Introduction

Overview

The CE250A KVM Extender allows access to a computer system from a remote console (keyboard, monitor, and mouse). It is perfect for factory and construction sites, or any type of installation where the console needs to be in a conveniently accessible location, but you want the system equipment to reside in a safe place – away from dust, dirt, and harsh environmental influences.

The CE250

A is also useful for control and security purposes, since you can

store the system unit in a secure area at the same time that you put the console in a location that offers convenient access.

The CE250

A KVM Extender provides the ideal means to access the remote

system box, since it improves on previous designs by using compact, inexpensive Cat 5 cable – the kind commonly used in Ethernet networks – instead of bulkier, more expensive, standard cables. Cat 5 makes for a much neater, more convenient, more reliable data transfer connection.

A key feature of the CE250

A is built-in 8KV ESD protection and 2KV surge

protection. It also features a custom ASIC that ensures the utmost in reliability and compatibility. It senses the distance to the system and automatically adjusts the gain to compensate.

Setup is as easy as can be – simply connect the computer system box and local console to the Local CE250 CE250

A module (up to 150 meters away); and plug the remote console into the

A module, run the Cat 5 cable to the Remote

Remote Module.

Note: You can control numerous remote systems from a single console by

combining the CE250A with a KVM switch.

Chapter 2. Hardware Setup

Installation

Grounding

To prevent damage to your installation it is important that all devices are properly grounded.

1. Use the two grounding wires supplied with this package to grou nd both

units by connecting one end of the wire to the grounding terminal, and the other end of the wire to a suitable grounded object.

2. Make sure that the computer that the CE250

that the CE250

AR connects to are properly grounded.

(Continued from previous page.)

4. For increased grounding protection, use STP (shielded twisted pair) cable to connect the local and remote units. There are two methods that can be used:

a) In addition to the eight paired wires, STP cable also contains a

grounding wire. Solder this wire to the RJ-45 connector as shown in the diagram below:

b) The second method is to use the STP cable shielding for grounding. In

this case, make sure that the shielding makes tight contact with the top inside of the RJ-45 connector as shown in the diagram below:

In either case, make sure that the sides of the RJ-45 connector make tight contact with the grounding contacts on the sides of the RJ-45 socket as shown in the diagram below:

Note: STP cable is not supplied with this package. It requires a separate

purchase. The cable can be up to 150 m (500 ft) long.

5. Plug the cables from the remote console devices (keyboard, monitor, and

mouse), into their ports on the Console side of the CE250

AR.

6. Plug the power adapter (supplied with this package) into an AC source;

plug the adapter's power cable into the Remote Unit’s (CE250

AR's) Power

Jack.

7. If you choose to use a power adapter with the CE250

AL, plug the power

adapter into an AC source; plug the adapter's power cable into the CE250

Operation

Operating Modes

The CE250A KVM Extender has two operating modes: Local and Remote, as described in the table below:

Mode Description

Local Only the local console has KVM (keyboard, video, mouse)

access. The remote console’s monitor is blank, and the remote console’s keyboard and mouse input is disabled.

Local / Remote Both the local and remote consoles can have KVM access.

However, they cannot both have access at the same time. The console without access has to wait until the console with access stops inputting data before it can gain access.

Mode Selection

The Operating Mode Selection Switch, located on the CE250AL’s front panel, controls the operating mode of the CE250 the switch toggles the system between Local and Local / Remote operating modes.

Safety Instructions

General

 Read all of these instructions. Save them for future reference.  Follow all warnings and instructions marked on the device.  Do not place the device on any unstable surface (cart, stand, table, etc.). If

the device falls, serious damage will result.

 Do not use the device near water.  Do not place the device near, or over, radiators or heat registers.  The device cabinet is provided with slots and openings to allow for

adequate ventilation. To ensure reliable operation, and to protect against overheating, these openings must never be blocked or covered.

 The device should never be placed on a soft surface (bed, sofa, rug, etc.) as

this will block its ventilation openings. Likewise, the device should not be placed in a built in enclosure unless adequate ventilation has been provided.

 Never spill liquid of any kind on the device.  Unplug the device from the wall outlet before cleaning. Do not use liquid

or aerosol cleaners. Use a damp cloth for cleaning.

 The device should be operated from the type of power source indicated on

the marking label. If you are not sure of the type of power available, consult your dealer or local power company.

 The device is designed for IT power distribution systems with 230V

phase-to-phase voltage.

 The device is equipped with a 3-wire grounding type plug. This is a safety

feature. If you are unable to insert the plug into the outlet, contact your electrician to replace your obsolete outlet. Do not attempt to defeat the purpose of the grounding-type plug. Always follow your local/national wiring codes.

 Do not allow anything to rest on the power cord or cables. Route the

power cord and cables so that they cannot be stepped on or tripped over.

 If an extension cord is used with this device make sure that the total of the

ampere ratings of all products used on this cord does not exceed the

Page 26

CE250A User Manual

extension cord ampere rating. Make sure that the total of all products plugged into the wall outlet does not exceed 15 amperes.

 T o help protect your system from sudden, transient increases and

decreases in electrical power, use a surge suppressor, line conditioner, or un-interruptible power supply (UPS).

 Position system cables and power cables carefully; Be sure that nothing

rests on any cables.

 Never push objects of any kind into or through cabinet slots. They may

touch dangerous voltage points or short out parts resulting in a risk of fire or electrical shock.

 Do not attempt to service the device yourself. Refer all servicing to

qualified service personnel.

 If the following conditions occur, unplug the device from the wall outlet

and bring it to qualified service personnel for repair.

 The power cord or plug has become damaged or frayed.  Liquid has been spilled into the device.  The device has been exposed to rain or water.  The device has been dropped, or the cabinet has been damaged.  The device exhibits a distinct change in performance, indicating a need for

service.

 The device does not operate normally when the operating instructions are

followed.

 Only adjust those controls that are covered in the operating instructions.

Improper adjustment of other controls may result in damage that will require extensive work by a qualified technician to repair.

 Do not connect the RJ-11 connector marked “UPGRADE” to a public

telecommunication network.
