Overview
Each high quality FireWire Distributor/Hub—the VM-10FW, VM-15FW,
and VM-20FW—are based on the IEEE-1394 (FireWire) standard, and let
you distribute one of two selected inputs.
1 GROUP 1: Distribution Amplifiers; GROUP 2: Video and Audio Switchers, Matrix Switchers and Controllers; GROUP 3:
Video, Audio, VGA/XGA Processors; GROUP 4: Interfaces and Sync Processors; GROUP 5: Twisted Pair Interfaces;
GROUP 6: Accessories and Rack Adapters; GROUP 7: Scan Converters and Scalers; and GROUP 8: Cables and Connectors

Your FireWire Distributor/Hub
In particular, the VM-10FW, VM-15FW, and VM-20FW:
Can distribute 10, 15, or 20 outputs/ports
Can be cascaded to increase the number of outputs, and since the unit
reclocks the data, cascading several machines may be used to effectively
increase the operation range
Support “Plug and Play” and “hot-swapping”
Operate for data rates of 100/200/400Mbps
On each FireWire Distributor/Hub, the:
Selected input signal is equalized for cable losses, and the outputs are all
relocked
Input ports are all electronically protected
Front panel LEDs show the status of all the IEEE-1394 ports
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 Kramer VM-10FW, VM-15FW, or VM-20FW away from
moisture, excessive sunlight and dust

VM-20FW as four 1:4 Distributors, see sections 5.3 and 5.5
5.1 Understanding the FireWire Connection
When connecting the VM-20FW, be aware that:
Not all ports need to be connected2
Everything depends on your computer’s software, and the firmware of the
devices. Sometimes, it is possible that a computer can work with many
FireWire devices simultaneously (like a distribution amplifier), sometimes it
can work with many devices in time-sharing mode (like a switcher). But most
often it is possible to work one to one. In this case, you have to disconnect all
the devices that are unnecessary at this time and leave only two of them. Since
FireWire is a hot-plug standard, you can connect/disconnect devices at any time
1 Each device(s) can serve as a source or as an acceptor (as appropriate)
2 Any unused port should simply be left unconnected. Port A/B must be connected to device(s) that can manage or broadcast
over 20 ports

5.2 Connecting the VM-20FW 1:20 FireWire Distributor/Hub
To connect the VM-20FW 1:20 FireWire Distributor/Hub, as the example in
Figure 2 illustrates, do the following:
1. Connect a FireWire device using a 1394 cable to the IN/OUT 6 pin:
PORT A (for example, a Video Camcorder)
PORT B (for example, a Laptop)
2. Connect up to 20 FireWire devices1 using 1394 cables to the OUT/IN 6
pin ports, for example, a:
Computer to port 9 and port 12
Video Camcorder to port 1, port 7 and port 11
Hard Drive to port 20
3. Connect the power cord (not illustrated in Figure 2).

5.3 Connecting the VM-20FW as Four 1:4 Distributors
You can use your VM-20FW 1:20 FireWire Distributor/Hub, as four 1:4
Distributors, without reference to PORT A or PORT B.
To connect the VM-20FW as four 1:4 Distributors, as the example in Figure
3 illustrates, do the following1:
1. Connect a FireWire device (source 1) via a 1394 cable to the OUT/IN 6 pin
port 1, and then connect up to 4 FireWire devices using 1394 cables to the
OUT/IN 6 pin ports 2, 3, 4, and 5 (outputs (1)).
2. Connect a FireWire device (source 2) via a 1394 cable to the OUT/IN 6 pin
port 6, and then connect up to 4 FireWire devices using 1394 cables to the
OUT/IN 6 pin ports 7, 8, 9, and 10 (outputs (2)).
3. Connect a FireWire device (source 3) via a 1394 cable to the OUT/IN 6 pin
port 11, and then connect up to 4 FireWire devices using 1394 cables to the
OUT/IN 6 pin ports 12, 13, 14, and 15 (outputs (3)).
4. Connect a FireWire device (source 4) via a 1394 cable to the OUT/IN 6 pin
port 16, and then connect up to 4 FireWire devices using 1394 cables to the
OUT/IN 6 pin ports 17, 18, 19, and 20 (outputs (4)).
5. Connect the power cord.

5.4 Operating the VM-20FW FireWire Distributor/Hub
To distribute the signal from:
PORT A (that is, from the PC1), push in the PORT SELECT button
The signal from the PC transmits to all the FireWire devices which are
connected and powered on
PORT B (that is, from the Laptop1), release the PORT SELECT button
The signal from the Laptop transmits to all the FireWire devices which are
connected and powered on
5.5 Operating the VM-20FW as Four 1:4 Distributors
After powering on the VM-20FW, the signal from each Group automatically
distributes to the respective four acceptors, as follows:
Source A at port 1 distributes to acceptors A1, A2, A3, and A4 at ports 2,
3, 4, and 5
Source B at port 6 distributes to acceptors B1, B2, B3, and B4 at ports 7, 8,
9, and 10
Source C at port 11 distributes to acceptors C1, C2, C3, and C4 at ports 12,
13, 14, and 15
Source D at port 16 distributes to acceptors D1, D2, D3, and D4 at ports
17, 18, 19, and 20

5.6 Cascading VM-20FW FireWire Distributor/Hubs
You can cascade several VM-20FW machines to increase the number of
outputs, and to effectively increase the operation range1.
To cascade three VM-20FW machines to form an expanded 1:60 FireWire
Distributor/Hub, as the example in Figure 4 illustrates, do the following:
1. Connect a FireWire device via a 1394 cable to the IN/OUT 6 pin PORT A
on the first VM-20FW machine.
2. Connect FireWire devices via 1394 cables to the OUT/IN 6 pin ports, as
follows:
On the first VM-20FW machine, to acceptors 1 to 19
On the second VM-20FW machine, to acceptors 20 to 38
On the third VM-20FW machine, to acceptors 39 to 58
3. Connect the OUT/IN 6 pin port 20 on the first VM-20FW machine to the
IN/OUT 6 pin PORT A on the second VM-20FW machine, and connect the
OUT/IN 6 pin port 20 on the second VM-20FW machine to the IN/OUT 6 pin
PORT A on the third VM-20FW machine.
4. Connect the power cord on each VM-20FW machine.
Figure 4: Connecting an Expanded 1:60 FireWire Distributor/Hub
