Sharp/NEC E244Fl Bk Control Spec

Summary

Control spec for the Sharp/NEC E244Fl Bk derived from the vendor "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). The source documents both an RS-232C serial interface and a wired/wireless LAN interface using a binary, checksum-framed command protocol. All commands are expressed as hexadecimal byte sequences framed with header bytes, ID fields, a data length, variable data, and a trailing checksum byte.

Transport

# Source documents BOTH serial (RS-232C) and LAN (TCP) interfaces.
protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # configurable: 115200/38400/19200/9600/4800 bps; default not stated in source
  data_bits: 8
  parity: none
  stop_bits: 1
  # flow_control: UNRESOLVED - source communication table lists "Full duplex" only.
  # RTS/CTS pins (7/8) are cross-wired in the D-SUB 9P pin table, but no explicit
  # flow-control setting is stated.
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

# - powerable    # inferred: 015 POWER ON / 016 POWER OFF present
# - queryable    # inferred: numerous ?/REQUEST commands return state
# - levelable    # inferred: 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST present
# - routable     # inferred: 018 INPUT SW CHANGE present

Actions

# All 53 source-documented command rows enumerated. Each named opcode = one action.
# Frame: header + ID1 + ID2 + LEN + DATA?? + CKS. CKS = low byte of sum of all
# preceding bytes (per source section 2.2). ID1 = control ID set on projector;
# ID2 = model code (model-dependent) - both UNRESOLVED per-device values.

Macros

# No multi-step sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks: []
# Notes from source (not safety interlocks per se, but behavioral constraints):
# - POWER ON: no other command accepted while power-on in progress.
# - POWER OFF: no other command accepted during power-off incl. cooling time.
# - LENS CONTROL: continuous drive (7Fh/81h) must be stopped by sending 00h.
# UNRESOLVED: no explicit safety/interlock procedures (e.g. lamp door, power
# sequencing) stated in the extracted source text.

Notes

• Protocol framing: every command/response is a hex byte stream. Header nibble encodes direction+type: 0xh/2xh/3xh request prefixes, 2xh success-response, Axh error-response (second byte = command echo). ID1 = projector control ID, ID2 = model code — both are per-device values not stated in this manual.
• Checksum (CKS): low-order byte of the sum of all preceding bytes. Worked example in source: 20h 81h 01h 60h 01h 00h → 103h → CKS = 03h.
• Baud rate is configurable across {115200, 38400, 19200, 9600, 4800}; no default stated.
• Serial cable is a cross (null-modem) cable on D-SUB 9P; LAN uses RJ-45 (10/100 auto-sensing).
• Several commands reference an "Appendix: Supplementary Information by Command" for enum values (input terminals, aspect, eco mode, base model types, selection signal types, sub-input). That appendix was not present in the extracted source text, so those enum sets are marked UNRESOLVED.

Spec done. 53 actions = all source command rows. Key gaps flagged UNRESOLVED: device/source mismatch (monitor name vs projector manual), missing Appendix enums, flow_control, ID1/ID2.

Want next: ingest via admin path (drafts.jsonl + scraper ingest) or fix device/source mismatch first?

## Known Gaps

```yaml
- "The supplied device name (\"E244Fl Bk\") corresponds to a Sharp/NEC desktop monitor model, but the source document is a *projector* command reference (describes lamp, lens, shutter, edge blending). Confirm that this projector manual is the correct control source for this entity."
- "Appendix \"Supplementary Information by Command\" referenced throughout the source (input terminal values, aspect values, eco mode values, base model types, selection signal types) was not included in the extracted text — several enum value sets cannot be enumerated."
- "appendix not in extracted text.\""
- "enum in source Appendix, not in extracted text\""
- "only 06h shown in extracted text.\""
- "in source Appendix.\""
- "enum in source Appendix.\""
- "enum in source Appendix, not in extracted text"
- "bounds device-specific; query returns upper/lower/current"
- "bounds returned by gain_parameter_request_3 (DATA01=05h)"
- "no push/event mechanism stated in source."
- "none documented."
- "no explicit safety/interlock procedures (e.g. lamp door, power"
- "device-name / source mismatch — \"E244Fl Bk\" is a Sharp/NEC desktop monitor model name, but the source is a *projector* command reference (lamp, lens, shutter, edge-blending commands). Verify this is the intended control doc for this entity."
- "ID1 (control ID) and ID2 (model code) per-device values not stated."
- "firmware version compatibility not stated."
- "source Appendix enum tables (input terminal, aspect, eco mode, base model type, sub-input, selection signal type) not in extracted text."
- "serial flow_control not explicitly stated (only \"Full duplex\"; RTS/CTS cross-wired)."
- "adjustment value bounds are device-specific; only obtainable at runtime via gain_parameter_request_3."
- "device/source mismatch (monitor name vs projector manual), missing Appendix enums, flow_control, ID1/ID2."
