Introduction

The Black Box ServShare II provides a exible method for

allowing two or more users to share resources. Depending how

it is connected, the ServShare II can be used to drive up to four

video displays (video splitting), allow up to four users to access

a KVM switch (resource sharing) or, in conjunction with other

similar units and KVM switches, provide the opportunity for

many users to connect with many different systems (square

matrix).

ServShare II supports a wide 280MHz bandwidth that can

support very high screen resolutions of 1600 x 1280 and even

1900 x 1440 (with standard cables). When long cable runs (of

up to 30m) are required, ServShare II features a video boost

option to ensure that picture quality remains crisp.

Thanks to smart power control, the use of the supplied external

power supply is optional for most applications. This can be

handy when spare power sockets are not close at hand.

ServShare II uses standard connectors throughout for quick and

easy connection to host systems and peripherals alike.

One host or many

ServShare II can just as easily connect to a single

host system or, via a KVM switch, to many

systems.

Up to four users served on a rst come basis

Up to four users can simultaneously view the output from the host system. Any of the users

can take control of the host, providing it is not being used by one of the others. A user

relinquishes control two seconds after their last key push or mouse movement.

Main KVM connection

Power is optional

ServShare II is supplied with

a power supply, however, its

use is optional because power

can also be derived from the

keyboard connection of the

host system.

Typical ServShare II applications

The exibility and adaptability of the ServShare II becomes clear when you see

some of its typical uses.

Video splitter

A quick and easy

way to distribute

high quality

video to multiple

locations. The

internal video

boost feature

assists when

making long

cable runs to

remote monitors.

Resource sharer/contender

Allows common resources to

be shared between up to four

users. Typical applications include

general server management

from different desks; trading

oor systems where shared

information is vital.

Square matrix

This application permits multiple

users simultaneous access to any

systems. A clever arrangement

of ServShare II and suitable KVM

switches, such as the ServSwitch

Quadro, ensures sufcient

redundancy that everyone can

access a system of their choice.

The ServShare II units communicate

with the ServSwitch Quadro boxes

to indicate clearly to a user when a

particular system is already in use.

Each ServShare II connects to

both ServSwitch Quadro units

Installation and Operation

Mounting

ServShare II offers two main mounting methods:

• Supplied four self-adhesive rubber feet

• Optional rack mount assembly to hold up to eight 4-port ServShare II units

or up to sixteen 2-port ServShare II units.

Connections

Installation of the ServShare II involves a number of basic connections to some or

all of the following items:

• Host computer or KVM switch

• Keyboards, video monitors and mice

• Power supply (use is optional)

Cable lengths

The ServShare II uses high quality powered circuitry to prevent signal

degradation. When used in conjunction with the accompanying power supply,

this means that you can use relatively long cable links between the ServShare II,

the system and the user console or KVM switch. The lengths of cables that can

be used for given situations are summarized below.

Video resolutions of up to 1600 x 1280 are supported on longer cable lengths

while higher resolutions of up to 1900 x 1440 may be used with shorter links.

The ServShare II also features a video boost feature to ensure that picture quality

remains sharp over longer distances. See Conguration switches - Video

signal boost (switch 2) for more information.

Cable position Used without Used with

power supply power supply

ServShare II to Console 6.5ft (2m)* 32ft (10m)**

ServShare II to System 6.5ft (2m) 65ft (20m)**

Note: The total cable length (from system through to console) should not exceed 98ft (30m).

* Cable lengths can be increased to 16ft (5m) when used in square matrix formation (in conjunction

with KVM switches).

** For video only applications (i.e. without keyboard or mouse), any ‘video only’ link cable may be

up to 98ft (30m) long provided the overall cable run (i.e. including the cable on the other side of the

ServShare II) does not exceed 105ft (32m).

Host computer or KVM switch

The ServShare II can either connect directly to a single host computer or to range

of hosts via one or more KVM switches.

To connect a host computer or KVM switch

1 Ensure that power is disconnected from the computer or KVM switch 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 Connect the plugs at one end of a PS/2 cable set to the keyboard, video and

mouse sockets of the computer or KVM switch.

Monitor (video) Blue

Keyboard Purple

Mouse or Mid green

3 Connect the plugs at the other end of the PS/2 cable set to the corresponding

sockets, collectively labelled as ‘COMPUTER’, on the front panel of the

ServShare II.

Keyboards, video monitors and mice

The rear panel provides sets of ports (either two or four, depending on the

ServShare II model) and each accommodates a keyboard, video monitor and

mouse connection.

