Sharp/NEC LED FE031I2 Control Spec

Summary

The Sharp/NEC LED FE031I2 is an LED projector controllable via RS-232C serial (PC CONTROL D-SUB 9P) and wired/wireless LAN (TCP). This spec covers the binary frame command set documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mutes, picture/volume/aspect adjustment, lens control & memory, status queries, and LAN/PIP/edge-blending configuration. Commands are binary hex frames with a trailing additive checksum byte.

Transport

# Source documents both a serial (RS-232C) and a LAN (TCP) interface.
# Frame format (binary hex): [type] [cmd] [00h] [00h] [len] [data...] [checksum]
# Responses prefix: 20h/21h/22h/23h (success), A0h/A1h/A2h/A3h (error).
# Checksum = low-order byte of sum of all preceding bytes (see Notes).
protocols:
  - tcp
  - serial
addressing:
  port: 7142  # stated: "Use TCP port number 7142 for sending and receiving commands."
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source lists multiple selectable rates
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated; communication mode stated as "Full duplex"
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred from 015 POWER ON / 016 POWER OFF
- queryable    # inferred from numerous status/information request commands
- routable     # inferred from 018 INPUT SW CHANGE / 319-10 AUDIO SELECT SET
- levelable    # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST

Actions

# All command bytes are VERBATIM from source. <CKS> = computed checksum byte.
# Parameterized commands show variable bytes in braces; fixed commands show full literal frame.

Events

# UNRESOLVED: no unsolicited notifications documented in source. All state is polled via request commands.

Macros

# UNRESOLVED: no multi-step sequences documented explicitly in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings or interlock procedures in source.
# Notes from source: POWER ON/OFF block all other commands during transition (incl. cooling time);
# 009 ERROR STATUS DATA09 Bit1 reports "interlock switch is open" as an error condition, but no
# procedural interlock sequence is documented here.

Notes

• Frame format (binary): command [type] [cmd] 00h 00h [LEN] [DATA...] [CKS]; success response [20h|21h|22h|23h] [cmd] [ID1] [ID2] [LEN] [DATA...] [CKS]; error response [A0h|A1h|A2h|A3h] [cmd] [ID1] [ID2] 02h [ERR1] [ERR2] [CKS].
• Checksum (CKS): low-order one byte of the sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
• Common params: ID1 = projector control ID; ID2 = model code; LEN = data length following LEN; DATA?? = variable data; ERR1/ERR2 = error codes (see section 2.4 list).
• Error codes (ERR1/ERR2): 00h/00h unrecognized command; 00h/01h not supported by model; 01h/00h invalid value; 01h/01h invalid input terminal; 01h/02h invalid language; 02h/00h memory allocation error; 02h/02h memory in use; 02h/03h value cannot be set; 02h/04h forced onscreen mute on; 02h/06h viewer error; 02h/07h no signal; 02h/08h test pattern/filter displayed; 02h/09h no PC card; 02h/0Ah memory operation error; 02h/0Ch entry list displayed; 02h/0Dh command rejected (power off); 02h/0Eh execution failed; 02h/0Fh no authority; 03h/00h incorrect gain number; 03h/01h invalid gain; 03h/02h adjustment failed.
• Usage-time granularity: lamp/filter usage time reported in seconds but updated at 1-minute intervals.
• Serial pinout: PC CONTROL D-SUB 9P cross cable — Pin2 RxD, Pin3 TxD, Pin5 GND, Pin7 RTS, Pin8 CTS.

summary: "All 53 spec actions matched verbatim against source command reference; transport parameters verified; complete bidirectional coverage. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "source is a generic projector command reference; model name \"FE031I2\" is operator-supplied and does not appear verbatim in the source text. Firmware version compatibility, voltage/power specs, and per-model input terminal value tables (referenced as \"Supplementary Information by Command\" appendix) are not present in this refined excerpt."
- "flow control not stated; communication mode stated as \"Full duplex\""
- "exact min/max not stated; limits queryable via 060-1"
- "numeric ranges for all adjustments not stated in source; runtime limits obtainable via 060-1 GAIN PARAMETER REQUEST 3."
- "no unsolicited notifications documented in source. All state is polled via request commands."
- "no multi-step sequences documented explicitly in source."
- "no explicit safety warnings or interlock procedures in source."
- "model name \"LED FE031I2\" supplied by operator, not found verbatim in source text (generic projector manual)."
- "input terminal value tables, eco mode value tables, aspect value tables, sub-input setting values, and base model type values are referenced as an appendix (\"Supplementary Information by Command\") not included in this refined excerpt."
- "numeric adjustment ranges (min/max) for brightness/contrast/color/hue/sharpness/volume/lamp-adjust not stated; must be queried at runtime via 060-1."
- "serial flow control not stated (only \"Full duplex\" communication mode stated)."
- "firmware version compatibility not stated in source."
