Summary

Sharp/NEC LED FE019I2 110 projector. Binary control protocol over RS-232C serial and TCP/IP LAN (port 7142). Spec covers power, input switch, mute, picture/volume/aspect adjust, shutter, lens control + memory, status/information queries, eco mode, PIP/PbP, edge blending, audio select. Commands are hex byte sequences with ID1 (control ID), ID2 (model code), and CKS (checksum) parameters.

Variables

# UNRESOLVED: source does not define standalone settable variables distinct from the
# parameterized actions above (picture/volume/aspect/gain are action-driven).
# Remove if not applicable.

Events

# UNRESOLVED: source describes no unsolicited notifications. All responses are
# command-initiated. Populate if device emits async events (not documented here).

Macros

# UNRESOLVED: source describes no explicit multi-step command sequences. Remove if not applicable.

Safety

confirmation_required_for: []
interlocks:
  - "During POWER ON execution, no other command accepted (source §3.2)."
  - "During POWER OFF execution incl. cooling time, no other command accepted (source §3.3)."
# UNRESOLVED: no power-on sequencing voltage/current specs, no interlock procedures
# beyond the command-acceptance windows above. Error bitfield (009 command) reports
# cover error, temperature error, fan error, interlock switch open, foreign matter
# sensor - but no mitigation procedures documented.

Notes

  • Commands are binary hex byte frames, not ASCII. Each frame: <lead> <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>. Lead byte 02h/03h/00h/01h = command group; response lead 2Xh = success, AXh = error.
  • ID1 = control ID set on projector (must be substituted). ID2 = model code, varies by model (UNRESOLVED: exact value for FE019I2 110 not in source).
  • CKS checksum = low-order byte of sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
  • Response lead bytes by group: 20h/21h/22h/23h = success (mirrors cmd group), A0h/A1h/A2h/A3h = error.
  • Picture/Sound/Onscreen mute auto-clear on input/video signal switch; sound mute also clears on volume change.
  • Lamp/filter usage times returned in seconds, updated at 1-minute intervals.
  • Lens control: continuous-drive (7Fh/81h) requires explicit stop (00h).
  • Input terminal values, aspect values, eco mode values, base model types, sub input values reference an "Appendix: Supplementary Information by Command" not included in this source extract — those enum tables are UNRESOLVED.

Spec ready. 53 actions, all hex payloads verbatim. Gaps marked `<!-- UNRESOLVED -->`. RS-232C + TCP both populated (port 7142). Baud left null — source gives 5 options, no default. ID1/ID2/model-code/appendix-enum-tables unresolved (not in this extract).
