Summary

NEC E805 Series professional projector controllable via RS-232C serial or wired LAN (TCP/IP). TCP port 7142 is used for command transmission. Supports power control, input routing, picture/sound mute, volume, lens adjustment, eco mode, and comprehensive status queries. No authentication procedure described.

Variables

# UNRESOLVED: variables are primarily settable via Actions (eco_mode_set, lan_projector_name_set, etc.)
# No standalone variable getters beyond the query commands listed in Feedbacks

Events

# UNRESOLVED: no unsolicited event notifications described in source; device only responds to commands

Macros

# No explicit multi-step macros described in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no explicit safety warnings or interlock procedures in source
# Note: POWER ON command blocks other commands during execution
# Note: POWER OFF command blocks during cooling time
# Note: Some models require specific standby modes for LAN/serial control (varies by model)

Notes

  • All commands use hexadecimal notation with structure: [HEADER] [MODEL_CODE] [ID1] [ID2] [LEN] [DATA...] [CKS]
  • Checksum (CKS) = low-order byte of sum of all preceding bytes
  • Device returns error codes ERR1/ERR2 on command failure
  • Standby mode requirements vary by model for serial vs LAN control
  • Input terminal hex codes vary by model; Appendix lists common values
  • Lamp and filter usage times updated at 1-minute intervals despite 1-second resolution
