Sharp/NEC V551 Control Spec

Summary

Projector control spec for the Sharp/NEC V551. Covers RS-232C serial and wired/wireless LAN (TCP) control using a binary, checksum-framed command protocol (document BDT140013 Rev 7.1). Supports power, input switching, mutes, lens/shutter, picture/volume adjust, status queries, and lens memory control.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # source lists all as switchable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; pin table shows RTS/CTS cross-wired but "Communication mode: Full duplex" is the only mode stated
addressing:
  port: 7142  # source: "Use TCP port number 7142"
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON / POWER OFF commands present
  - routable        # inferred: INPUT SW CHANGE command present
  - queryable       # inferred: many status request commands present
  - levelable       # inferred: PICTURE ADJUST / VOLUME ADJUST present

Actions

# Commands use binary frames with checksum (CKS = low byte of sum of all
# preceding bytes). <ID1> = control ID, <ID2> = model code. Parameterized
# DATA?? fields shown as placeholders. All payloads verbatim from source.

Events

# No unsolicited notifications documented. All responses are request/response.
# UNRESOLVED: none documented in source.

Macros

# No multi-step sequences explicitly documented as macros.
# UNRESOLVED: none documented in source.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    note: "While POWER ON is executing, no other command can be accepted. (source §3.2)"
  - command: power_off
    note: "While POWER OFF is executing (including cooling time), no other command can be accepted. (source §3.3)"
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements beyond the two command-lockout notes above.

Notes

• Frame format: All commands/responses are hex byte streams. Layout: <CMD> <SUB> <ID1> <ID2> <LEN> <DATA...> <CKS> (per §2.1/2.2). Request frames prefix 00h-03h; success-response prefixes are 20h/21h/22h/23h; error-response prefixes are A0h/A1h/A2h/A3h.
• Checksum (CKS): low-order byte of the sum of all preceding bytes (§2.2).
• ID1: projector control ID. ID2: model code (varies by model, not enumerated in this source).
• Error responses: carry ERR1/ERR2 byte pair; full error-code table in source §2.4 (29 codes, e.g. 02h 0Dh = "command cannot be accepted because power is off").
• Lens drive: after sending continuous-direction codes (7Fh/81h), drive must be stopped explicitly with 00h (§3.22).
• Usage-time resolution: lamp and filter usage times are stored in seconds but only refreshed by the projector at 1-minute intervals.

Spec above. 56 commands enumerated, all source rows covered. Gaps marked `UNRESOLVED` — biggest one: referenced Appendix ("Supplementary Information by Command") absent from excerpt, so input-terminal/eco/aspect/sub-input/base-model value maps missing.

## Known Gaps

```yaml
- "input terminal value map, eco mode value map, aspect value map, sub-input value map, and base-model-type value map are referenced in an \"Appendix: Supplementary Information by Command\" that is not present in this source."
- "flow control not stated; pin table shows RTS/CTS cross-wired but \"Communication mode: Full duplex\" is the only mode stated"
- "eco mode value enum is in Appendix, not in this source"
- "none documented in source."
- "source contains no explicit safety warnings, interlock procedures,"
- "ID2 model code for V551 not stated."
- "input-terminal value map (used by 018 INPUT SW CHANGE and 319-10 AUDIO SELECT SET) referenced but absent from this excerpt."
- "eco-mode value map referenced but absent."
- "aspect value map referenced but absent."
- "sub-input setting value map (PIP/PbP) referenced but absent."
- "base-model-type value map referenced but absent."
- "serial flow_control not stated (RTS/CTS pins present in connector table but mode not declared)."
- "firmware version compatibility not stated."
- "voltage / power specs not present in this control-protocol excerpt."
