Introduction
The CCS4-USB (Command and Control Switch, four port, USB) is a 
compact unit created to allow a single operator to access information 
and control operations across numerous systems and screens. With 
the CCS4-USB switch, you can use a single USB keyboard and USB 
mouse to fulfil functions that previously required four separate sets.\
 
This provides immediate savings in both desk space and also the time 
required to access and control up to four systems and screens. The 
CCS4-USB features our True Emulation technology, which ensures 
that the full characteristics of the connected USB keyboard and mouse 
are passed to every system. 
In addition to switching the keyboard and mouse, the CCS4-USB can 
also share a set of speakers and two separate USB peripherals between 
the four systems. This can be done either in concert with the keyboard 
and mouse (and each other) or totally independently.
The CCS4-USB switch can be used in combination with various Adder 
extender products (such as AdderLink Infinity, X50 and X-DVIPRO) 
to extend the distance between the user and the computers under 
control.  
Switching between the systems connected to the CCS4-USB can be 
achieved in five different ways:
•	 The	innovative	Free-Flow automatic switching utility, 
•	 The	COMPUTER	button	on	the	top	panel,
•	 Keyboard	hotkey	combinations,
•	 Mouse	button	combinations,
•	 The	optional	remote	control	selector.							
Where additional feedback is required as to which systems and screens 
are selected at any time, the optional CCS-XB kit provides discreet 
stick-on	LED	monitor	indicators.	When	a	system/screen	is	selected,	a	
corresponding	LED	monitor	indicator	illuminates	(in	a	choice	of	colours)	
to confirm the action.

The optional remote control allows the CCS4-USB switch to be neatly concealed amongst the cabling.
The keyboard/mouse, the speakers and two individual USB channels can be collectively or separately switched through to each PC system. These are electronically switched to the required system using any of five methods: Free-Flow utility, CCS4-USB switch control panel, keyboard key-presses, mouse buttons or optional remote control.

The video displays are connected directly to their respective systems as\
 usual. A single USB link (plus an optional speaker connection) is made between each system and \
the CCS4-USB switch.

What is Free-Flow?
The	Adder	Free-Flow	represents	true	innovation	in	KVM	switching.	For	the	first	
time, Free-Flow allows users to automatically switch between target comp\
uters 
simply by moving the mouse pointer from screen to screen. What makes thi\
s 
such a revolution is that you no longer need software to be installed on\
 your 
mission critical computers in order to do this. Adder Free-Flow resides \
on the 
switch itself, sensing screen boundaries and instantaneously switching k\
eyboard 
and mouse to the defined target computer. Free-Flow can be configure\
d for 
almost any combination of screens using the included application which a\
llows 
you to declare the individual screen sizes and visually position each on\
e relative 
to the others.
Free-Flow consists of special code within the CCS4-USB switch plus an in\
tuitive 
graphical configuration application. First you inform the Free-Flow co\
nfiguration 
application how many screens you have, their pixel resolutions and how t\
hey are 
physically arranged (e.g side-by-side, vertical stack, square formation\
, etc.). You 
then download this information to the CCS4-USB switch and this is used d\
uring 
operation	to	determine	the	precise	moment	to	switch	from	one	screen/system	to	
the next.
The beauty of Free-Flow is its simplicity of configuration and operati\
on. Once 
the initial configuration has taken place, all monitoring and switchin\
g is handled 
within the CCS4-USB without need for extra connections or software utili\
ties.
Issues when using Free-Flow
•	 The	CCS4-USB	switch	must	have	a	minimum	of	firmware	version	2.00	
installed to operate with Free-Flow. See Performing upgrades for details.
•	 When	computers	and	their	displays	are	not	currently	selected,	the	CCS4-
USB ‘parks’ their mouse pointers in the bottom right corner of the\
 screen. 
In most cases this will cause no issues, however, it may be noticeable i\
n 
circumstances such as the following: 
•	 If	the	task	bar	is	set	to	auto	hide	and	it	is	positioned	either	along	the	
bottom of the screen (as default) or along the right hand side, then t\
he 
task bar will automatically reappear when the mouse pointer is parked. 
•	 When	playing	full	screen	video,	the	on-screen	controls	(play,	pause,	seek	
etc.) will very likely be revealed when the mouse pointer is parked. 
•	 To	cure	the	either	of	the	above	issues,	it	is	possible	to	alter	the	mouse 
parking position.  
•	 The	mouse	will	not	flow	across	the	screens	while	any	mouse	buttons	are	
pressed down - this prevents undesired behaviour when dragging windows 
around or group-selecting items.
•	 By	default,	Linux	operating	systems	use	relative	mouse	data	which	Free-
Flow cannot use. A ‘udev rule’ is available that allows Linux to u\
se absolute 
mouse	positioning,	thus	enabling	standard	Free-Flow	(not	Multi-Monitor	
mode) to operate.
•	 Multi-Monitor	Free-Flow	is	for	use	with	the	Windows	operating	system	only	
and requires specialist driver to be installed on each PC. See Multi-Monitor 
Free-Flow configuration for details.

