Summary

Sharp/NEC projector control spec derived from the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Covers RS-232C serial and TCP/IP (wired/wireless LAN) control of power, input switching, picture/volume/mute, lens, shutter, lens memory, eco mode, PIP/PbP, edge blending, and a broad set of status queries using a binary hex command frame with a trailing checksum byte.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # auto-negotiable per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # full duplex stated; hardware flow lines (RTS/CTS) wired in pinout
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred from POWER ON / POWER OFF commands
  - routable       # inferred from INPUT SW CHANGE command
  - queryable      # inferred from numerous status request commands
  - levelable      # inferred from PICTURE/VOLUME/LAMP adjust commands
  - mutable        # inferred from picture/sound/onscreen mute commands

Events

# UNRESOLVED: no unsolicited notification events documented in source.
# All status data is obtained via explicit request commands.

Macros

# UNRESOLVED: no multi-step sequences described explicitly in source.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    note: "While powering on, no other command is accepted."
  - command: power_off
    note: "During power-off (including cooling time), no other command is accepted."
  - command: lens_control
    note: "Error code 02h 0Fh = no authority; 02h 0Dh = power off rejects command. Shutter/lens require powered-on state."
# UNRESOLVED: source does not specify voltage/current/power specs, fault recovery sequences, or full power-on sequencing requirements. Error bitmasks indicate fault detection (cover, fan, temperature, interlock switch open) but explicit safety interlock procedures are not documented.

Notes

  • Command frame format: commands are binary hex sequences. Request frames omit <ID1> <ID2> in this manual's compact notation, but responses include ID1 (control ID), ID2 (model code), and CKS (checksum). Checksum = low-order 8 bits of the sum of all preceding bytes (including any ID bytes present in the transmitted frame). See worked example in source §2.2.
  • Cooling lockout: after POWER OFF the projector cannot accept commands until the cooling interval completes; callers must retry.
  • Mute auto-release: PICTURE/SOUND/ONSCREEN mute is automatically cleared on input-terminal switch, video-signal switch (and volume adjust for sound mute).
  • Lamp query scope: LAMP INFORMATION REQUEST 3 returns eco-mode-adjusted values; remaining life is negative if the replacement deadline is exceeded.
  • Update granularity: usage counters (lamp/filter) return one-second units but are internally updated at one-minute intervals.

Known Gaps

- "source document is a generic Sharp/NEC projector command reference; model-specific support flags and \"Supplementary Information by Command\" appendix (input-terminal value tables, base-model-type values, eco-mode values, sub-input values) are referenced but not included in the refined excerpt. Firmware compatibility not stated."
- "no unsolicited notification events documented in source."
- "no multi-step sequences described explicitly in source."
- "source does not specify voltage/current/power specs, fault recovery sequences, or full power-on sequencing requirements. Error bitmasks indicate fault detection (cover, fan, temperature, interlock switch open) but explicit safety interlock procedures are not documented."
- "\"Supplementary Information by Command\" appendix (input-terminal value map, base-model-type values, eco-mode values, sub-input values) referenced repeatedly but not present in the refined excerpt."
- "model code (ID2) value for P243W Bk not stated in source."
- "which 030-1 picture-adjust targets / 053 lens-control targets / 097-198 sub-inputs are actually supported on this model not stated."
