AI4AVSummary
BenQ PW9500 DLP projector supporting RS-232 control via direct serial, LAN (TCP port 8000), and HDBaseT interfaces. The command examples use ASCII strings with <CR> delimiters; for LAN control, the source says commands work with or without those delimiters. Commands and behaviors are identical through serial. Supports power control, source routing, picture adjustment, lamp management, and OSD navigation.

Variables
# Settable parameters with + / - increment style commands (co-located with actions above).
# Contrast, Brightness, Color, Sharpness, Focus, Zoom, Keystone, Lens Shift each use
# paired increment/decrement actions rather than discrete set-value variables.
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, interlock procedures, or power-on sequencing
# requirements described in source
Notes
- Commands are ASCII strings. For LAN control, the source says commands work whether or not they start and end with
<CR>; commands and behaviors are identical through serial. - Error responses:
Illegal format(malformed command),Unsupported item(invalid for model),Block item(cannot execute under current condition). - Baud rate is configurable via command (
*baud=XXXX#) and readable (*baud=?#); defaults must be checked on OSD menu. - Lamp hour counters and lamp mode are queryable.
- High altitude mode toggle available.
- Lens shift and focus/zoom adjustments available.

summary: "All 115 action units match supported source commands with correct shapes; transport values are supported; the spec covers the supported catalogue (115 of 115). (10 unresolved item(s) noted in Known Gaps.)"
Known Gaps
- "audio commands (volume, mic volume, audio source) listed as NO support — unclear if functional on this model or upstream support missing"
- "configurable 9600/14400/19200/38400/57600/115200 bps — no default stated"
- "commands with NO support flag omitted from Actions above"
- "no unsolicited event notifications described in source"
- "no multi-step macro sequences described in source"
- "no safety warnings, interlock procedures, or power-on sequencing"
- "audio control commands (volume, mic volume, audio source) all marked NO support in source"
- "3D frame packing, 2D to 3D, NVIDIA modes marked NO support"
- "filter timer, firmware version, tint, keystone set-value not documented"
- "security/login code, AMX discovery, broadcasting not supported"
