Summary
Eiki Pro V1700 3LCD laser projector controlled via RS-232C serial (PRO-V RS232 command set). Commands are ASCII strings beginning with C terminated by CR (0x0D). Two command classes: functional execution (return ACK/NAK + CR) and status read (return requested value or NAK + CR). Supports power, input selection, lens shift, focus, zoom, keystone, image mode, screen, menu, and various status queries including power state, input source, screen setting, temperature, lamp mode, and power-fault detail.
Transport
protocols:

baud_rate: 19200
data_bits: 8

# Note: source specifies "Asynchronous communication"; wiring is RS-232 cross (null-modem) cable.

type: none # inferred: no auth procedure in source
Traits
traits:
- powerable # inferred: C00 power on, C01/C02 power off present
- routable # inferred: input selection commands (C05, C36, C37, C35, C38, C32, C15, C16, C17)
- queryable # inferred: CR0/CR1/CR3/CR4/CR6/CR7/CR ALLPFAIL status read commands
Actions
# All payloads verbatim from source. Mnemonic is the ASCII payload; hex form
# shown in source as (NN NN NN NN) where last byte is CR (0x0D) terminator.
# Per source §2.1 each command = one line starting "C" ending CR.
# Notes:
# - C44 and C18 hex strings in source end with 0x00 not 0x0D (apparent source typo);
# preserved verbatim per policy. Implementer should verify against device.
# - "CR ALLPFAIL" has no hex string in source; ASCII payload used as documented.

type: string
description: >
Power failure detail returned by CR ALLPFAIL. Source enumerates line items
of the form "NNN <name>, <status>" covering MAIN and FAN-1..FAN-13, LENS, CW.
Returned as a multi-line block; exact framing not fully specified.
# UNRESOLVED: exact response framing / delimiter between line items not specified in source.
Variables
# No settable parameter with explicit value-range payload is documented in the
# refined source. Brightness, zoom, focus, lens shift, and keystone are exposed
# only as relative +/- or directional actions (see Actions), not as
# parameterized set-points. Direct absolute-level control not documented.
# UNRESOLVED: no parameterized settable variables present in source.
Events
# Source documents request/response only. No unsolicited notifications described.
# UNRESOLVED: no unsolicited event/notification documented in source.
Macros
# No multi-step command sequences described explicitly in source.
# UNRESOLVED: no macros documented in source.
Safety
confirmation_required_for: []
interlocks: []
# Source mentions cooling-down states (CR0 "20", "21", "24", "28-x") and
# temperature-anomaly-induced shutdowns ("88-x"), but does not document any
# safety interlock procedure or required power-on sequencing. C01 (Power Off
# immediate) vs C02 (Power Off) distinction implies timing behavior but is not
# described as a safety interlock.
# UNRESOLVED: no explicit safety/interlock procedures documented in source.
Notes
- Protocol framing: each command is one ASCII line beginning with
Cand terminated by CR (0x0D). Per source §2.1. - Two command classes: functional execution (return
ACK/NAK+ CR) and status read (return value orNAK+ CR). Per source §2.2–2.3. - Wiring: RS-232 cross (null-modem) cable between PC and projector. Per source §1.2.
- Baud rate is 19200 (not the common 9600) — stated explicitly in source §1.1.
- Source typos preserved verbatim per population policy:
C44(Still off),C0D(Blank on),C18(Image Blackboard), andCR4(screen setting query) all show a0x00terminator in the hex form where every other command uses0x0D(CR). Likely OCR/typo in vendor doc; implementer should verify against device behavior. CR ALLPFAILis the only command without a hex representation in the source; payload taken as ASCII verbatim.- Status enums for
CR0include hyphenated sub-codes (28-0..28-3,88-0..88-3) for per-sensor temperature anomaly reporting — preserved verbatim.
Spec ready. Source extracted all 56 functional + 7 status commands as separate actions (per coverage rule, no collapse). Three hex typos flagged verbatim, not normalized.
