Summary

Sharp/NEC NP PX803UL WH large-venue projector. Binary control protocol over RS-232C serial (PC CONTROL D-SUB 9P) and TCP/IP LAN (port 7142). Manual BDT140013 Rev 7.1 enumerates 53 distinct hex-encoded commands covering power, input switching, mute, picture/volume/aspect/gain adjustment, lens control and memory, information/status queries, remote key emulation, freeze, shutter, eco mode, edge blending, PIP/PbP, and audio select.

Events

# No unsolicited notification frames documented in source. All responses are request/response.
# UNRESOLVED: device may push status changes, but source documents no event channel.

Macros

# Source documents no explicit multi-step sequences.

Safety

confirmation_required_for: []
interlocks:
  - "Power-on sequence locks out all other commands until complete (015 POWER ON)."
  - "Power-off / cooling sequence locks out all other commands until complete (016 POWER OFF)."
  - "Lens control: continuous-drive (7Fh / 81h) must be stopped by sending DATA02=00h."
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures, or
# power-on sequencing requirements beyond the per-command lockout notes above.

Notes

  • Command/response frames use hex notation; first byte identifies direction/type: 0x-prefixed opcodes are host→projector commands, 2xh success responses, Axh error responses.
  • Checksum (CKS) = low byte of sum of all preceding bytes. Example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
  • ID1 = projector Control ID (configurable). ID2 = model code, varies by model — value for NP PX803UL WH not stated in this excerpt.
  • LAN transport: TCP port 7142 (stated explicitly). 10/100 Mbps auto-sensing, IEEE 802.3 / 802.3u.
  • Serial: baud selectable among 115200 / 38400 / 19200 / 9600 / 4800 bps; 8N1, full duplex. Highest rate listed in baud_rate field — operator must match projector setting.
  • "Supplementary Information by Command" appendix (referenced for input terminal, eco-mode, sub-input, base-model-type value tables) is not present in this refined excerpt.

Spec emitted: 53 actions (full source coverage), dual transport, all literal hex payloads verbatim. UNRESOLVED markers for missing appendix value tables + ID2 model code + firmware.
