Summary

Sharp/NEC projector with RS-232C serial control and TCP/IP LAN control (port 7142). Binary command protocol using hex-byte frames with checksum. Spec covers power, input switching, mutes, picture/volume/aspect adjustment, lens control, lens memory, status queries, eco mode, PIP/PbP, edge blending, and information requests. Source: BDT140013 Rev 7.1 Projector Control Command Reference Manual.

Macros

# UNRESOLVED: source documents no named multi-step sequences.

Safety

confirmation_required_for:
  - power_off
  - shutter_close
interlocks:
  - "Power ON: while command executing, no other command accepted."
  - "Power OFF: during power-off incl. cooling time, no other command accepted."
  - "Lens control: after sending 7Fh (plus-continuous) or 81h (minus-continuous) must send 00h to stop."
# UNRESOLVED: no explicit safety interlock procedures (e.g. lamp-door, high-voltage) described in refined source.

Notes

  • Binary protocol: frames in hex bytes; checksum (CKS) = low byte of sum of all preceding bytes.
  • Frame format per source §2.1: 20h 88h <ID1> <ID2> 0Ch <DATA01>...<DATA12> <CKS>. ID1 = control ID set on projector; ID2 = model code (varies by model).
  • Serial: RS-232C, cross cable, D-SUB 9P. Baud switchable 4800/9600/19200/38400/115200; default not stated in source — 9600 selected in spec as conservative default, UNRESOLVED true default.
  • LAN: wired 10/100 Auto or optional wireless LAN unit; TCP port 7142 for command transport.
  • Pin assignments documented (PC CONTROL D-SUB 9P and LAN RJ-45).
  • Information updates are minute-granular even when queryable in one-second units (lamp/filter usage).
  • Lamp remaining life (%) returned as negative value past replacement deadline.

Spec done. 53 actions cover every command row in source §2. Binary hex payloads copied verbatim; parameterized commands show variable part as `<DATAxx>`. Gaps marked `UNRESOLVED` (baud default, Appendix values, ID1/ID2, flow control, firmware).

## Known Gaps

```yaml
- "model-specific firmware version compatibility not stated. Input terminal numeric values referenced to an \"Appendix: Supplementary Information by Command\" not present in the refined source."
- "flow control not stated in source (RS-232 RTS/CTS pins wired but mode not specified)"
- "source documents no unsolicited notifications - all responses are command-acknowledgement only."
- "source documents no named multi-step sequences."
- "no explicit safety interlock procedures (e.g. lamp-door, high-voltage) described in refined source."
- "default baud rate not stated."
- "ID1 control ID and ID2 model code values not given for this model."
- "Appendix \"Supplementary Information by Command\" not present in refined source — input terminal values, eco-mode values, sub-input values, base-model-type values, aspect values cannot be enumerated."
- "flow_control (RTS/CTS) mode not specified despite RTS/CTS pins being wired."
- "firmware version compatibility not stated."
```
