3 Overview
The Kramer TOOLS VS-30FW FireWire 800/1394b Repeater / HUB:
Is a 3 Port IEEE 1394b 800Mbps (S800) Hub that also supports legacy
FireWire speeds of 400Mbps, 200Mbps, and 100Mbps (S400, S200, S100). In
fact, you can connect several devices with different speeds, and the VS-30FW
will bridge the gaps!
Does not require any setup, and also supports hot swapping
Has 3 Bilingual IEEE 1394b connectors
1
Is powered by an external 12VDC power supply, or via a FireWire
connection from a PC
The VS-30FW is based on FireWire which:
Is a serial bus standard
2
that enables quick universal interfacing between
video and computer hardware items
3
Is simple to use and operates independently of the host system, letting
you connect more items than you otherwise could (as a computer only has
limited ports available), and for extended distances. Several can be cascaded
to create up to a 63 port FireWire Repeater / HUB
Supports Plug and Play

, and isochronous
5
and asynchronous applications
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 VS-30FW away from moisture, excessive sunlight and dust
3.1 About the VS-30FW FireWire 800/1394b Repeater / HUB
Many computers today come with one or more FireWire ports on the rear
panel. These ports let you attach many devices to your computer quickly and
easily. The operating system also supports FireWire, so the installation of the
device drivers is also quick and easy. Compared to other ways of connecting
devices to your computer (including parallel ports, serial ports and special
1 Adapting cables are available
2 Originally developed by Apple™ and published as IEEE 1394 by the Institute of Electrical and Electronics Engineers
3 Hardware items include digital cameras, computers, printers, VCRs, CD-ROMs, hard disks, scanners and graphic cards
4 Configures automatically. Whenever a device is added or removed the 1394 bus re-enumerates
5 Video / audio applications require constant transfer rates, which the serial bus provides by supporting isochronous transfers
