5 Installing the VS-3232A in a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing in a rack How to Rack Mount
Before installing in a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing

CAUTION!!
When installing on a 19" rack, avoid hazards by taking
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (5 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the five holes in the
rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions

7 VS-3232A 32x32 Audio Matrix Switcher Configurations
The VS-3232A belongs to a series of 32x32 matrix switchers, including the
VS-3232V and the VS-3232Vxl, and as such, can interconnect with them. The
following sections describe:
The VS-3232A configuration setups (see section 7.1)
Various matrix configurations (see sections 7.2, 7.3, and 7.4)
The DIP-switch setup (see section 7.5)
How to connect a control interface (see section 7.6)
How to set the SYNC (see section 7.7)
How to control via the Ethernet (see section 7.8)
7.1 The VS-3232A Configuration Setups
The VS-3232A includes two configuration setups: the Follow-System setup
(see section 7.1.1) and the Master/Slave setup (see section 7.1.2).
7.1.1 The Follow-System Configuration Setup
The Follow-System configuration allows communication between the connected
units via a common control line.
In the Follow-System configuration setup:
Any type of signal can follow one or more signals within the setup at your
choice
Any unit can be turned ON or OFF at any time
The LCD display on each unit shows the switching operations
independently
Each unit within this configuration can be switched in the FOLLOW or
BREAKAWAY state (via the FOLLOW or BREAKAWAY front panel
buttons) at any time, depending on the current application requirements.
When the:
FOLLOW button is pressed, signals are switched simultaneously
BREAKAWAY button is pressed, each machine in the configuration setup
is switched independently
By default, the matrix switchers are set to the BREAKAWAY state (meaning
that each machine switches independently from the other machines in the
configuration setup).
Pressing the FOLLOW button on one machine and then on other machines,
sets them searching for other machines, and they can follow each other
without reference to the order in which they are connected. In this state,

VS-3232A 32x32 Audio Matrix Switcher Configurations
13
switching an input to an output on one machine, switches the same input to
the same output on the other machines in the FOLLOW state.
DIP 5 defines whether the VS-3232A unit can communicate with other
switchers via a common control line. Set DIP 5 to:
ON, to enable the Follow-System configuration setup
OFF, to disable the Follow-System configuration setup
Set the machine number on each machine to a different value.
The example illustrated in Figure 8 shows three 32x32 matrix switchers: one
composite video (CV) switcher (the VS-3232Vxl) and two VS-3232A audio
switchers (A1 for the “English” language, and A2 for the “French” language).
DIP 5 is set to ON and DIP 6 is set to OFF on all the switchers. Each unit
within the system is set to a different machine number (see section 7.5.1).

Figure 8: Connecting in the Follow-System Configuration Setup
The Follow-System configuration Setup lets you operate the system in the
following way:
Initially, all three units are set to the Breakaway state. This means that
each unit operates independently, as a standalone unit
Pressing the FOLLOW button on the two audio switchers, sets them
searching for other machines they can follow within the communication
line
At this state, the video switcher still operates as a standalone unit, but the
audio switchers follow each other: for example, switching input 1 to
output 16 on the English language audio switcher, switches input 1 to
input 16 on the French language audio switcher

KRAMER: SIMPLE CREATIVE TECHNOLOGY
VS-3232A 32x32 Audio Matrix Switcher Configurations
14
Pressing the FOLLOW button on the CV switcher too, sets it searching for
the other machines in the FOLLOW state
At this state, all three switchers follow each other: for example, switching
input 1 to output 16 on the English language audio switcher, switches
input 1 to output 16 on the French language audio switcher and on the CV
switcher. Alternatively, you switch the CV switcher and have both audio
switchers follow
To return to independent switching, simply press the BREAKAWAY
button on the switcher
7.1.2 The Master/Slave Configuration Setup
The Master/Slave configuration setup is only used for the multi-channel switchers
configuration: one unit is set to be the Master and the other units are set to be the
Slaves. The Slave units always follow the Master, they cannot be set to work as a
standalone, unless you turn them off and change the DIP-switch settings.
In the Master/Slave configuration setup, the Slave unit initializing-sequence
always follows the Master unit initialization-sequence, and the entire setup
sequence is automatic (the Master–slave system automatically sets the master
and the slave setup follows).
If several slave units are connected in a Master/Slave configuration, the
initialization delay time for each of the Slave units (except for the first slave in
the sequence) should be programmed via the menu, as described in section
9.7.
To change the initializing sequence delay time for a Slave unit via the menu,
set DIP 6 to OFF and turn the unit ON separately in the Master mode.
On the Slave VS-3232A unit, the LCD display
1
, shows the following message
upon initialization

The BREAKAWAY and FOLLOW front panel buttons have no effect in the
Master/Slave configuration setup since the connected machines act as one unit
in one box.
DIP 6 determines the operation mode of each unit within the Master/Slave
configuration setup. DIP 6 is set to:
ON, for the Slave units in the configuration setup
OFF, for the Master unit in the configuration setup
Set the machine number on all the machines to the same value.
The example illustrated in Figure 9 shows three 32x32 matrix switchers: one
composite video switcher and two audio switchers. DIP 5 is set to OFF on all
three switchers and DIP 6 is set to OFF on the CV VS-3232Vxl switcher (the
Master) and to ON on the two VS-3232A audio switchers

(the Slaves). All
the units have the same machine number (see section 7.5.1).

Figure 9: Connecting in the Master/Slave Configuration Setup
In this example, the Slaves always follow the Master, and both machines act
as a single unit.
Switching input 1 to output 16 on the CV switcher, switches input 1 to output
16 on the English language audio switcher and on the French language audio
switcher. In this state you cannot perform this switching operation on any of
the audio switchers and have the CV switcher follow, or set any of the
machines in this configuration to operate independently (as a standalone unit),
unless you turn OFF the machines and change the DIP-switch settings.

The example illustrated in Figure 10 shows three 32x32 matrix switchers: one
composite video switcher and two audio switchers. DIP 5 is set to ON on all
the units. DIP 6 is set to OFF on the CV VS-3232Vxl switcher and on the A1

Figure 10: The Follow-System Combined with the Master/Slave Configuration Setup
In this example, the audio switchers are in the Master/Slave configuration
setup (the French language switcher always follows the English language
switcher). The CV switcher and the combined audio switcher unit are in the
Follow-System configuration setup.
Table 4 summarizes the differences between the Follow-System configuration
setup and the Master/Slave configuration setup:

Several units are connected in a common control line.
The unit can be switched in the FOLLOW or
BREAKAWAY state at any time (using the FOLLOW
and BREAKAWAY front panel buttons), depending on
the current application requirements.
One unit is set as the Master, the others as slaves.
The Slaves always follow the Master. The machines
cannot operate as standalone units without turning
off and changing the DIP-switch settings.
The FOLLOW/BREAKAWAY state is not applicable
because the connected machines act as one unit.
Any unit can be turned on or off at any time. The Slave unit can be turned ON only after full
initialization of the Master unit.
Each machine has a different machine number value. All the machines have the same machine number.
