AV Device Library Guide
A device block in an AV schematic should describe the hardware accurately enough to validate real connections — and still be usable offline without an internet connection or vendor lookup.
Why device libraries matter in AV drawing
Generic boxes in a diagram tool force the designer to hold all port and protocol knowledge in their head. An AV device library encodes that knowledge into the drawing itself — so when you connect an HDMI output to a DisplayPort input, the schematic can flag the mismatch before the equipment ships.
Ports before pictures
The port map is the source of truth in HTIFA. Visual layout follows the signal topology, not the catalog image. Each port carries its signal domain, connector type and protocol so the AV schematic drawing can validate compatibility at connection time.
Library packs install on demand
HTIFA ships with generic offline devices so every AV drawing starts immediately. Free and Pro library packs add real port maps and hardware metadata for specific manufacturers. Installed packs cache locally — your AV schematics still load and route offline after the first sync.
Custom devices stay flexible
Pack-backed ports preserve their source metadata for validation, while generic and custom devices remain fully editable. If a client specifies unusual equipment or a room needs a project-specific block, add it once and reuse it across every drawing in that project.
