Summary

Sharp/NEC large-format LED projector (165 in) controlled via the "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). Control interface is a binary hex-byte protocol with a trailing checksum byte, carried over RS-232C serial or wired/wireless LAN (TCP). Covers power, input switching, mutes, picture/volume/aspect/lamp adjust, lens shift/zoom/focus/memory, shutter, freeze, eco mode, edge blending, PIP/PbP, and a broad set of status/error/lamp/filter/information queries.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists 115200/38400/19200/9600/4800 as selectable; 9600 chosen as common default - device-configurable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not explicitly stated; full-duplex communication mode noted
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON (015) / POWER OFF (016)
  - routable        # inferred: INPUT SW CHANGE (018), AUDIO SELECT SET (319-10)
  - queryable       # inferred: many *REQUEST commands
  - levelable       # inferred: PICTURE/VOLUME/LAMP ADJUST (030-*), LENS CONTROL (053*)

Actions

# All command/response hex bytes are VERBATIM from source (BDT140013 Rev 7.1).
# Framing convention: every command begins with a lead byte; responses echo with
# bit 5/7 of lead set (20h/22h/23h -> ack frames; A0h/A1h/A2h/A3h -> error frames).
# ID1 = Control ID, ID2 = model code, CKS = checksum (low byte of sum of preceding bytes).

Notes

  • Source: "Projector Control Command Reference Manual", BDT140013 Revision 7.1 (Sharp/NEC). All hex payloads copied verbatim.
  • Checksum (CKS): sum all preceding bytes, take low-order one byte. Worked source example: 20h + 81h + 01h + 60h + 01h + 00h = 103h -> CKS = 03h.
  • Framing: commands use lead bytes 00h/01h/02h/03h; success acks use 20h/21h/22h/23h (same low nibble); error acks use A0h/A1h/A2h/A3h.
  • ID1 = Control ID configured on projector; ID2 = model code (model-dependent).
  • Baud rate is selectable among 115200/38400/19200/9600/4800; 9600 recorded as the conservative default — verify against on-device setting.
  • Lamp/filter usage times returned in seconds, updated at one-minute intervals.
  • Two-lamp projector features (Lamp 2) only apply to two-lamp models; this LED unit is single-light-engine — confirm applicability.

Spec built. 53 commands enumerated verbatim. Serial+TCP port 7142. Binary hex + checksum. Gaps marked UNRESOLVED (ID2 model code, Appendix value tables, firmware).
