Overview
Because the CE-250 KVM Extender System 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 CE-250 System is also useful for control and security purposes,
where you can have the system unit in a secure area at the same time
that you put the console in a location that offers convenient access.
The CE-250 KVM Extender provides the ideal means to access the
remote system box, since it improves on previous designs by using
inexpensive Category 5 cable - the kind commonly used in Ethernet
networks - instead of bulkier, more expensive, standard cables.
Category 5 cabling makes for a much neater, more convenient, more
reliable data transfer connection.
The CE-250 features a custom ASIC to ensure the utmost in reliability
and compatibility, and can also sense the distance to the system and
automatically adjust the gain to compensate.
Setup is as easy as can be - simply connect the computer system box
and local console to the Local CE-250 Module; run the Cat. 5 cable to
the Remote CE-250 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 the CE-250 with a KVM switch.

Computers
The following equipment must be installed on each computer that is to
be connected to the system:
With PS/2 Type Connectors:
M
M A VGA, SVGA or Multisync card.
M A 6-pin mini-DIN mouse port
M A 6-pin mini-DIN keyboard port
With AT Type Connectors:
M
M A VGA, SVGA or Multisync card.
M A DB-9 (standard serial), mouse port plus mouse adapter (part #
2A-105).*
M A 5-pin DIN (standard AT), keyboard port plus keyboard adapter
(part # 2A-106).*
* Not included - requires separate purchase.
Cables
Although it is possible to use standard KVM cables to link computers
M
with PS/2 type keyboard and mouse ports to the CE-250L, for
optimum signal integrity and to simplify the layout, we strongly
recommend that you use the high quality CS Custom KVM Cable
that is provided with this package.
It is not possible to use standard KVM cables to link computers with
M
AT type keyboard and mouse ports to the CE-250L. For those
computers, CS Custom KVM Cables must be used.
Category 5 cable is the minimum required to connect the local and
M
remote CE-250 units. Cable of a lesser standard will result in
degrading the video signal. For best performance, we strongly
recommend Category 5 cable.

Installation
Setting up the KVM Extender System is simply a matter of plugging in
the cables:
1. Make sure that all the equipment to be connected up is powered Off.
2. Plug the cables from the local console devices (mouse, keyboard,
monitor), into their ports on the Console side of the Local Unit
(CE-250L).
3. Plug the appropriate connectors on the KVM cable supplied with this
unit into the CPU side of the CE-250L. Each connector is marked
with an appropriate icon to indicate which it is.
Note: The female monitor connector is the one that plugs into the
CE-250L.
4. Plug the connectors on the other end of the 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 appropriate icon to indicate which it is.
5. Plug either end of the Category 5 twisted pair cable into the
CE-250L’s Remote I/O port.
6. Plug one of the power adapters (supplied with this package) into an
AC source; plug the adapter’s power cable into the CE-250L’s
Power Jack
7. Plug the other end of the Category 5 twisted pair cable into the I/O
port of the Remote Unit (CE-250R).
8. Plug the cables from the remote console devices (mouse, keyboard,
monitor), into their ports on the Console side of the CE-250R.
9. Plug the second power adapter (supplied with this package) into an
AC source; plug the adapter’s power cable into the CE-250R’s
Power Jack.
