Sharp/NEC NP-02HD Control Spec

Summary

Sharp/NEC NP-02HD projector. Hex frame protocol over RS-232C serial (D-SUB 9P cross cable) and TCP/IP (wired/wireless LAN, port 7142). 53 commands covering power, input switch, mutes, picture/volume/aspect/gain adjust, shutter, lens control + memory, status/information queries, remote key emulation, eco mode, PIP/PbP, edge blending, audio select. BDT140013 manual rev 7.1.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source: selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source says full-duplex; specific flow control not stated
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, audio select, PIP sub-input
  - queryable       # inferred: many 037/078/097/305 request commands
  - levelable       # inferred: 030-1 PICTURE, 030-2 VOLUME, 030-15 OTHER ADJUST
  - shutterable     # inferred: 051/052 SHUTTER CLOSE/OPEN (lens shutter)

Actions

# Each hex frame is command verbatim from source. Frame format:
#   <HDR> <CMD> <ID1 ID2> <LEN> <DATA...> <CKS>
# HDR byte reflects operation class: 00h/01h/02h/03h = request/command,
# 20h/21h/22h/23h = ack response, A0h/A1h/A2h/A3h = error response.
# CKS = low byte of sum of all preceding bytes (see §2.2 example).
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# For command frames, the leading literal bytes shown below are the
# verbatim payload - ID1/ID2/CKS are computed at send time per §2.2.

Feedbacks

# Devices respond with structured hex frames (no unsolicited feedback).
# Response HDR: 20h/21h/22h/23h = success ack; A0h/A1h/A2h/A3h = error.
# Error frame carries ERR1/ERR2 code pair - see §2.4 list (22 codes incl.
# 00h 00h "unrecognized", 02h 0Dh "command cannot be accepted because
# power is off", 02h 0Fh "no authority", etc.).

Events

# Source documents no unsolicited events. All output is response to command.

Macros

# UNRESOLVED: source describes no multi-step command sequences.

Safety

interlocks:
  - "Power on sequence: no other command accepted during power-on (015)."
  - "Power off sequence: no other command accepted during cool-down (016)."
  - "DATA09 bit1 (interlock switch open) surfaced via 009 ERROR STATUS REQUEST - source notes bit but no recovery procedure."
# UNRESOLVED: source mentions cover/temperature/fan/lamp error bits but no
# interlock recovery sequence or power-on ordering requirement beyond the
# "no other command during power transitions" notes above.

Notes

• Multi-model command reference (BDT140013 rev 7.1). NP-02HD is one of many supported projectors; not all commands may apply to NP-02HD specifically.
• Frame structure: header byte (00h/01h/02h/03h = command, 2Xh = ack, AXh = error) + command byte + ID1 (control ID set on projector) + ID2 (model code, varies) + LEN + DATA + CKS.
• Checksum = low byte of sum of all preceding bytes. Source example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
• Serial cable is cross (null-modem). Pin 2/3 cross, pin 7/8 cross, pin 5 GND straight.
• LAN port 7142 used for both send and receive.
• Source excerpt omits Appendix "Supplementary Information by Command" — input terminal codes, eco mode values, sub-input values, base model type values, aspect values are referenced but not enumerated.

Known Gaps

- "source covers command set for family of projectors (multi-model reference); exact NP-02HD-specific subset not enumerated. Appendix \"Supplementary Information by Command\" not present in refined excerpt — input terminal values, base model type values, eco mode values, sub input values referenced but not listed here."
- "enum values live in Appendix not present in refined excerpt"
- "source describes no multi-step command sequences."
- "source mentions cover/temperature/fan/lamp error bits but no"
- "NP-02HD-specific subset of commands not identified."
- "Appendix \"Supplementary Information by Command\" tables not in refined excerpt — input terminal / eco mode / sub input / aspect / base model type enums missing."
- "firmware version compatibility not stated."
- "full 053 LENS CONTROL DATA01 target enumeration not in source (only 06h=Periphery Focus listed)."
- "full 030-15 OTHER ADJUST DATA01/02 target matrix not in source (only 96h/FFh=LAMP/LIGHT ADJUST listed)."
