Variables
# UNRESOLVED: source describes settable parameters (volume up/down, keystone, lens shift)
# but no discrete Variable schema; treat as Actions until spec clarifies
Events
# UNRESOLVED: no unsolicited event notifications described in source
Macros
# UNRESOLVED: no multi-step macro sequences described in source
Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings or interlock procedures in source
Notes
Command delimiter: CR (0x0D) only — NO LF. Minimum command interval: 100+ ms. Status read minimum interval: 200+ ms. Some commands differ between X1100/X986 and X1000/X985 models — spec includes both. Volume commands C09/C0A listed without label in source. Temperature read response value marked TBA in source.
