5 Installing the VP-8x4 in a Rack
This section describes how to install the VP-8x4 in a rack.
Before Installing on a Rack How to Rack Mount
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5ºto +45ºC (41ºto 113ºF)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20ºto +70ºC (-4ºto 158ºF)
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 (3 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 four 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
(you can download it at:
http://www.kramerelectronics.com)

6.5.1 Setting the Delay
You can achieve clean transitions when switching between non-genlocked
sources by setting the delay time—ranging from 0 sec to 3.5 sec
1
—via the
DELAY DIP-switches, as Table 5 defines. The VP-8x4 unit is shipped (its
factory default state) with no delay, that is, the DELAY DIP-switches are set up
for a 0 sec delay. The delay time is the period where the output will be forced
to black when switching between inputs.

2.5 ON OFF ON
3.0 ON ON OFF
3.5 ON ON ON
6.5.2 Setting the Machine # DIP-switches
The Machine # determines the address of a VP-8x4 unit, specifying which
VP-8x4 unit is being controlled when several VP-8x4 units are connected to a
PC or serial controller. Set the Machine # on a VP-8x4 unit via MACH# DIPs
4, 5, 6 and 7, according to Table 6.
When using a standalone VP-8x4 unit, set the Machine # to 1. When
