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 CE250A is also useful for control and security purposes, si nce 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 CE250A 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 us ed 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 CE250A 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 CE250A module, run the Cat 5 cable to the Remo te
CE250A module (up to 150 meters away); and plug the remote console into the
Remote Module.
Note: You can control numerous remote systems from a single console by
combining th e CE250A with a KVM switch.

Rack Mounting
For convenience and flexibility, the CE250AL and CE250AR can be mounted on
system racks. To rack mount a unit do th e following:
1. Unscrew either the two front screws or two rear screws from the bottom
panel.
1. Important safety information regarding the placement of this
device is provided on page 17. Please review it before
proceeding.
2. Make sure that power to all the devices you will be installing has
been turned off. You must unplug the power cords of any
computers that have the Keyb oard Power On function.

Installation
Grounding
To prevent damage to your installatio n it is important that all devices are
properly grounded.
1. Use a grounding wire to ground 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 CE250AL connects to and the monitor
that the CE250AR connects to are properly grounded.
3. See the Grounding Information card that came with this package for
proper grounding details.

(Continued from previous page.)
4. For increased groundi ng protecti on, 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 th e RJ-45 socket as
shown in the diagram below:
Chapter 2. Hardware Setup
13
Connecting Up
Refer to the installation diagram on the follow ing page (the numbers in the
diagram correspond to the numbers of the steps), as you perform these steps:
1. Plug the cables from the local console devices (keyboard, monitor,
mouse), into th ei r ports on the rear panel of the Local Unit (CE250AL).
2. Plug the SPHD end of the KVM cable supplied with this unit into the
KVM port on the front panel of the CE250AL.
Note: The shape and function of the connectors on the cable and KVM
switch have been modified so that onl y KVM cables design ed to
work with this sw itch can be used.
3. Plug the connectors on the other end of the cable into the appropriate ports
on the computer (or Console section of the KVM switch - if you are using
one). Each connector is marked with an appropriate icon to indicate itself.
4. Plug one end of a Cat 5 or higher STP cable into the CE250AL's Remote I/
O port. Plug the other end of the cable into the CE250AR’s Remote I/O
port.
Note: STP cable is not supplied with this package. It requires a separate
purchase. The cabl e can be up to 150 m (500 ft) long.
5. Plug the cables from the remote console devices (keybo ard, monitor, and
mouse), into their ports on the Console side of the CE250AR.
6. Plug the power adapter (supplied with this package) into an AC source;
plug the adapter's power cable into the Remote Unit’s (CE250AR's) Power
Jack.
7. If you choose to use a power adapter with the CE250AL, plug the power
adapter into an AC source; plug the adapter's power cable into the
CE250AL's Power Jack.
Note: Use of a power adapter with the CE250AL is optional. Refer to the
note regarding the power jack on page 7 for details.

Operating Modes
The CE250A KVM Extender has two operating modes: Local and Remote, as
described in the table below :
Mode Selection
The Operating Mode Selection Switch, located on the CE250AL’s front panel,
controls the operating mode of the CE250A KVM Extender system. Pressing
the switch toggles the system between Local and Local / Remote operating
modes.
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.
