Sharp/NEC NP-P554U Control Spec

Summary

Sharp/NEC NP-P554U projector. Binary control protocol over RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP port 7142). Hex command frames with checksum. Covers power, input switching, mutes, lens/shutter, picture/volume adjust, status queries, and LAN/PIP/eco settings per the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source: 115200/38400/19200/9600/4800 bps configurable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow_control not stated in source
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: extensive status query commands present
  - levelable    # inferred: PICTURE ADJUST / VOLUME ADJUST present

Actions

# All command frames use hex bytes verbatim from source. ID1 = control ID set on
# projector (00h when unspecified), ID2 = model code (varies by model, 00h placeholder),
# CKS = checksum computed as low byte of sum of all preceding bytes.
# Command frame format: <DATA?>_<CKS> where CKS = low-order byte of sum of all preceding bytes.

Variables

# Picture adjust values (brightness/contrast/color/hue/sharpness) and volume are

# No unsolicited notifications documented in source. All responses are solicited

Notes

• Command frame format: hex bytes. Host fills ID1 (control ID set on projector, 00h if unset) and ID2 (model code, varies by model). CKS = low-order byte of sum of all preceding bytes.
• Baud rate configurable: 115200 / 38400 / 19200 / 9600 / 4800 bps. Spec lists 115200 as the default-shown value; matching device setting required.
• Serial cable: cross cable, D-SUB 9P, PC CONTROL port. Pinout: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS.
• LAN: wired RJ-45 (10/100 Mbps auto) or wireless LAN unit. TCP port 7142 for command send/receive.
• Response success for no-data commands: 2?h <ID1> <ID2> 00h <CKS>. For data commands, LEN and DATA appended.
• Usage times update at one-minute intervals despite one-second resolution.
• Lamp remaining life (%) returns negative value if replacement deadline exceeded.

Spec output complete. 53 commands enumerated (sections 3.1–3.53), all hex payloads verbatim. Gaps marked UNRESOLVED: model code (ID2), flow_control, appendix value tables, firmware range.

## Known Gaps

```yaml
- "firmware version compatibility not stated in source"
- "model code (ID2) value for NP-P554U not stated in source"
- "flow_control not stated in source"
- "wireless LAN comm conditions not in this document"
- "Appendix \"Supplementary Information by Command\" (input terminal values, aspect values, base model type values, sub input values, eco mode values) not included in source text"
- "full response payload decoding for queries not exhaustively enumerated."
- "no separate variable model defined; settable state is action-driven per source."
- "no async/event mechanism described in source."
- "none documented."
- "no dedicated safety/interlock section in source."
- "ID2 model code value for NP-P554U not in source"
- "flow_control setting not stated"
- "Appendix \"Supplementary Information by Command\" (input terminal / aspect / base model type / sub input / eco mode value tables) not present in refined source"
- "firmware version compatibility range not stated"
- "wireless LAN comm conditions reference external operation manual"
- "model code (ID2), flow_control, appendix value tables, firmware range."
