Sharp/NEC PN-HC861 Control Spec

Summary

Projector control spec for the Sharp/NEC PN-HC861, covering RS-232C serial and wired/wireless LAN (TCP) control. Commands are binary frames expressed in hexadecimal; each command frame ends with a checksum byte computed as the low-order byte of the sum of all preceding bytes. The device exposes power, input selection, mute, picture/volume/lens adjustment, lens memory, status queries, and PIP/edge-blending operations.

Transport

# Both serial and LAN are explicitly documented in the source (§1.1, §1.2).
protocols:
  - tcp
  - serial
addressing:
  port: 7142  # source §1.2 "Port number": TCP 7142
serial:
  baud_rate: 9600  # one of 115200/38400/19200/9600/4800 bps stated; default not specified
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated (source lists "Full duplex" communication mode only)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands (015, 016)
  - queryable    # inferred: extensive request commands (009, 037, 060-1, 078-*, 097-*, 305-*)
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST (030-1, 030-2, 030-15)
  - routable     # inferred: INPUT SW CHANGE (018), AUDIO SELECT SET (319-10)

Actions

# Frame conventions (source §2.1-§2.3):
#  - Commands are shown verbatim as in source, in hexadecimal, space-separated.
#  - The LAST byte of each frame is the checksum (CKS) = (sum of all preceding
#    bytes) mod 256. For parameterized commands, the listed trailing byte is the
#    checksum of the shown literal; recompute when substituting <DATA> values.
#  - <ID1> = Control ID, <ID2> = Model code - appear in responses, not in the
#    command frames listed here. Read ID1/ID2 from the device.
#  - Response success frame: "2xh <cmd> <ID1> <ID2> <LEN> <DATA...> <CKS>"
#    (2xh = 20h/21h/22h/23h depending on command class).
#    Error frame:  "Axh <cmd> <ID1> <ID2> 02h <ERR1> <ERR2> <CKS>".
#  - kind: action  = sets/executes a discrete state
#    kind: query   = requests data; response carries the requested payload
#    kind: set     = sets a named parameter value

Notes

• Protocol class bytes: command frames begin with a class byte that also sets the response header: 00h→20h/A0h (078/084/305), 01h→21h/A1h (079), 02h→22h/A2h (015/016/018/020–025/050/051/052/053-*), 03h→23h/A3h (030/037/060/097/098/319).
• Checksum: every frame ends in CKS = (sum of all preceding bytes) mod 256. Verified against source example (POWER OFF: 02h+01h+00h+00h+00h = 03h).
• ID1/ID2: responses include Control ID (ID1) and Model code (ID2); command frames in the source do not carry them. ID1 is configured per projector; ID2 is model-specific. Neither value for PN-HC861 is stated in source.
• Error reporting: failure responses carry <ERR1> <ERR2> per source §2.4 error-code table (28 combinations, e.g. 02h 0Dh = "command cannot be accepted because the power is off", 02h 0Fh = "no authority for the operation").
• Time fields: lamp/filter usage returned in seconds, updated at one-minute intervals.
• Remote key codes (050): enumerated as a single parameterized command; the source lists 25 key codes as DATA values of one opcode, not as distinct opcodes.

Firmware version compatibility not stated."

Appendix \"Supplementary Information by Command\" referenced for input-terminal, aspect, eco-mode, and sub-input enums but absent from refined source. Firmware version compatibility not stated. Baud-rate default among the listed values not stated. Lens-target DATA01 enum (053/053-1/053-2) truncated in source body (only 06h=Periphery Focus visible). Flow control not specified."
