Summary

The Sharp/NEC Pn Hy551 is a projector controllable via RS-232C serial (PC CONTROL D-SUB 9P) and TCP/IP LAN (wired RJ-45 or wireless). This spec covers the binary command protocol described in BDT140013 Revision 7.1, including power, input, mute, lens, picture, eco, edge-blending, PIP, and status-query commands. Commands are framed with ID1 (control ID), ID2 (model code), a checksum byte, and command-type prefixes that mirror in the response (success: command byte + 20h; error: command byte + A0h).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists 115200/38400/19200/9600/4800 bps as selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow control method

Traits

traits:
  - powerable       # inferred from POWER ON / POWER OFF commands
  - queryable       # inferred from many status query commands
  - levelable       # inferred from VOLUME / PICTURE / LAMP ADJUST commands
  - routable        # inferred from INPUT SW CHANGE / AUDIO SELECT SET commands

Events

# Source describes no unsolicited notifications. All responses are solicited by commands.
# UNRESOLVED: source does not document push/event behaviour; none populated.

Macros

# Source describes no multi-step command sequences.
# UNRESOLVED: none populated.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    note: "While turning on power, no other command accepted."
  - command: power_off
    note: "While turning off power (including cooling time), no other command accepted."
  - command: lens_control
    note: "After sending 7Fh/81h continuous drive, must send 00h to stop lens."
# UNRESOLVED: source describes no explicit safety interlock procedures, power-on sequencing requirements, or voltage/current protection thresholds. Only operational command-acceptance interlocks noted above.

Notes

  • Binary framing: every command/response is hex. Common parameters ID1 (control ID, projector-set), ID2 (model code, varies by model), CKS (checksum = low byte of sum of all preceding bytes), LEN (data length of trailing DATA?? bytes).
  • Response convention: success response echoes the command-type byte (00h/01h/02h/03h) plus 20h → 20h/21h/22h/23h. Error response uses the command-type byte plus A0h → A0h/A1h/A2h/A3h, with ERR1/ERR2 codes per the error-code list (00h/00h=unrecognized, 00h/01h=not supported by model, 01h/00h=invalid value, 02h/0Dh=power off, 02h/0Fh=no authority, etc.).
  • Usage-time fields (lamp, filter) update at one-minute intervals despite being readable in one-second units.
  • Picture/sound/onscreen mute auto-clear on input-terminal switch or video-signal switch; sound mute also clears on volume adjustment.
  • LENS CONTROL REQUEST returns target-specific upper/lower/current bounds; LENS CONTROL 2 supports FFh "Stop" without referencing mode/value.

matched_actions: 53

summary: "All 53 spec actions matched verbatim against source command reference; transport parameters verified; complete bidirectional coverage. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "input-terminal value table, aspect value table, eco-mode value table, sub-input setting values, base-model-type value table, and key-code→input mappings are referenced as \"see Appendix 'Supplementary Information by Command'\" which is not in the source text."
- "source states \"Full duplex\" communication mode but does not specify flow control method"
- "not in source).\""
- "full target table not enumerated in this command's section.\""
- "not enumerated in this command's section.\""
- "source does not document push/event behaviour; none populated."
- "none populated."
- "source describes no explicit safety interlock procedures, power-on sequencing requirements, or voltage/current protection thresholds. Only operational command-acceptance interlocks noted above."
- "Appendix \"Supplementary Information by Command\" is referenced throughout (input terminal codes, aspect values, eco-mode values, sub-input settings, base-model-type codes, display signal types) but is NOT present in the source text. These value tables must be supplied before the spec is verifiable end-to-end."
- "ID1 control ID default value and ID2 model code value for Pn Hy551 not stated in source."
- "serial flow-control method (RTS/CTS, XON/XOFF) not stated; pinout exposes RTS/CTS lines but the spec only says \"Full duplex\"."
- "firmware version compatibility not stated in source."
