Sharp/NEC M321 Pt Control Spec

Summary

Sharp/NEC M321 Pt projector control spec (manual BDT140013 Rev 7.1). Binary hex frame protocol over RS-232C serial or TCP/IP LAN (port 7142). Covers power, input switching, mute, picture/volume/aspect/gain adjust, lens control & memory, status queries, eco mode, edge blending, PIP/PbP, and audio select.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # source: "Use TCP port number 7142 for sending and receiving commands"
serial:
  baud_rate: 115200  # configurable: source lists 115200/38400/19200/9600/4800 bps supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow control; RTS/CTS pins wired in pinout
auth:
  type: none  # inferred: no auth/login procedure described in source

Traits

traits:
  - powerable   # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable   # inferred: extensive status/info request commands
  - levelable   # inferred: volume, picture (brightness/contrast/etc.), lamp adjust commands
  - routable    # inferred: 018 INPUT SW CHANGE present

Actions

# All command payloads are binary hex frames (literal from source, verbatim).
# Frame layout: <CMD_CLASS> <OPCODE> <ID1> <ID2> <LEN> [<DATA...>] <CKS>
# ID1=control ID, ID2=model code (00h 00h = broadcast in examples).
# CKS = checksum: low-order byte of sum of all preceding bytes.
# Power-on/off reject all other commands during transition (incl. cooling).

Notes

• Manual revision: BDT140013 Rev 7.1. D-SUB 9P PC CONTROL port, RJ-45 LAN port.
• Frame structure: <class> <opcode> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1=control ID, ID2=model code (00h 00h = broadcast). Checksum = low byte of sum of all preceding bytes.
• Class bytes: 00h/01h/02h/03h command types; success responses prefix 20h/21h/22h/23h; error responses prefix A0h/A1h/A2h/A3h.
• Timing: lamp/filter usage updates at 1-minute intervals despite 1-second resolution.
• Cooling lockout: during POWER OFF cooling, no commands accepted.
• Lens continuous drive: after 7Fh/81h continuous-drive DATA02, send 00h to stop; same command can redirect mid-drive without stop.
• Wireless LAN: supported via optional wireless LAN unit (see separate operation manual).
• Appendix missing from this source: input terminal values, aspect values, eco/light/lamp mode values, base model type values, sub input setting values — all referenced as "Supplementary Information by Command" but not present in refined excerpt.

Spec done. 53 actions enumerated (all source rows). Both serial+TCP transports. Hex payloads verbatim. Appendix-listed value sets marked UNRESOLVED.

- "source states \"Full duplex\" communication mode but does not specify flow control; RTS/CTS pins wired in pinout"
- "not in this source).\""
- "source documents no unsolicited notifications / push events. Protocol is request/response only."
- "source documents no explicit multi-step sequences."
- "source contains no explicit safety warnings, hardware interlock procedures,"
- "firmware version compatibility not stated in source"
- "input terminal value list referenced but not in source"
