Summary

Sharp/NEC Pnm322 projector control spec covering RS-232C serial and TCP/IP (LAN) control. Binary hex command protocol with checksum byte; supports power, input switching, mute, picture/volume/lens adjust, lens memory, status queries, and edge blending.

Transport

protocols:
  - serial
  - tcp

Traits

traits:
  - powerable       # inferred from POWER ON/OFF commands
  - queryable       # inferred from numerous REQUEST query commands
  - levelable       # inferred from PICTURE/VOLUME/LENS adjust commands
  - routable        # inferred from INPUT SW CHANGE command

Events

# UNRESOLVED: no unsolicited notifications documented in source. Device is poll-only.

Macros

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

Safety

confirmation_required_for:
  - power_off  # source notes cooling time during which no commands accepted
interlocks:
  - "POWER ON: no other command accepted while power-on in progress"
  - "POWER OFF: no other command accepted during power-off including cooling time"
  - "Error DATA09 Bit1: interlock switch open is a defined error condition"
# UNRESOLVED: source contains no explicit power-on sequencing requirements or external interlock procedures beyond the error bitmask definition.

Notes

  • Command/response framing: hex byte strings. Frame uses leading command-class byte (00h–03h for requests, 20h–23h for success responses, A0h–A3h for error responses).
  • Parameters ID1 (control ID), ID2 (model code), CKS (checksum) are common to all commands.
  • Checksum = low-order 8 bits of sum of all preceding bytes.
  • Error responses carry ERR1+ERR2 pair — see source error code list (00h/00h unrecognized, 02h/0Dh power off, etc.).
  • Signal list number returned is 1 less than practical value (add 1).
  • Lamp/filter usage info updates at 1-minute intervals despite 1-second resolution.
  • Appendices referenced ("Supplementary Information by Command") are not in this source extract — values for input terminal, eco mode, base model type, and sub input are UNRESOLVED.

Spec above. 53 actions enumerated — every command row in source 2. Command List covered. Hex payloads verbatim. Ports/serial config direct from source. UNRESOLVED markers on gaps (baud default, appendix values, firmware).
