Introduction

1 Introduction

Congratulations on purchasing your CVG-FW4x4 4x4 FireWire Switcher.

This product is ideal for:

• Small digital video editing systems

• Data switching systems

The package includes the following items:

• CVG-FW4x4 4x4 FireWire Switcher

• This user manual

2 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

3 Overview

FireWire is a serial bus standard1that 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

• Isochronous6as 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

4 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 signals1between 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

5 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.

5.2 Operating the FireWire Switcher

You can route any one of 4 sources to any one of 4 acceptors when operating

your CVG-FW4x4 4x4 FireWire Switcher.

For example, to route the signal from the PC to the digital video camera, as

Figure 2 illustrates, do the following:

• Press the INPUT SELECTOR IN 1 button

• Press the OUTPUT SELECTOR OUT 4 button

The signal from the PC routes to the digital video camera

For example, to route the signal from the laptop to the digital video camera,

as Figure 2 illustrates, do the following:

• Press the INPUT SELECTOR IN 3 button

• Press the OUTPUT SELECTOR OUT 4 button

The signal from the laptop routes to the digital video camera
