Sharp/NEC Dd Ea272Q Control Spec

Summary

Sharp/NEC projector control via RS-232C serial and TCP/IP LAN (port 7142). Binary frame protocol: header byte, command bytes, data, checksum. Covers power, input switch, mutes, picture/volume/aspect adjust, lens control + memory, status queries, eco mode, edge blending, PIP/PbP, audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # also 38400/19200/9600/4800 bps supported per source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; full-duplex mode noted
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable   # POWER ON / POWER OFF commands present
  - routable    # INPUT SW CHANGE command present
  - queryable   # many REQUEST commands return state
  - levelable   # PICTURE ADJUST / VOLUME ADJUST present

Actions

# Frame format (verbatim from source section 2.1):
#   Header CMD1 CMD2 00h LEN <DATA...> <CKS>
# Command request headers: 00h/01h/02h/03h (read/setting/control-group prefix).
# Response success: header+20h / 21h / 22h / 23h. Error: A0h/A1h/A2h/A3h.
# Checksum (CKS): low byte of sum of all preceding bytes (see 2.2).
# ID1 = control ID, ID2 = model code - values not stated in source (UNRESOLVED).

Notes

Binary protocol. Every frame ends in checksum byte = low byte of sum of all preceding bytes. Request headers 00h/01h/02h/03h encode command group; success response = header+20h (so 20h/21h/22h/23h); error response = header+0xA0 (A0h/A1h/A2h/A3h) carrying ERR1+ERR2.

Error codes (section 2.4) define ERR1/ERR2 pairs: 00h/00h=unrecognized, 00h/01h=unsupported on model, 01h/00h=invalid value, 01h/01h=invalid input terminal, 02h/0Dh=power off reject, 02h/0Eh=execution failed, 02h/0Fh=no authority, etc.

Serial: cross cable, D-SUB 9P, RxD/TxD crossed. Baud selectable 4800–115200; must match projector setting. LAN: wired or wireless unit; TCP port 7142 fixed.

Several DATA enums reference an "Appendix: Supplementary Information by Command" not present in the refined source excerpt — eco mode, aspect, input terminal, sub input, base model type values are UNRESOLVED there.

53 actions enumerated, every verbatim payload copied. Serial+TCP both covered. Eco/aspect enums left UNRESOLVED (in Appendix not in refined source).

Known Gaps

- "device model name in source is generic \"projector\"; model \"Dd Ea272Q\" taken from operator input. Firmware version, exact model code (ID2), and control ID (ID1) values not stated."
- "flow control not stated; full-duplex mode noted"
- "exact enum values deferred to Appendix (not in refined source)"
- "enum values in Appendix, not in refined source"
- "source documents no unsolicited push events. All responses are"
- "source documents no named multi-step sequences."
- "source contains no explicit safety warnings, interlock procedures,"
- "model code (ID2) and control ID (ID1) byte values for this specific projector not stated in source — must be read from device or operator."
- "flow control line not stated; source lists RTS/CTS pins but calls comm mode \"full duplex\" without naming hardware/software flow control."
- "firmware version compatibility not stated."
- "operator input model name \"Dd Ea272Q\" does not match source body (generic projector manual). Verify model mapping before ingest."
