BenQ W5800 Control Spec

Summary

BenQ W5800 laser projector controllable via RS-232 serial (direct, HDBaseT) or RS-232-over-LAN (TCP port 8000). Commands use ASCII format <CR>*<mnemonic>=<value>#<CR>. This spec covers power, source selection, picture settings, keystone, lamp control, 3D, and miscellaneous operations.

Variables

# UNRESOLVED: no settable continuous variables beyond those represented as actions

Events

# UNRESOLVED: source does not document unsolicited notifications

Macros

# UNRESOLVED: no multi-step sequences in source

Safety

confirmation_required_for: []
interlocks: []
# UNRESOLVED: source mentions standby power 0.5W requirement but no explicit safety interlocks

Notes

Commands case-insensitive. Illegal format returns Illegal format; unsupported commands return Unsupported item; blocked commands return Block item. LAN control wraps commands in <CR> delimiters identical to serial. Baud rate must be checked from projector OSD before connecting — multiple rates supported (9600–115200).

Known Gaps

- "multiple supported (9600/14400/19200/38400/57600/115200); check device OSD"

- "source does not document unsolicited notifications"
- "no multi-step sequences in source"
- "source mentions standby power 0.5W requirement but no explicit safety interlocks"
- "specific baud rate default not stated — must check OSD"
- "response format/structure not documented beyond error strings"
- "lamp `ltim` query — unit (hours?) not stated"
- "contrast/brightness/color/sharpness/fleshtone value ranges not stated"
