Summary

Sharp/NEC projector / large-format display control spec based on the "Projector Control Command Reference Manual" (BDT140013 Rev 7.1). The device exposes a binary command protocol over RS-232C serial and over TCP/IP (wired/wireless LAN). All commands are framed hexadecimal payloads with a trailing checksum byte (sum of preceding bytes, low-order 8 bits).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800; default not stated - UNRESOLVED which is default
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: source states "Full duplex" communication mode but does not specify flow control wiring beyond RTS/CTS pinout
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands present
  - queryable    # inferred: many *REQUEST commands return status values
  - levelable    # inferred: PICTURE ADJUST, VOLUME ADJUST, LAMP ADJUST present
  - routable     # inferred: INPUT SW CHANGE / AUDIO SELECT SET present

Actions

# Frame format: <HDR> <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID set on projector (00h when default).
# ID2 = model code (00h when default; varies by model - not enumerated in source).
# CKS = checksum = low-order 8 bits of the sum of all preceding bytes.
# Below, commands are shown verbatim from the source with ID1=00h ID2=00h as documented.
# Parameterized DATA bytes are shown as {DATAxx} placeholders.

# UNRESOLVED: aspect variable query path; audio select readback (319-10 has no paired request in source).

Events

# UNRESOLVED: source describes no unsolicited notifications. All responses are replies to issued commands.
# The protocol appears strictly request/response.

Macros

# UNRESOLVED: source describes no multi-step command sequences as macros.

Notes

  • Protocol is binary, framed, little-endian checksum. Every command ends in a single checksum byte = low-order 8 bits of the sum of all preceding bytes (including the leading header byte and ID1/ID2/LEN).
  • Response ACK byte (high nibble): 2xh for 02h-header commands, 2xh for 01h-header commands, 2xh for 03h-header commands, 20h-style for 00h-header commands; Axh ACK prefix denotes an error response carrying ERR1/ERR2. 23h prefix denotes a successful response with returned DATA.
  • ID2 (model code) is left at 00h in the documented examples; the model-code-to-device mapping table is not in this refined source. Operators targeting a specific model may need to substitute ID2.
  • Several commands reference an "Appendix: Supplementary Information by Command" for value enumerations (input terminal codes, aspect values, eco mode values, sub input setting values, base model types). That appendix is not present in the refined source document — all such enum values are marked UNRESOLVED.
  • Lamp/filter usage time is updated only at one-minute intervals despite being reported in one-second units.
  • Lamp remaining life (%) goes negative once the replacement deadline is exceeded.
  • POWER OFF enters a cooling period during which the device is unresponsive to all other commands.

Known Gaps

- "source does not explicitly confirm PN-HE651 is the targeted model for this manual; model name taken from the operator-provided device name. The manual is a generic projector command reference and does not list specific model codes (ID2 model-code table is referenced but not present in the refined source)."
- "source states \"Full duplex\" communication mode but does not specify flow control wiring beyond RTS/CTS pinout"
- "aspect variable query path; audio select readback (319-10 has no paired request in source)."
- "source describes no unsolicited notifications. All responses are replies to issued commands."
- "source describes no multi-step command sequences as macros."
- "no explicit power-on sequencing, voltage/current specs, or hard interlock procedures stated in source."
- "default baud rate not stated (source lists 5 supported rates)."
- "ID2 model code for PN-HE651 not present in source."
- "Appendix 'Supplementary Information by Command' (input terminal values, aspect values, eco mode values, sub input values, base model type values) is not in the refined source document."
- "authority / access-control model referenced by error code 02h 0Fh is not described."
- "flow control configuration beyond RTS/CTS pinout not specified."
- "whether wireless LAN uses the same TCP port 7142 is implied but not explicitly stated."
