Summary

Sharp/NEC PN-HS501 large-format display/projector. Binary hex control protocol over RS-232C serial and TCP/IP LAN (port 7142). Frames carry command opcode, data bytes, and trailing low-byte checksum. Manual revision BDT140013 Rev 7.1.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: null  # UNRESOLVED: source lists multiple (115200/38400/19200/9600/4800) - no single value stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow_control not stated (RTS/CTS pins wired per pin table, mode unstated)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: POWER ON / POWER OFF commands present
  - queryable      # inferred: many *REQUEST queries returning state
  - levelable      # inferred: PICTURE ADJUST / VOLUME ADJUST continuous params
  - routable       # inferred: INPUT SW CHANGE / AUDIO SELECT SET routing commands

# CKS = low byte of sum of all preceding bytes. CKS shown verbatim from source.
# For LAN/TCP frames, <ID1> <ID2> are inserted after byte[1] in responses; command
# payloads below are the literal serial-form bytes from the source. Developers must
# recompute CKS when DATA placeholder is filled.

Notes

  • All command bytes are hexadecimal, transmitted as raw bytes (not ASCII hex text).
  • Checksum = low 8 bits of sum of all preceding bytes. Example: 20h 81h 01h 60h 01h 00h → 103h → CKS=03h.
  • Responses use leading nibble to indicate class: 2xh/3xh = success reply mirroring command class; Axh = error reply (<ERR1> <ERR2> follow). ERR1/ERR2 codes documented in §2.4 (e.g. 00h/00h unrecognized, 02h/0Dh power off, 02h/0Fh no authority).
  • For LAN/TCP, the same serial-style payload is used with <ID1> (control ID) and <ID2> (model code) inserted in responses; command payloads match serial form.
  • Picture/Sound/Onscreen mute auto-clear on input/video switch (and volume adjust for sound mute).
  • Lamp/filter usage updates at one-minute intervals even though stored in one-second units.

Known Gaps

- "source is generic \"Projector Control Command Reference Manual\" — model PN-HS501 supplied by operator, not stated verbatim in doc body. Firmware compat, voltage/power specs, exact full enumeration of LENS CONTROL DATA01 targets (only 06h Periphery Focus shown) not in source."
- "source lists multiple (115200/38400/19200/9600/4800) - no single value stated"
- "flow_control not stated (RTS/CTS pins wired per pin table, mode unstated)"
- "appendix not in source."
- "appendix not in source)."
- "other target values (zoom/focus/shift) not enumerated in source.\""
- "enumeration incomplete in source."
- "full response schema for queries 037, 037-3, 037-4, 037-6, 053-7, 060-1, 078-1/2/3, 084, 097-*, 305-* are documented in source but only the major observable states are enumerated above as feedbacks."
- "none documented."
- "source documents no multi-step command sequences."
- "no explicit confirmation/interlock procedures documented in source."
- "(1) Appendix \"Supplementary Information by Command\" referenced for input terminal, aspect, eco mode, sub input, base model type values — not present in refined source. (2) Full DATA01 enumeration for LENS CONTROL (053) missing — only 06h Periphery Focus shown. (3) Model PN-HS501 not named verbatim in doc body — sourced from operator. (4) Baud rate multiple options, no default stated. (5) Flow control mode unstated despite RTS/CTS wiring."
