Overview

3.3 Your VS-66FW 6 Port FireWire Switcher

The Kramer VS-66FWis a high quality 6-port matrix switcher for routing 1394/FireWire interface signals. In particular, the VS-66FW:

￿￿Offers simple-to-connect automatic branch/leaf configuration that operates bi-directionally

￿￿Can be operated with FireWire™/i.Link™ implementation of the IEEE

1394-1995 and the IEEE 1394A standards at data rates of up to 400Mbits/sec

￿￿Supports isochronous1 and asynchronous transfers, as well as all the features of the 1394/FireWire interface, including hot insertion and removal

￿￿Can source the power to all ports

￿￿Stores and retrieves 15 setups in the built-in non-volatile memory

￿￿Includes a large, bright LED display on the front panel that shows the current status of the matrix, as well as PORT STATUS LEDs that indicate the status of each port

￿￿Includes a “Take” button for precise switch control, and a “Lock” button to prevent tampering with the front panel

￿￿Is housed in a 19" 1U rack-mountable enclosure

You can control the VS-66FWvia the:

￿￿Front panel buttons

￿￿Infra-red remote control transmitter

￿￿Remote contact-closure switches

￿￿Remotely by RS-485 or RS-232 serial commands transmitted by a touch screen system, PC, or other serial controller

3.3.1Achieving the Best Performance

To achieve the best performance:

￿￿Connect 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)

￿￿Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your Kramer VS-66FWaway from moisture, excessive sunlight and dust

3.3.2Signal Terminology

With regard to the signal technology used in the VS-66FW, note that:

￿￿Connections are between Branch and Leaf FireWire devices, rather than the regular In and Out, or Source and Destination devices. The difference is

1 Video / audio applications require constant transfer rates, which the serial bus provides by supporting isochronous transfers
