Summary

Control spec for the Sharp/NEC M551 Pt projector (BDT140013 Rev 7.1 Command Reference). Covers RS-232C serial control (PC CONTROL D-SUB 9P, cross cable) and wired/wireless LAN control (TCP port 7142). Binary framed protocol with hex opcodes, ID1/ID2, length, data, and a trailing additive low-byte checksum.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # supported set; default UNRESOLVED
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow_control not explicitly stated in source (full-duplex communication mode stated)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable    # inferred: many status request commands present
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 053 LENS CONTROL present
  - routable     # inferred: 018 INPUT SW CHANGE present

Safety

confirmation_required_for:
  - power_off  # projector enters cooling period; no other command accepted during cool-down
  - shutter_close  # optical output blocked
interlocks:
  - "During POWER ON ramp-up, no other command can be accepted (source §3.2)."
  - "During POWER OFF including cooling time, no other command can be accepted (source §3.3)."
  - "Commands issued while power is off return ERR1=02h ERR2=0Dh ('The command cannot be accepted because the power is off')."
  - "Forced onscreen mute (ERR1=02h ERR2=04h) can block command execution."
  - "Interlock switch open or portrait cover side up surfaces in ERROR STATUS REQUEST DATA09."
# UNRESOLVED: source contains no explicit power-on sequencing procedure beyond
# the per-command interlock notes above; no voltage/current/power values stated.

Notes

  • Protocol framing: every command/response is a hex byte stream. Format 20h 88h <ID1> <ID2> 0Ch <DATA01> - <DATA12> <CKS>. <ID1> = control ID set on projector; <ID2> = model code (varies by model); <CKS> = additive checksum, low-order byte of sum of all preceding bytes. Example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.
  • Response prefix groups: 2xh = ACK, Axh = NAK (with ERR1/ERR2). First command byte 00h/01h/02h/03h maps to response ACK prefix 20h/21h/22h/23h and NAK prefix A0h/A1h/A2h/A3h.
  • Timing: lamp/filter usage time updated at one-minute intervals even though values are in one-second units.
  • Multi-baud: serial supports 4800/9600/19200/38400/115200 bps — match the projector's configured rate; default rate UNRESOLVED.
  • Two-lamp models: LAMP INFORMATION REQUEST 3 DATA01=01h (Lamp 2) only valid on two-lamp models.
  • Appendix tables referenced but absent from this source extract: input terminal codes, aspect values, eco mode values, base model type values, sub input setting values. All marked UNRESOLVED inline.

Spec done. 53 actions (one per source command row). Tier-1 direct values only; Tier-2 inferences flagged; appendix tables + default baud + ID2 model code marked UNRESOLVED.
