Summary

Sharp/NEC V984Q Avt3 projector control spec covering RS-232C serial and TCP/IP (wired/wireless LAN) control via binary framed hex commands on TCP port 7142. Includes power, input switching, mute, lens, picture/volume adjust, status queries, and PIP/edge blending controls.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 as supported values; default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; source mentions RTS/CTS pins but specifies full-duplex communication mode only
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable  # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable  # inferred: many request commands (009, 037, 078, 097, 305) return state
  - levelable  # inferred: 030-1 PICTURE ADJUST, 030-2 VOLUME ADJUST present
  - routable  # inferred: 018 INPUT SW CHANGE switches input terminal

Actions

# Frame format: command bytes are literal hex; <ID1>=control ID, <ID2>=model code,
# <CKS>=checksum (low byte of sum of all preceding bytes).
# Response frames use 20h/21h/22h/23h prefix; error responses use A0h/A1h/A2h/A3h.

  - command: "016. POWER OFF"
    note: "During power-off (including cooling time), no other command can be accepted."
  - command: "053. LENS CONTROL"
    note: "After sending 7Fh/+continuous or 81h/-continuous, must send 00h to stop lens drive."
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing requirements beyond command-level acceptance notes above.

Notes

  • Binary framed protocol. All command/response frames use hex byte notation with h suffix.
  • Response prefixes: 20h/21h/22h/23h = success response (varies by command class); A0h/A1h/A2h/A3h = error response.
  • Common parameters in every frame: <ID1> = control ID set on projector; <ID2> = model code (model-specific, not in source); <CKS> = checksum (low-order byte of sum of all preceding bytes).
  • Checksum example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → checksum = 03h.
  • Usage-time fields (lamp, filter) update at one-minute intervals though reported in one-second units.
  • Lamp remaining life (%) returns negative value if replacement deadline exceeded.
  • Signal list number returned is 1 less than practical value (add 1 to obtain actual).
  • Many DATA values reference an "Appendix — Supplementary Information by Command" not present in this excerpt.

Known Gaps

- "firmware version compatibility not stated in source"
- "model code (ID2) value not stated for this specific model"
- "flow control not stated; source mentions RTS/CTS pins but specifies full-duplex communication mode only"
- "exact enum values referenced in Appendix, not in this excerpt"
- "source describes no unsolicited notifications / push events."
- "source describes no explicit multi-step sequences."
- "source contains no explicit safety warnings, interlock procedures,"
- "ID2 model code value for V984Q Avt3 not stated in source"
- "Appendix \"Supplementary Information by Command\" not included — exact enum values for input terminal, aspect, eco mode, sub input, base model type are missing"
- "default baud rate not stated (source lists 5 supported values)"
- "flow control scheme not explicitly stated"
- "firmware version compatibility not stated"
