# UNRESOLVED: source documents a generic "?" get-command format (Section 2.2) and lists
# specific command codes, but does not enumerate which commands are queryable on
# CH-QL3000W. Construct GET-style actions only after confirming against the
# CH-QL3000W-specific manual.

Feedbacks

# Source documents generic response format: ":" on success, "ERR" + CR (Hex 0D) + ":"
# on illegal command (Sections 2.1, 2.4).
- id: command_ack
  type: enum
  values: [ok, error]
  notes: "':' indicates success; 'ERR\\r:' indicates illegal command."

Variables

# UNRESOLVED: source describes INC/DEC/INIT step parameters (Section 2.1) but does not
# enumerate which commands on CH-QL3000W accept these step parameters.

Events

# UNRESOLVED: source does not describe unsolicited notification messages.

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not document safety warnings, interlocks, or power-on
# sequencing specific to CH-QL3000W.

Notes

• Source is the generic ESC/VP21 manual; CH-QL3000W is not listed in the "Applicable models" section. Treat the action list as a candidate set requiring verification against the CH-QL3000W-specific protocol guide.
• Serial communication per source Appendix 5.1: RS-232C, 9600 bps, 8N1, no flow control, D-Sub 9-pin. The "RS-232C" option must be selected under Advanced Setting in the projector's menu.
• Command format: ASCII codes terminated by CR (Hex 0D). Set command = COMMAND PARAM; Get command = COMMAND?. Success response = :. Illegal command response = ERR\r:. Null command (CR alone) returns : and can be used to confirm the projector is responsive.
• Source references an external "ESC/VP.net protocol manual" for TCP/IP session setup; that document is not included in the provided source, so TCP port, base URL, and any TCP-specific framing remain unresolved.
• USB connection is documented as supported by ESC/VP21 in principle but no USB-specific parameters are stated in the provided source.

Known Gaps

- "CH-QL3000W is not explicitly listed in the \"Applicable models\" section of the source; commands below are ESC/VP21 generic. Verify against the dedicated CH-QL3000W manual before relying on any action."
- "source mentions RS-232C menu setting required"
- "TCP port and any base URL not stated in source"
- "source documents a generic \"?\" get-command format (Section 2.2) and lists"
- "source describes INC/DEC/INIT step parameters (Section 2.1) but does not"
- "source does not describe unsolicited notification messages."
- "source does not describe multi-step macro sequences."
- "source does not document safety warnings, interlocks, or power-on"
- "TCP port not stated in source. UNRESOLVED: auth credentials not stated in source. UNRESOLVED: firmware compatibility not stated in source. UNRESOLVED: full CH-QL3000W command set not stated in source (only generic ESC/VP21 applicable to legacy Epson projector families)."
