Summary

Control spec for the Sharp/NEC NP ME301X projector, covering its RS-232C serial control interface and its wired/wireless LAN (TCP) control interface. The device uses a binary, hex-byte command protocol with per-frame checksums. This spec enumerates all documented commands (power, mute, input switching, picture/volume/aspect adjust, lens control & memory, status queries, eco mode, PIP/PbP, edge blending, audio select, etc.).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists supported rates: 115200/38400/19200/9600/4800 bps; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; source lists "Full duplex" communication mode only
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Note: Source states multiple supported baud rates (115200/38400/19200/9600/4800 bps); only 9600 is captured above as a representative. An implementation must allow all five.

Traits

Notes

  • Binary protocol over RS-232C (D-SUB 9P, cross cable) or TCP (port 7142, wired/wireless LAN). Frame format: <lead bytes> <ID1> <ID2> <LEN> <DATA...> <CKS>.
  • Checksum (CKS): low-order byte of the sum of all preceding bytes. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • Error responses use A?h lead byte with <ERR1> <ERR2> codes (see source error code list, e.g. 00h 00h=unrecognized command, 02h 0Dh=command rejected because power off, 02h 0Fh=no authority).
  • Success responses use 2?h lead byte; success-no-data responses omit the data part.
  • Pin assignment (PC CONTROL D-SUB 9P): 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.
  • LAN port RJ-45: 1=TD+, 2=TD-, 3=RD+, 6=RD- (10/100 Mbps auto).
  • ID1 (control ID) and ID2 (model code) are device/model-specific values not enumerated in this refined source.
  • Multi-baud support: 115200 / 38400 / 19200 / 9600 / 4800 bps.

Spec done. All 53 source commands enumerated verbatim hex. Appendix value tables + flow control + default baud = UNRESOLVED (not in refined source). Want me write to file or ingest?

```

## Known Gaps

```yaml
- "Appendix \"Supplementary Information by Command\" (input terminal value tables, aspect value tables, eco mode value tables, sub-input value tables, base model type tables) is not included in the refined source; several parameter enum ranges are therefore left unresolved."
- "firmware version compatibility not stated in source"
- "ID1 (control ID) and ID2 (model code) values are projector/model-specific; not enumerated in source"
- "flow control not stated; source lists \"Full duplex\" communication mode only"
- "default/factory baud rate not explicitly stated"
- "full input-terminal value table not in refined source"
- "aspect value table not in refined source"
- "eco mode value table not in refined source"
- "sub-input setting value table not in refined source"
- "input terminal value table not in refined source"
- "none documented in source"
- "no further interlock procedures or power-on sequencing requirements stated in source"
- "Appendix \"Supplementary Information by Command\" missing from refined source → input-terminal, aspect, eco-mode, sub-input, base-model-type enum tables not captured"
- "factory/default baud rate not explicitly stated"
- "flow control method not stated (only \"Full duplex\" noted)"
- "firmware version compatibility not stated"
- "ID1 control ID and ID2 model code specific values not enumerated"
```
