Sharp/NEC Xp M421W W Control Spec

Summary

Sharp/NEC Xp M421W W projector control spec. Covers RS-232C serial and wired/wireless LAN (TCP) control per Projector Control Command Reference Manual (BDT140013 Rev 7.1). Binary frame protocol with hex opcodes, checksum bytes, and ID/model bytes.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # supported: 4800/9600/19200/38400/115200; default not stated in source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex" communication mode; specific flow control not named
addressing:
  port: 7142  # TCP port stated for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON / POWER OFF commands
  - queryable       # inferred: many REQUEST commands return state
  - levelable       # inferred: PICTURE ADJUST, VOLUME ADJUST

Variables

# Settable parameters that are not discrete actions. The source documents
# parameter-set commands individually; those appear as Actions above.
# UNRESOLVED: no separate continuous-variable surface beyond Actions.

Events

# Source describes no unsolicited notifications. All responses are solicited
# replies to commands.
# UNRESOLVED: none expected.

Macros

# Source documents no multi-step command sequences.
# UNRESOLVED: none expected.

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 (incl. cooling time)."
  - "Cover/interlock error bits reported in ERROR STATUS REQUEST (DATA09 Bit1: interlock switch open)."
# UNRESOLVED: no explicit confirmation-required list stated in source.

Notes

• Binary frame protocol. Format: {hdr} {cmd} <ID1> <ID2> {LEN} <DATA...> <CKS>. Header byte distinguishes direction/type (00h/01h/02h/03h = commands by category; 20h/21h/22h/23h = success responses; A0h/A1h/A2h/A3h = error responses).
• ID1 = control ID set on projector; ID2 = model code (varies by model). Both must be supplied by the controller — values not in source.
• Checksum (CKS): sum of all preceding bytes, low-order one byte. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
• Serial cable: cross cable, D-SUB 9P, pin 2 RxD / 3 TxD / 5 GND / 7 RTS / 8 CTS.
• LAN: wired RJ-45 (10/100 auto) or optional wireless LAN unit. TCP port 7142.
• Baud rates 4800/9600/19200/38400/115200 supported; default not stated in source — 9600 used as placeholder above, treat as UNRESOLVED for default.
• Manual is shared across many Sharp/NEC projector models. Per-command model availability is governed by an "Appendix: Supplementary Information by Command" not present in this source — value tables for input terminals, eco mode, aspect, sub-inputs, and base model types are UNRESOLVED.
• Lamp/filter usage times returned in seconds, updated at 1-minute intervals.

Known Gaps

- "manual is generic across many Sharp/NEC projectors; model-specific command availability (\"Supplementary Information by Command\" appendix) not present in source. Firmware version compatibility not stated. Input terminal value table, eco-mode value table, aspect value table, sub-input value tables referenced but not included."
- "no separate continuous-variable surface beyond Actions."
- "none expected."
- "no explicit confirmation-required list stated in source."
- "ID1 (control ID) and ID2 (model code) values for this projector not stated in source."
- "default baud rate not stated (9600 placeholder above)."
- "model-specific command availability table (Appendix) not in source."
- "input terminal value table, eco mode value table, aspect value table, sub-input value table, base model type table not in source."
- "firmware version compatibility not stated."
- "voltage/current/power specs not in this manual."
