Two new pages distilled from HAI's official OmniPro II Installation Manual 3-2 + Product Specifications datasheet (Quadomated mirror). reference/hardware-specs.md Capacity ceilings (176 zones, 511 units, 8 areas, 64 thermostats, 128 buttons, 1500 programs, 99 codes, 128 messages, etc.), digital communicator + network features, electrical specs with the per-output current caps and the 24-hour battery-standby derating numbers, physical dimensions, environmental ranges, listings, languages, and part-number lookup. The numbers here are the source of every cap in clsCapOMNI_PRO_II.cs and the upper bounds for the protocol's range fields, so anyone debugging "why does my panel NAK at index N" should start here. explanation/zone-unit-numbering.md Appendix C of the install manual, transcribed and explained: how the panel maps physical hardware to its 1-176 zone and 1-511 unit address spaces. Documents the four overlapping families that share the unit number line -- X-10 (1-256, by house code), ALC bus (parallel address space within those slots), physical outputs (257-392), and panel flags (393-511) -- which is why the working panel reports units at index 257+ (sprinkler outputs on the first 17A00 expansion enclosure) and 393+ (named flags) even though only a dozen lights are wired up. Closes a real debugging mystery from Phase 2/3 of the v1+UDP work: OmniClientV1's long-form RequestUnitStatus path (BE u16 start/end) exists specifically to address units > 255, which only happens because of this firmware-fixed address layout. astro.config.mjs Slot both new pages into the existing Reference and Explanation sidebar groups.

| Hardware specs | Omni Pro II controller capacities, electrical specs, environmental ranges, and expansion limits — distilled from HAI's official product spec sheet and installation manual. |
The numbers below are the Omni Pro II controller's hardcoded capacity
ceilings: the protocol's RequestProperties / RequestStatus ranges, the
SystemStatus payload size, the .pca file's fixed-size names tables, and
every cap in clsCapOMNI_PRO_II.cs derive from these. They're the
reason OmniClientV1 chunks polls and uses the long-form
RequestUnitStatus for unit numbers above 255 — see
zone & unit numbering for the address
layout that yields those high numbers.
References for everything on this page: HAI's OmniPro II Product Specifications (part 20A00-2, 2012-10) and OmniPro II Installation Manual 3.2, both available from quadomated.com.
