accordance with the manufacturer’s instructions, may cause inter­ference to radio communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct
the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emis­sion from digital apparatus set out in the Radio
Interference Regulation of Industry Canada.

Chapter 2: Overview
2. Overview
2.1 Introduction
The instructions in this guide assume a general knowledge of computer installation procedures, familiarity with cabling
requirements, and some understanding of USB devices.
NOTES provide additional useful and important information.
CAUTIONS provide important information about an operational requirement.
2.2 About the ServSwitch KVM Extender, HDMI and USB 2.0 over CATx
The Extender incorporates a proprietary USB and HD video technology, which enables users to extend both HDMI video and USB
2.0 up to 330 feet (100 m). The following proprietary USB features are included:
• True plug-and-play.
• Supports all major operating systems: Windows®, Mac OS X®, and Linux®.
• Reliable operation with USB 2.0 and 1.1 devices and hubs.
2.3 What‘s Included
• Local Extender
• Remote Extender
• (2) 5V DC power adapters
• USB Cable
• HDMI Cable
• Quick Start Guide and Warranty Information
NOTE: The product requires two power adapters, one for the local extender and one for the remote extender.
NOTE: This product supports CAT5e or better cabling (i.e., CAT6, CAT7, etc.). All references to “CAT5e” should be read as “CAT5e
or better.”
2.4 Requirements
To complete the installation, you will require the following items that are not included with the product:
• A computer that is USB compatible (with USB compliant operating system) and has an HDMI port;
• USB 1.1 or 2.0 compatible device(s);
• A minimum of CAT5e Shielded Twisted Pair (STP) cable with two CAT5e RJ-45 connectors (if using surface cabling), OR
•A
minimum of CAT5e cabling with two information outlets and two CAT5e patch cords with CAT5e RJ-45 connectors (if using
premise cabling).
NOTE: While CAT5e STP is the minimum category of twisted-pair cabling, for the best experience, and to minimize interference
and crosstalk, CAT6 STP or better is strongly recommended. When using CAT5e cabling, the layout and quality of your
cable runs and connections becomes extremely important. Please refer to the Cabling information in Section 2.5 for details.

Appendix A: Technical Glossary
Appendix A. Technical Glossary
Category 5 (CAT5) Network Cabling — Category 5 cable is commonly also referred to as CAT5. This cabling is available in
either solid or stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair). UTP
cables are not surrounded by any shielding, making them more susceptible to electromagnetic interference (EMI). STP cables
include shielding over each individual pair of copper wires that provides better protection against EMI. Category 5 has been
superseded by CAT5e cabling, which includes improved data integrity to support high-speed communications.
USB Cables — USB cables have two distinct connectors. The Type A connector is used to connect the cable from a USB device to
the Type A port on a computer or hub. The Type B connector is used to attach the USB cable to a USB device.

RJ-45 — The Registered Jack (RJ) physical interface is what connects the network cabling (CAT5) to the local extender and
remote extender. You may use either the T568A scheme (Table 5-1) or the T568B scheme (Table 5-2) for cable termination
because the extender uses all four pairs of the cable. RJ-45 connectors are sometimes also referred to as 8P8C connectors.
