Epson PowerLite 108 107 970 109W 980W 990U W39 Control Spec

Summary

Epson home projector controlled via the ESC/VP21 ASCII command protocol over RS-232C serial, USB, or TCP/IP network. This spec covers power, A/V mute, source selection, and no-signal display commands, plus the serial communication parameters stated in the source guide.

  values: [":"]
  notes: "Projector returns a colon after executing a set command."

- id: get_command_response
  type: string
  # UNRESOLVED: response parameter format per command not enumerated in source
  notes: "Projector returns a response parameter after executing a get command (command + '?')."

- id: null_command_ack

  notes: "Projector returns a colon in response to the null command (0x0D)."

- id: error_response

  notes: "Projector returns 'ERR' followed by a return key code (Hex 0D) and a colon when it receives invalid commands."

Variables

# No settable non-discrete parameters documented in source. Set commands use
# fixed parameters (ON/OFF, signal names) or step parameters (INC/DEC/INIT);
# no command using a step parameter is enumerated in the source command tables.

Events

# No unsolicited notifications documented in source.

Macros

- id: enable_pwr_on_tw200_tw200h
  label: Enable PWR ON on TW200/TW200H
  steps:
    - "Turn on the projector"
    - "After the projector reaches the condition where it can receive ESC/VP21 commands, send SPWRLVL 01"
    - "Turn off the projector once"
    - "PWR ON works after the status becomes the standby state"
  notes: "From source footnote (*1). Model-specific; not applicable to most models."

- id: enable_pwr_on_tw500
  label: Enable PWR ON on TW500
  steps:
    - "Set Network Monitoring of Operation in the Setting menu to ON"
    - "Turn off the projector once"
    - "PWR ON works after the status becomes the standby state"
  notes: "From source footnote (*1). Model-specific."

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings or interlock procedures.
# Source references a 'note4' on the PWR OFF row whose text is absent from the document.

Notes

• ESC/VP21 commands are ASCII; controllable via serial, USB, or TCP/IP network. USB is documented as a valid transport but is not representable in the protocols enum used by this spec format.
• Serial setup: select RS-232C at Advanced Setting of the projector menu. Connector D-Sub 9 pin; projector input Control (RS-232C).
• Set command parameters are either fixed (e.g. ON, OFF, 21) or step parameters: INC (increment by one), DEC (decrement by one), INIT (initialize).
• Get command format is "command + ?"; no concrete get command instances are enumerated in the source tables, so none are listed as actions.
• Command availability differs per model — the source marks each SOURCE variant OK/- per model family. Verify against the target PowerLite models before use.

Verification Summary

verdict: verified
checked_at: 2026-09-10T22:17:46.245Z
matched_actions: 49
action_count: 49
confidence: medium
summary: "All 49 wire-literal commands (PWRON, PWROFF, MUTE ON/OFF, MSEL00-02, SPWRLVL 01, 0x0D, and 40 SOURCE variants) appear verbatim in the source; transport params 9600/8/N/1 match. (9 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "the source is the \"ESC/VP21 Command User's Guide for Home Projectors\" and its Applicable Models list (section 3) enumerates older TW/HC/PC-series models (TW100...TW9000W) but does NOT explicitly name PowerLite 108/107/970/109W/980W/990U/W39. Command availability per model varies in the source tables; verification against the actual PowerLite units is required."
- "TCP/IP control mentioned but port/base URL not stated — source defers to a separate \"ESC/VP.net protocol manual\" not included here."
- "USB control mentioned but no USB transport details given beyond a reference to the Appendix."
- "TCP port not stated in source (ESC/VP.net manual referenced but not provided)"
- "response parameter format per command not enumerated in source"
- "source contains no explicit safety warnings or interlock procedures."
- "TCP port and ESC/VP.net framing not stated in source."
- "firmware version compatibility not stated in source."
- "target PowerLite 108/107/970/109W/980W/990U/W39 models not listed in the source's Applicable Models section."
