Summary
Control command reference (BDT140013 Rev 7.1) for the Sharp/NEC NP-PX1004UL-W projector. Covers binary-frame control over both RS-232C serial and wired/wireless LAN (TCP). Frames are hex byte sequences with a trailing checksum byte; most commands return a success frame (2xh/A xh error) echoing ID1/ID2.
Transport
protocols:
- serial
- tcp
serial:
baud_rate: "115200/38400/19200/9600/4800 bps (switchable)"
data_bits: 8
parity: none
stop_bits: 1
flow_control: null # UNRESOLVED: flow control mode not stated in source communication table (RTS/CTS pins wired per D-SUB 9P assignment)
addressing:
port: 7142 # stated: TCP port 7142 for sending/receiving commands
auth:
type: none # inferred: no login/password/auth procedure in source
Traits
traits:
- powerable # inferred from POWER ON / POWER OFF commands
- queryable # inferred from numerous REQUEST (status query) commands
- levelable # inferred from volume, picture (brightness/contrast/etc.), and lens position adjust commands
Actions
# Frame layout (request): <type> <command> <ID1> <ID2> <LEN> <DATA...> <CKS>
# - ID1 = control ID set on projector (source lists request frames with 00h)
# - ID2 = model code (source lists request frames with 00h)
# - CKS = checksum = low-order byte of sum of all preceding bytes
# Parameterized commands show <DATA..> / <CKS> verbatim as in source.
# Fixed commands reproduce the literal checksum byte documented by the source.

Events
# No unsolicited notifications described in source. All responses are replies to commands.
# UNRESOLVED: populate if a separate notification section exists in the full manual.
Macros
# No explicit multi-step sequences described in source.
# UNRESOLVED: populate from source if applicable.

Notes
- Manual reference: BDT140013 Revision 7.1.
- Binary hex frames. Request frames are documented with literal
00h 00hin the ID1/ID2 byte positions; ID1 = control ID set on the projector, ID2 = model code (value for this model UNRESOLVED). Trailing<CKS>byte = low-order byte of the sum of all preceding bytes. - Response type byte encoding: success responses use high nibble
2with the command's category in the low part (20h/21h/22h/23h); error responses use high nibbleA(A0h/A1h/A2h/A3h) and carry<ERR1> <ERR2>. Error code table provided (ERR1/ERR2 combinations). - Picture mute, sound mute, and onscreen mute auto-clear on input/video signal switch (sound mute also clears on volume adjust).
- Lamp/filter usage time resolvable to one-second units but updated at one-minute intervals.
- Several commands reference an Appendix "Supplementary Information by Command" (input terminal codes, aspect values, eco mode values, base model types, sub-input values) that is not present in this refined source — those enums are UNRESOLVED.
