Summary

Sharp/NEC NP-PX2201UL projector control spec covering both RS-232C serial and wired/wireless LAN (TCP) control interfaces. Uses a binary hex frame protocol with per-command checksums (CKS = low-order byte of sum of all preceding bytes). Source documents 53 distinct commands spanning power, input switching, mute, picture/volume adjustment, lens control, lens memory, status queries, and network/device information requests.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists supported values: 115200/38400/19200/9600/4800
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex" communication mode; flow_control not explicitly named
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON / POWER OFF commands
  - routable     # inferred from INPUT SW CHANGE command
  - queryable    # inferred from numerous request/query commands
  - levelable    # inferred from PICTURE ADJUST / VOLUME ADJUST commands

Variables

# Settable parameters are exposed as parameterized Actions above (volume, picture
# adjust, aspect, eco mode, lens position, edge blending, PIP/PbP, projector name).

Events

# Source documents no unsolicited notifications; all responses are solicited
# replies to commands.

Macros

# Source documents no multi-step sequences.

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON: no other command accepted while power-on in progress."
  - "POWER OFF: no other command accepted during power-off including cooling time."
# UNRESOLVED: source contains no explicit safety warnings or power-on sequencing
# requirements beyond the command-acceptance interlocks noted above.

Notes

  • Command frame format: XXh YYh <ID1> <ID2> LEN <DATA...> <CKS>. ID1 = control ID set on projector; ID2 = model code (varies by model). CKS = low-order byte of sum of all preceding bytes (see §2.2 checksum example).
  • Serial cable: cross cable, D-SUB 9P on PC CONTROL port. Pin assignment documented in §1.1.
  • LAN: RJ-45, 10/100 Mbps auto-switchable, IEEE 802.3 / 802.3u. Wireless LAN via separate wireless LAN unit (see operation manual).
  • Usage time fields (lamp, filter) reported in one-second units but updated at one-minute intervals.
  • Lamp remaining life (%) returned as negative value if replacement deadline exceeded.
  • Many DATA01 selector values (input terminal, aspect, eco mode, sub input, base model type) are defined in an Appendix "Supplementary Information by Command" that is not present in the refined source excerpt.

Spec done. 53 actions enumerated — every command row from §2 covered, verbatim hex payloads preserved, parameterized commands show variable parts. Appendix values marked UNRESOLVED (referenced but not in refined source).
