InFocus INL3148HD Control Spec

Summary

RS-232 control spec for InFocus IN13xST / IN213x / INL314x / INL412x projector families. Covers power, blank, source select, aspect ratio, ECO mode, volume, mute, lamp hour queries, ceiling orientation, brightness, contrast, preset modes, freeze, and keypad navigation. Connection is serial only; the source documents no network control.

Transport

protocols:
  - serial
serial:
  baud_rate: 19200
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable       # inferred from PWR power command examples
- routable        # inferred from SRC source-select command examples
- queryable       # inferred from PWR?/SRC?/VOL?/etc. query command examples
- levelable       # inferred from VOL, BRT, CON level commands

Variables

# No discrete variables beyond actions and feedbacks. Section retained for completeness.

Events

# UNRESOLVED: source documents no unsolicited notification events.

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlocks, or power-on sequencing requirements.

Notes

• Source RS-232 setting row explicitly states: Lamp Ignition delay = 20s, Power Down delay = 10s, Source change delay = 8s, Intercommand delay minimum = 5ms, Intercharacter delay minimum = 2ms. Apply when driving the projector.
• Source enumerates three model columns: IN134ST/IN136ST/IN138HDST, IN2134/IN2136/IN2138HD, INL3148HD/INL3149WU/INL4128/INL4129/IN1048SL/IN1049SL. Some commands (SRC1/SRC2/SRC12/SRC17/IPT/IPM, lamp-hour queries, lamp reset) are flagged "No" for one or two columns — implementer should check target-model support column.
• The "Yes/No" support columns in source likely indicate whether each model supports the command; not derivable which models were the operator's "INF70xx" target.
• Device name in input was "InFocus INF70xx"; no INF70xx model appears in source. INL3148HD chosen as representative spec_id; compatible_with.models lists every model the source covers.
• No networking, auth, login, or HTTP/REST commands in source. Serial-only.

summary: "All 121 spec actions (queries, sets, !-return variants) match source command table verbatim; transport row matches. (5 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "input device name was \"InFocus INF70xx\" but no INF70xx model appears in source — INL3148HD used as representative. The provided \"Known protocol\" was blank; populated serial from explicit RS-232 setting row in source."
- "source documents no unsolicited notification events."
- "source documents no multi-step macro sequences."
- "source contains no safety warnings, interlocks, or power-on sequencing requirements."
- "firmware version compatibility, port number (if serial over USB-to-RS-232 adapter), and whether the commands require CR/LF framing not stated in source."
