Summary
Sharp/NEC NP ME361W projector control spec. Supports RS-232C serial and TCP/IP LAN control. Binary command protocol with hex-byte frames, checksum (low-order byte of sum of preceding bytes). 53 distinct commands covering power, input switching, mutes, picture/volume/aspect/lamp adjust, lens control and memory, status queries, eco mode, edge blending, PIP/PbP, audio select.

Variables
# UNRESOLVED: source documents parameter-setting sub-commands (picture adjust,
# volume adjust, aspect, eco mode, lens position) but exposes them as discrete
# actions rather than named settable variables. No separate variable namespace
# is described. Populate as actions instead.
Events
# UNRESOLVED: source describes only request/response model. No unsolicited
# notification / push event documented.
Macros
# UNRESOLVED: source documents no multi-step command sequences.
Safety
confirmation_required_for: []
interlocks:
- "POWER ON (015): no other command accepted while power is turning on."
- "POWER OFF (016): no other command accepted during power-off including cooling time."
# Source contains no explicit safety interlock procedure beyond power-state
# command-acceptance windows above. Error bitmap (009) surfaces interlock-switch-open
# (DATA09 Bit1) and cover errors - treat as status observability, not control interlock.
Notes
- Checksum (CKS): low-order one byte of sum of all preceding bytes. Worked example in source §2.2.
- Command/response frame format (hex):
20h 88h <ID1> <ID2> 0Ch <DATA01> - <DATA12> <CKS>. ID1 = control ID set on projector; ID2 = model code (varies by model). - Error responses use prefix A0h/A1h/A2h/A3h carrying
<ERR1> <ERR2> <CKS>. ERR1/ERR2 code table in source §2.4 (00h/00h=unrecognized, 02h/0Dh=power off reject, 02h/0Fh=no authority, etc.). - Usage-time queries (lamp, filter) update at one-minute intervals despite one-second resolution.
- Source refers to an Appendix "Supplementary Information by Command" for several value maps (input terminal, aspect, eco mode, sub input, base model type). Appendix not present in refined source → those params marked UNRESOLVED.
Spec done. 53 actions, all hex payloads verbatim. Multiple appendix-deferred value maps marked UNRESOLVED.
