NEC UM351Wi Interactive Multi-Pen Whiteboard Kit

NEC UM351Wi Interactive Multi‑Pen Whiteboard Kit

The NEC UM351Wi is a cutting‑edge interactive desktop projector that transforms any surface into a dynamic whiteboard, enabling collaborative learning and presentation in classrooms, boardrooms, and training rooms. Its compact footprint (428 mm depth, 378 mm width, 112 mm height) and lightweight construction (5.6 kg) make it easy to relocate while still delivering powerful performance.

Projection Technology & Image Quality

The projector employs 3LCD technology, a proven method that delivers vibrant colors and sharp detail by using three separate liquid crystal displays for red, green, and blue. With a native resolution of WXGA (1280 × 800) and support for higher resolutions up to 1920 × 1080 (Full HD), the UM351Wi produces crisp images suitable for text, diagrams, and multimedia content.

A 3500 ANSI lumen brightness rating ensures visibility even in well‑lit rooms. The lamp’s power consumption is 200 W during operation and only 0.5 W in standby mode, contributing to energy efficiency. The light source boasts a service life of 5000 hours, reducing the need for frequent replacements.

The projector’s throw ratio of 0.36:1 allows it to project images as small as 1473 mm (58") up to 2794 mm (110") from a distance ranging between 0.1 m and 0.51 m, making it ideal for tight spaces.

Connectivity & Input Options

The UM351Wi offers a comprehensive array of ports:

• 2 HDMI full‑size connectors – perfect for modern laptops and media players.
• 2 VGA (D‑Sub) ports – compatible with older PCs and projectors.
• 1 DVI port – optional, not included in this model but supported by the hardware.
• 1 Composite video input – for legacy analog devices.
• 1 RS‑232 serial interface – enabling control via external systems or custom scripts.
• 3 USB 2.0 ports (Type‑A and Type‑B) – for connecting peripherals such as flash drives, keyboards, or mice.
• Ethernet LAN port – allowing network connectivity for firmware updates or remote management.

The projector also includes a microphone input, a single built‑in speaker, and a headphone output, enabling audio playback directly from the device. A DC‑in jack allows power via an external adapter if desired.

Interactive Features & Multi‑Pen Support

The UM351Wi is engineered for interactivity:

• Multi‑pen capability – supports up to 10 pens simultaneously, each with unique colors and pressure sensitivity. This feature turns the projected surface into a collaborative whiteboard where multiple users can write or draw at once.
• Handheld remote control (IR) – provides quick access to menu navigation, power functions, and interactive settings without needing to touch the projector.
• Manual focus with a fixed focal length of 4.7 mm ensures precise image clarity across various distances.
• Password protection safeguards the device from unauthorized changes to its configuration.
• Cable lock slot (Kensington) – enhances security by preventing accidental disconnection of cables.

Audio & Video Performance

The projector supports a wide range of analog video formats, including NTSC, PAL, SECAM, and their variants. Its vertical scan range (50–120 Hz) and horizontal scan range (15–100 kHz) accommodate diverse source devices.

With a digital zoom of 1.4×, users can enlarge the projected image without compromising quality, ideal for detailed diagrams or small text. The built‑in speaker delivers clear audio at a noise level of only 29 dB, ensuring minimal disruption in quiet environments.

Power & Environmental Compliance

The UM351Wi operates on standard AC input (100–240 V, 50–60 Hz), making it suitable for global deployment. It complies with CE, Gost‑R, TÜV GS, and RoHS certifications, guaranteeing safety, reliability, and environmental responsibility.

User Experience & Setup

The projector comes with a comprehensive manual and a quick start guide, simplifying initial configuration. Its compact size and integrated mounting brackets allow for flexible installation on desks or wall mounts.

Because the device is designed as an interactive whiteboard kit, it eliminates the need for separate touch screens or additional hardware. The combination of high brightness, multi‑pen interactivity, and robust connectivity makes the NEC UM351Wi a versatile solution for modern educational and corporate settings.

Conclusion

The NEC UM351Wi Interactive Multi‑Pen Whiteboard Kit delivers exceptional visual performance, extensive connectivity, and advanced interactive capabilities in a compact, user‑friendly package. Its blend of high brightness, multi‑pen support, and versatile input options positions it as an ideal tool for collaborative learning, brainstorming sessions, and dynamic presentations.
