Your VM-100CA
Has looping connectors that can be used to connect to a local monitor (or
some other component video acceptor), or to create larger systems1
Features trimmers located on the underside that can be used to adjust the
component video Level and EQ. settings
In addition, the VM-100CA:
Accepts a digital audio (S/PDIF) input, loops it and distributes it to 10
digital audio (S/PDIF) outputs using RCA connectors
Accepts an unbalanced stereo audio input, loops it and distributes it to 10
unbalanced stereo audio outputs using RCA connectors
Features audio level control for the unbalanced stereo audio output
Is housed in a 19" 2U rack mountable enclosure, and is fed from a
100-264 VAC, 50/60 Hz, 18 VA power supply
To achieve the best performance:
Connect 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)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VM-100CA away
from moisture, excessive sunlight and dust

Installing on a Rack
5 Installing on a Rack
This section describes what to do before installing on a rack and how to rack
mount.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5 to +45 Deg. Centigrade
Operating humidity range 5 to 65 % RHL, non-condensing
Storage temperature range -20 to +70 Deg. Centigrade
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 supply connections other than
direct connections to the branch circuit (for example, the
use of power strips), and that you use only the power cord
that is supplied with the machine.
How to Rack Mount
To rack-mount the 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

Connecting the VM-100CA
6 Connecting the VM-100CA
This section defines how to connect the VM-100CA. In particular, how to
connect:
A single unit (1:10 Video Component / Audio Distributor), see section 6.1
Several units, see section 6.2
6.1 Connecting a Single VM-100CA Unit
To connect a single VM-100CA unit (1:10 Video Component / Audio
Distributor) as the example in Figure 4 illustrates, do the following1:
1. Connect a component video source (for example, an HDTV satellite
receiver) to the COMPONENT VIDEO INPUT RCA connectors, and to
the S/PDIF INPUT RCA connector.
2. Connect2 the:
COMPONENT VIDEO OUT 1 RCA connectors to a plasma display, and
the S/PDIF OUT 1 RCA connector to an AV-Receiver
COMPONENT VIDEO OUT 10 RCA connectors, and the S/PDIF OUT
10 RCA connector to a home theater system
3. Leave the LOOP RCA connectors unconnected, and push in the Input
Term buttons to 75.
Note: if a loop connection is required, for example, to a local monitor,
plug it into the COMPONENT VIDEO LOOP RCA connectors and
release the Input Term button to Hi-Z.
4. Connect the power cord (not illustrated in Figure 4).
5. If required, adjust3 the Y, B-Y, and R-Y output signal level and/or the Y,
B-Y, and R-Y cable compensation equalization level.
1 Switch OFF the power on each device before connecting it to your VM-100CA After connecting your VM-100CA, switch
on its power and then switch on the power on each device
2 You can connect up to 10 component video output connectors to up to 10 component video acceptors. When less than 10
outputs are required, connect only those outputs of the VM-100CA that are required, and leave the other outputs unconnected
3 Insert a screwdriver into the small hole and carefully rotate it, trimming the OUTPUT level or EQ level

6.2 Connecting Several VM-100CA Units
You can connect several VM-100CA units to form an expanded video
component / audio distributor. For example, as Figure 5 illustrates1, connect
two VM-100CA units to form a 1:20 video component / audio distributor.
To connect several VM-100CA units, do the following2:
1. Connect a component video source to the COMPONENT VIDEO INPUT
RCA connectors on the first VM-100CA unit.
2. Connect the COMPONENT VIDEO LOOP RCA connectors on the first
VM-100CA unit to the COMPONENT VIDEO INPUT RCA connectors
on the second VM-100CA unit.
3. Release the Input Term button to Hi-Z on the first VM-100CA unit, and
push in the Input Term button to 75 on the second VM-100CA unit3.
4. Connect the COMPONENT VIDEO OUT connectors4, as follows:
On the first VM-100CA unit, to component video acceptors 1 to 10
On the second VM-100CA unit, to component video acceptors 11 to 20
5. Connect both power cords (not illustrated in Figure 5).
Figure 5: Connecting Several VM-100CA Units
1 Audio connections are not shown in this example
2 Switch OFF the power on each device before connecting i t to a VM-100CA unit. After c onnecting all VM-100CA units,
switch on their power and then switch on the power on each device
3 In general, when looping, the Input Term button should be set for Hi-Z for all units except for the last one in the chain
4 When less than the maximum outputs are required, connect only those outputs that are required, and leave the other outputs
unconnected
