Epson EB Series Control Spec

Summary

Epson home/cinema projector control spec based on the ESC/VP21 command protocol, an ASCII-coded command set used by A/V controllers to control and monitor Epson projectors. ESC/VP21 is transport-independent; the source documents serial (RS-232C) and TCP/IP network connections (USB also supported per source, not modeled here — see Notes). Covers power, A/V mute, mute source selection, and input/source selection commands.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: null  # UNRESOLVED: TCP port not stated in source; see ESC/VP.net protocol manual
serial:
  baud_rate: 9600
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable  # inferred from PWR ON/OFF commands
- routable   # inferred from SOURCE input-routing commands
- queryable  # inferred: get command format (command + "?") documented in source section 2.2

Actions

# All command strings verbatim from source. Per-model availability varies - see Notes.

Feedbacks

- id: ack_colon
  type: enum
  values: [":"]
  description: Projector returns a colon after executing a set command.
- id: error_response
  type: enum
  values: ["ERR"]
  description: >-
    Projector returns "ERR" plus return key code (Hex 0D) and a colon when it
    receives invalid (illegal) commands.
- id: get_response
  type: string
  description: >-
    Get commands (command + "?") return a response parameter after execution.
    Specific get command codes are not enumerated in this source.
  # UNRESOLVED: per-command get response value sets not stated in source

Variables

# UNRESOLVED: no settable continuous parameters (volume/gain/brightness) documented in source.
# Set commands use fixed params (ON, OFF, 21) or step params (INC, DEC, INIT) but no
# parameterized command with a documented range appears in the command tables.

Events

# UNRESOLVED: no unsolicited notifications documented in source.

Macros

- id: enable_pwr_on_tw200
  label: Enable PWR ON on TW200/TW200H
  steps:
    - "Turn on the projector"
    - "Send SPWRLVL 01 after the projector enters a state where it can receive ESC/VP21 commands"
    - "Turn off the projector once; PWR ON works after the projector reaches standby state"
  notes: Explicit two-step procedure from source footnote (*1).

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or
# power-on sequencing requirements beyond the TW200/TW200H PWR ON enablement procedure (operational, not safety).

Notes

• ESC/VP21 command codes are ASCII; protocol is transport-independent (serial, USB, or TCP/IP network per source). USB transport is not modeled in this spec (no protocol enum for it; no USB comm parameters in source).
• TCP/IP network control requires establishing a TCP session first; details deferred to the ESC/VP.net protocol manual, which is not part of this source.
• Serial: select RS-232C at Advanced Setting of the menu; D-Sub 9pin connector, projector input Control (RS-232C).
• Set commands support fixed parameters (e.g. ON, OFF) and step parameters: INC (increment by one), DEC (decrement by one), INIT (initialize).
• Null command (Hex 0D) returns a colon and can confirm the projector is in operation.
• Per-model command availability varies significantly; source provides per-model OK/- matrices across the SOURCE tables (e.g. SOURCE 14/15 are get-only on TW420/HC700/HC705HD per footnote (*7)).
• TW500: to validate PWR ON, "Network Monitoring" of "Operation" in "Setting" menu must be set to ON, then power-cycle once.
• TW10/TW10H do not support the User Logo function (MSEL02).

Known Gaps

- "TCP port number and network session details not in this source; source defers to the ESC/VP.net protocol manual."
- "source guide is titled \"for Home Projectors\" and lists TW/HC/PowerLite models; applicability to business \"EB Series\" models is asserted by the input metadata, not by this source document."
- "TCP port not stated in source; see ESC/VP.net protocol manual"
- "per-command get response value sets not stated in source"
- "no settable continuous parameters (volume/gain/brightness) documented in source."
- "no unsolicited notifications documented in source."
- "source contains no safety warnings, interlock procedures, or"
