Overview  
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  
ñ
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 connectors1  
Is powered by an external 12VDC power supply, or via a FireWire  
connection from a PC  
The VS-30FW is based on FireWire which:  
ñ
Is a serial bus standard2 that enables quick universal interfacing between  
video and computer hardware items3  
Is simple to use and operates independently of the host system, letting  
ñ
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  
ñ
Supports Plug and Play4, and isochronous5 and asynchronous applications  
Achieving the best performance means:  
Connecting only good quality connection cables, thus avoiding  
ñ
interference, deterioration in signal quality due to poor matching, and elevated  
noise levels (often associated with low quality cables)  
ñ
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

Overview  
cards that you install inside the computer's case), FireWire devices are  
simple. Many peripheral devices (including: DV Camcorders, Digital still  
cameras, Storage devices such as External Hard Drives and Disk Arrays,  
Network connections, and scanners and printers) now come in a FireWire  
version.  
Connecting a FireWire device to a computer is easy – you just plug it into the  
port. If it is an uninstalled FireWire device, the operating system auto-detects  
it and installs software support for it automatically. If the device has already  
been installed, the computer activates it and starts talking to it.  
With so many FireWire devices on the market today, you easily run out of  
ports very quickly. The simple solution to the problem is an inexpensive  
FireWire hub. The FireWire standard supports up to 63 devices, and FireWire  
hubs are a part of the standard. You plug the hub into your computer, and  
then plug your devices (or other hubs) into the hub. By chaining hubs  
together, you can build up dozens of available FireWire ports on a single  
computer.  
A FireWire hub is like a network, with bi-directional signals. The standard  
defines FireWire as Peer-to-Peer connection; that is why two devices, or a  
device and a computer can talk to each other.  
It is important to note that 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 distributor),  
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 the FireWire is hot-plug standard, you can  
connect/disconnect devices at any time.  
Hubs can be powered or unpowered. The FireWire standard lets devices draw  
their power from their FireWire connection. Obviously, a high-power device,  
like a professional DV camcorder, will have its own power supply, but  
low-power devices like a Webcam derive their power from the bus in order to  
simplify them. The power for this (up to 1 amp at 12 volts) comes from the  
computer.  
If you have several self-powered devices, then your hub does not need to be  
powered, as none of the devices connecting to the hub needs additional  
power, and the hub itself can derive power from the computer. If you have  
many unpowered devices, you probably need a powered hub. The hub has to  
be powered from an AC adapter, which supplies power to the bus. The  
VS-30FW can supply up to 2.1A to the bus (each port can provide up to 1A).

Using the VS-30FW FireWire 800/1394b Repeater / HUB  
5 Using the VS-30FW FireWire 800/1394b Repeater / HUB  
To use the VS-30FW FireWire 800/1394b Repeater / HUB, as the example in  
Figure 2 illustrates, do the following:  
1. Connect up to 3 FireWire devices to up to 3 ports1, for example: PORT 1  
to a video camcorder, PORT 2 to a hard drive, and PORT 3 to a computer.  
2. Connect the 12V DC power adapter (see section 5.1) to the power socket  
and connect the adapter to the mains electricity (not shown in Figure 2).  
The ON red LED lights.  
3. Be sure that the power on each device is turned ON (see section 5.1).  
The ACTIVE green LED lights indicating that there is data present on a port.  
5.1 Powering the FireWire Devices  
Each FireWire device can derive its power in one of 2 ways:  
ñ
Independently, by connecting each FireWire device to its own power  
supply, while the VS-30FW is connected to the external 12VDC (12V,  
500mA) power supply (supplied with the VS-30FW)  
ñ
Via the VS-30FW that is connected to an external powerful power  
supply: the 12VDC (12V, 2.1A) (optional with the VS-30FW). In this case,  
each of the (up to) 3 FireWire devices can derive its power (up to 1A per port)  
from the respective VS-30FW FireWire port
