Summary

Sharp/NEC large-format LED display / projector controllable over RS-232C (PC CONTROL, D-SUB 9P) and wired/wireless LAN (TCP). Control uses a binary framed protocol with hex command bytes, per-device control ID + model code, and a trailing additive low-byte checksum. Source: Projector Control Command Reference Manual (BDT140013 Rev 7.1) — a generic Sharp/NEC projector command catalogue applied to the FE025I2 model.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142  # TCP port stated for LAN command send/receive
serial:
  baud_rate: 4800  # one of: 4800 / 9600 / 19200 / 38400 / 115200 bps (switchable; default not stated)
  data_bits: 8

  flow_control: null  # UNRESOLVED: flow control not stated in communication-conditions table (RTS/CTS pins 7/8 present on D-SUB 9P connector)
auth:
  type: none  # inferred: no login/auth procedure described in source

Traits

traits:
  - powerable    # inferred from POWER ON/OFF commands (015/016)
  - routable     # inferred from INPUT SW CHANGE (018)
  - queryable    # inferred from numerous REQUEST/status commands
  - levelable    # inferred from VOLUME / PICTURE adjust commands
  - muteable     # inferred from picture/sound/onscreen mute commands

Actions

# Frame: commands use leading message-type byte (00h-03h).
# <ID1> = control ID, <ID2> = model code (placeholders shown as 00h 00h; set per device).
# <CKS> = checksum = low byte of sum of all preceding bytes.
# Responses echo with leading 2xh (success) / Axh (error) + <ERR1><ERR2>.
# All payloads below are verbatim from the source.

Variables

# UNRESOLVED: source documents settable parameters as discrete commands (see Actions:
# PICTURE ADJUST, VOLUME ADJUST, ASPECT, ECO MODE, LAMP ADJUST, etc.) rather than a
# unified variable registry. No separate variable list enumerated.

Events

# UNRESOLVED: no unsolicited notification / push mechanism described in source.
# All data acquisition is poll-based via REQUEST commands.

Macros

# UNRESOLVED: no multi-step command sequences described in source.

Safety

confirmation_required_for: []
interlocks: []
# Source notes operational interlocks (not safety interlocks per se):
#  - POWER ON/OFF reject all other commands while power transition / cooling in progress.
#  - Error status bitmap reports an interlock-switch-open bit (DATA09 Bit1) and
#    foreign-matter / mirror-cover / lens-not-installed errors - treat as device
#    health indicators, not a documented control interlock procedure.
# UNRESOLVED: no explicit safety warnings, power-on sequencing, or operator
# confirmation procedures stated in this command reference.

Notes

  • Binary framed protocol. Command message-type lead bytes: 00h/01h/02h/03h; success-response lead bytes 20h/21h/22h/23h; error-response lead bytes A0h/A1h/A2h/A3h.
  • Checksum = low-order byte of the sum of all preceding bytes (inclusive of message type, command code, ID1, ID2, LEN, and DATA bytes). Example given in source: 20h+81h+01h+60h+01h+00h = 103h → CKS = 03h.
  • <ID1> = control ID set on projector; <ID2> = model code (model-dependent). Command examples use 00h 00h placeholders — substitute real values and recompute checksum.
  • Serial cable must be a cross cable wired to PC CONTROL (D-SUB 9P): pin2↔3 (RxD/TxD), pin7↔8 (RTS/CTS), pin5 GND.
  • LAN: TCP port 7142 (stated). Wired 10/100 Mbps auto-sensing; wireless via optional wireless-LAN unit (manual refers to unit's own operation manual for details).
  • Usage-time fields update at 1-minute intervals despite 1-second resolution.
  • Two-lamp variant: Lamp 2 selectors (01h in lamp DATA01) only valid on two-lamp models.
  • Picture/Sound/Onscreen mute auto-clear on input/video-signal switch (and volume adjust for sound mute).

Spec complete. 53 actions enumerated (all source command rows). Binary payloads verbatim w/ checksums. Serial + TCP transport, port 7142 stated, baud options listed. Appendix enum tables marked UNRESOLVED (not in refined excerpt).

Known Gaps

- "firmware version not stated in source. Specific feature support per model is referenced to an \"Appendix / Supplementary Information by Command\" not included in the refined source, so several enum value tables (input terminal values, aspect values, eco-mode values, base model type values) are not fully enumerated here."
- "flow control not stated in communication-conditions table (RTS/CTS pins 7/8 present on D-SUB 9P connector)"
- "source documents settable parameters as discrete commands (see Actions:"
- "no unsolicited notification / push mechanism described in source."
- "no multi-step command sequences described in source."
- "no explicit safety warnings, power-on sequencing, or operator"
- "source \"Appendix / Supplementary Information by Command\" (input terminal values, aspect values, eco-mode values, base model type values, sub-input values) was not included in the refined excerpt, so those enum tables are referenced but not fully materialized."
- "default baud rate / flow-control setting not stated."
- "firmware version compatibility not stated."
- "this manual is a generic Sharp/NEC projector command reference (BDT140013 Rev 7.1); model-specific feature support for FE025I2 not enumerated in the excerpt."
