Summary

Sharp/NEC projector control spec covering RS-232C serial and TCP/IP (wired/wireless LAN) control. Uses a binary framed command protocol with checksummed hex payloads (BDT140013 Rev 7.1). Covers power, input switching, mute, picture/volume/lens adjustment, status queries, and lens memory control.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: null  # UNRESOLVED: default baud not stated; source lists supported set 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated (RTS/CTS pins present on connector)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable   # inferred: POWER ON / POWER OFF commands present
  - routable    # inferred: INPUT SW CHANGE command present
  - queryable   # inferred: many status/information request commands present
  - levelable   # inferred: PICTURE ADJUST / VOLUME ADJUST commands present

Actions

# Protocol framing: each command is a hex byte sequence. Framing bytes
# (first byte = message-type/op marker), ID1 (control ID), ID2 (model code),
# and CKS (checksum = low byte of sum of all preceding bytes) are part of the
# wire format. ID1/ID2 are runtime-substituted; CKS is computed. Payloads below
# are copied verbatim from the source.
# Model code ID2: UNRESOLVED (varies by model; not stated for Me651).

Notes

  • Framing: Commands use a fixed-format hex frame. The leading byte encodes message class (00h/01h/02h/03h are requests; 20h/21h/22h/23h are success responses; A0h/A1h/A2h/A3h are error responses). <ID1> = projector control ID; <ID2> = model code; <CKS> = checksum (low byte of the sum of all preceding bytes).
  • Checksum example (from source): 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.
  • Power behavior: POWER ON/OFF block all other commands during execution (incl. cooling). Implementers should poll 078-2 RUNNING STATUS REQUEST to determine readiness.
  • Default ID1/ID2: Not stated in this excerpt; typically set per-projector.
  • Appendix references: Several commands (018 INPUT SW CHANGE, 030-12 ASPECT ADJUST, 097-8 ECO MODE REQUEST, 098-8 ECO MODE SET, 098-198/097-198 sub-input values, 319-10 input terminal) defer value tables to an "Appendix: Supplementary Information by Command" that is not present in this refined source. Those enum tables are therefore UNRESOLVED.

Spec output above. 53 actions, all hex payloads verbatim. Source is generic NEC BDT140013 manual — does not name Me651 explicitly; flagged UNRESOLVED. Default baud/flow control/model-code/appendix enum tables all marked unresolved per policy.

Known Gaps

- "source is a generic \"Projector Control Command Reference Manual\" (BDT140013) and does not state the model name Me651; model mapping assumed by operator. Model code (ID2) value for this model not stated in source."
- "default baud not stated; source lists supported set 115200/38400/19200/9600/4800 bps"
- "flow control not stated (RTS/CTS pins present on connector)"
- "source does not document any unsolicited (push) notifications."
- "source does not describe any multi-step command sequences."
- "no formal power-on sequencing procedure or safety interlock procedure is documented."
- "default baud rate not stated (5 options listed)."
- "serial flow control not stated (RTS/CTS pins wired on D-SUB 9P)."
- "model code (ID2) value for Me651 not stated in source."
- "default control ID (ID1) not stated."
- "firmware version compatibility not stated."
- "input terminal / aspect / eco-mode / sub-input enum value tables referenced but not included in this source excerpt."
- "source document is a generic NEC projector command reference (BDT140013 Rev 7.1); it does not name Me651 explicitly — model association provided by operator."
