Sharp/NEC X464Unv 3 Control Spec

Summary

Sharp/NEC display/projector control spec covering the hex-byte control protocol described in the vendor Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device exposes both an RS-232C serial interface and a TCP/IP (LAN) interface on port 7142, sharing one command set. Commands are framed in hexadecimal bytes with a trailing checksum byte (low-order 8 bits of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 9600  # source lists 115200/38400/19200/9600/4800 as selectable; 9600 is one of the documented rates, not a single default
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not name a flow-control scheme
addressing:
  port: 7142
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 (009, 037, 078-*, 097-*, 305-*)
  - levelable    # inferred: PICTURE ADJUST (030-1), VOLUME ADJUST (030-2), LAMP/LIGHT ADJUST (030-15), LENS CONTROL (053/053-2)
  - routable     # inferred: INPUT SW CHANGE (018) and AUDIO SELECT SET (319-10) select signal/audio routing

Actions

# All command bytes are VERBATIM from the source. ID1 (control ID) and ID2 (model
# code) are runtime-supplied framing bytes per the projector setting; CKS is the
# computed low-order-8-bits checksum of all preceding bytes (see §2.2).
# Commands listed without <ID1> <ID2> in the source are the literal request bytes;
# the framed request prepends the leading byte (02h/03h/00h/01h) shown.

Variables

# No settable continuous variables beyond the parameterized actions above; set/state
# values are obtained via the *REQUEST query actions. Nothing to enumerate here.

Events

# Source describes request/response only. No unsolicited notifications documented.
# UNRESOLVED: device may push asynchronous error/interlock events, but the source
# does not document any.

Macros

# No multi-step sequences explicitly described in the source.

Safety

confirmation_required_for: []
interlocks: []
# Source notes operational interlocks in command prose but no formal interlock table:
# - 015 POWER ON: no other command accepted during power-on sequence.
# - 016 POWER OFF: no other command accepted during power-off (incl. cooling time).
# - 020 PICTURE MUTE / 022 SOUND MUTE / 024 ONSCREEN MUTE: cleared on input/video-signal switch.
# - 053 LENS CONTROL: continuous drive (7Fh/81h) must be stopped by sending 00h.
# - 053-2 LENS CONTROL 2 with DATA01=FFh (Stop): adjustment mode/value are ignored.
# UNRESOLVED: source contains no explicit safety warnings, cover-interlock procedures,
# or formal power-on sequencing requirements. The 009 ERROR STATUS REQUEST bitfields
# (cover error, fan error, temperature error, interlock switch open, etc.) are the
# closest thing to safety telemetry and are surfaced as a query, not an interlock spec.

Notes

• Source document is the generic Sharp/NEC Projector Control Command Reference Manual (document number BDT140013, Revision 7.1). It documents a Sharp/NEC projector protocol family and is being applied here to the X464Unv 3; per-command applicability to a large-format display is not asserted by the source.
• Every command/response is expressed as a hexadecimal byte sequence. Frames embed <ID1> (control ID set on the projector) and <ID2> (model code). <CKS> is the low-order 8 bits of the sum of all preceding bytes. The source's worked example: 20h 81h 01h 60h 01h 00h <CKS> → sum 103h → CKS = 03h.
• The serial line supports 115200 / 38400 / 19200 / 9600 / 4800 bps (selectable in software); 8 data bits, no parity, 1 stop bit, full duplex. The spec records 9600 as the canonical default because the source does not name a single default rate — implementers should treat baud as configurable.
• LAN transport is wired IEEE 802.3 / 802.3u (10/100 auto) plus an optional wireless LAN unit, all carrying the same command set on TCP port 7142.
• Many command DATA enums (input terminal, aspect, base model type, eco mode, sub input) are deferred by the source to an Appendix titled "Supplementary Information by Command" that is not present in this refined source text. Those fields are marked UNRESOLVED in their params descriptions.
