Summary

Sharp/NEC projector controlled via binary hex command protocol over RS-232C serial or TCP/IP (wired/wireless LAN). Commands are framed with header bytes, control ID, model code, data length, payload, and a low-byte checksum. Covers power, input switching, mute, picture/volume/aspect adjust, lens control and memory, status queries, eco mode, PIP/PbP, edge blending, and identity requests.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # TCP port stated for LAN command send/receive
serial:
  baud_rate: 115200  # source: 115200/38400/19200/9600/4800 bps selectable
  # full selectable set: [4800, 9600, 19200, 38400, 115200]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not stated in source (RTS/CTS pins wired but flow-control mode not specified)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many REQUEST commands returning state
  - routable     # inferred: INPUT SW CHANGE command present
  - levelable    # inferred: PICTURE/VOLUME/OTHER ADJUST commands present

Actions

# Command frame: <hdr> <ID1> <ID2> <LEN> <DATA...> <CKS>
# CKS = low byte of sum of all preceding bytes. ID1=control ID, ID2=model code
# (device-specific). Templates below show literal command bytes as written in source;
# <ID1>/<ID2>/<CKS> are runtime-computed.

Events

# No unsolicited notifications documented. Device responds only to commands.

Macros

# No multi-step sequences explicitly documented in source.

Safety

confirmation_required_for: []
interlocks: []
# Notes: 015 POWER ON and 016 POWER OFF reject all other commands during the power
# transition (incl. cooling). No explicit safety interlock procedures documented.
# <!-- UNRESOLVED: no explicit safety warnings, interlock sequences, or power-on
# sequencing requirements stated in this excerpt. -->

Notes

  • Command frame: <hdr> <ID1> <ID2> <LEN> <DATA...> <CKS>. Response header high nibble flips 0→2, 2→A, 3→2/3 (success/failure variants). Failure response carries <ERR1> <ERR2> from the error code table (e.g. 02h/0Dh = "command cannot be accepted because the power is off").
  • Checksum: low byte of sum of all preceding bytes (example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h).
  • Lamp/filter usage times update at 1-minute intervals though stored in 1-second units.
  • Lamp remaining life (%) returns negative if past replacement deadline.
  • "01h" Lamp 2 selector only valid on two-lamp models.
  • Signal list number returned is practical value − 1 (add 1 for actual).

Spec done. 52 actions enumerated (all cmd-bearing entries from §3), dual transport w/ stated port 7142 + full serial set, no fabricated volts/amps/baud-defaults. Appendix value tables + ID2 model code left UNRESOLVED (not in excerpt).

matched_actions: 53
action_count: 53
confidence: medium
summary: "All 53 spec actions matched verbatim against source; transport parameters (port 7142, baud 115200, 8N1) confirmed in source documentation. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "exact Ld D091 model family mapping not confirmed in source (doc is generic \"Projector Control Command Reference Manual\" BDT140013 Rev 7.1). Input-terminal value tables and eco-mode value table referenced to \"Appendix: Supplementary Information by Command\" which is not in this refined excerpt."
- "not stated in source (RTS/CTS pins wired but flow-control mode not specified)"
- "no explicit safety warnings, interlock sequences, or power-on"
- "input-terminal value table, eco-mode value table, aspect value table, base-model-type values, and sub-input setting values are referenced to \"Appendix: Supplementary Information by Command\" which is NOT present in this refined excerpt."
- "exact Ld D091 model code (ID2) not stated — varies by model."
- "firmware compatibility range not stated."
- "serial flow_control mode not stated (RTS/CTS pins wired but mode unspecified)."
