Summary

Sharp/NEC LED FA025I2 projector control spec. Binary hex command protocol over both RS-232C serial and TCP/IP (wired/wireless LAN). Commands use framed hex payloads with checksum byte; responses carry ID1/ID2 plus data or error codes.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # "Use TCP port number 7142 for sending and receiving commands."
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 bps as selectable; 115200 shown first
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # full-duplex communication mode stated; no flow-control field in source
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred: POWER ON (015) / POWER OFF (016) commands present
- queryable    # inferred: many status/information request commands present
- levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST present

Actions

# All command payloads verbatim from source (hex bytes). ID1/ID2/CKS appear in
# the framed protocol; literal command bytes below are exactly as documented.
# Checksum (CKS) = low byte of sum of all preceding bytes.

Events

# No unsolicited notification protocol documented. Device responds only to commands.
# UNRESOLVED: no event/notification section in source.

Macros

# No multi-step command sequences explicitly documented in source.
# UNRESOLVED: populate if source contains macro sequences.

Notes

  • Baud rate is selectable among 115200/38400/19200/9600/4800 bps; 115200 listed first (likely default). Both endpoints must match.
  • Command frame: literal hex bytes; checksum (CKS) = low-order byte of sum of all preceding bytes.
  • Response frame prefixes: 20h/21h/22h/23h = success (echoes command group), A0h/A1h/A2h/A3h = error response with ERR1/ERR2.
  • ID1 = projector control ID setting; ID2 = model code (model-specific).
  • Lamp/filter usage times update at one-minute intervals despite one-second resolution.
  • Two-lamp projector models only: Lamp 2 selectors (DATA01=01h) effective.

Spec done. 53 commands, all hex payloads verbatim. Serial+TCP both documented, port 7142 explicit, no auth inferred. Appendix value tables referenced but absent → marked UNRESOLVED.

## Known Gaps

```yaml
- "input terminal value codes, aspect value codes, eco mode value codes, base model type codes, and sub input setting values are referenced to an \"Appendix: Supplementary Information by Command\" not present in this refined source. Firmware version compatibility not stated."
- "value list in Appendix not present in source"
- "no event/notification section in source."
- "populate if source contains macro sequences."
- "Appendix \"Supplementary Information by Command\" referenced multiple times (input terminal values, aspect values, eco mode values, base model type values, sub input setting values) is not present in this refined source document. Firmware version compatibility not stated. Protocol version not stated. Whether TCP connection stays persistent or per-command not stated."
