The ASK C420's remarkable flexibility starts with its ability to be ceiling mounted or carted between rooms for a high-end meeting room solution. With six inputs, there's no need for an external switcher for multiple presenters. Need to change lenses for different rooms? No problem. User-replaceable bayonet lenses can be changed without tools - just push and twist. Do-it-yourself installation is just the beginning of the C420's user friendliness. An intelligent, multi-language, backlit interactive display guides presenters through setup and use, providing instant feedback. Get even fewer support calls with color-coded connections that make changing configurations easy. And the C420 is easily networked right out of the box, with ProjectorNet software by InFocus Corporation. Gain complete control of the projector from your laptop with InFocus ProjectorManager, an application that turns any PC into an advanced projector remote control. Now users can remotely adjust projector settings from their laptop, switch sources, even access features not available from the projector's onboard menu system, including power management controls and presentation collaboration tools. If you're familiar with the ASK quality promise, you know the C420 is dependable and durable, delivering performance you can trust. Its built-in handle makes it easy to hold when moving it between rooms. Rubber bumpers give the C420 a sturdy, protective base.
