Welcome

Introduction

Thank you for choosing the ServSwitch CX extender

set from Black Box. These compact modules allow

you to place the controlling keyboard, video

monitor and mouse up to 328 feet (100 metres)

from a computer system.

Two types of CX extender sets are avilable:

ACU5001A for PS/2-style keyboard and mouse

connections and ACU5002A for USB-style

connections. The long distance link between the

modules is made via Category 5, 5e or 6 twisted

pair cabling.

Special circuitry within the remote module allows

you to make adjustments to the sharpness and

brightness settings to suit your own preferences.

Installation & Operation

Connections

Installation of the ServSwitch CX extender set is straightforward and minimal

conﬁguration requirements in most cases. The moulded SAM (Server Access

Module) connects directly to the system, while the CX Remote module is at the

other end of the twisted pair cable and attaches to the keyboard, mouse, etc.

• Connections at the SAM (local) unit

• Connections at the X100 (remote) module

Cable length advice

The ServSwitch CX extender set supports twisted-pair structured cabling within

categories 5, 5e and 6. Of these three cable types, category 5 generally provides

the best transmission of video signals because its four pairs of conductors are

the most evenly twisted.

Category 5e and 6 cables use conductor pairs that are unevenly twisted in order

to combat interference effects encountered within higher frequency networks.

While these uneven twists work well for Ethernet signals, they can impose

problems for the video signals transceived by the CX extender modules. The

CX extender modules send the red, green and blue video signals on separate

twisted pairs within the cable. If any of the colour signals are made to travel

slightly further or shorter distances than the others, the result is seen as mis-

aligned colours on screen. This is called skew and becomes more noticeable as

cable runs become longer and screen resolutions/refresh rates increase.

As an approximate guide, you should expect the following maximum cable

lengths (achievable at resolutions up to 1600 x 1200 @ 60Hz):

Category 5 Category 5e or 6

100m ¹50 to 100m ¹

¹ length limited by skew in the cable.

Connections at the SAM (local) unit

1 Where possible ensure that power is disconnected from the system to be

connected.

(Note: If it is not possible to switch off devices prior to connection, then

a ‘Hot plug’ procedure is available – see the Hot plugging and mouse

restoration section for more details).

2 Locate the required SAM and attach its video, keyboard and mouse (PS/2-

style or USB) connectors to the relevant sockets on the computer system.

4 Attach the connector of the cable run to the socket of

the SAM. The other end of the cable run will attach to

the CX Remote module.

Connections at the CX Remote module

1 Place the CX Remote module adjacent to the remote user location.

2 Attach the video monitor, keyboard and mouse connectors to the sockets of

the CX Remote module.

3 Attach the connector of the cable run leading from the SAM to the

TO LOCAL socket of the CX Remote module.

nearby mains socket.

6 Where necessary, use the in-built video compensation feature to eliminate

any effects caused by the cable run. See Video compensation for details.

Note: When shipped, all switches are set in the OFF positions and this will

produce normal operation.

CX Remote module switches

Certain aspects of operation can be affected by the switches on the CX Remote

module.

Switch 1

OFF: Normal operation.

ON: (Before power is applied) Places the CX Remote module into ﬂash upgrade

mode so that the internal software can be changed. Please see the Flash

upgrade section in the ‘Special conﬁguration’ chapter.

Switches 2 and 3

Switches 2 and 3 determine which two keyboard keys (when pressed in unison)

are to be designated as ‘hotkeys’. Hotkeys signal to the CX Remote module that

the next key to be pressed is a special conﬁguration command for the module

and is not to be passed to the computer system.

2 OFF

3 OFF Hotkeys = CTRL and SHIFT

2 OFF

3 ON Hotkeys = ALT and SHIFT

2 ON

3 OFF Hotkeys = CTRL and ALT

Operation

General use

In use, the CX Remote modules should be transparent - the system and its

peripherals should operate exactly as normal, the only difference being that they

are now up to 100 metres apart.

In some installations, you may see some ‘shadows’ to the right of high contrast

screen characters. This can be caused by an incorrectly selected sharpness setting

and it may be necessary to make adjustments to correct this. Please see Video

compensation - sharpness and brightness in the ‘Special conﬁguration’

section.

Locking and unlocking the system

In situations where the computer system (and its local SAM) can be locked away

the CX Remote modules offer a viable security system to deter unauthorised use.

Once a password has been set, a simple key sequence allows the system to be

quickly and securely detached from its peripherals. Only the correct password

will reconnect the remote and local modules.

To lock the system

1 First set a password. For further details, please refer to the Password

setting section in the ‘Special conﬁguration’ chapter.

2 Simultaneously press the currently conﬁgured hotkeys (by default, and

) along with .

The screen will go blank and the three keyboard

indicators will begin alternately ﬂashing between the

‘Num Lock’ and ‘Scroll Lock’, and ‘Caps Lock’. This

sequence indicates that a password is required.

To unlock the system

1 Enter the correct password and press .

Note: Passwords are NOT case sensitive.

Note: If an invalid password has been entered and the keyboard indicators

are not ﬂashing as described above, press to clear the incorrect attempt.

2 If the correct password is entered, the screen will be restored and normal

operation can continue.

To enable the video

Simultaneously press the currently conﬁgured hotkeys (by default, and )

long with . This command will be required to restore the video if and

along with is used when no password has been set.

To disable the video

Simultaneously, press the currently conﬁgured hotkeys (by default, and )

along with .

Special conﬁguration

Conﬁguration

You can alter the way that the ServSwitch CX extender modules operate to suit

your requirements. This is done using the Conﬁguration mode and you can

affect the following settings:

• Password setting – allows you to lock the remote module to prevent

unauthorised system access.

• Mouse restoration and settings – allows you to restore mouse operation

and also to change the mouse type.

• Video compensation - sharpness & brightness – allows you to manually

adjust the video image to ensure that it is crisp and bright.

• Miscellaneous settings – report ﬁrmware version and restore settings.

What are hotkeys?

Hotkeys are two normal keyboard keys that, when pressed simultaneously with

a third key, signal to the modules that you are sending a message speciﬁcally to

them and not to the computer. The hotkeys are ordinarily and , while a

third keypress determines what you want the modules to do.

If the standard and hotkeys are also needed for computer tasks, you

can change them for another combination using switches 2 and 3 on the CX

Remote module:

2 OFF

3 OFF Hotkeys = and (default setting)

2 OFF

3 ON Hotkeys = and

2 ON

3 OFF Hotkeys = and

2 ON

3 ON Hotkeys disabled

Entering, using and exiting conﬁguration mode

To enter and use conﬁguration mode:

1 Simultaneously press the currently conﬁgured

hotkeys (by default, and ) along with .

The three keyboard indicators (‘Num Lock’, ‘Caps

Lock’ and ‘Scroll Lock’) will now begin to ﬂash in

sequence to show that you are in conﬁguration

mode.

2 Press the ﬁrst letter of the required conﬁguration

option, for instance .

All three keyboard indicators will illuminate

continuously.

3 Press the number of the required conﬁguration

option, for instance .

The ‘Scroll Lock’ indicator will extinguish, leaving

the ‘Num Lock’ and ‘Caps Lock’ indicators lit.

4 Press to conﬁrm your option.

The three keyboard indicators (‘Num Lock’, ‘Caps

Lock’ and ‘Scroll Lock’) will now begin to ﬂash in

sequence again.

To exit from conﬁguration mode:

1 Within conﬁguration mode, the three keyboard indicators should be ﬂashing

in sequence to show that the module is ready to receive a new command.

2 Press .

The three indicators will return to their normal states.
