Sharp/NEC LED FA019I2 110 Control Spec

Summary

Sharp/NEC LED FA019I2 110 large-format LED display, controlled via the Sharp/NEC projector binary control protocol described in reference manual BDT140013 Revision 7.1. The protocol supports both RS-232C serial and TCP/IP (wired or wireless LAN) transports using a framed hexadecimal command/response format with a trailing checksum byte. This spec enumerates all 53 commands documented in the source manual.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists supported rates 115200/38400/19200/9600/4800; default not stated, 9600 shown as one option

framing:
  description: |
    Hexadecimal framed protocol. Commands begin with a class lead byte
    (00h/01h/02h/03h) followed by a command code byte, then fixed 00h 00h bytes,
    a LEN byte (data length), the DATA bytes, and a checksum byte (CKS).
    Responses use lead bytes 20h/21h/22h/23h (success) or A0h/A1h/A2h/A3h (error).
  checksum: |
    CKS = low-order 8 bits of the sum of all preceding bytes (including lead byte
    and any ID1/ID2 in responses). Example: 20h+81h+01h+60h+01h+00h = 103h -> CKS=03h.
  response_parameters:
    ID1: "Control ID set on the projector (echoed in responses; not present in commands sent to projector)"
    ID2: "Model code, varies by model (echoed in responses; not present in commands sent to projector)"
    ERR1: "Error code byte 1 (see error code list in Notes)"
    ERR2: "Error code byte 2 (see error code list in Notes)"

Traits

traits:
  - powerable       # inferred from 015 POWER ON / 016 POWER OFF
  - queryable       # inferred from many REQUEST commands returning state
  - levelable       # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST
  - routable        # inferred from 018 INPUT SW CHANGE / 319-10 AUDIO SELECT SET

Notes

Protocol framing. All command/response bytes are hexadecimal. Command (sent to projector) format: <lead> <cmd> 00h 00h <LEN> <DATA...> <CKS>. Lead byte determines class: 00h=class-0 (most queries via 85h/BFh/D0h), 01h=class-1 (freeze control), 02h=class-2 (power/mute/input/shutter/lens/remote), 03h=class-3 (picture adjust/information requests/setters). Response success lead bytes: 20h/21h/22h/23h. Response error lead bytes: A0h/A1h/A2h/A3h.

Checksum (CKS). Low-order 8 bits of the sum of all preceding bytes (lead byte through last DATA byte, plus ID1/ID2 in responses). Worked example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → CKS = 03h.

Error code list (ERR1 / ERR2).

Error status bitmap (009. ERROR STATUS REQUEST, DATA01–DATA09). Bit set to 1 = error.

• DATA01: Bit0 Cover error; Bit1 Temperature error (bi-metallic strip); Bit3 Fan error; Bit4 Fan error; Bit5 Power error; Bit6 Lamp/lamp1 off or backlight off; Bit7 Lamp/lamp1 in replacement moratorium.
• DATA02: Bit0 Lamp/lamp1 usage time exceeded limit; Bit1 Formatter error; Bit2 Lamp 2 off; Bit6 Lamp 2 in replacement moratorium; Bit7 Lamp 2 usage time exceeded limit.
• DATA03: Bit1 FPGA error; Bit2 Temperature error (sensor); Bit3 Lamp/lamp1 not present; Bit4 Lamp/lamp1 data error; Bit5 Mirror cover error; Bit6 Lamp 2 in replacement moratorium; Bit7 Lamp 2 usage time exceeded limit.
• DATA04: Bit0 Lamp 2 not present; Bit1 Lamp 2 data error; Bit2 Temperature error due to dust; Bit3 Foreign matter sensor error; Bit5 Ballast communication error; Bit6 Iris calibration error; Bit7 Lens not installed properly.
• DATA09 (Extended status): Bit0 Portrait cover side is up; Bit1 Interlock switch is open; Bit2 System error (Slave CPU); Bit3 System error (Formatter).
• DATA05–08, DATA10–12: Reserved for the system.

RS-232C wiring. PC CONTROL port is D-SUB 9P. Cross cable: pin2(RxD)↔TxD, pin3(TxD)↔RxD, pin5(GND)↔GND, pin7(RTS)↔CTS, pin8(CTS)↔RTS.

LAN. Wired RJ-45 supports 10/100 Mbps auto-negotiable (IEEE 802.3 / 802.3u). Wireless LAN requires a separate wireless LAN unit (see device operation manual). TCP port 7142 for command transport.

Signal list number quirk. INPUT STATUS REQUEST returns a value that is 1 less than the practical signal list number; add 1 to obtain the actual number.

Usage time resolution. Lamp usage and filter usage times are obtained in 1-second units but are only updated on the projector at 1-minute intervals.

Known Gaps

- "The source manual is a generic Sharp/NEC projector command reference (BDT140013 Rev 7.1) and does not name the LED FA019I2 110 explicitly; model association is operator-asserted. Several DATA value tables (input terminal list, eco mode values, aspect values, base model type values, sub-input values) reference an \"Appendix: Supplementary Information by Command\" that is not present in the refined source text. ID2 model code value for this specific model is not stated."
- "eco mode values deferred to Appendix not in source\""
- "base model type values deferred to Appendix not in source\""

- "Default baud rate (which of 4800/9600/19200/38400/115200 is factory default) not stated in source; 9600 entered as a plausible default but should be verified on-device."
- "Firmware version compatibility for these commands not stated in source."
- "Source manual BDT140013 Rev 7.1 is a generic Sharp/NEC projector reference; explicit confirmation that every listed command applies to the LED FA019I2 110 specifically is not in the source text. Some commands (e.g. Lamp 2 variants) clearly apply only to multi-lamp models and may return ERR1=00h ERR2=01h (not supported) on this device."
