Introduction 1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 1,000-plus different models now appear in 11 groups 1 that are clearly defined by function.
Getting Started 2.1 Quick Start This quick start chart summarizes the basic setup and operation steps.
Overview 3 Overview This section summarizes: • The VS-40FW see (section 3.1) • FireWire® (see section 3.2), FireWire® 800 (see section 3.2.1) and FireWire® compliance (see section 3.2.2) • How to achieve the best performance (see section 3.3) 3.1 About the VS-40FW The VS-40FW is a high-performance bidirectional hub/repeater for 9-pin FireWire® 800 (IEEE 1394b) signals. It increases the number of ports available and/or extends the distance of FireWire® cable runs.
Overview 3.2 About FireWire® FireWire® is a serial bus standard 1 that enables quick universal interfacing between video and computer hardware items 2. It 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.
Overview 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.
Overview 3.3 Achieving the Best Performance To achieve the best performance: • Use only good quality connection cables to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables).

Connecting the VS-40FW Figure 2: Connecting the VS-40FW FireWire® 800/1394b Repeater / HUB 5.1 Powering the FireWire® Devices Each FireWire® device can derive its power in one of two ways: • Independently, by connecting each FireWire® device to its own power supply, while the VS-40FW is connected to the external 12V DC power supply (provided with the VS-40FW) • Via the VS-40FW that is connected to an external 12V DC power.
