Sharp/NEC XP X171Q W Control Spec

Summary

Sharp/NEC XP X171Q W projector. Binary control protocol over RS-232C serial (D-SUB 9P, PC CONTROL port) and wired/wireless LAN. Manual BDT140013 Rev 7.1 lists 54 command opcodes covering power, mute, input switch, picture/volume/aspect adjust, lens control + memory, information/status queries, eco mode, LAN name, PIP/PbP, edge blending, audio select. All commands framed hex with ID1/ID2/LEN/CHECKSUM.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists all 5; default UNRESOLVED
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source says "Full duplex" communication mode but no flow_control pin usage for control
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable     # inferred: 015 POWER ON / 016 POWER OFF
  - routable      # inferred: 018 INPUT SW CHANGE
  - queryable     # inferred: many REQUEST commands
  - levelable     # inferred: 030-2 VOLUME ADJUST, 030-1 PICTURE ADJUST

Actions

# Checksum rule (from source §2.2): CKS = low-order byte of sum of all
# preceding bytes. ID1 = control ID, ID2 = model code (both projector-set).
# Frame markers: 20h/21h/22h/23h = command/request prefix variants by class;
# A0h/A1h/A2h/A3h = response prefix variants. "h" = hex notation verbatim.

Safety

confirmation_required_for: []
interlocks:
  - command: cmd_015_power_on
    note: "No other command accepted while power-on in progress (source §3.2)."
  - command: cmd_016_power_off
    note: "No other command accepted during power-off incl. cooling time (source §3.3)."
  - command: cmd_053_lens_control

# UNRESOLVED: no other explicit safety warnings, power-on sequencing, or

Notes

• Binary protocol. All frames hex notation with h suffix verbatim from source.
• Frame structure: [prefix] [opcode] [ID1] [ID2] [LEN] [DATA...] [CKS]. Command prefixes: 00h/01h/02h/03h = command (class bit pattern), 20h/21h/22h/23h = ack response, A0h/A1h/A2h/A3h = error response.
• Checksum: low-order byte of sum of all preceding bytes (incl. prefix, opcode, ID1, ID2, LEN, DATA). See worked example in source §2.2.
• ID1 = control ID set on projector. ID2 = model code (varies by model).
• Serial cable = cross cable to PC CONTROL (D-SUB 9P). Pinout in source §1.1.
• LAN: TCP port 7142. Wired RJ-45 10/100 auto. Wireless via optional WLAN unit.
• Power-off enters cooling time during which all commands rejected.
• Lamp/filter usage updated 1-minute intervals though queried in 1-second units.

54 actions emitted — all rows from source §2 command list. Verbatim hex payloads preserved. Gaps marked.

## Known Gaps

```yaml
- "firmware version not stated. Input terminal value list, eco mode value list, aspect value list, base model type value list, sub-input value list all live in \"Appendix: Supplementary Information by Command\" — appendix NOT in refined source, so enum values missing. Default baud rate not specified (4 options given)."
- "source says \"Full duplex\" communication mode but no flow_control pin usage for control"
- "response strings for many queries (information strings, PIP/PbP values) partially enumerated in source; full enum tables in appendix"
- "source describes only request/response model. No unsolicited"
- "no multi-step sequences documented in source."
- "no other explicit safety warnings, power-on sequencing, or"
