Sharp/NEC E224Fl Bk Control Spec

Summary

Control spec derived from the Sharp/NEC Projector Control Command Reference Manual (BDT140013 Revision 7.1). The device exposes a binary hex-framed command protocol over RS-232C serial (D-SUB 9P, PC CONTROL) and over wired/wireless LAN (TCP port 7142). Commands cover power, input switching, picture/volume/aspect/gain adjustment, mute, shutter, lens control and lens memory, status queries, LAN/eco/PIP/edge-blending settings, and base-model/serial-number information requests.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200/38400/19200/9600/4800  # source lists all five; device auto/configurable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: RTS/CTS pins wired (D-SUB 9P) but flow-control mode not explicitly stated in source
addressing:
  port: 7142  # TCP, stated for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF present
  - queryable    # inferred: many status/information request commands present
  - levelable    # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST present

Actions

# Frame (hex): <STX-based> ... <CKS>. CKS = low byte of sum of all preceding bytes.
# ID1 = projector control ID; ID2 = model code (UNRESOLVED for this model).
# Verbatim command payloads below include the checksum byte exactly as written in the source.

Events

# No unsolicited notifications are documented in the source.

Macros

# No multi-step sequences are documented explicitly in the source.

Safety

confirmation_required_for: []
interlocks:
  - "Power On (015): while turning power on, no other command can be accepted."
  - "Power Off (016): while turning power off (including cooling time), no other command can be accepted."
# No additional safety warnings, interlock procedures, or power-on sequencing
# requirements are stated in the refined source beyond the power on/off block above.

Notes

• Frame format: commands/responses are hex-framed. Checksum (CKS) = low-order byte of the sum of all preceding bytes (see worked example in source §2.2). Every command payload above carries its checksum verbatim where the source provides a fixed one; parameterized commands carry a {checksum} computed field.
• IDs: ID1 = projector control ID (configurable); ID2 = model code. ID2 for this model is not stated in the source (UNRESOLVED).
• Response convention: success responses are echoed with the command opcode in the A0h/A1h/A2h/A3h acknowledgement family and carry ERR1/ERR2 on failure (see source §2.4 error-code table).
• Baud rate: five rates supported (115200 / 38400 / 19200 / 9600 / 4800); the device is configurable, so a single canonical baud_rate is not fixed by the source.
• Refresh granularity: lamp/filter usage times are obtainable in 1-second units but updated at 1-minute intervals.

summary: "All 53 spec actions matched literally to source with correct opcode sequences and parameters; transport settings (baud rates, port 7142) confirmed verbatim. (9 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "the source manual is a generic multi-model projector reference; it does not itself name the \"E224Fl Bk\" model. Confirm this manual applies to the E224Fl Bk against the device or vendor."
- "input-terminal value table (DATA01 of 018), aspect value table, base-model-type table, eco-mode value table, and sub-input value table are referenced to an \"Appendix: Supplementary Information by Command\" that is not present in the refined source."
- "ID2 (model code) value for this model is not stated in the source."
- "RTS/CTS pins wired (D-SUB 9P) but flow-control mode not explicitly stated in source"
- "not present in refined source).\""
- "numeric enum values not present in refined source (Appendix missing)."
- "source is a generic projector command reference (BDT140013 Rev 7.1) and does not name the \"E224Fl Bk\" — model applicability unconfirmed."
- "Appendix \"Supplementary Information by Command\" (input terminal, aspect, base-model-type, eco-mode, sub-input value tables) not present in refined source."
- "ID2 model code, exact flow-control mode, and firmware compatibility not stated in source."
