Summary

Serial (RS-232C) control protocol for Panasonic TH-xxPF50W series plasma displays. Commands use STX/ETX framing with a 4-byte device ID, 3-byte command code, and optional parameters. Covers power, input selection, picture adjustments, geometry correction, lamp management, and OSD control.

Frame Format

description: STX (0x02) + ID (4 bytes) + ';' + Command (3 bytes) [ + ':' + Parameters ] + ETX (0x03)
notes:
  - ID "ADZZ" = broadcast to all units (ID ALL)
  - IDs AD01-AD64 for individual units (ID 1-64)
  - IDs AD0A-AD0Z for groups (A-Z)
  - Wait >= 0.5s between commands after receiving response
  - Set timeout >= 10s for response
  - Wait 60s after lamp illumination before sending commands

Traits

traits:
  - powerable     # PON/POF power on/off commands
  - queryable     # inferred from response callbacks; query commands likely on later pages
  - routable      # IIS input select commands
  - levelable     # VCO/VTN/VCN/VBR/OZH/OZV and many other continuous adjustment commands

    description: >
      Each command returns a callback when accepted.
      Response format: STX + command_code [+ ':' + parameters] + ETX.
      Error responses: ER401 (command not acceptable / REMOTE2 conflict / parameter error),
      ER402 (parameter range error).
    values:
      - ER401
      - ER402

  # UNRESOLVED: query commands (QPW etc.) documented on later pages (49-193) not yet extracted

Variables

# UNRESOLVED: query-type commands returning current values likely on pages 49-193

Events

# No unsolicited events documented in extracted source sections.

Macros

# No multi-step macro sequences explicitly described in source.

Safety

confirmation_required_for: []
interlocks: []
notes:
  - Wait >= 60s after lamp starts illuminating before sending commands
  - Wait >= 0.5s between consecutive commands (after receiving response)
  - Set timeout >= 10s for command responses
  - REMOTE2 takes priority over serial commands; conflicting commands return ER401
# UNRESOLVED: full safety/interlock procedures may be in unextracted pages

Notes

  • Commands use 3-byte ASCII codes (e.g. PON, OFZ, IIS).
  • Parameters are right-justified with leading zeros (e.g. value 1 = 00001).
  • Subcommand format uses 5-byte subcommand + 1-byte operation (= for set, _ for add) + 1-byte sign (+/-) + 5-byte value.
  • Device IDs: ADZZ = broadcast, AD01–AD64 = individual, AD0A–AD0Z = groups A–Z.
  • Group responses controlled by RS232C RESPONSE(ID GROUP) setting.
  • Error codes: ER401 (unacceptable command / REMOTE2 conflict), ER402 (parameter error / out of range).
  • Source document is 193 pages; this spec covers commands from pages 1–48 only.
