OVERVIEW

Sure you can use copper KVM extenders to access and control

a CPU from the next room or the next building. But what if you need to work with a CPU a half mile away, or if you need more security, or if you have to run cable right past a generator?

You need ServSwitchFiber Optic KVM Extenders. They greatly extend the distance between a computer CPU and a keyboard, mouse, and monitor—especially in electrically noisy environments.

Normal keyboard-,video-,andmouse-extensioncables— and the extenders that usethem—canonly go so far, and electromagnetic noise can limit their distance and reliability.

But with a fiber optic solution like the ServSwitch Fiber Optic KVM Extender, these concerns are a thing of the past. You can leave a CPU in a secured cabinet or data center while you operate it from a convenient remote user station.

Using at least three multimode fiber strands, the extender system can reach as far as 0.6 miles (1 km) on either 62.5-µmor50-µmfiber. Fiber extension technology ensures perfect monitor image quality— even at the farthest possible distances supported!

Each ServSwitch Fiber Optic KVM Extenderkit consists of two main components: a local module that you attach to an IBM® PC compatible CPU and a remote unit that you attach to the remote keyboard, monitor, and mouse console. We even offer a version for connecting stereo audio and serial devices, such as touch screens, to your KVM fiber optic extender setup.

And because the extenders support dual access, you can add a KVM console on the local end, too. That enables you to operate the PC from either the local or remote user station.

Or, if you prefer, you can use the local KVM ports to feed into a BLACK BOX®KVM switch.

The ServSwitch Fiber Optic KVM Extendersare compatible with

all standard keyboards and all standard 2-button,3-button,and wheel mice. Intelligent PS/2 keyboard and mouse emulation ensures that your PCs don’t lock up.

Locating a CPU away from your workstation has a number of advantages. For instance:

In industrial applications, you can protect delicate server circuitry against dust, debris, moisture, and equipment vibration and keep data communications safe from potential interference (emitting from induction furnaces or current or load generators, for example).

In environments where data security is the highest priority, you can protect against data theft and unauthorized installation of software.

It also simplifies the setup, maintenance, configuration and administration of server management workstations.

In addition to industrial applications, ServSwitch Fiber Optic KVM Extenders can be deployed in:

Call centers where you need to co-locatea number of user’s computers.

Retail or similar settings where you need to keep CPUs secure and apart from monitors in kiosks and digital signage displays, as well as user stations in publically accessible areas.

Any application where you require remote access control of mission-criticalservers and the cable connecting local and remote stations must be reliable and offer a high level of security.

No matter what their application, our compact KVM extenders feature an unobtrusive footprint, so you can set them up for operation in tight work spaces or data centers.

Technically Speaking

The ServSwitch Fiber Optic KVM Extenders‘ keyboard

and mouse interfaces are standard PS/2® type interfaces, so you can attach just about any standard PS/2 compatible keyboard and mouse to the unit. To attach a PC/AT® style keyboard with a5-pinDIN connector to the extender, you’ll need a keyboard adapter (to order, call our FREE Tech Support).

The extenders come with zip-stylecable for making VGA connections to your server; the audio/serial model comes with serial and audio CPU cables, too.

For monitoring operation, the remote module has a sevensegment display that continuously­ indicates link status. In addition,

Device Ready LEDs on both local and remote units inform you of their operational status, so you can troubleshoot­ at either end.

The ServSwitch Fiber Optic KVM Extenders support all

VGA graphics cards and VGA resolutions up to 1280 x 1024 @ 75

Hz. You can use them to transfer RGB as well as VGA (RGBVH) signals and, if necessary, convert signals to transfer RGB to VGA or from VGA to RGB. All you have to do is make a simple jumper adjustment on the extenders’ motherboards.

There’s no need to worry about the video getting horribly distorted at either end of the fiber optic link. By default, the KVM extenders operate with an automatic gain control (AGC) function enabled. With AGC enabled, the gain of each color signal is fixed to give colors the same white level (0.7 Vpp), and most video problems are cleaned up automatically.

In some applications, it may be necessary to switch off the AGC so you can optimize video (to remedy a chromatic aberration, for instance). For this, you just need to flip internal jumpers and tweak the manual brightness and contrast

potentiometer dials on the rear panel of each unit. You can also attenuate the optic budget to raise the optical loss to a value that corrects any unstable image. (To do this, you need fiber pigtail coupling connectors. For details, call our FREE Tech Support.)

The seven-segmentdisplay aids with troubleshooting video gain. For instance, if it shows an ”F,” you’ve adjusted the contrast on the unit too high and, with AGC no longer possible, you need to readjust the gain.

Extend serial data and stereo audio, too.

To add RS-232serial and audio extension capabilities to your

KVM-over-fiberextender application, order theACS335A-ASversion of the ServSwitch Fiber Optic KVM Extender. The circuit boards on its local and remote units support transmitting bidirectional stereo audio andfull-duplex19-kbpsserial data across the interconnecting fiber cable.

The serial ports on the ACS335A-ASsupport extending TX,

RX, RTS, CTS, DTR, and DSR serial signals (and, in some cases, RI and DCD signals, for which a wiring adapter may be required.) You can connect either one serial device requiring hardware handshaking or—usingbreakoutcable—upto three simple

2-wireserial devices (TX/RX only). No user adjustments are required for the serial connection.

For multimedia capability, connect a set of speakers or a headset or microphone to a workstation linked to the remote unit. The extenders transmit stereo audio bidirectionally and simultaneously across the fiber cable link. The extender local unit sends audio digitally (as part of a 16-bit,38.4-KHzsignal) fornear-CDsound quality at the remote end of the fiber interconnection.

The line-levelinterface is designed to receive output from a sound card or otherline-levelsource and connect to a set

of powered speakers at the remote console. No further setup is required unless a microphone is connected to the remote unit (in which case, you just need to ensure that your sound card is set up and wired to provide sufficient amplification).

Why Buy From Black Box?

 

Exceptional Value.

 

Exceptional Tech Support. Period.

 

Recognize any of these situations?

 

• You wait more than 30 minutes to get through

 

to a vendor’s tech support.

 

• The so-called“tech” can’t help you or gives you

 

the wrong answer.

 

• You don’t have a purchase order number and the

ACS335A-AS

tech refuses to help you.

 

• It’s 9 p.m. and you need help, but your vendor’s

 

tech support line is closed.

 

According to a survey by Data Communications­ magazine, 90%

 

of network managers surveyed say that getting the technical support

 

they need is extremely important when choosing a vendor. But even

 

though network managers pay anywhere from 10 to 20% of their

 

overall purchase price for a basic service and support contract, the

 

technical support and service they receive falls far short of their

 

expectations—andcertainly isn’t worth what they paid.

 

At Black Box, we guarantee the best value and the best support.

 

You can even consult our Technical Support Experts before you buy if

 

you need help selecting just the right component for your application.

 

Don’t waste time and money—callBlack Box today.
