Sharp-NEC PA1004UL Series Control Spec

Summary

Laser projector supporting both serial (RS-232C) and wired TCP/IP control. TCP port 7142 is used for command communication. Supports power control, input routing, picture/sound mute, lens positioning, and comprehensive query commands for projector status.

Variables

# UNRESOLVED: no discrete settable parameters outside of action commands

Events

# UNRESOLVED: no unsolicited event notifications described in source

Macros

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

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: no safety warnings or interlock procedures in source
# Note: Some models cannot receive commands in standby mode (see standby mode appendix)

Notes

Command format: 20h [ID1] [ID2] LEN [DATA...] CKS (hexadecimal). Response includes ERR1/ERR2 codes for error reporting. Checksum is low-order byte of sum of all preceding bytes. Some models cannot receive commands in standby mode — see appendix table for model-specific standby mode settings.
