Summary
The Sharp/NEC LED FC015I is a projector controllable via RS-232C serial (D-SUB 9P PC CONTROL port) and wired/wireless LAN. This spec covers the binary command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mute, lens, picture/volume adjustment, and status query commands.

Traits
traits:
- powerable # inferred: 015 POWER ON / 016 POWER OFF commands present
- routable # inferred: 018 INPUT SW CHANGE / 319-10 AUDIO SELECT SET commands present
- queryable # inferred: many status request commands present
- levelable # inferred: 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST present
Actions
# Checksum (CKS) rule: sum all preceding bytes, take low-order one byte.
# Framing: command first byte encodes direction+class (02h/03h set, 00h get).

Power commands block all other commands during execution: 015 POWER ON accepts
no other command while turning on; 016 POWER OFF accepts none during power-off
incl. cooling time. 018 INPUT SW CHANGE may return FFh (no switch made) if no
signal present. Error code 02h 0Dh = "command cannot be accepted because the
power is off." Error code 02h 0Fh = "no authority necessary for the operation."

# power-on sequencing requirements, or voltage/current specs. Interlock
# switch open status is reported in 009 ERROR STATUS REQUEST DATA09 Bit1 but
# no control-side interlock procedure is documented.
Notes
- Manual revision: BDT140013 Rev 7.1.
- Serial cable: cross cable to PC CONTROL port (D-SUB 9P). Pin assignment: 2=RxD, 3=TxD, 5=GND, 7=RTS, 8=CTS (crossed to external device).
- LAN: RJ-45 wired (10/100 Mbps auto) or wireless LAN unit. TCP port 7142.
- Binary framing: commands/responses expressed in hex. Common params: ID1 (control ID), ID2 (model code), CKS (checksum = low byte of sum of all preceding bytes), LEN (data length), ERR1/ERR2 (response error codes).
- Response prefixes:
2xh/2xhecho success with optional data;Axhprefix = error response carrying ERR1/ERR2. - Usage times update at one-minute intervals despite one-second resolution.
- Lamp remaining life returns negative percent if replacement deadline exceeded.
Spec ready. 53 actions, all hex payloads verbatim. Gaps marked UNRESOLVED (Appendix value maps, firmware, wireless LAN, ID2 model code).

## Known Gaps
```yaml
- "firmware version compatibility not stated in source. Input terminal value map, aspect value map, eco-mode value map, base model type value map, and sub-input value map are referenced as \"Appendix: Supplementary Information by Command\" but that appendix is not present in the refined source. Wireless LAN communication conditions not detailed (deferred to wireless LAN unit manual)."
- "eco mode value enum in Appendix not present in source"
- "aspect value enum in Appendix not present in source"
- "no event/notification mechanism stated in source."
- "populate if source contains macro sequences; none found."
- "source contains no explicit safety interlock procedures,"
- "Appendix \"Supplementary Information by Command\" referenced for input terminal values, aspect values, eco mode values, base model type values, and sub-input values — not present in refined source. Wireless LAN unit specs deferred to separate operation manual. ID2 model code value not stated."
