Summary

Sharp/NEC LED FE012I3 220 projector, controlled via RS-232C serial or TCP/IP LAN. Binary command protocol with hex-encoded frames; commands carry a trailing checksum byte computed as the low-order 8 bits of the sum of all preceding bytes. Manual covers power, mute, input switching, picture/volume/aspect/gain adjustment, lens control, lens memory, status queries, and LAN configuration.

Traits

traits:
  - powerable       # inferred from POWER ON / POWER OFF commands
  - queryable       # inferred from many status request commands
  - levelable       # inferred from PICTURE ADJUST / VOLUME ADJUST / LAMP ADJUST commands
  - routable        # inferred from INPUT SW CHANGE / AUDIO SELECT SET commands

Notes

  • Binary protocol: every frame is hex bytes. Response framing differs by command group — successful command echoes use prefix 2Xh (where X matches command's first nibble), error responses use prefix AXh, query replies use 2Xh with DATA.
  • Checksum (CKS) = low-order 8 bits of sum of all preceding bytes. Example: 20h 81h 01h 60h 01h 00h → sum=103h → CKS=03h.
  • Parameters ID1 (control ID set on projector) and ID2 (model code, model-dependent) are inserted into responses; commands sent to projector do not include them in the leading bytes shown.
  • LEN field = byte length of DATA part following LEN.
  • Error code pairs (ERR1, ERR2) listed in §2.4 — 00h/00h unrecognized command, 00h/01h unsupported by model, 01h/00h invalid value, 02h/0Dh power off, 02h/0Eh execution failed, etc.
  • Source supports both RS-232C (PC CONTROL D-SUB 9P, cross cable, pins 2/3/5/7/8 active) and TCP/IP (wired RJ-45 10/100 or optional wireless LAN unit). TCP port 7142.
  • Many commands reference an "Appendix — Supplementary Information by Command" for input terminal values, aspect values, eco mode values, sub-input values, base model types, and selection signal types; that appendix is not present in this refined excerpt.

Spec output above. 53 actions enumerated — matches all command list rows §2. Both serial + tcp transports (port 7142 verbatim). Baud options listed, default unresolved. Checksum rule documented. No invented values.

## Known Gaps

```yaml
- "firmware version compatibility not stated in source. Exact model-code (ID2) value not documented in this excerpt. Power/voltage specs not in scope of this control doc."
- "flow control not stated in source; \"Full duplex\" communication mode stated"
- "no events section populated from source."
- "no macros populated from source."
- "no explicit power-on sequencing procedure or interlock procedure stated beyond the above notes."
- "Appendix enumerations (input terminal values, aspect values, eco mode values, sub-input values, base model types, selection signal types) not in source excerpt."
- "model code (ID2) value for LED FE012I3 220 not stated in this excerpt."
- "default baud rate among the listed options (115200/38400/19200/9600/4800) not stated."
- "flow_control not stated (only \"Full duplex\" communication mode documented)."
- "firmware version compatibility not stated in source."
