Variables

# UNRESOLVED: volume/micvol query returns value but range not stated in source
# UNRESOLVED: contrast/brightness/color/sharpness query returns value but range not stated in source

Events

# No unsolicited notifications described in source.

Macros

# No multi-step sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: power-off during cooling period behavior not specified
# UNRESOLVED: lamp safety interlocks not documented

Notes

• Command format: <CR> is ASCII 0x0D (carriage return). Commands wrapped as <CR>*<cmd>=<value>#<CR>.
• Echo behavior: projector echoes the sent command then responds with uppercase result. Ready prompt is > (0x3E).
• 5-second inactivity timeout: if no command sent after connection, projector responds 0D 0A 00.
• Error responses: Illegal format (bad syntax), Unsupported item (valid command, unsupported on this model), Block item (valid command, blocked by current state).
• Block item and Unsupported item not available in power-saving standby mode (< 1W).
• Status queries and power-on command work in low-power mode (< 0.5W).
• Case-insensitive input; responses are uppercase.
• Dual-lamp commands (dualbr, dualre, single, singleeco) marked with 雙燈 (dual lamp) — may not apply to all TH963 variants.
• Source notes that "functions will vary from model to model" — some source/audio/aspect values may not apply.
• Broadcasting read command lacks trailing # (possibly a typo in source): <CR>*broadcasting=?<CR>.
