Summary

Projector control spec for the Sharp/NEC Pn P506, based on the "Projector Control Command Reference Manual" (BDT140013 Revision 7.1). The device supports control over both RS-232C serial and TCP/IP (wired/wireless LAN) using a binary frame protocol with hex opcodes and a trailing checksum byte. This spec enumerates the full command catalogue (power, input switching, mutes, picture/volume/aspect adjust, lens control and memory, status queries, eco mode, PIP/PbP, edge blending, audio select, and information requests).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands."
serial:
  baud_rate: 115200  # source lists selectable rates 115200/38400/19200/9600/4800 bps; 115200 shown as first/highest option
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Communication mode: Full duplex" but does not specify flow control
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: POWER ON (015) / POWER OFF (016) commands present
  - queryable      # inferred: many status request commands present (009, 037, 060, 078, 084, 097, 305)
  - levelable      # inferred: PICTURE/VOLUME/LAMP adjust commands present (030-1, 030-2, 030-15)
  - routable       # inferred: INPUT SW CHANGE (018) and audio select (319-10) present

Actions

# Command frame format (hex): <Header> <ID1> <ID2> <LEN> <DATA...> <CKS>
# CKS (checksum) = low-order byte of the sum of all preceding bytes.
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# Each action below shows the literal command payload verbatim from the source.
# CKS in parameterized templates is computed at runtime.

# Source notes relevant operational constraints (not safety interlocks per se):
# - POWER ON (015): while powering on, no other command accepted.
# - POWER OFF (016): during power-off incl. cooling time, no other command accepted.
# - 009 ERROR STATUS includes interlock switch open bit (DATA09 Bit1) and cover/lens errors.
# UNRESOLVED: no explicit safety interlock procedures or power-on sequencing requirements stated.

Notes

  • Binary frame protocol: <Header> <ID1> <ID2> <LEN> <DATA...> <CKS>. Header byte encodes message category: 0xh = info/read, 1xh/2xh/3xh = write variants; response frames prefix with 2xh (success) or Axh (error) mirroring the command's low nibble.
  • Checksum (CKS): low-order one byte of the sum of all preceding bytes. Documented example: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • ID1 = control ID set on the projector; ID2 = model code (varies by model) — both must be filled per device at runtime.
  • Serial config selectable rates: 115200 / 38400 / 19200 / 9600 / 4800 bps; 8N1; full duplex. Baud shown as 115200 (first listed option) — configure to match projector setting.
  • Lamp/filter usage times update at 1-minute intervals despite 1-second resolution.
  • Remote key code command (050) sends virtual remote keys; useful for UI navigation (UP/DOWN/ENTER/EXIT/MENU).
  • The source is a shared NEC/Sharp projector reference manual (BDT140013 Rev 7.1); exact Pn P506 feature support should be confirmed against the device.

Spec done. 53 commands, all verbatim. TCP port 7142 + serial 8N1 multi-baud. No fabricated values — gaps marked UNRESOLVED (appendix enums, ID2 model code, firmware, flow control).

Known Gaps

- "source manual is a generic projector reference (BDT140013 Rev 7.1) describing projector features (lens, lamp, shutter); it does not explicitly name the Pn P506 model or confirm which commands that model supports. Appendix \"Supplementary Information by Command\" referenced for input terminal / aspect / eco mode / base model type enum values was not included in the refined source text, so several enum value tables are incomplete."
- "source states \"Communication mode: Full duplex\" but does not specify flow control"
- "source describes only request/response; no unsolicited notifications documented."
- "no multi-step sequences described explicitly in source."
- "no explicit safety interlock procedures or power-on sequencing requirements stated."
- "Appendix \"Supplementary Information by Command\" (input terminal values, aspect values, eco mode values, base model type values, sub input values) was not present in the refined source text, so several enum tables are incomplete."
- "firmware version compatibility not stated in source."
- "wireless LAN unit details deferred to separate operation manual."
- "exact Pn P506 model confirmation and ID2 model code not stated in this manual."
