System Switchers

Simplify Projector Control

rojector technology is evolving at a rapid pace. Several

years ago, only a handful of projector manufacturers

existed, and each made only a few different products. Today,

the projector market has grown to include several dozen

manufacturers with a whole range of product offerings.

continued on page 2

The expansion of the projector

market has given A/V professionals

a wider range of projector options

to choose from than ever before.

There is a projector available that

will meet the needs of virtually any

application. But what about

projector control options? Have

those control options kept up with

the pace of projector development,

particularly with the increasing

number of applications that have

more than one source for image

output?

Projector manufacturers initially

answered this question by making

their own, proprietary switchers.

However, these switchers could

only work with and control their

own brand of projectors. When

there were only a few projector

manufacturers and a few projector

models, this solution was a viable

one for professionals in the A/V

industry. But today, most A/V

dealerships stock many different

brands of projectors and need

system switchers that work with

them all. This is especially true

when the original projector needs

to be replaced with something

newer, smaller, and brighter.

Screen Control accept composite video, S-video, and RGB video. Each input also accepts stereo audio. The switcher’s line doubler increases the horizontal scan rate of the input signal by two times, making the output comparable to a 640 x 480 VGA signal. Figure 5. Universal projector control with room control features makes the System 7SC an all in-one solution for complex applications.

T E C H N I C A L LY So, What’s All This Cable Safety Rating Stuff Anyhow? So, what does all the safety alphabet soup mean? Table 2 (on following page) is a handy applications table that will help you organize the cable marking designations mentally. Plenum-rated cables (suffix “P”) are at the top of the cable safety food chain because they are constructed of materials having very low “fire load.” Fire load is the term used to describe how much fuel a given material provides a fire.

T E C H N I C A L LY While PVC contains chlorine, it is not fire resistant. PVC and polyolefin products must have concoctions of other elements added in order to achieve any degree of flame resistance. Most fire resistant compounds contain fluorine or are said to be fluorinated, such as FEP (fluorinated ethylene propylene). I Can’t Believe It’s Not Halogenated! European building authorities will not allow use of halogenated cables.

UNIQUE TECHNIQUES The Technological Forefront of Education T he University of Central Florida (UCF) was recently selected by Yahoo! as one of the most wired institutions of higher learning in the United States. Front view of a high-capacity, multimedia classroom. Classroom building with cutting-edge A/V systems at University of Central Florida. Last spring, UCF began their latest foray into the A/V world with a multitude of multimedia systems in mind for a new classroom building.

UNIQUE A professor’s laptop is hooked up to the A/V system through the Extron RGB 158xi computer-video interface. UCF staff discussed why the RGB 158xi was selected: “We chose this interface because it offers an electrical outlet. This outlet eliminates the expense of having an electrician install an electrical outlet in each podium. The RGB 158xi’s electrical outlet and VGA input connector are perfect for a laptop. Another plus is the rack ears.

TECH CORNER by Roger McCarten, Product Development Manager Using the System 7SC for Room Control E xtron recently introduced the System 7SC switcher. The System 7SC can be thought of as an all-in-one switching and control solution for conference rooms, classrooms, meeting rooms—any small to medium-sized application where the budget is limited. The System 7SC provides switching, projector control, and room control: everything needed for a single room application.
PAGE 19
TECH CORNER Room control through the System 7SC Once room control devices have been connected to the relays on the System 7SC, the user has a choice of several ways to control equipment in the room. The most obvious method is to use the front panel on the System 7SC, but this may not be convenient. As an alternative, an IR remote control (which is supplied with the switcher) can be used to control switcher functions, the projector, and room devices.

One day ADTECH Systems, Inc.’s David Crepeau of Wayland, MA, and his colleagues ran out of short wall plate screws. While installing long wall plate screws, Crepeau was struck by a stroke of on-the-job inspiration: “Wouldn’t a cordless power Tweeker be great!” So he made one—and it really works! Send us your photograph of how you use the Tweeker. If we publish it in a future issue of ExtroNews, we’ll give you a free VTG 150.
