NEC Exx2 RS-232 / IP control commands

Summary

NEC Exx2 projector RS-232C and TCP/IP control protocol. Supports serial (RS-232C cross cable) and wired LAN (TCP port 7142). Full duplex communication with checksum-based packet framing. Source documents 53 command groups covering power, input routing, mute, picture/sound adjustment, lens control, eco mode, freeze, PIP, edge blending, and status queries.

Transport

# Packet framing: command/response expressed as hex byte strings.
# General response frame: <type> <op> <ID1> <ID2> <LEN> <DATA...> <CKS>
# ID1 = control ID set on projector; ID2 = model code (varies by model).
# CKS = checksum = low-order byte of sum of all preceding bytes.
protocols:
  - serial
  - tcp
addressing:
  port: 7142
serial:
  baud_rate: null  # UNRESOLVED: no default stated in source; supported rates = 115200/38400/19200/9600/4800 bps
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none  # communication mode: full duplex (source 1.2)
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable    # inferred from 015 POWER ON / 016 POWER OFF
- routable     # inferred from 018 INPUT SW CHANGE
- queryable    # inferred from numerous status/error/information request commands
- levelable    # inferred from 030-1 PICTURE ADJUST / 030-2 VOLUME ADJUST

Actions

# Notes on payloads:
# - Fixed commands carry a complete literal hex payload including the checksum byte.
# - Parameterized commands show <DATA##> placeholders verbatim from source plus a
#   <CKS> placeholder; checksum = low-order byte of sum of all preceding bytes.
# - ID1 (control ID) / ID2 (model code) appear in responses, not in the literal
#   command bytes documented for these operations.
