Sharp/NEC P495 Control Spec

Summary

The Sharp/NEC P495 is a large-format professional LCD projector. This spec covers its external control interface over RS-232C serial and wired/wireless LAN (TCP), using a binary frame protocol documented in the Projector Control Command Reference Manual (BDT140013 Rev 7.1).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists supported rates: 115200/38400/19200/9600/4800 bps; device-selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # source states "Full duplex" communication mode; no hardware flow-control field stated
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable  # inferred from POWER ON / POWER OFF commands
  - queryable  # inferred from many status/information request commands
  - levelable  # inferred from PICTURE ADJUST, VOLUME ADJUST, OTHER ADJUST, LENS CONTROL
  - routable  # inferred from INPUT SW CHANGE (input terminal switching)

Actions

# Binary frame format (hex bytes, space-separated as in source):
#   <STX-like lead> <CMD> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# CKS = checksum = low-order byte of sum of all preceding bytes.
# Literal commands below are taken VERBATIM from source. Where a command is
# parameterized, the variable DATA bytes are shown as placeholders.

Notes

• Command/response framing (from §2.1): 20h 88h <ID1> <ID2> 0Ch <DATA01> - <DATA12> <CKS>. Lead bytes distinguish direction/result: 02h/03h/01h = command from controller; 22h/23h/21h = successful acknowledgement; A2h/A3h/A0h/A1h = error acknowledgement; 20h = command (info request).
• Checksum (<CKS>) = low-order byte (8 bits) of the sum of all preceding bytes. Worked example from source: 20h + 81h + 01h + 60h + 01h + 00h = 103h → checksum 03h.
• ID1 = control ID set on the projector; ID2 = model code, varies by model (must be read from device / operation manual).
• LEN = byte length of the DATA part following LEN.
• Error acknowledgement carries ERR1/ERR2 per §2.4 error code table (e.g. 02h 0Dh = "command cannot be accepted because the power is off"; 02h 0Eh = "command execution failed").
• Usage-time fields (lamp, filter) are returned in one-second units but refreshed at one-minute intervals.
• P495 specific values (input terminal enum, aspect enum, eco mode enum, base model type, sub-input values) are deferred to the "Supplementary Information by Command" appendix, which is not present in this refined source excerpt.

53 actions enumerated, one per source row. All hex payloads verbatim. Enums missing → appendix absent → marked UNRESOLVED.

## Known Gaps

```yaml
- "source does not state exact P495 model code (ID2) value; it varies by model and must be obtained from the device. Input-terminal enum values, aspect values, eco-mode values, and base-model-type values are referenced as \"see Appendix Supplementary Information by Command\" but that appendix is not present in the refined source excerpt."
- "source describes no unsolicited notifications; all responses are command acknowledgements."
- "source documents no named multi-step sequences."
- "source states no explicit confirmation/interlock procedures beyond"
- "ID2 model code for P495 not stated in source."
- "Appendix \"Supplementary Information by Command\" (input terminal, aspect, eco-mode, base-model-type, sub-input enums) not present in refined source excerpt."
- "firmware version compatibility not stated in source."
- "protocol version not stated in source."
- "power/voltage/current specifications not stated in this control-protocol source."
