Summary
Sharp/NEC NP-PE455UL projector. Control via RS-232C serial (PC CONTROL D-SUB 9P) or wired/wireless LAN (TCP port 7142). Binary framed protocol with checksum. Covers power, input switch, mutes, picture/volume/aspect adjust, lens control + memory, shutter, freeze, eco mode, edge blending, PIP/PbP, and many status/error/lamp/filter queries (command reference BDT140013 Rev 7.1).

baud_rate: 115200 # source lists 115200/38400/19200/9600/4800 as switchable; 115200 is the top stated rate
# UNRESOLVED: source does not designate a single default baud rate; operator must select one of the listed values

Traits
traits:
- powerable # inferred: POWER ON / POWER OFF commands present
- queryable # inferred: many *REQUEST commands returning values
- levelable # inferred: PICTURE/VOLUME/LAMP adjust commands present
- routable # inferred: INPUT SW CHANGE command present (input selection)
Actions
# Framing: every command is hex-byte framed. Format per source §2.1:
# <CMD1> <CMD2> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# CKS = checksum = low byte of sum of all preceding bytes (per §2.2).
# Commands below use the literal fixed payload when source gives one (CKS shown
# verbatim from source). Parameterized commands show the variable DATA bytes.

Safety
confirmation_required_for:

- power_on # source: "While this command is turning on the power, no other command can be accepted."
interlocks:
- "Power-off locks out all other commands during cooling period."
- "Power-on locks out all other commands during power-on sequence."
- "ERR 02h/0Dh: command rejected because power is off."
- "ERR 02h/0Fh: no authority for operation."
# UNRESOLVED: source has no explicit safety interlock procedures (e.g. lamp-door,
# high-voltage). Error bitmap reports cover/interlock-switch/lamp errors but
# no documented recovery sequence.
Notes
Binary framed protocol, hex bytes. Frame format per §2.1: <CMD1> <CMD2> <ID1> <ID2> <LEN> <DATA...> <CKS>. ID1 = control ID configured on projector; ID2 = model code (varies by model — not stated for NP-PE455UL). Checksum = low byte of sum of all preceding bytes (worked example in §2.2). Success response leading byte = 2xh; error response leading byte = Axh with ERR1/ERR2.
Lamp/filter usage times returned in seconds, updated at 1-minute intervals. Negative remaining-life % means lamp replacement deadline exceeded.
Source repeatedly defers enum tables (input terminal, aspect, eco mode, sub-input) to an external Appendix titled "Supplementary Information by Command" — that appendix is NOT present in the supplied refined text. Those enums marked UNRESOLVED throughout.
Model code (ID2) for NP-PE455UL not stated — every command needs it; UNRESOLVED.
Spec output above. 53 commands enumerated (one per source row). Model code ID2 + appendix enums + default baud = main gaps marked UNRESOLVED.
