Safety

confirmation_required_for:
  - power_off
interlocks:
  - action: power_on
    condition: "While power-on processing runs, projector accepts no other commands."
  - action: power_off
    condition: "While power-off processing and cooling run, projector accepts no other commands."
  - action: lens_control
    condition: "Continuous plus or minus movement must be stopped by sending DATA02 00h."

Notes

Commands and responses use hexadecimal byte notation. ID1 is projector control ID, ID2 is model-dependent code, LEN is data length, and CKS is low-order byte of sum of all preceding bytes. Command failures return ERR1 and ERR2; source lists recognition, unsupported-command, invalid-value, unavailable-state, authority, and hardware-related errors.

Picture, sound, and onscreen mute can be cleared by input or video signal switching; sound mute can also be cleared by volume adjustment. Lamp 2 selection applies only to two-lamp models. Usage-time data updates once per minute even when returned in seconds.

summary: "All 53 spec actions matched with exact command codes in the source; transport parameters verified; source command inventory matches spec coverage exactly. (5 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "source is generic projector command reference; model-specific command support and model code are not stated."
- "model-specific ID2 value not stated in source"
- "unsolicited notifications not documented in source"
- "no multi-step macros documented in source"
- "model-specific ID2 code, supported-command subset, input codes, aspect values, eco-mode values, sub-input codes, and firmware compatibility require supplementary model documentation."
