Safety
confirmation_required_for: []
interlocks: []
# UNRESOLVED: source does not contain explicit safety warnings, interlock procedures, or power-on sequencing requirements. Source mentions projector ID 00=99 addressing and a power-on password (S002) but no safety-critical interlocks.
Notes
- Frame format: every command terminated by
<CR>(0x0D). Projector returns P (pass) or F (fail, sometimesF 00). - Projector ID addressing: ID 00 broadcasts to all projectors; 01-99 targets a specific unit. ID is set via S047.
- Backward-compatible values: many On/Off commands accept 2 as an alias for Off (legacy firmware compatibility). Listed in the
valueenum for each. - Multi-sheet source: the source document contains three protocol sheets. This spec covers the first sheet ("Std DLP"), which the source flags as the protocol for the INL21xx series (S036 specifically notes INL2156, INL2158, INL2159). Sheets 2 (IN13xST, IN213x, INL314x, INL412x) and 3 (IN102x-105x) describe a different protocol family using
(CMD arg)syntax at 19200 baud with a different timing model (20s lamp ignition, 10s power down, 8s source change, 5ms intercommand, 2ms intercharacter); they are NOT covered by this spec. - Source typos (not auto-corrected):
- S054 has a blank ASCII Code cell in the on-row; the hex column is repeated from S053 (Signal Automatic On shares opcode 0091 with Screen Type).
- S075 ("Display message on the OSD") hex column repeats S072's 0200 opcode — likely a transcription error in the source.
- S065 and S066 are duplicate rows with identical payload but different "P.S" notes about security state; only one action retained.
- R013 lists two projection-info block variants (different source-encoding tables) with no clear criterion for choosing; both shown in source notes.
- R004 has two source-encoding mappings within one row (legacy vs current model variants).
- Source format convention: each ASCII command begins with
~followed by a 4- or 5-digit opcode, a space, the value, and<CR>. The "HEX Code" column encodes the ASCII bytes (so7E=~,30=0,20= space,0D= CR). - Security password: S002 (power on with password) and S046 (security on/off) require a 4-digit password appended as
~nnnn. When security is enabled, password is required on protected commands (per source Note 1).

Known Gaps
- "exact models in the INL21xx series not enumerated in source; S036 notes mention INL2156, INL2158, INL2159 specifically."
- "UART16550 FIFO disable stated as \"Disable\" in source; not a standard config knob, noted here."
- "source has a typo here (7E 30 30 32 30 30) - opcode 0200 collides with S072; S072 also 0200."
- "source does not contain explicit safety warnings, interlock procedures, or power-on sequencing requirements. Source mentions projector ID 00=99 addressing and a power-on password (S002) but no safety-critical interlocks."
- "firmware version compatibility not stated in source. The \"INL21xx series\" model range is named only in S036's range note; the source does not enumerate which model numbers belong to the series."
