Sharp/NEC 4W B65Ft5U Control Spec

Summary

Sharp/NEC 4W B65Ft5U projector control spec derived from the Projector Control Command Reference Manual (BDT140013 Rev 7.1). The device supports RS-232C serial control and TCP/IP (wired/wireless LAN) control on TCP port 7142. Commands are binary frames consisting of a header, fixed bytes, optional DATA parameters, and a one-byte checksum (low byte of the sum of all preceding bytes).

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 9600  # source lists supported rates: 115200/38400/19200/9600/4800 - default not stated
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # UNRESOLVED: flow control not stated; source states "Full duplex" communication mode only
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred: 015 POWER ON / 016 POWER OFF commands present
  - queryable    # inferred: many REQUEST commands returning state
  - levelable    # inferred: PICTURE ADJUST / VOLUME ADJUST gain commands present
  - routable     # inferred: 018 INPUT SW CHANGE present

Variables

# Settable parameters exposed above as actions (PICTURE/VOLUME/ASPECT/OTHER ADJUST, LENS targets,
# LENS PROFILE, FREEZE, ECO MODE, EDGE BLENDING, PIP/PbP, AUDIO SELECT). No additional standalone
# variables documented.
# UNRESOLVED: none beyond action params

Events

# Source documents no unsolicited notifications. All device output is a response to a command.

Macros

# Source documents no multi-step macro sequences.

Safety

confirmation_required_for: []
interlocks:
  - command: power_on
    rule: "While POWER ON is executing, no other command is accepted."
  - command: power_off
    rule: "While POWER OFF is executing (including cooling time), no other command is accepted."
  - command: lens_control
    rule: "Continuous drive (DATA02=7Fh/-81h) must be stopped by subsequently sending DATA02=00h."
# UNRESOLVED: source contains no explicit safety interlock procedures or power-on sequencing
# requirements beyond the per-command execution locks noted above.

Notes

• Command frame structure: 20h 88h <ID1> <ID2> <LEN> <DATA01>...<DATA??> <CKS> (request header 20h/02h/03h/etc; response header A0h/22h/A2h/23h/A3h on success, error responses carry <ERR1> <ERR2>).
• Checksum (CKS) = low-order byte of the sum of all preceding bytes.
• ID1 = projector control ID; ID2 = model code (varies by model). Neither default value is stated in source.
• Usage-time queries update at one-minute intervals despite one-second resolution.
• Lamp remaining life (%) is returned negative if the replacement deadline is exceeded.
• Several DATA fields reference an "Appendix: Supplementary Information by Command" not included in this refined excerpt (input terminal codes, aspect values, eco-mode values, base model type codes, sub-input values).

matched_actions: 53
action_count: 53
confidence: medium
summary: "All 53 spec actions match literal hex commands in source; 100% coverage with no extra commands; transport parameters verified. (9 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "firmware version compatibility not stated in source"
- "control ID (ID1) and model code (ID2) values not documented; ID2 varies by model"
- "command timing / inter-command spacing not documented"
- "flow control not stated; source states \"Full duplex\" communication mode only"
- "none beyond action params"
- "source contains no explicit safety interlock procedures or power-on sequencing"
- "ID1 (control ID) default and ID2 (model code) for the 4W B65Ft5U not stated in source"
- "Appendix 'Supplementary Information by Command' values not present in refined source"
- "response timing / timeout values not documented"
