Building a Smarter System Through

Ethernet: Introducing the IPL T S2

n a school of 20 classrooms, each has a projector, computer, VCR, and

switcher. In one classroom, a teacher’s lesson ends abruptly when the

projector’s bulb fizzles. In another, several students are disappointed

when they discover they can’t view a scheduled video because the

projector is missing. In the administrative office, the monthly bill shows

a jump in electricity use, and the maintenance crew is ordered to spend

the last 30 minutes of the day powering down all classroom equipment.

What’s wrong with this picture?

Not only is valuable learning time

disrupted and lost, but the teachers must

spend time troubleshooting equipment

needs they may not be trained to examine.

In addition, the maintenance crew’s time

traversing from room to room could be

better spent on more pressing school

needs.

Management of such an environment

has just gotten easier. The solution is the

Extron IPL T S2, a new and compact

Ethernet-to-serial interface that allows

technicians to access, monitor, and

troubleshoot A/V equipment remotely. The

IPL T S2 enables users to connect any

powered Extron or third-party A/V product

with a serial control port to a LAN, WAN,

or the Internet, providing all the benefits

of Ethernet control. This simplifies the

operation and administration of any

FEATURED PRODUCT Introducing the IPL T S2 (cont.) attached serial device, including projectors, cameras, and displays. A Better Way Ultimately, the IPL T S2 allows A/V professionals to build smarter systems. It’s an inexpensive way to reduce equipment downtime, lower maintenance costs through preventive service, and help manage devices via a corporate LAN or the Internet. A/V professionals and their customers benefit by having more flexibility and upgradeability, even over long distances.
PAGE 3
FEATURED Easy Setup The two bi-directional serial ports on the IPL T S2 can be used as direct connections to control two independent devices simultaneously or as pass-through connections within a system. Housed in a small and rugged quarter rack, 1U high enclosure, the IPL T S2 is easy to integrate into existing and new A/V systems, and can be mounted alongside Extron VersaTools™ products. Its versatile mounting options also allow it to be mounted under a desk or on a projector.

ANDREW ONLINE by Andrew Edwards, President of Extron Electronics Progress Report: Union of Extron and Inline Going Well S ince our announcement in August of the combination of Extron and Inline, the support staffs from both teams have been working overtime to learn both product lines. I was talking with our applications engineers recently, and although they were overwhelmed at first, the similarities of the two product lines have helped them come up to speed quickly.

T E C H N I C A L LY SPEAKING... by Steve Somers, Vice President of Engineering SDI Through Analog Video Distribution Equipment: A Good Idea? A /V applications for digital video over the serial digital interface, or SDI as it’s commonly called, are on the rise. Originally just the realm of television production and broadcast operations, SDI is used more often to convey professional quality component video among systems.

Pre-emphasis, or peaking, which may be beneficial to analog computer graphics transmission, can cause distortion or group delay effect, further limiting reliable serial digital data recovery. Group delay is the rate of change of signal phase shift with respect to frequency. Linear phase shift is a requirement for SDI routing devices.

TROUBLESHOOTING TIPS Eliminate Your Sync Problems, Part II A Shotgun Approach to Troubleshooting Sync Problems in RGBHV Systems O ne of the most common problems affecting high-resolution display systems is bad sync, which occurs when either one (or both) of the H and V signals is not effectively delivered to a display device. As discussed in the last issue of ExtroNews bad sync can exhibit itself in a number of different ways, including a flashing image or no image at all.

In some extreme cases, when the application has justified the expense, the Extron RGB 202 Rxi has been used to resolve this type of problem. Scenario 4 – Cable Problems A “Cable Problem”, refers to a defective, damaged, or poorly terminated cable exhibiting either a discontinuity or a short circuit between one end of a cable and the other.

TECH CORNER The Extron MLC 206 Emulation Software Simplifying Installation Through Preconfiguration W hen installing A/V equipment, what would you consider your most useful and time-saving tool? Consider emulation software—and other Extron-created tools—to help you complete the job using the least amount of time and labor. Emulation software allows you to complete a significant portion of Extron MLC 206 Controller your job away from the installation site and without the equipment present.

TECH CORNER in a meeting room: The MLC 206 can be set up so that pressing input 2 causes the system to switch from input 5 to input 2, send a video format change command (from S-video to RGB) to the projector, and trigger a relay to turn the spotlight on over a podium. Now the audience can see the laptop-based presentation and the speaker.
