The MLC 206 and AAP 104 have each

been outﬁtted with one IR Control Module

(IRCM). The MLC 206 has an Extron

IRCM-DVD+, which offers transport and

menu controls for a DVD player. The AAP 104

has an Extron IRCM-VCR, which provides re-

mote control of a VCR’s basic features.

The MLC 206 controls ﬁve sources. In

addition to the auxiliary VGA and auxil-

iary composite sources coming from the

HSA 400, the desktop computer, VCR, and

DVD player that are all mounted on the

cart are controlled with the MLC 206. “The

MLC 206 was chosen for the number of in-

puts it has, its ability to communicate with

the System 7SC, the modules for DVD player

and VCR control, and its relatively inexpen-

sive price,” Huberty said.

Making the Connection

Once the carts were assembled and load-

ed up with computer and A/V equipment,

the PTD staff wired everything by hand.

Huberty said that virtually no pre-manufac-

stated that the length of the cable runs and

termination varied from room to room.

“In some of the rooms we ran the cable

in the walls,” he said. “But if the cart was

moved to the middle of the room, which

some of our faculty members asked for, we

ran raceway molding on the ﬂoor so the

cable could be fed to the cart without any-

one tripping over it.”

Changing the Dynamics of Teaching

Even with a limited time allotted to get the

systems up and running, the PTD technicians

encountered very few problems. “The biggest

obstacle for this project was retroﬁtting,”

Huberty remarked. “Our job was to try and

get all of the requested equipment in a space

the faculty wanted and not have a noticeable

degradation of quality, both in the image and

in the instructor’s presentations.”

Largely because of the Extron products

that were used, Kennesaw was able to get

the most “bang for the buck.” As for how

the systems have been received, the universi-

ty’s faculty couldn’t be more positive in their

praise. “I love them!” exclaimed Dr. Gary

Roberts, Professor of Management in the

Management and Entrepreneurship depart-

ment, who uses the system in his classroom on

a daily basis. “They have completely changed

the dynamics of teaching. In fact, I ﬁnd it very

difﬁcult now to teach in a room without the

range of equipment offered on our carts. It’s

like going back a century in time.”

tured cable was used, with the exception

of two Extron VGA with Audio Cables that

include 15-pin HD male connectors and

audio cables with a 3.5 mm stereo mini

jack on each end. These are primarily used

to hook up the laptops.

While the carts were being wired, an-

other crew was in each room pulling and

terminating cables, hanging speakers and

projection screens, and installing the mul-

timedia XGA LCD video projector. “The

only infrastructure requirements not solely

handled by us were the electrical out-

lets, network jacks, and the replacement

of chalkboards with LCS (Liquid Chalk

System

) marker boards,” said Huberty.

As for connecting the projector to the

System 7SC, Extron BNC-5 Mini HR Cable

was used. Lighter, smaller in diameter,

and more convenient to install than stan-

dard coaxial cable, the Mini HR cable

offers excellent video performance for

carrying high resolution signals. Huberty

Each multimedia cart houses all of the classroom’s

A/V and IT equipment, including the Extron

System 7SC system switcher.