Free-Flow now also supports multiple monitors on each PC (drivers are required).

What is True Emulation?
True	Emulation	represents	a	significant	breakthrough	in	sharing	USB	devices	
between two or more computer systems. Until this point, the problem has \
been 
how to create a USB switch that provides all of the following:
•	 Quick,	transparent	and	reliable	switching,
•	 Accurate	representation	of	the	connected	USB	keyboard	and	mouse,	
•	 Switching	control	via	the	connected	USB	keyboard	and/or	mouse.
The difficulty in achieving all of the above requirements has been due\
 to the 
complexity of the USB standard. This has led to various problems that ha\
ve 
spawned a number of possible solutions.  
Enumerated USB switching
The earliest attempts to switch USB devices applied a relatively ‘han\
ds off’ 
approach.	Enumerated	USB	switches	are	the	electronic	equivalent	of	those	old	
mechanical	KVM	switches	with	a	large	knob	on	the	front.	
Enumerated	switches	are	so	called	because	a	connected	USB	device	will	be	
required to perform a full initiation (a process called Enumeration) every time it is 
switched; just as if you had pulled out the plug and then reconnected it\
. 
Enumerated	switches	simply	pass	all	signals	straight	through	between	the	USB	
device and the computer, they do not attempt to interpret any data. For \
most 
devices, this offers an advantage because the switch just leaves them to\
 get on 
with their jobs without any interference or any hit on performance. Howe\
ver, it 
means that a USB keyboard or mouse cannot be used to control the switchi\
ng 
process - a quick and simple control method expected by most users. Reli\
ability 
of switching is also an issue that has plagued enumerated switches, espe\
cially 
when used with certain USB devices and particular operating systems. 
Emulated USB switching
The issues with interpreting the complex USB data streams and recreating\
 (or 
Emulating) the identity of attached USB devices were eventually solved, leading \
to	the	creation	of	the	Emulated	USB	switch.	
A neat side effect of the technique used is that each computer can be fo\
oled 
into thinking that the USB device is permanently connected to it, even w\
hen 
the device is switched to another computer. This means that the enumerat\
ion 
process for the USB device takes place only once, during the first pow\
er 
on. After that, a computer merely sees a dormant version of the USB devi\
ce 
whenever the device is actually connected to a different computer.    
However, it remains a complex task to dynamically assume the identity of\
 a USB 
device, distribute it among the connected computers and maintain all of \
the 
necessary signals, states and processes. Therefore, manufacturers have previously 
relied upon a fixed keyboard and mouse profile that is declared to e\
ach 
computer, regardless of the actual connected devices. This precluded the\
 use of 
any special keyboard or mouse features over and above the standard layou\
ts. 
True Emulation 
Mindful	of	the	limitations	associated	with	the	
previous USB switching techniques, we set about 
creating a more effective and elegant solution. 
After a great deal of research and development, 
True Emulation is the result.
True	Emulation	allows	the	complete	identity	of	
the keyboard and mouse to be copied and then 
presented to all of the connected computers. 
This means that any keyboard offering specialist 
function keys or any mouse with extra features 
will be fully supported at each computer. As with 
the previous emulation method, the unselected 
computers will continue to see the identities 
of the keyboard and mouse, which means that 
no enumeration is necessary when their link 
becomes active once again. This not only helps 
to speed up the rate of reconnection, but also 
raises the reliability of switching because USB 
links are at their most vulnerable during the 
enumeration process.
True	Emulation	relies	upon	a	high	speed	circuit,	
called	an	Emulation	Engine,	to	fully	emulate	
the USB device identities and also interpret 
keyboard and mouse data streams. The result is 
full	support	for	KVM	switching	control	via	hotkey	
presses	or	the	third	button/scroll	wheel	of	a	
mouse.   
True	Emulation	is	not	necessarily	required	by	
other USB devices, which is why you will also 
find two enumerated circuits included (shown in 
green	within	the	block	diagram)	alongside	the	True	Emulation	feature	(shown	
in blue). This allows those other USB devices to operate at their highe\
st speeds, 
without any intervention. The enumerated circuits benefit greatly from\
 the 
USB	Hubs	that	are	jointly	used	with	the	True	Emulation	system.	Because	they	
interface directly and permanently with each computer, they help to stab\
ilise the 
dormant links, making errors during enumeration much less likely.
The	dual	switching	arrangement	provides	further	flexibility	because	the	True	
Emulation	and	enumerated	sections	can	be	switched	in	unison	or	independently	
of each other, as required. Thus, your various peripherals can operate w\
ith 
different computers at the same time. Please see software release notes \
for a list 
of supported products.
