CHAPTER 2 TECHNICALLY SPEAKING

Multiple User / Multiple Platform KVM Switches

The dedicated processors in NTI’s Modular Matrix multiple user/multiple platform KVM switches ensure

reliable performance at all times. Each port has its own processor that emulates the keyboard and mouse for

the connected computer. This means that even PCs will not crash because the computer will always

“recognize” the attached mouse and keyboard, even when the switch activates another computer.

The power cycling utilized by NTI’s Sun KVM switch ensures that users can power the KVM switch up or

down without crashing the operating system on the attached computers. This feature can also be utilized on

NTI Universal and Universal Matrix KVM switches configured for the attached SUN computers.

NTI’s Modular Matrix multiple user/multiple platform KVM switches are also reconfigurable as needs

change. Plug-in cards make this possible. These cards are removable from the KVM switch so if an

application changes and the network administrator wants to use a port for a computer of a different platform,

all he need do is purchase the card, install it, and connect the computer. This eliminates the need to purchase a

whole new KVM switch.

Directional control ensures that the data retains its integrity and goes to the correct computer after the KVM

switch processes the information. Directional control also ensures that the output goes to the correct user in

the multiple user application. Up to eight users can control as many as 32 computers on the modular matrix

multiple user/multiple platform unit.

NTI’s multiple platform KVM switches lets users choose whichever keyboard and mouse platform they

prefer. The KVM switch recognizes the signals from each platform and translates the data to the appropriate

platform as necessary. This feature, unique to NTI, lets users continue to use their favorite control console.

Also, when more than one user selects the same computer, the KVM switch recognizes ALL keystrokes and

mouse movements from each user. The switch processes the signals and returns the output to all user

monitors – all users on the same computer see everyone else’s input, including their own.

Dual Redundant Power (DRP)

NTI’s Modular Matrix multiple user/multiple platform KVM switches are available with an optional dual

redundant power supply feature. This separate unit adds a backup power supply to each of the switch’s

voltage levels. This ensures that a power failure in one power supply does not take your KVM switch

system down because the backup automatically kicks in. Users can then replace the failed power supply

without interrupting the operation of the switch or requiring the powering down of the attached computers.

Classroom Applications

One of the most innovative ways to use KVM switch technology is in the classroom. NTI’s KVM Classroom

Commander gives the teacher, trainer, or instructor complete control of up to 32 computers in a class.

Through daisy chaining, instructors can have an interactive role with each student. They can observe students

working or send out video to the entire class.

The instructor’s video, keyboard, and mouse connect to a central box that contains eight ports for

communication and eight ports for video interface from student computers. Each port supports a chain of up

to four students for a total of up to 32 connected computers.

 The keyboard and mouse ports support 6-pin miniDIN female connectors for PS/2 systems. For serial

mouse systems, a converter is available.

 The video ports are 15-pin HD female connectors for VGA monitors. The unit supports a video bandwidth

of 150 MHz and 1600x1200 resolution.

 The unit supports either 110 or 220 VAC power sources at 50 or 60Hz.
