BenQ LU9715 Control Spec

Summary

BenQ LU9715 laser projector controllable via RS-232 serial, TCP (port 8000 over LAN), or RS-232 over HDBaseT. Command format is <CR>*<command>=<value>#<CR>. Case-insensitive ASCII protocol. Supports power, source selection, audio, picture mode/settings, lamp mode, aspect ratio, 3D, blank/freeze, menu navigation, and various operational settings.

Variables

# No continuous settable variables with explicit numeric ranges found.
# Volume and picture parameters use incremental +/- commands only.

Events

# Source describes no unsolicited notifications.

Macros

# Source describes no multi-step sequences.

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source contains no safety warnings, interlock procedures, or power-on sequencing requirements

Notes

• Command format: <CR>*<param>=<value>#<CR> for writes; <CR>*<param>?#<CR> for reads.
• Commands are case-insensitive (uppercase, lowercase, mixed all accepted).
• Error responses: Illegal format (bad syntax), Unsupported item (valid but not for this model), Block item (valid but cannot execute under current conditions).
• Commands work when standby power is 0.5W or a supported baud rate is set.
• TCP control over LAN uses same command set as serial; commands must start and end with <CR>.
• Source table marks many commands No (unsupported on LU9715) — only Yes-marked commands included above.
• Default baud rate is not stated; must be checked from projector OSD menu.
