Summary

Sharp/NEC PN-LC652 projector control spec covering the external control protocol described in the Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device supports RS-232C serial control and wired/wireless LAN (TCP) control. Commands use a binary hex-byte frame with a trailing checksum byte.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]  # source: selectable baud rates
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control not stated (source lists "Full duplex" communication mode only)
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: POWER ON / POWER OFF commands
  - queryable    # inferred: many status/information request commands
  - levelable    # inferred: VOLUME ADJUST, PICTURE ADJUST commands
  - routable     # inferred: INPUT SW CHANGE command

Actions

# All command payloads are hex-byte frames copied verbatim from the source.
# Frame layout (per source §2.1): <B1> <B2> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID, ID2 = model code, CKS = checksum (low byte of sum of all preceding bytes).
# Fixed commands below show the literal payload as printed in the source (ID1/ID2 embedded as 00h).
# Parameterized commands show the template with the variable DATA bytes named.

Notes

  • Manual reference: "Projector Control Command Reference Manual", BDT140013 Revision 7.1.
  • Command frame: <B1> <B2> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1 = control ID set on projector; ID2 = model code; CKS = low-order byte of the sum of all preceding bytes.
  • Response first byte encodes block: 20h/21h/22h/23h (success, echoes command block high nibble) vs A0h/A1h/A2h/A3h (failure). Success responses with no requested data carry LEN=00h.
  • Fixed commands shown above embed ID1=00h ID2=00h as printed in the source's representative payload; the checksum byte in each is computed over the preceding bytes (e.g. POWER ON 02h+00h+00h+00h+00h = 02h).
  • Several enum/code lists (input terminal codes, aspect values, eco mode values, base model type codes, sub-input codes) are referenced by the source as "Appendix — Supplementary Information by Command" but are absent from this refined excerpt.
  • Serial baud is selectable across 4800/9600/19200/38400/115200 bps; data 8 bits, parity none, stop 1 bit, full-duplex. Flow control line is not specified.
  • LAN control uses TCP port 7142 for command send/receive.
