Summary

Sharp/NEC Ld Fe122 U projector. Binary hex control protocol over RS-232C serial and wired/wireless LAN (TCP). Commands are framed byte sequences with a trailing checksum (CKS = low-order byte of the sum of all preceding bytes). Source: Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [4800, 9600, 19200, 38400, 115200]  # source lists all five as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not in the comm-conditions table; RTS/CTS pins are cross-wired in the D-SUB 9P pinout but the setting is not specified
addressing:
  port: 7142  # stated for LAN command send/receive
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands (015, 016)
  - queryable    # inferred: numerous status/information request commands
  - levelable    # inferred: PICTURE ADJUST / VOLUME ADJUST / OTHER ADJUST (030-1/2/15)
  - routable     # inferred: INPUT SW CHANGE / AUDIO SELECT SET / PIP sub-input (018, 319-10, 098-198)

Actions

# Framing note: a command's trailing byte <CKS> is the checksum = low-order one
# byte of the sum of ALL preceding bytes (incl. the leading type/opcode bytes and
# any ID1/ID2 shown as 00h 00h). Literal commands below carry the documented CKS
# verbatim; parameterized commands show <CKS> as a computed field.

Notes

  • Wire format: each command/response is a frame of hex bytes. Request frames use leading type bytes (00h-03h); success responses use 20h/21h/22h/23h with echoed <ID1> <ID2>; error responses use A0h/A1h/A2h/A3h with <ERR1> <ERR2> <CKS>.
  • Checksum (CKS) = low-order one byte of the sum of all preceding bytes in the frame. Worked example from source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • ID1 = control ID set on the projector; ID2 = model code (varies by model). Commands show these as 00h 00h (defaults); responses echo actual values.
  • Lamp usage time is obtainable in one-second units but updated at one-minute intervals.
  • 01h (Lamp 2) in lamp commands is effective only on two-lamp projector models.

Spec cooked. 53 action, all row from source command list. Hex byte verbatim, checksum kept. Transport dual: serial+tcp(7142). UNRESOLVED flag on appendix enum + flow_control + firmware.

Known Gaps

- "input terminal / aspect / eco-mode / sub-input / base-model-type value enumerations live in an \"Appendix: Supplementary Information by Command\" not included in the refined source. Parameter values for these fields are therefore unresolved."
- "flow control not in the comm-conditions table; RTS/CTS pins are cross-wired in the D-SUB 9P pinout but the setting is not specified"
- "full value list is in source Appendix 'Supplementary Information by Command' not present here. CKS computed.\""
- "value list in source Appendix not present here.\""
- "eco-mode value enumeration is in source Appendix not present here"
- none
- "populate from source, or remove section if not applicable"
- "input-terminal, aspect, eco-mode, sub-input, and base-model-type value enumerations are in a source Appendix (\"Supplementary Information by Command\") not present in the refined input."
- "flow_control setting not specified in the comm-conditions table."
- "firmware version compatibility not stated in source."
