Summary

Sharp/NEC V864Q Mpi is an MPI-series professional projector controllable over RS-232C (PC CONTROL D-SUB 9P) and wired/wireless LAN. This spec covers the binary-framed command protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands use a hex-byte frame 20h 88h <ID1> <ID2> <LEN> <DATA> <CKS> with a one-byte additive checksum.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # stated in source: "Use TCP port number 7142"
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 bps; high value shown
  # NOTE: baud rate is selectable; other valid rates: 38400, 19200, 9600, 4800
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source
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
  - routable     # inferred: INPUT SW CHANGE (018) routing command present
  - levelable    # inferred: PICTURE/VOLUME/LAMP adjust commands present

Actions

# Binary protocol. Frame: <hdr> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID, ID2 = model code (both set on projector, values not in source).
# CKS = additive checksum (low byte of sum of all preceding bytes).
# Literal payloads verbatim from source; parameterized actions show variable parts.

Notes

  • Protocol: RS-232C-compliant serial + TCP/IP on port 7142 (both wired and optional wireless LAN units).
  • Checksum: Additive — sum all bytes preceding CKS, use low-order one byte. Example: 20h+81h+01h+60h+01h+00h=103h → CKS=03h.
  • Frame layout: <header> <ID1> <ID2> <LEN> <DATA??...> <CKS>. Header byte groups: 00h=read-only queries (ack A0h), 01h/02h=actions (ack 21h/22h, error A1h/A2h), 03h=parameterized ops (ack 23h, error A3h).
  • ID1 (control ID): set on projector; ID2 (model code): varies by model. Both values not stated in this source.
  • Lamp/filter usage time: returned in seconds; displayed info updated at 1-minute intervals.
  • Two-lamp models: DATA01=01h (Lamp 2) effective only on two-lamp projector models.
