Summary

Sharp/NEC NP P502HL projector control spec covering RS-232C serial and wired/wireless LAN (TCP) control per the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands are binary hex frames with a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes). The spec enumerates power, mute, input switching, lens, picture/volume adjust, lamp/filter/carbon-savings information, status queries, and LAN/PIP/edge-blending configuration commands.

  baud_rate: 9600  # source lists 115200/38400/19200/9600/4800; pick per device config
  # baud_rate_options: [4800, 9600, 19200, 38400, 115200]

Traits

- powerable    # 015 POWER ON / 016 POWER OFF present
- routable     # 018 INPUT SW CHANGE present
- levelable    # 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST / 030-15 OTHER ADJUST present
- queryable    # many *REQUEST commands returning values present

Actions

# All command payloads verbatim from source (hex frames incl. checksum byte).
# Response frames carry <ID1> <ID2> (control ID + model code); command frames as
# documented do not include ID bytes. <CKS> = checksum = low 8 bits of sum of
# preceding bytes. Unparameterized commands show the full literal frame.

Notes

  • Source manual: BDT140013 Revision 7.1.
  • All commands are binary hex frames. Final byte is the checksum (CKS) = low-order 8 bits of the sum of all preceding bytes. Example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → checksum 03h.
  • Command frames in this manual do NOT include ID1 (control ID) / ID2 (model code); those appear only in response frames (<ID1> <ID2>). Implementer must substitute the device's configured control ID and model code when parsing responses.
  • Error responses use prefix A?h (high nibble A) with ERR1/ERR2 codes per source §2.4.
  • Several value tables (input terminal, aspect, eco mode, base model type, sub-input) are referenced as the "Supplementary Information by Command" appendix, which is not present in the refined source document.
  • Baud rate is selectable from {4800, 9600, 19200, 38400, 115200}; 9600 is recorded as a representative default but the source does not designate a single default.
  • Lens continuous drive (7Fh/81h in 053) must be followed by 00h to stop.
