Summary

Serial (RS-232C) control protocol for Panasonic PT-BW, PT-BX, PT-VW, PT-VX, and PT-44xC series projectors. Commands use STX/ETX framing with 3-character command codes and optional parameters. Covers power, input selection, picture adjustment, lens control, keystone correction, geometry, lamp management, and extensive query commands.

Transport

protocols:
  - serial
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred from PON/POF power commands
- routable     # inferred from IIS input select commands
- queryable    # inferred from QPW/QFZ/QSH/QIN etc. query commands
- levelable    # inferred from VCO/VCN/VBR color/contrast/brightness commands

Events

# UNRESOLVED: unsolicited event notifications not documented in source excerpt

Macros

# UNRESOLVED: no multi-step macro sequences described in source

Safety

confirmation_required_for: []
interlocks: []
# Note: REMOTE2 has priority over serial commands; ER401 returned when REMOTE2 conflicts.
# Note: Commands may not execute during lamp warm-up (wait 60s after light source starts).
# Note: Wait 0.5s between consecutive commands after receiving response.
# Note: Set timeout to 10s or longer.

Notes

  • Command frame format: STX (0x02) + ID (4 bytes) + ';' + Command (3 bytes) + [':' + Parameters] + ETX (0x03).
  • ID field uses 4-byte ASCII strings: ADZZ (ALL), AD01-AD64 (individual), AD0A-AD0Z (groups A-Z).
  • Subcommand format uses 5-byte subcommand + 1-byte operation (= set, _ add) + 1-byte sign (+/-) + 5-byte parameter value.
  • Error responses: ER401 (command rejected / REMOTE2 active / invalid state), ER402 (parameter out of range).
  • Parameters are right-justified, zero-padded (e.g. value 1 → 00001).
  • Source covers 200+ basic control commands (§2.1–2.229) and 80+ query commands (§2.262–2.350+).
