Sharp/NEC Ld Fe192 RS-232 / IP control commands

Summary

Projector control spec for the Sharp/NEC Ld Fe192. Supports RS-232C serial and wired/wireless LAN (TCP) control via a binary protocol using hex bytes with checksum. Covers power, input switching, mute, picture/volume/lamp adjustment, lens control and memory, status queries, and network settings.

Transport

protocols:
  - tcp
  - serial
addressing:
  port: 7142
serial:
  baud_rate: 115200  # source lists 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: full_duplex  # source: "Communication mode: Full duplex"
auth:
  type: none  # inferred: no auth procedure in source

Traits

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

Actions

# All command bytes verbatim from source. ID1=control ID, ID2=model code,
# CKS=checksum (low byte of sum of all preceding bytes). See Notes for checksum rule.

Variables

# UNRESOLVED: source defines adjustment ranges dynamically via GAIN PARAMETER REQUEST 3
# (upper/lower/default/current/wide/narrow widths per gain). No static variable table
# in source. See gain_parameter_request_3 query.

Events

# UNRESOLVED: source describes no unsolicited notifications. All responses are
# command/response (synchronous).

Macros

# UNRESOLVED: source documents no explicit multi-step sequences.

Safety

confirmation_required_for: []
interlocks:
  - "POWER ON: while turning on, no other command accepted (source 3.2)"
  - "POWER OFF: while turning off (incl. cooling time), no other command accepted (source 3.3)"
  - "DATA09 Bit1 of ERROR STATUS: interlock switch open error (source 3.1)"
# UNRESOLVED: no power-on sequencing voltage/current spec in source.

Notes

Binary protocol. Command frames start with leading byte indicating command class (00h/01h/02h/03h); responses echo with high bit set on first byte (20h/21h/22h/23h = success, A0h/A1h/A2h/A3h = error).
Checksum (CKS): sum all preceding bytes, take low-order one byte (8 bits). Example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.
Parameters: ID1 = projector control ID; ID2 = model code (varies by model); DATA?? = variable-length data; LEN = data length following LEN byte.
Error responses: carry ERR1/ERR2 pair. See source §2.4 for full error code list (00h/00h=unrecognized, 00h/01h=unsupported model, 01h/00h=invalid value, 02h/0Dh=power off, etc.).
Serial baud is selectable: 115200 / 38400 / 19200 / 9600 / 4800 bps. Spec lists highest as default representative; device must be configured to match.
TCP port 7142 for both send and receive (source §1.2).
Many input-terminal, aspect, eco-mode, and base-model-type value tables live in an external "Appendix: Supplementary Information by Command" not included in this refined source — those enum values are UNRESOLVED.
LAMP INFORMATION remaining life returns negative % if replacement deadline exceeded.


Spec done. 53 actions enumerated (all source command rows). Serial+TCP both populated from explicit source. Baud rate, port 7142, checksum rule all verbatim. Appendix enum values marked UNRESOLVED — not in refined source.

Notes

Binary protocol. Command frames start with leading byte indicating command class (00h/01h/02h/03h); responses echo with high bit set on first byte (20h/21h/22h/23h = success, A0h/A1h/A2h/A3h = error).

Checksum (CKS): sum all preceding bytes, take low-order one byte (8 bits). Example: 20h+81h+01h+60h+01h+00h = 103h → CKS=03h.

Parameters: ID1 = projector control ID; ID2 = model code (varies by model); DATA?? = variable-length data; LEN = data length following LEN byte.

Error responses: carry ERR1/ERR2 pair. See source §2.4 for full error code list (00h/00h=unrecognized, 00h/01h=unsupported model, 01h/00h=invalid value, 02h/0Dh=power off, etc.).

Serial baud is selectable: 115200 / 38400 / 19200 / 9600 / 4800 bps. Spec lists highest as default representative; device must be configured to match.

TCP port 7142 for both send and receive (source §1.2).
