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
