ViewSonic LS750WU Control Spec

Summary

The ViewSonic LS750WU is a laser projector controllable via RS-232C serial. This spec covers the full RS-232 command set documented by the manufacturer, including power, source selection, picture adjustment, 3D, audio, language, light source mode, CEC, HDMI format, and remote-key emulation commands. The projector also supports LAN-based control (web UI, Crestron RoomView port 41794, PJLink, SNMP, AMX, Xpanel); those interfaces are described in Notes, not the structured sections below.

Transport

# RS-232C only - the structured spec scope is the serial control port.
# LAN/web control info appears in Notes.
protocols:
  - serial
serial:
  baud_rate: 115200  # default per source; OSD also supports 2400/4800/9600/14400/19200/38400/57600
  data_bits: 8
  parity: none
  stop_bits: 1

Traits

# Evidence-backed only:
- powerable       # Power ON/OFF/TOGGLE writes + Status read
- routable        # Source input writes (D-Sub/Comp.1, HDMI 1, Composite Video) + Status read
- queryable       # many "Read/Status" commands across categories
- levelable       # Contrast/Brightness/Volume/Saturation/Sharpness increase/decrease + get-value

Feedbacks

# Source describes Read/Status commands but does not document the response

# decoding is left UNRESOLVED.
# UNRESOLVED: response frame format for Read commands not stated in source.
# Each Read above is implemented as `kind: query`; consumers must parse the
# returned bytes per the projector's own protocol spec (not supplied here).

Variables

# Discrete write actions cover the documented command set; no continuous

# Value" byte sequence for Volume (see volume_write_value action).
# UNRESOLVED: value range, units, and checksum recomputation for

Events

# UNRESOLVED: source does not document any unsolicited notifications
# the device sends back over RS-232. No Events section applicable.

Macros

# UNRESOLVED: source does not document any multi-step command sequences
# or built-in macros. No Macros section applicable.

Safety

# guidance. No safety-critical fields populated.

Notes

• RS-232 default is 115200 bps, 8/N/1, no flow control. The OSD Baud Rate menu allows 2400/4800/9600/14400/19200/38400/57600/115200; the source documents the default only.
• Pin assignment (DB-9): 1=NC, 2=RX, 3=TX, 4=NC, 5=GND, 6=NC, 7=RTS, 8=CTS, 9=NC. RTS/CTS are exposed but flow control is set to None.
• LAN/web control is out of scope for this spec but the projector also exposes:
  • Web UI (default admin password 0000 per source).
  • Crestron RoomView — IPID 02, reserved port 41794 per source.
  • PJLink, SNMP v1, AMX, Xpanel v1.10 — supported per source; the source defers to each standard's own documentation for the command set.
  • Standby LAN control must be enabled in ADVANCED > LAN Control Settings to reach the projector in standby.
• Control Method OSD setting: RS-232, USB, or HDBaseT (HDBaseT only on LS850WU/LS860WU — not applicable to LS750WU).
• Source list omits some inputs. The connection-port table lists HDMI 1, HDMI 2, USB, HDBaseT, Composite, S-Video, COMPUTER IN, etc., but the RS-232 Source input table only enumerates D-Sub/Comp. 1, HDMI 1, and Composite Video. HDMI 2 / S-Video / HDBaseT are not listed in the RS-232 source-input command set. UNRESOLVED: HDMI 2, S-Video, and HDBaseT source-selection opcodes are not in the source.
• Duplicate command — Reset Color Settings appears twice in the source with identical byte sequence under different headings (line 170 and line 265). Captured once as reset_color_settings; the duplicate is preserved as reset_color_settings_alt for fidelity.
• Volume Write Value is the only parameterized write in the source; the byte 0x11 is given literally without a stated value range or checksum rule, so it is left as a literal action with an UNRESOLVED note.
• AMX command payload is the literal ASCII string AMX per the source's command table.
• Checksum handling: the source lists each command as a fixed sequence ending in a checksum byte; this spec preserves the bytes verbatim. A separate, generic checksum-recomputation algorithm is not stated in the source and is not asserted here.
