Sharp/NEC LED FE009I2 104IN Control Spec

Summary

Sharp/NEC LED FE009I2 104IN projector/LED display, controlled via RS-232C (PC CONTROL D-SUB 9P) or wired/wireless LAN. Binary command protocol with hex-byte framing, checksum (low-order byte of sum of preceding bytes), and request/response structure. Spec covers 53 documented command entries.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 as switchable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated in source
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

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

Actions

# NOTE on command format: source lists commands as hex byte sequences with the
# trailing byte being the checksum (CKS = low-order 8 bits of sum of preceding
# bytes). <ID1> (control ID) and <ID2> (model code) are inserted by the
# controller before transmission per section 2.2; CKS must be recomputed when
# parameters or IDs change. Parameterized commands show the variable part in {}.

Notes

• Checksum (CKS): low-order 8 bits of the sum of all preceding bytes in the command/response frame. Must be recomputed when any byte (including parameters) changes. Worked example in source section "Example of checksum calculation".
• ID1 / ID2 framing: source section 2.2 defines ID1 (control ID) and ID2 (model code) as parameters inserted before the LEN/data part on transmission. The command bytes listed in section 3 are the logical form; full wire format requires wrapping with header + ID1 + ID2 per section 2.1 (20h <OP> <ID1> <ID2> <LEN> <DATA...> <CKS>).
• Response framing: responses use A-prefix on leading byte (e.g. POWER ON response is A2h 00h <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>).
• Error codes (ERR1, ERR2): documented combinations in source section 2.4 — e.g. 00h 00h unrecognized command, 00h 01h unsupported by model, 01h 00h invalid value, 02h 0Dh power off (command not accepted), 02h 0Eh execution failed, 02h 0Fh no authority, 03h 02h adjustment failed.
• Baud rate switchable: source lists 115200 / 38400 / 19200 / 9600 / 4800 bps. Default value not stated; pick the highest documented (115200) as the baud_rate and note the switchable range here.
• Power interlocks: commands rejected with ERR1=02h ERR2=0Dh ("command cannot be accepted because the power is off") when projector is not powered on. See 015/016 timing notes in Safety.
• Lamp usage / filter usage: time counters update at one-minute intervals even though resolution is one-second.
• Appendix "Supplementary Information by Command": referenced by multiple commands (018 input terminal values, 030-12 aspect values, 098-8 eco mode values, 097-198 sub-input values, 305-1 base model types, 319-10 input terminal). Source document provided does NOT contain the appendix pages — those enum tables are UNRESOLVED.
• Wireless LAN: source mentions a wireless LAN unit but defers to "operation manual of the wireless LAN unit" for details — not specified here.

Spec done. 53 actions match source 53 commands. Both RS-232C + TCP/7142 populated (source explicit). Appendix enums marked UNRESOLVED (not in refined source). CKS + ID1/ID2 framing explained in Notes.
