Overview

3 Overview
The Kramer VM-1045 is a high performance distribution amplifier for
component video signals. The unit has four channels. Each channel includes
seven BNC connectors: an input, a looping output, and five outputs.
The VM-1045 can be configured as a 1x1:5 component RGB/S DA, a 2x1:5
s-Video (Y/C) DA or as a 4x1:5 composite video DA.
The channels can be interconnected via the looping outputs to form larger
configurations. Also, several VM-1045 machines can be cascaded via the
looping outputs.
In particular, the VM-1045:
Has a bandwidth of over 415MHz, ensuring transparent video
performance and supporting SDI signals (for example, a 4x1:5 SDI DA)
Features independent input signal termination, as well as level and EQ.
controls per channel
Achieving the best performance means:
Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
Avoiding interference from neighboring electrical appliances and
positioning your VM-1045 away from moisture, excessive sunlight and
dust

5 Installing the VM-1045 on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
5 to 65% RHL, non-condensing
-20 to +70 Deg. Centigrade
5 to 95% RHL, non-condensing
Operating humidity range
Storage temperature range
Storage humidity range
When installing on a 19" rack, avoid hazards by taking
care that:
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.
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.
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:
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)




In some models, the front panel
may feature built-in rack ears
Once rack mounted, enough air will still flow around the
machine.
The machine is placed straight in the correct horizontal
position.
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.
The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention
and that you use only the power cord that is
supplied with the machine.
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,

To connect the VM-1045 as illustrated in the example in Figure 3, do the
following
1
:
1. Connect a component video source (for example, an RGBS camera) to
the INPUT connectors.
2. Connect the LOOP BNC connectors (from channel A to channel D) to
the INPUT BNC connectors

to the acceptor (for
example, RGBS display 1).
4. Connect the OUT 5 connectors of each channel
3
to the acceptor (for
example, RGBS display 5).
5. Connect the power cord

1 Switch OFF the power on each device before connecting it to your VM-1045. After connecting your VM-1045, switch on
its power and then switch on the power on each device. Switching on the VM-1045, recalls the previous setup from the non-
volatile memory
