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.
