Sharp/NEC LED FA019I2 Control Spec

Summary

The Sharp/NEC LED FA019I2 is a projector controllable via RS-232C serial (PC CONTROL, D-SUB 9P) and via wired/wireless LAN using TCP port 7142. This spec covers the binary command protocol documented in the "Projector Control Command Reference Manual" (BDT140013, Revision 7.1), including power, input switching, mute, picture/volume/lens adjustment, lens memory, status queries, and eco/edge-blending/PIP control. Commands are binary hex frames with a trailing checksum byte.

Transport

# Both RS-232C serial and LAN (TCP) are explicitly documented. ID1/ID2/CKS
# framing applies identically over both transports.
protocols:
  - tcp
  - serial
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands."
serial:
  baud_rate: 115200  # supported rates: 115200/38400/19200/9600/4800 bps (source lists all five)
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Full duplex" communication mode and wires RTS<->CTS, but does not explicitly specify a flow-control setting
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

traits:
  - powerable   # inferred: POWER ON (015) / POWER OFF (016) commands present
  - queryable   # inferred: many status/information request commands present
  - levelable   # inferred: picture/volume/lens/gain adjustment commands present

Actions

# Binary frame structure (applies to every command below):
#   <class> <op> <ID1> <ID2> <LEN> [<DATA...>] <CKS>
#   - class : request class byte (00h/01h/02h/03h). Success responses use
#             20h/21h/22h/23h; error responses use A0h/A1h/A2h/A3h.
#   - op    : operation/command code.
#   - ID1   : control ID set on the projector (00h default in examples).
#   - ID2   : model code, varies by model (00h default in examples).
#             UNRESOLVED: FA019I2 model code not stated in source.
#   - LEN   : data length (bytes) following LEN.
#   - DATA  : variable data (documented per command).
#   - CKS   : checksum = low-order one byte of the sum of all preceding bytes.
# Request payloads below are copied verbatim from the source. <DATA..> and <CKS>
# are placeholders to be filled at runtime; 00h values for ID1/ID2 are the
# documented defaults.

Notes

• Command/response framing is binary hex. A leading class byte distinguishes requests (00h/01h/02h/03h) from success responses (20h/21h/22h/23h) and error responses (A0h/A1h/A2h/A3h). Example checksum: 20h 81h 01h 60h 01h 00h → sum = 103h → CKS = 03h.
• ID1 = control ID configured on the projector (00h default in examples). ID2 = model code, varies by model. The FA019I2 model code is not stated in the source; both must be set to the projector's configured values and the checksum recomputed accordingly.
• The source is a generic manual (BDT140013 Rev 7.1). Parameter value lists marked "see the Appendix Supplementary Information by Command" (input terminal values, aspect values, eco-mode values, base model type values, PIP sub-input values) are NOT present in the provided refined source and are left UNRESOLVED.
• Lamp/filter usage times are returned in one-second units but updated at one-minute intervals.
• Picture/Sound/Onscreen mute auto-clear on input-terminal switch or video-signal switch (Picture/Onscreen), and additionally on volume adjustment (Sound).
• LENS CONTROL (053): after sending a continuous-drive byte (7Fh plus / 81h minus), send 00h to stop. While the lens is driving, the same command can be reissued to change direction without an explicit stop.

Known Gaps

- "The source manual is a generic reference (BDT140013 Rev 7.1) covering multiple models; exact command/parameter support for the FA019I2 specifically (model code ID2, supported input terminals, aspect values, eco-mode values, base model type) requires the per-model \"Supplementary Information by Command\" appendix which is not present in the provided source text."
- "source states \"Full duplex\" communication mode and wires RTS<->CTS, but does not explicitly specify a flow-control setting"
- "FA019I2 model code not stated in source."
- "not in source).\""
- "eco-mode value list is in the per-model appendix, not in source"
- "numeric min/max/default not stated; returned dynamically by 060-1 GAIN PARAMETER REQUEST 3"
- "device-reported via 060-1"
- "no push/event mechanism documented in source"
- "no explicit power-on sequencing procedure or safety interlock"
- "FA019I2-specific model code (ID2), firmware version compatibility, supported input-terminal enumeration, aspect value enumeration, eco-mode value enumeration, base-model-type enumeration, and PIP sub-input value enumeration — all referenced to an appendix not included in the source."
- "serial flow_control setting (source states \"Full duplex\" and wires RTS/CTS but does not explicitly specify a flow-control mode)."
