Summary

Sharp/NEC PA302W BK projector control spec. Covers both RS-232C serial (PC CONTROL D-SUB 9P, cross cable) and LAN (wired/wireless) control. Binary hex command protocol with checksummed frames.

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: none  # UNRESOLVED: flow control not stated in source; source states "Full duplex" communication mode only
addressing:
  port: 7142  # TCP port for command send/receive over LAN
auth:
  type: none  # inferred: no auth procedure in source

Traits

# - powerable    # inferred: POWER ON / POWER OFF commands present
# - queryable    # inferred: many *REQUEST commands returning state present
# - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST present

Actions

# Protocol framing: command frames are hex byte sequences. Common params:
#   ID1 = control ID, ID2 = model code, CKS = checksum (low byte of sum of all
#   preceding bytes). LEN = data length following LEN.
# Each action lists the literal command bytes (command template where parameterized).
# ACK/error response frame: A{x}h {cmd} <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>.

Events

# UNRESOLVED: source does not document any unsolicited notifications; all
# responses are replies to commands.

Macros

# UNRESOLVED: source does not describe explicit multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks:
  - "Power On (015): no other command accepted while power-on in progress."
  - "Power Off (016): no other command accepted during power-off incl. cooling time."
# UNRESOLVED: source contains no explicit safety warnings, interlock procedures,
# or power-on sequencing beyond the command-acceptance notes above.

Notes

  • Binary hex protocol: each command is a byte sequence. <ID1> = projector control ID, <ID2> = model code. Checksum (<CKS>) = low byte of sum of all preceding bytes (incl. command header).
  • Source is generic projector command reference (BDT140013 Rev 7.1); model name inferred from input metadata, not from document body.
  • Serial cable: D-SUB 9P cross cable. Pin 2/3 = RxD/TxD cross, pin 5 = GND, pin 7/8 = RTS/CTS cross.
  • LAN port: RJ-45 8-pin, 10/100 Mbps auto-switchable, IEEE 802.3 / 802.3u.
  • Many commands reference an "Appendix: Supplementary Information by Command" for value tables (input terminals, aspect values, eco mode values, sub-input values, base model types) — that appendix is NOT present in the source excerpt and corresponding value enumerations are left UNRESOLVED.

summary: "All 53 spec actions have verbatim hex command frames confirmed in source; transport port 7142 and baud rates confirmed; source catalogue exhausted by the spec. (12 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "model name \"PA302W BK\" inferred from input device name; source document is generic \"Projector Control Command Reference Manual\" (BDT140013 Rev 7.1) and does not name a specific model."
- "input terminal values (Appendix \"Supplementary Information by Command\") not present in source excerpt."
- "aspect values, eco mode values, sub-input values not present in source excerpt (referenced Appendix absent)."
- "flow control not stated in source; source states \"Full duplex\" communication mode only"
- "source does not separately document persistent settable variables"
- "source does not document any unsolicited notifications; all"
- "source does not describe explicit multi-step macro sequences."
- "source contains no explicit safety warnings, interlock procedures,"
- "firmware version not stated."
- "flow_control not stated in source."
- "control ID (ID1) and model code (ID2) per-device values not stated."
- "Appendix value tables (input terminal, aspect, eco mode, sub-input, base model type) absent from source excerpt."
