Safety Precautions and Installation Guidelines

Safety Precautions and Installation Guidelines

To ensure reliable and safe long-term operation, please note the following installation guidelines:

• Do not use CATx devices to link between buildings—use fiber devices.

• Only use in dry, indoor environments.

• If the building has three-phase AC power, try to ensure that equipment connected to the Local and Remote units is on the

same phase.

• Try not to route a CATx link cable alongside power cables.

• Ensure that the system connected to the Local unit is connected to power ground.

• Ensure that the monitor connected to the Remote unit is connected to power ground and does not use an isolated power

supply.

• The Remote unit, Local unit, and any power supplies can get warm. Do not locate them in an enclosed space without any

airflow.

• Do not place a power supply directly on top of a unit.

• Do not obstruct a unit’s ventilation holes.

CAUTION: To safeguard against personal injury and avoid possible damage to equipment or property, please observe the
following:

• Only use power supplies originally supplied with the product or manufacturer-approved replacements. Do not attempt to

dismantle or repair any power supply. Do not use a power supply if it appears to be defective or has a damaged case.

• Connect all power supplies to grounded outlets. In each case, ensure that the ground connection is maintained from the outlet

socket through to the power supply’s AC power input.

• Do not attempt to modify or repair this product, or make a connection from the CATx link interface (RJ-45) or the fiber link

interface (SC duplex) to any other products, especially telecommunications or network equipment.

These are Class 1 Laser products. Multimode transmitters comply with IEC 825-1 and FD 21 CFR 1040.10 and 1040.11.
Single-mode transmitters comply with IEC 60825-1 and FDA 21 CFR 1040.10 and 1040.11. To meet laser safety requirements, the
transmitters shall be operated within the absolute maximum ratings.

CAUTION: The use of optical instruments with this product may cause an eye hazard. All adjustments have been made at the
factory prior to shipment of the device. No maintenance or alteration to the device is required.

CAUTION: Tampering with or modifying the performance of the device will result in voided product warranty.

Usage Restrictions

Optical ports must be terminated with an optical connector or with a dust plug. Failure to adhere to the above restrictions could
result in a modification that is considered an act of “manufacturing” and will require, under law, recertification of the modified
product with the U.S. Food and Drug Administration (ref. 21 CFR 1040.10(i)).

Quick Setup Guide

Quick Setup

This section briefly describes how to install your KVM extender system and optimize the video signals. Unless you are an
experienced user, we recommend that you follow the full procedures described in the rest of this manual. Refer to the command
summary in Chapter 4 when following this procedure.

Install system

1. Connect remote unit to KVM.

2. Connect local unit to CPU or switch.

3. Connect local and remote units with matching interconnection cable
(CATx, multimode, or single-mode fiber).

4. Power up the system.

Carry out the Monitor Setup
procedure (see its manual and
Chapter 5 in this manual).

Carry out the VGA Input Setup procedure

(see Section 6.2 in this manual).

Figure QS-1. Quick Setup Instructions

ACS253A- CT

Quick Setup Guide

QS1. Video Input/Output

If possible, always use the DVI output from your computer’s video card and DVI input to a monitor. This provides the optimum
video signal. If you use a VGA output from your graphics source, the ACS253A local unit must digitize the signal prior to
transmission. Similarly, if your remote TFT screen uses a VGA input, it must digitize the signal from the remote unit.

In both cases, the built-in video processors must determine the resolution and pixel phase for an optimized digitization. Your DVI
Extender enables you to optimize the video signal manually or automatically using its on-screen utility (see Chapter 4). If you are
using a VGA input to a TFT monitor, please follow the manufacturer’s instructions.

You may have several possible options for video source output/monitor input. If this is the case, for the optimum video quality,
please select the highest-ranked available combination from the following table:

Table QS-1. Video Input and Output

Video Quality Local Unit Input Remote Unit Output

1 (high) DVI

2 DVI VGA

3 VGA DVI

4 (low) VGA VGA

DVI

QS2. Local Video Output

IMPORTANT: The local Video Out always carries the same signal your graphics card generates—this is opposite of the remote

out. The local unit does provide any signal translation for the local output.

This means, if you connect the local unit to a VGA graphics card, the local Video Out will alway carry VGA

signals, whether you connect a VGA or DVI screen to the remote unit. And the reverse is true: if you connect
the local unit to a DVI graphics card, the local Video Out will always carry DVI signals, whether you connect a
VGA or DVI screen to the remote unit.

The following table shows all possible input/output combinations:

Chapter 2: Overview

2. Overview

2.1 Introduction

The ServSwitch KVM Extender DVI/VGA system consists of a local unit (transmitter) and a remote unit (receiver). The local unit
connects directly to the computer (or a KVM switch system) using the supplied cable(s). The user console (keyboard, mouse and
monitor) attaches to the remote unit. The remote and local units communicate video and data information along the
interconnecting cable (see Figure 2-7). Local units offer dual access, enabling the connection of a second user console close to the
computer.

The ServSwitch KVM Extender DVI/VGA enables high-resolution video, PS/2/USB keyboard and mouse signals to be
communicated up to:

• 300 feet (100 m) over Category 5, 5e, 6 or higher (CATx) cable.

• 1200 feet (400 m) over multimode fiber cable (50/125μ).

• 600 feet (200 m) over multimode fiber cable (62.5/125μ).

1

• 6

⁄4 miles (10 km) over single-mode fiber cable (9/125µ).

In a digital applications (DVI input and output), there is no loss of picture quality regardless of extension distance, and no
adjustments are required. The extender also supports traditional analog VGA. All combinations of DVI and VGA (graphics cards
and monitors) are supported, allowing equipment to be mixed. In a mixed analog/digital application, some adjustment of the
video signal is necessary to optimize the analog-digital signal conversions. DVI KVM Extenders are equipped with various auto­matic and manual video correction tools in the OSD.

2.2 Terms Used in this Guide

The following terms are used in this guide:

CATx: Any Category 5, 5e, 6 or higher cable.

Multimode: Any multimode duplex cable, 50/125µ or 62.5/125µ

Single-mode: Any single-mode duplex cable, 9/125µ

PSU: The desktop power supply connected to the local/remote unit.

KVM: Keyboard, video monitor, and mouse.

Console: A keyboard, monitor, and mouse, plus optional serial/audio devices.

Dual Access: A system allowing connection of local and remote user consoles.

Single Head: An extender system that supports one monitor.

Dual Head: An extender system that supports two monitors.

2.3 Features

All members of the ServSwitch Brand DVI KVM Extender Series offer the following features:

• Support for high video resolution over extended distances: 1600 x 1200 @ 60 Hz over all allowed distances (all lower resolutions

with refresh rates of at least 75 Hz).

• All models come with dual access, to allow local or remote operation (Local DVI access limited to screen resolutions up to 1280

x 1024).

• All control and video tuning carried out using an on screen display (OSD) with settings stored in EEPROM memory.

• Local/remote unit firmware and settings are flash upgradable.

• Intelligent PS/2 keyboard and mouse emulation ensures PCs do not lock up and enables peripherals to be hot-plugged.
