Variables

# Settable parameters are represented as parameterized Actions (VOLnn, BRTnn, CONnn).
# No additional settable variables documented in source.

Events

# No unsolicited notifications documented in source.

Macros

# No multi-step sequences documented in source.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no explicit safety warnings or interlock procedures.
# Lamp ignition delay (20s) and power down delay (10s) noted in source are timing
# characteristics, not interlocks; see Notes.

Notes

• RS-232 settings stated in source: 19200 baud, 8 data bits, no parity, 1 stop bit, no flow control.
• Timing constraints stated in source: lamp ignition delay 20s; power down delay 10s; source change delay 8s; minimum intercommand delay 5ms; minimum intercharacter delay 2ms.
• Commands are ASCII strings enclosed in parentheses; "!" suffix variants command the operation and elicit a return code.
• Source support matrix has three model-family columns (IN134ST/IN136ST/IN138HDST; IN2134/IN2136/IN2138HD; INL3148HD/INL3149WU/INL4128/INL4129/IN1048SL/IN1049SL). Computer2 (SRC1), S-VIDEO (SRC12), and HDBaseT (SRC17) are unsupported in the first two families; IPM (ECO mode) and all lamp-hour commands are unsupported in the third family.

summary: "All 121 spec wire-literal commands appear verbatim in source RS-232 table; transport parameters (19200 baud / 8-N-1 / no flow control) are stated in source header. (6 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "source sheet is titled \"IN13xST IN213x INL314x INL412x\" and lists per-family support columns (IN134ST/IN136ST/IN138HDST, IN2134/IN2136/IN2138HD, INL3148HD/INL3149WU/INL4128/INL4129/IN1048SL/IN1049SL); IN5312/IN5314 are not explicitly named in the source, so per-command support for these exact models is unconfirmed"
- "source contains no explicit safety warnings or interlock procedures."
- "IN5312/IN5314 not explicitly named in source; which support column applies is unknown"
- "no TCP/IP, UDP, or network control documented in source"
- "physical connector type (DB9/DE9 pinout) not stated in source"
- "firmware version compatibility not stated in source"
