Summary

Sharp/NEC NP ME401W projector control spec covering the PC CONTROL command protocol (document BDT140013 Rev 7.1). The device accepts control over RS-232C (PC CONTROL D-SUB 9P, cross cable) and over a wired/wireless LAN using TCP port 7142. Commands are framed binary messages with a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists selectable rates 115200/38400/19200/9600/4800; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated (RTS/CTS pins present on D-SUB but no flow-control setting described)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred from POWER ON / POWER OFF commands
  - queryable      # inferred from numerous *REQUEST query commands
  - levelable      # inferred from PICTURE ADJUST / VOLUME ADJUST / LENS CONTROL commands
  - routable       # inferred from INPUT SW CHANGE / AUDIO SELECT SET commands

Actions

# All payloads are hex bytes exactly as written in the source.
# Checksum byte (CKS) is the low-order 8 bits of the sum of all preceding bytes.
# Frame parameters ID1 (control ID) and ID2 (model code) are device-assigned.

  # UNRESOLVED: numeric min/max/default bounds are device-reported at runtime; not stated statically in source.

Events

# Device does not document unsolicited notifications. All output is in response to a command.
# UNRESOLVED: populate from source if a separate events section exists in the full manual.

Macros

# No multi-step sequences described explicitly in source.
# UNRESOLVED: populate from source if applicable.

Safety

confirmation_required_for:
  - power_off  # source: "While this command is turning off the power (including the cooling time), no other command can be accepted."
  - power_on   # source: "While this command is turning on the power, no other command can be accepted."
interlocks:
  - "Power on/off commands lock out all other commands for the duration of the transition (including cooling time)."
  - "Error status DATA09 Bit1: interlock switch open is a fault condition."
  - "Error status DATA04 Bit7: lens not installed properly is a fault condition."
# UNRESOLVED: source does not describe a separate power-on sequencing procedure or
# hardware interlock wiring; only the command-lockout behaviour during power transitions
# and the error-status bit flags are stated.

Notes

  • Command framing: every message is 20h|02h|03h|01h <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS> (request bytes vary by command class — see each command's literal payload). Checksum = low-order 8 bits of the sum of all preceding bytes (worked example in source §2.2: 20h 81h 01h 60h 01h 00h → CKS = 03h).
  • ID1 = control ID set on projector; ID2 = model code (device-assigned). Neither value is stated statically in this source.
  • Acknowledgement high byte by class: A0h/A1h/A2h/A3h replace the request's leading byte (00h/01h/02h/03h) on success.
  • Serial baud rate is selectable among 4800/9600/19200/38400/115200 — the source does not state which is the factory default.
  • Information updates (lamp/filter usage) are reported in one-second units but refreshed at one-minute intervals.
  • Lamp remaining life (%) may be negative if the replacement deadline is exceeded.