The ports can be connected and used in any order (see note 2 below), and not

all connectors of each port need to be used. For instance, when ServShare II is

used as a video splitter, usually only the video connections are utilized.

Where a user will be situated close to the ServShare II, the keyboard, video

monitor and mouse can be connected directly. When a user will be placed some

distance away, then an extender cable should be used. See What you may

additionally need for part numbers.

Note 1: In square matrix congurations, these rear panel ports would be

connected to the CPU/computer ports of suitable KVM switches.

Note 2: At power on, ServShare II attempts to gain information about the

capabilities of connected monitors (using the Display Data Channel [DDC]

format) by interrogating the monitor at port 1. If you are using a mixture of

monitors, it is advantageous to place one that supports DDC at port 1.

To connect a keyboard, video monitor and mouse

1 Position a suitable keyboard, video monitor and mouse in the required

location. Where the distance to the ServShare II is greater than the cable

lengths use suitable extender cables (see What you may additionally need).

2 Connect the keyboard, video monitor and mouse plugs to the sockets

of one of the ports (labelled between 1 and 4) at the rear panel of the

ServShare II.

Power supply (use is optional)

The ServShare II is supplied with a power supply and an appropriate country-

specic IEC power cord. There is no on/off switch so operation begins as soon as

the power supply is connected.

The use of the power supply is optional because the ServShare II can also derive

its power from the keyboard port of the host system or KVM switch. Where

up to four standard keyboards and mice are connected to the ServShare II (and

standard length cables are used), it is usually possible to power the ServShare II

purely from the host system or KVM switch. See opposite for more information.

IMPORTANT: If the power supply will NOT be used, click switch 1 on the front

panel down to its ON position. See Conguration switches - Power source

selection (switch 1) for more information).

To connect the power supply

1 Connect the low voltage output connector from the power supply unit to

the power socket on the front panel of the ServShare II.

Indoor use only

2 Connect the IEC connector of the supplied country-specic power cord to

the socket of the power supply.

3 Connect the power cord to a nearby main supply socket.

Do I need to use the power supply?

Thanks to smart power control, the use of the supplied external power supply

is optional for most applications because the ServShare II can be congured to

derive its power from the host system.

The following two main factors will determine whether you can use the

ServShare II with, or without the power supply:

1: Lengths of cables to host computer and to consoles

A All cables 6.5ft (2m) or less Power supply not required

B Any cables 7ft (2.2m) or more Power supply required

2: Power required by all connected keyboards and mice

A Total requirement is 400mA or less* Power supply not required

B Total requirement is 420mA or more* Power supply required

If either of the above factors meet the B scenario, then you need to use the

power supply.

* How to check power requirements

You can determine the overall power required by the connected keyboard and

mice by consulting their product labels. On the underside of almost all keyboard

and mice will be a label stating their power requirements.

This gure is usually represented as a voltage (e.g. 5V) and a current (e.g.

20mA).

• Most standard keyboards require around 50mA

• Most standard mice require around 20 - 25mA.

Add up the total current requirements for all connected devices. If the total

value is 400mA or less then you do not need to use the power supply (subject to

the cable lengths being 6.5ft (2m) or shorter).

Operation

User arbitration and keyboard indicators

During operation, all of the connected video monitors continuously receive the

output from the host system (or KVM switch). Control of the host system is

arbitrated by the ServShare II on a rst come, rst served basis. In the idle state,

control is available to all users and their keyboard indicators all show the current

Num Lock, etc. conditions of the host system.

At the moment that a key

is pressed or a mouse is

moved, the keyboards and

mice of the other users are

temporarily locked-out (the

video images remain). The

keyboard indicators of the

locked-out users then begin

to ash to conrm their

status:

After two seconds of inactivity from the user currently in control, the ServShare

II returns to its idle condition and the re-instates the keyboard indicators of the

locked-out users.

ServShare II indicators

The red indicators on the front panel of the

ServShare II illuminate to show which user

currently has control.

The green indicator illuminates when the

power supply is connected and switched on.

1234PWR

Video boost feature

The ServShare II offers a video boost feature which provides amplication to

compensate for losses introduced by long video cables. The effect of this is

to ensure that the video images remain sharp even at high resolutions over

relatively long distances.

To enable video boost

• Click switch 2 (ServShare II may be powered on or off) down into its ON

position.

Resetting ServShare II

In rare situations where ServShare II may produce erratic or incorrect operation,

a reset option is provided.

To reset the ServShare II

• Momentarily click switch 3 down into its ON position and then back up to its

OFF state.
