1.0 System Description

The Lantronix 2-Port KVM (300.000.4000) is a Keyboard, Mouse and Video

switching system for one user and two PS/2-equipped computers.

2-Port KVM, Front View

1.1 System Features

• Control two computers with one Keyboard, Mouse and Monitor

• Emulates PS/2 Keyboard in the event of power interruption

• Front panel pushbutton controls AND keyboard control

• Front panel LEDs show connection status and power

2.0 Installation

The KVM 2-Port is connected in between two computers (or servers) and one

user station, consisting of a PS/2-type keyboard, PS/2-type mouse or trackball

device, and a video monitor. It must be placed within limited cable distances of

these components, but is generally placed on a shelf or in a 19-inch EIA

equipment rack near the computer equipment. The KVM 2-port requires one AC

power connection (an IEC-type power cordset is provided with the unit).

All connections are made with industry-standard mouse, keyboard and video

connectors found in conventional PC computer equipment. The necessary PS/2

and Video cables are ordered and shipped with the KVM 2-Port.

2-Port KVM User Guide Lantronix Inc.

The KVM 2-port unit has two pushbuttons and several LEDs on its front panel.

The user will press the pushbuttons to switch from one server to the other. The

User may also switch from server to server using keyboard commands, and need

not press the front panel buttons to operate the unit.

There are no user-servicable parts inside the unit. A protective power fuse is

located in the power entry module, accessible from the rear of the unit. The fuse

should never need replacement during normal operation or usage.

2.1 System Features

• PS/2-type connections for Keyboard and Mouse

• HD-15 connectors for Video Monitors

• Independent of computer platform and OS

• Silent operation, suitable for placement near personnel

• Class A compliant device

2.2 Hardware Features

• AC powered using a single universal AC power inlet (with IEC cordset)

• One User position for a Keyboard, Mouse and HD15 Video Connection

• Two Computer positions (A & B) for Keyboard, Mouse and HD15 Video

connection inputs

• Keyboard connections are emulated to maintain proper signals between

the two computers; keyboard emulation is maintained even if the 2-Port

KVM loses power

• Low power usage and silent operation. Unit is convection cooled and

requires no special environmental considerations

2.3 Mounting Instructions

The 2-port KVM is in a metal enclosure and may be placed on a shelf, or rack-

mounted in a conventional EIA-type 19-inch rack. Removable rack mount

brackets are included with the unit. You must provide rack mount screws for your

rack assembly.

All connections are made to the rear of the unit, and the Power Switch is on the

rear of the unit.

If placing the unit on a shelf or desktop, install the four rubber feet included with

the unit to protect the desk surface.
