Summary
Sharp/NEC projector control spec. RS-232C serial + wired/wireless LAN (TCP). Binary protocol, hex bytes, frame = header + ID1 + ID2 + LEN + DATA + checksum. Source = BDT140013 Rev 7.1 (Projector Control Command Reference). Covers power, input switch, mute, picture/volume/aspect adjust, lens control + memory, status queries, network/eco/edge-blend config.

Notes
Binary protocol. Frame layout: [Header] [ID1] [ID2] [LEN] [DATA...] [CKS]. Header byte encodes direction + cmd group: 0xh=request/get, 2xh=ack-success, 3xh=set-success-extended, Axh=error response. ID1=control ID set on projector; ID2=model code (varies by model). Checksum = low byte of sum of all preceding bytes.
Power + cooling lock commands — do not flood during transitions. Lamp/filter usage updated at 1-minute intervals though stored in 1-second units. Lamp remaining life goes negative past replacement deadline.
{CKS} placeholders = computed checksum byte (must be calculated by implementer per formula above). {ID1}/{ID2} = device-set identifiers, not fixed.
