Sanyo PLC-WXE45 RS-232 / IP control commands

Summary

RS-232C serial control spec for the Sanyo PLC-WXE45 projector. Commands are 2-character ASCII mnemonics sent as "C" COMMAND [CR]; status queries are "CR" COMMAND [CR]. One command per line, capital letters only, terminated by carriage return (0x0D).

Feedbacks

# Status Read response values per source.
# Each Feedback corresponds to one status read command's acceptable response.
- id: status
  type: enum
  values:
    - "00"   # Power ON
    - "80"   # Standby
    - "40"   # Countdown in process
    - "20"   # Cooling Down in process
    - "10"   # Power Failure
    - "28"   # Cooling Down in process due to Temperature Anomaly
    - "88"   # Coming back after Temperature Anomaly
    - "24"   # Power Save / Cooling Down in process
    - "04"   # Power Save
    - "21"   # Cooling Down in process after Power off due to lamp failure
    - "81"   # Standby after Cooling Down due to lamp failure

- id: input_mode
  type: enum
  values:
    - "1"    # Computer 1 selected
    - "2"    # Computer 2 selected
    - "3"    # Video selected

- id: setting
  type: enum
  values:
    - "11"   # Normal Screen Setting
    - "10"   # Rear & Ceiling ON
    - "01"   # Rear ON
    - "00"   # Ceiling ON

- id: lamp_mode
  type: enum
  values:
    - "00"   # Light is out
    - "01"   # Light is on

Variables

# Free-form numeric/string readouts (not enum).
- id: lamp_time_hours
  type: integer
  description: Total lamp running hours (5-digit zero-padded, e.g. "00410" = 410 hours). Not actual hours, but Eco-mode-corresponding value.

- id: temperature_sensors
  type: string
  description: Three temperatures in form "%1_%2_%3" where each field is "00.0" or "-00.0" or "E00.0" (E prefix on sensor hardware error). Example: "_31.5_35.2_33.4".

Events

# UNRESOLVED: source does not describe unsolicited notifications; projector only returns responses to commands.

Macros

# UNRESOLVED: source does not describe multi-step sequences.

Safety

confirmation_required_for:
  - power_off  # C02 displays "Power OFF?" and must be sent a second time to actually shut down
interlocks: []
# UNRESOLVED: source describes operational gating (commands disabled in Cooling Down / Abnormal Temperature / Power Save states) but not formal safety interlocks.

Notes

Baud rate: initial 19200, switchable to 9600 in service mode. Source supports both values.
Command framing: every command is a single line starting with "C" (functional) or "CR" (status read) and terminated by CR (0x0D). Commands must be capital A-Z.
Inter-command delay: 100 ms minimum; wait for ACK before issuing next command.
Initialization: ~5 seconds after AC plug-in during which the projector ignores all commands.
Timeout: if a single command line takes >1 s to arrive, the buffer is cleared and the command is not executed.
Acceptable response: ACK (0x06) + CR. Undecodable response: "?" + CR.
Status response length varies by command (see CR0/CR1/CR3/CR4/CR6/CR7 in source).
C02 power off is a two-step: first send displays "Power OFF?", second send executes shutdown. C01 is the quick power off variant (no confirmation).
D.Zoom mode must be exited before screen-size commands (C0F/C10) are accepted.

matched_actions: 60
action_count: 60
confidence: medium
summary: "All 60 spec actions matched literally in source command tables; all transport parameters (19200 baud, 8 data bits, no parity, 1 stop bit, no flow control) verified verbatim. (7 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "cable pinout is referenced (D-Sub 9 pin ↔ Mini 8 pin) but the exact wiring is not described in the refined source."
- "source does not describe unsolicited notifications; projector only returns responses to commands."
- "source does not describe multi-step sequences."
- "source describes operational gating (commands disabled in Cooling Down / Abnormal Temperature / Power Save states) but not formal safety interlocks."
- "D-Sub 9 ↔ Mini 8 pin cable pinout is referenced but the wiring is not in the refined source."
- "firmware version compatibility range not stated."
- "service-mode baud rate change procedure not documented in refined source."
