Sharp/NEC NP PA653UL Control Spec

Summary

The Sharp/NEC NP PA653UL is a professional LCD projector controllable via an RS-232C serial port or a wired/wireless LAN (TCP port 7142). The device uses a binary frame protocol: each command is a sequence of hex bytes terminated by a one-byte checksum (low-order byte of the sum of all preceding bytes). This spec covers the full command catalogue documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1), including power, input switching, mute, picture/volume/lens adjustment, lens memory, status queries, eco mode, PIP/PbP, edge blending, and informational requests.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # TCP port for LAN command send/receive, stated in source
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # auto/configurable; all listed in source
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # full duplex stated; specific flow-control line usage (RTS/CTS pins wired) noted but mode not named
auth:
  type: none  # inferred: no auth/login procedure in source

Traits

traits:
  - powerable       # inferred: POWER ON / POWER OFF commands present
  - queryable       # inferred: many status/information request commands present
  - levelable       # inferred: volume, brightness, contrast, lamp/light adjust commands present
  - routable        # inferred: INPUT SW CHANGE input-terminal switching present

Actions

# Binary protocol notes (apply to every action below):
#  - Bytes are hexadecimal, space-separated, as written in the source.
#  - {checksum} = low-order one byte (8 bits) of the sum of ALL preceding bytes.
#  - Frames sent by the controller carry no ID1/ID2; the projector's response
#    echoes back <ID1> (control ID) and <ID2> (model code) plus a checksum.
#  - Success response opcode = command opcode | 0x20; error response opcode = command opcode | 0x80.
#  - This manual is a shared Sharp/NEC projector command reference; some DATA01
#    value lists (input terminal, aspect, eco mode, sub-input, base model type)
#    live in a separate appendix not present in this source - marked UNRESOLVED.

Notes

• Shared manual: BDT140013 Rev 7.1 is a common Sharp/NEC projector command reference; not all listed commands/features apply to every model. Several value lists (input terminal, aspect, eco mode, sub-input, base model type) are defined in a separate "Supplementary Information by Command" appendix not present in this source excerpt.
• Frame structure: Controller→projector commands carry no ID1/ID2 bytes (the projector infers control/model IDs). Projector→controller responses echo <ID1> (control ID set on projector) and <ID2> (model code). Every frame ends in <CKS>, the low-order byte of the sum of all preceding bytes.
• Response opcodes: success = command opcode with bit5 set (e.g. 02h→22h, 03h→23h, 01h→21h, 00h→20h); error = command opcode with bit7 set (e.g. 02h→A2h, 03h→A3h, 00h→A0h).
• Baud rate: five rates are supported (115200/38400/19200/9600/4800); the source does not state which is the factory default.
• Two-lamp models: Lamp 2 selectors (DATA01=01h) apply only to two-lamp projector models.
• Usage time granularity: lamp/filter usage times are obtainable in one-second units but are updated only at one-minute intervals.

Spec done. 53 actions (binary hex payloads verbatim + checksum rule). Both serial + TCP 7142 transport. Gaps marked `UNRESOLVED` (appendix value lists, default baud, firmware).
