Summary

Sharp/NEC projector (document BDT140013 Rev 7.1) controllable over TCP/IP (wired/wireless LAN) and RS-232C serial. Binary protocol with hex-byte command frames, each terminated by a one-byte checksum. Covers power, input switching, mute, picture/volume/aspect/lens adjustment, shutter, freeze, lens memory, eco mode, edge blending, PIP/PbP, and a broad set of status/information queries.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # supported rates; default UNRESOLVED (not stated)
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex" communication mode
auth:
  type: none  # inferred: no auth procedure in source

Command framing: All commands/responses are hex-byte frames of the form <hdr> <cmd> <ID1> <ID2> <LEN> <DATA…> <CKS> where ID1 = control ID set on projector, ID2 = model code, LEN = byte length of the data part, and CKS = checksum = low-order byte of the sum of all preceding bytes. Response frames begin with 2xh (success), Axh (error, with ERR1/ERR2), or 2xh+data (data responses). Several commands are fully literal (no ID1/ID2/LEN/CKS shown because they are request skeletons); parameterized commands show <DATA…> placeholders.

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: numerous status/information request commands
  - routable     # inferred: INPUT SW CHANGE command present
  - levelable    # inferred: picture/volume/lens adjustment commands present

Notes

  • Binary protocol over both TCP (port 7142) and RS-232C serial. Serial supports baud 4800/9600/19200/38400/115200; default rate not stated in source.
  • Checksum = low-order byte of sum of all preceding bytes in the frame (including header/cmd/ID/LEN/data).
  • ID1 (control ID) and ID2 (model code) are inserted into responses by the projector; commands sent to the projector in this manual's skeleton form omit them but a real implementation must populate them per the projector's configured control ID and the model code.
  • Lamp usage/filter usage times update at one-minute intervals though reported in one-second units.
  • Lamp remaining life (%) returns negative if replacement deadline exceeded.
  • PIP "Lamp 2" (DATA01=01h) effective only on two-lamp projector models.

Known Gaps

- "default serial baud rate not stated (multiple rates supported)"
- "ID2 model code value for PN-HS431 not stated in source"
- "firmware version compatibility not stated"
- "full input-terminal code table is in an Appendix (\"Supplementary Information by Command\") not included in this refined source excerpt — aspect/input/audio/eco-mode enum values partially incomplete"
- "wireless LAN details deferred to separate operation manual"
