NEC NP-PH1202HL Series Control Spec

Summary

Binary control protocol for NEC NP-PH1202HL Series projectors over RS-232 serial and TCP/IP (wired LAN). Commands are sent as fixed-format hex byte sequences with a trailing checksum. Covers power, input switching, mute, picture/volume adjustment, lens control, shutter, freeze, eco mode, edge blending, PIP/Picture-by-Picture, and extensive status querying.

Transport

protocols:
  - serial
  - tcp
serial:
  baud_rate: [115200, 38400, 19200, 9600, 4800]
  data_bits: 8
  parity: none
  stop_bits: 1
  flow_control: hardware  # RTS/CTS pin assignment documented
addressing:
  port: 7142  # TCP port for wired LAN command interface
auth:
  type: none  # inferred: no auth procedure in source

Traits

traits:
  - powerable    # inferred from POWER ON / POWER OFF commands
  - routable     # inferred from INPUT SW CHANGE command
  - queryable    # inferred from extensive status request commands
  - levelable    # inferred from VOLUME ADJUST, PICTURE ADJUST commands
  - muteable     # inferred from picture/sound/onscreen mute commands

Events

# UNRESOLVED: no unsolicited notification events documented in source; all responses are command-reply

Macros

# UNRESOLVED: no multi-step sequences explicitly described in source

Safety

confirmation_required_for: []
interlocks: []
notes: >-
  The error status response (command 009) includes interlock switch open detection (DATA09 Bit1),
  cover error (DATA01 Bit0), and mirror cover error (DATA03 Bit5).
  No explicit safety interlock procedure is documented in the command reference.
  # UNRESOLVED: full safety/interlock procedures not documented in this command reference

Notes

The protocol is entirely binary (hex byte sequences), not ASCII. Each command frame includes a checksum calculated as the low byte of the sum of all preceding bytes. Responses include error codes (ERR1/ERR2) on failure. The device uses a Control ID (ID1) and Model Code (ID2) in responses that vary per unit.

Power ON/OFF commands block all other commands during the power transition (including cooling time for power off). Some models cannot receive LAN commands in standby mode.

Picture mute, sound mute, and onscreen mute are automatically cancelled on input terminal switch or video signal switch. Sound mute is also cancelled on volume adjustment.

Lens control supports both timed drives (0.25s, 0.5s, 1s) and continuous drives (stop by sending 00h). While the lens is being driven, the same command can be reissued without stopping first.

Usage time counters update at one-minute intervals despite returning one-second precision.

The supplementary appendix tables for input terminal codes, aspect values, and eco mode values do not include a specific row for the NP-PH1202HL series; only NP4100, NP-Mxxx, and NP-MExxx models are listed.
