Getting Started  
We recommend that you:  
Unpack the equipment carefully and save the original box and packaging  
materials for possible future shipment  
Review the contents of this user manual  
Overview  
FireWire is a serial bus standard1 that enables quick universal interfacing  
between video and computer hardware items2. FireWire hubs let you:  
Connect more items than you otherwise could3  
Extend the distances  
FireWire is simple to use and operates independently of the host system. In  
addition, FireWire supports:  
Plug and Play4  
Hot swapping5  
Isochronous6 as well as asynchronous applications  
Achieving the best performance means:  
Positioning your CVG-FW4x4 in a location free from moisture and away  
from excessive sunlight and dust  
1 Originally developed by AppleTM and published as IEEE 1394 by the Institute of Electrical and Electronics Engineers  
2 Hardware items include digital cameras, computers, printers, VCRs, CD-ROMs, hard disks, scanners and graphic cards  
3 A computer only has limited ports available  
4 Configures automatically without any driver. Whenever a device is added or removed the 1394 bus re-enumerates.  
5 You can connect and disconnect inputs and outputs dynamically, without having to restart the PC or cycle power  
6 Video / audio applications require constant transfer rates, which the serial bus provides by supporting isochronous transfers

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 that may  
adversely influence signal quality

Your FireWire Switcher  
The high quality CVG-FW4x4 4x4 FireWire Switcher is a mechanical 4x4  
switcher for FireWire signals, using 6-pin FireWire connectors. In particular,  
the CVG-FW4x4:  
Is designed for applications requiring a compact desktop unit for routing  
FIRE WIRE signals1 between any one of 4 sources to any one of 4 acceptors2  
Is ideal for high speed data signals up to 400 MB/s  
With its high quality switching components and carefully designed  
circuits, provides excellent isolation between inputs  
With its unpowered design is advantageous for applications in which  
various regulatory compliances would otherwise be required

Using the FireWire Switcher  
Sections 5.1 and 5.2 describe how to connect and how to operate your  
CVG-FW4x4 4x4 FireWire Switcher, respectively.  
5.1 Connecting the FireWire Switcher  
You can connect the CVG-FW4x4 4x4 FireWire Switcher to up to 4 sources  
and to up to 4 acceptors, using 1394 cables with 6 pin connectors.  
For example, to connect the CVG-FW4x4 4x4 FireWire Switcher to 2  
sources (a PC and a laptop) and to one acceptor (a digital video camera), as  
Figure 2 illustrates, do the following:  
1. Connect a PC to the IN 1 port and connect a laptop to the IN 3 port.  
2. Connect the OUT 4 port to the digital video camera.
