Summary

Sharp/NEC NP M430WL projector control spec covering the binary frame protocol documented in the Projector Control Command Reference (BDT140013 Rev 7.1). The device supports RS-232C serial control and wired/wireless LAN control using TCP port 7142. Commands are variable-length hex frames terminated with a checksum byte; responses echo with a success (2xh) or error (Axh) lead byte.

Transport

# Source documents BOTH RS-232C serial and LAN (TCP). Both populated.
# User known_protocol: RS-232C; source explicitly adds TCP port 7142.
protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # all stated as supported; host selects one
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: not listed in communication conditions table; RTS/CTS pins present in PC CONTROL pinout (pins 7/8 cross-wired), full-duplex mode stated
addressing:
  port: 7142  # TCP port for LAN command send/receive
auth:
  type: none  # inferred: no login/auth procedure described in source

Traits

# Inferred from documented command set:
- powerable  # inferred: POWER ON / POWER OFF commands present
- queryable  # inferred: extensive status/information request commands present
- levelable  # inferred: PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST gain commands present
- routable   # inferred: INPUT SW CHANGE input switching command present

Actions

# All frames are host→projector command bytes verbatim from source. Last byte of a
# fixed frame is the precomputed checksum (CKS). For parameterized frames the variable
# DATA byte(s) are shown as placeholders and CKS must be recomputed per the checksum
# rule (sum all preceding bytes, take low-order 8 bits). ID1=control ID set on
# projector; ID2=model code (both appear only in response frames).

Events

# No unsolicited notification protocol described in source. All responses are
# solicited (returned after a command). 
# UNRESOLVED: no async/event mechanism stated in source.

Macros

# UNRESOLVED: no multi-step command sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    note: "While POWER ON is executing, no other command can be accepted."
  - command: power_off
    note: "While POWER OFF is executing (including cooling time), no other command can be accepted."
  - command: any
    note: "Error 02h/0Dh returned when a command cannot be accepted because the power is off."
# UNRESOLVED: no explicit power-on sequencing or hardware interlock voltages stated.

Notes

  • Checksum rule: sum all bytes preceding CKS, take the low-order 8 bits. Example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.
  • Frame lead bytes indicate command group and direction: 0xh/1xh/2xh/3xh are request/success-response groups; Axh lead bytes (A0h–A3h) denote error responses carrying ERR1/ERR2.
  • ID1 = control ID configured on the projector; ID2 = model code (varies by model). Both appear in response frames only, not in the host-sent command frames.
  • Usage-time fields (lamp/filter) are obtainable in one-second units but updated at one-minute intervals.
  • For LAMP INFORMATION REQUEST 3, if the lamp replacement deadline is exceeded, remaining life (%) is returned as a negative value.
  • Serial cable is a cross cable wired to the PC CONTROL D-SUB 9P port (RxD/TxD/GND/RTS/CTS cross-connected).
  • Input terminal DATA01 value map, aspect value map, eco mode value map, and base model type value map are referenced to an appendix ("Supplementary Information by Command") that is not present in this refined source.

Spec done. 53 actions, all verbatim hex. Both serial+TCP populated (port 7142 stated). Flow_control + appendix enum maps marked UNRESOLVED. Drafts.jsonl path next if want ingest.

## Known Gaps

```yaml
- "firmware version compatibility not stated in source"
- "exact NP M430WL model code (ID2) value not stated in this command reference"
- "input terminal DATA01 value map referenced to an appendix not present in refined source"
- "not listed in communication conditions table; RTS/CTS pins present in PC CONTROL pinout (pins 7/8 cross-wired), full-duplex mode stated"
- "no async/event mechanism stated in source."
- "no multi-step command sequences explicitly described in source."
- "no explicit power-on sequencing or hardware interlock voltages stated."
- "exact model code (ID2) for NP M430WL not stated in this command reference"
- "serial flow_control setting not listed in communication conditions table (RTS/CTS pins present in pinout)"
- "input terminal / aspect / eco mode / base model type enum maps referenced to absent appendix"
