Summary

Sharp/NEC projector (As96U Px39Ml) control spec covering RS-232C serial and wired/wireless LAN (TCP) control per the Projector Control Command Reference Manual (BDT140013 Rev 7.1). Commands are binary hex frames; each command/response is bracketed and uses a trailing checksum byte (CKS = low-order byte of the sum of all preceding bytes).

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: 115200  # source lists selectable rates: 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: null  # UNRESOLVED: flow control mode not stated in source (RTS/CTS pins present in pinout but no flow_control value documented)
addressing:
  port: 7142  # TCP port for command send/receive (stated)
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable      # inferred: POWER ON / POWER OFF commands present
  - queryable      # inferred: numerous status/information request commands present
  - levelable      # inferred: VOLUME ADJUST, PICTURE ADJUST, LAMP/LIGHT ADJUST present
  - routable       # inferred: INPUT SW CHANGE (input terminal switching) present

Events

# No unsolicited notifications documented. All responses are solicited command replies.
# UNRESOLVED: source documents no asynchronous/push event mechanism.

Macros

# No multi-step sequences explicitly described in source.
# UNRESOLVED: populate from source if vendor documents macros; none found.

Notes

  • Command/response frames are hexadecimal byte sequences. Frame layout: {cmdByte} {opByte} {ID1} {ID2} {LEN} {DATA..} {CKS}. Request frames replace {ID1} {ID2} with 00h 00h and embed the control ID/model code implicitly; the device echoes {ID1} {ID2} in responses.
  • Checksum (CKS): low-order one byte of the sum of all preceding bytes in the frame. Example: 20h 81h 01h 60h 01h 00h → sum 103h → CKS 03h.
  • ID1 = control ID set on projector; ID2 = model code (varies by model). Default values not stated in source.
  • Lens continuous drive (7Fh / 81h in 053 LENS CONTROL DATA02) must be stopped by sending 00h; while driving, re-issuing the same command moves without stop.
  • Volume/picture gain parameter ranges, aspect values, base model type values, eco mode values, input terminal values, and sub-input values are referenced to an Appendix ("Supplementary Information by Command") not included in this refined source.
  • Serial cable is a cross (null-modem) cable on the PC CONTROL D-SUB 9P port; LAN uses RJ-45 (10/100 Mbps auto-switchable, IEEE 802.3 / 802.3u). Wireless LAN details deferred to the wireless LAN unit operation manual.

Spec done. 53 commands enumerated verbatim, both serial+TCP transport. CKS + ID1/ID2 noted unresolved. Appendix enums flagged unresolved (not in refined source).

Known Gaps

- "model name spelled as given in input (\"As96U Px39Ml\"); exact marketing model string not confirmed inside the refined source text. Firmware compatibility range, flow_control mode, and ID1/ID2 default values not stated."
- "flow control mode not stated in source (RTS/CTS pins present in pinout but no flow_control value documented)"
- "source documents no asynchronous/push event mechanism."
- "populate from source if vendor documents macros; none found."
- "no power-on sequencing requirements or explicit safety warnings beyond command lockouts documented in this refined source."
- "firmware version compatibility not stated in source."
- "serial flow_control mode not stated (RTS/CTS pins wired but no flow-control setting documented)."
- "ID1 (control ID) and ID2 (model code) default/valid values not stated."
- "Appendix \"Supplementary Information by Command\" not present in refined source — enum value tables for input terminal, aspect, base model type, eco mode, sub-input not captured."
- "exact marketing model string for \"As96U Px39Ml\" not corroborated inside refined text (manual is generic projector command reference)."
