Sharp/NEC Ma431 Mpi4E Control Spec

Summary

Sharp/NEC projector (Ma431 Mpi4E) control spec covering RS-232C serial and wired/wireless LAN (TCP) interfaces. Source is the Projector Control Command Reference Manual (BDT140013 Rev 7.1), documenting 53 binary commands (power, input switch, mutes, lens control, status queries, edge blending, PIP/PbP, network settings). Binary frames carry a trailing checksum byte.

Transport

protocols:
  - tcp
  - serial
# Source documents both serial (PC CONTROL port) and LAN (wired/wireless) connections.
addressing:
  port: 7142
serial:
  baud_rate: null  # UNRESOLVED: multiple rates supported - 115200/38400/19200/9600/4800 bps; source does not state a default
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: communication mode stated as "Full duplex"; flow_control value not explicitly stated
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON (015) / POWER OFF (016) commands present
  - queryable       # inferred: many *REQUEST commands returning state present
  - levelable       # inferred: PICTURE ADJUST / VOLUME ADJUST / OTHER ADJUST present
  - routable        # inferred: INPUT SW CHANGE (018) switches input terminal

Notes

Binary frame protocol. Commands/responses use hex notation (NNh). Frame structure: header byte (00h-03h command class / 20h-23h success response / A0h-A3h error response) followed by command code, <ID1> (control ID), <ID2> (model code), <LEN> (data length), data bytes, and <CKS> (checksum).

Checksum (CKS) calculation: add all preceding bytes; use the low-order one byte (8 bits) of the result. Worked example from source: 20h 81h 01h 60h 01h 00h → 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.

ID2 (model code) varies by model in use — not stated for Ma431 Mpi4E in this source.

Multiple baud rates supported (115200/38400/19200/9600/4800 bps); source does not state a default. TCP port 7142 is fixed for LAN command send/receive. Full-duplex serial.

Several value enumerations are referenced as an external Appendix ("Supplementary Information by Command") that is NOT included in this refined source: input terminal codes, aspect values, eco mode values, sub-input values, base model type codes. These are marked in their respective actions/variables.

Spec done. 53 actions = full command list (009→319-10), each with verbatim hex payload. Serial+TCP both in source so both emitted. Baud = `null` UNRESOLVED (5 rates, no default stated). Appendix value tables absent → marked UNRESOLVED per action. Want ingest next?
