NEC E422-R Control Spec

Summary

NEC professional projector supporting both RS-232C serial and wired LAN (TCP/IP) control. Supports power management, input routing, picture/sound muting, lens control, eco mode, and comprehensive status querying via hexadecimal command protocol.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 7142  # TCP port for LAN control
serial:
  baud_rate: 115200  # also supports: 38400, 19200, 9600, 4800
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: none
auth:
  type: none  # inferred: no auth procedure in source

Traits

- powerable
- routable

Variables

# UNRESOLVED: continuous parameters like brightness, contrast, volume are
# handled via Actions (picture_adjust, volume_adjust) rather than
# independent Variables. No standalone settable parameter commands
# beyond what is covered in Actions.

Events

# UNRESOLVED: no unsolicited event/notification mechanism described in source.
# Device only responds to commands; does not push status autonomously.

Macros

# UNRESOLVED: no explicit multi-step macros described in source.

Safety

confirmation_required_for: []
interlocks:
  - type: standby_mode_requirement
    description: Some models require specific standby modes to receive commands via serial or LAN. Serial supported modes: Normal, Active, Eco, NORMAL, NETWORK STANDBY, SLEEP, OFF, ON, STANDBY POWER ON. LAN supported modes: Normal, NORMAL, NETWORK STANDBY, SLEEP, HTBaseT STANDBY, OFF, ON, STANDBY POWER ON. Supported modes vary by model.
  - type: power_transition_blocking
    description: While POWER ON command is executing, no other command is accepted. While POWER OFF command is executing (including cooling time), no other command is accepted.
# UNRESOLVED: voltage, current, power consumption specifications not provided
# UNRESOLVED: no explicit safety interlocks for lens travel limits described

Notes

Command Protocol Format: All commands use hexadecimal notation. Basic format: [PREAMBLE] [CMD] [ID1] [ID2] [LEN] [DATA...] [CKS]. Checksum (CKS) = low-order byte of sum of all preceding bytes.

Control ID: Commands require <ID1> (control ID set on projector) and <ID2> (model code varies by model).

Serial Config: The projector supports multiple baud rates (115200/38400/19200/9600/4800 bps). No auto-baud detection described; the higher rate may need to be negotiated or set manually.

LAN Control: TCP port 7142. No mention of HTTP/REST protocol; commands are sent raw over TCP.

Known Gaps

- "exact model E422-R confirmation; manual covers multiple projector models; some commands reference appendix for values not fully enumerated in source"
- "commands 053-3 through 053-11 partially documented; lens memory appendix values not fully enumerated in source"
- "continuous parameters like brightness, contrast, volume are"
- "no unsolicited event/notification mechanism described in source."
- "no explicit multi-step macros described in source."
- "voltage, current, power consumption specifications not provided"
- "no explicit safety interlocks for lens travel limits described"
- "full appendix tables for input terminal codes by model variant not reproduced in source"
- "standby mode compatibility matrix per model not enumerated"
- "HDBaseT control mentioned but not detailed"
- "firmware version compatibility not stated"
- "some DATA01/DATA02 byte values in command examples include extra trailing bytes that appear to be part of the DATA payload rather than separate fields (e.g., \"02h 00h 00h 00h 00h 02h\" — the 02h after LEN may be part of the data length encoding)"
