Summary

Sharp/NEC projector control spec covering RS-232C serial and TCP/IP LAN control. Binary hex command protocol with checksum. Supports power control, input switching, picture/volume adjustment, lens control, lens memory, status queries, and system information requests. Source document is "Projector Control Command Reference Manual" (BDT140013 Revision 7.1), a generic reference covering multiple Sharp/NEC projector models.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200/38400/19200/9600/4800  # source lists all five as selectable
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: hardware  # inferred: RTS/CTS pins cross-connected in D-SUB 9P pin assignment table
addressing:
  port: 7142
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable  # inferred: POWER ON / POWER OFF commands present
  - queryable  # inferred: extensive status query commands present
  - levelable  # inferred: volume, brightness, contrast, color, hue, sharpness adjustment commands
  - routable  # inferred: INPUT SW CHANGE command present

Actions

# All commands use binary hex payloads. Last byte of each fixed command is the
# checksum (sum of all preceding bytes, low-order 8 bits). For parameterized
# commands, the checksum must be computed from the actual byte values.
# Response formats: 2Xh prefix = success, AXh prefix = error (with ERR1/ERR2).
# ID1 = control ID, ID2 = model code - projector fills these in responses.

Notes

  • Binary hex protocol. All commands are raw byte sequences with trailing checksum byte. Checksum = low-order 8 bits of sum of all preceding bytes.
  • Commands do not include ID1 (control ID) or ID2 (model code) in the payload — these appear only in projector responses, filled by the device.
  • Multiple baud rates supported (115200/38400/19200/9600/4800). Must match projector configuration.
  • Many parameter value enums (input terminals, aspect values, eco mode values, signal types) reference an "Appendix: Supplementary Information by Command" that is not included in the refined source document.
  • Response prefixes: 20h/21h/22h/23h = success response (with data if applicable), A0h/A1h/A2h/A3h = error response (with ERR1/ERR2 codes).
  • Error code table documents 20+ error combinations (unrecognized command, unsupported model, invalid value, memory errors, power off, no signal, etc.).
  • Lamp remaining life can return negative percentage if replacement deadline exceeded.
  • Usage times (lamp/filter) update at 1-minute intervals despite 1-second resolution.
  • Key code list (command 050) documents 24 remote control key codes including power, menu, navigation, source selection, volume, and eco mode keys.
