OVERVIEW

The CE-252R/L offers local and remote access to your KVM

installation. Both (local and remote) KVM extenders support

PS/2 consoles and can be located up to 300 m (1000 feet) apart.

You can reliably manage a large number of computers via a KVM

switch. Additional computers can also be connected to the

remote KVM extender.

The CE-252R/L also features Automatic Gain Control, which

compensates signal strength as the distance between the local

and remote KVM extenders varies (over Cat 5 cables). This

translates into high resolution video (up to 2048 x 1536) at a

lower cost.

The CE-252R/L uses a custom ASIC to ensure the utmost

reliability and compatibility. This technology comprises automatic

distance sensing and signal strength (gain) adjustment.

Setup is easy - simply connect the computer system box (or KVM

switch) and Local Console to the CE-252 Local Unit; run a Cat. 5

cable to the CE-252 Remote Unit (up to 300 meters away); finally

plug the Remote Console into the Remote Unit.

highest resolution that you will be using on any computer in

the installation

Two PS/2 style keyboards

Two PS/2 style mice

Cables

Although it is possible to use standard KVM cables to link

computers with PS/2 type keyboard and mouse ports to the

CE-252R/L, for optimal signal integrity ATEN recommends

using the KVM Cables provided with this package.

For best performance, use Category 5 (or better) cables to

cables. Refer to the installation diagram on the following page

(the numbers in the diagram correspond to the numbered steps)

and do the following:

1. Connect the local console devices (mouse, keyboard and

monitor) to the ports on the rear of the Local Unit (CE-252L).

2. Plug the provided KVM cable into the appropriate connector

on the front of the CE-252L, then plug the connectors on the

other end of the KVM cable into the appropriate ports on the

computer system (or Console section of the KVM switch - if

you are using one).

Each connector is marked with an identifying icon.

3. Connect one end of a Category 5 twisted pair cable to the

Remote I/O port on the CE-252L, then plug the other end of

the Category 5 twisted pair cable into the Remote I/O port on

the CE-252R.

4. Connect one of the provided power adapters into an AC

source, then connect the adapter's power cable to the Power

Jack on the rear of the CE-252L.

1. Ensure that all equipment to be connected is pow-

ered off.

2. Make sure that all devices you will be connecting up

are properly grounded.

3. Unplug the power cords of any computers that have
