; the HDBT extension is approximated with hdmi-a connectors and flagged for review against the official spec sheet.
