Summary

Sharp/NEC V984Q Mpi large-format display / projector controlled via RS-232C serial (PC CONTROL D-SUB 9P) or wired/wireless LAN using TCP port 7142. Binary framed protocol: each command is a hex byte sequence terminated by a checksum byte (low-order 8 bits of the sum of all preceding bytes). Manual reference BDT140013 Rev 7.1 enumerates 53 distinct commands covering power, input switching, mutes, picture/volume/aspect adjustment, lens control & memory, status queries, eco mode, PIP/PbP, edge blending, and audio select.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: "115200, 38400, 19200, 9600, 4800"  # source lists all five as supported
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated in source (full-duplex mode stated, not flow control)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many status REQUEST commands return values
  - routable     # inferred: INPUT SW CHANGE selects input terminal
  - levelable    # inferred: VOLUME ADJUST, PICTURE ADJUST (brightness/contrast/etc.), LENS CONTROL

Actions

# All command payloads are the literal hex byte sequences documented in the
# source, verbatim. <DATA??> = variable parameter byte(s); <CKS> = checksum
# (low-order 8 bits of the sum of all preceding bytes, including ID1/ID2 when
# present). Default framing uses ID1=00h (control ID 0), ID2=model code.

Safety

confirmation_required_for: []
interlocks:
  - command: "015. POWER ON"
    behavior: "While power-on is in progress, no other command is accepted."
    source: "3.2"
  - command: "016. POWER OFF"
    behavior: "While power-off (including cooling time) is in progress, no other command is accepted."
    source: "3.3"
  - command: "053. LENS CONTROL"
    behavior: "After continuous-drive (7Fh/81h) a Stop (00h) must be sent to halt the lens."
    source: "3.22"
# UNRESOLVED: no explicit safety interlock procedures, power-on sequencing
# requirements, or personnel-safety warnings present in the refined source
# excerpt. Error code 02h 0Dh ("command cannot be accepted because the power
# is off") implies commands require power-on, but no formal interlock table.

Notes

  • Protocol framing: Each command is a hex byte sequence. Format: [type][cmd][ID1][ID2][LEN][DATA...][CKS]. ID1 = control ID (default 00h), ID2 = model code (varies by model — value for V984Q Mpi not in this excerpt). CKS = low-order 8 bits of the sum of all preceding bytes.
  • Response discrimination: success-response leading byte = command-type + 20h; error-response leading byte = command-type + A0h. Error responses carry <ERR1> <ERR2> codes (see source §2.4, 23 code combinations).
  • Two transport paths: RS-232C cross-cable on PC CONTROL (D-SUB 9P, pins 2/3/5/7/8 used), or LAN (wired RJ-45 or optional wireless LAN unit) on TCP port 7142. Both carry the same binary command set.
  • Baud rate: five rates supported (115200 / 38400 / 19200 / 9600 / 4800); source does not designate a default — must match the projector's configured setting.
  • Polling cadence: lamp/filter usage times are delivered in one-second units but updated internally at one-minute intervals.
  • Key-code list (command 050) maps 25 remote keys; DATA02 is 00h for every listed key.
  • Picture/volume mute auto-clears on input/video switch (and volume adjust clears sound mute).
