3.3 Your VS-66FW 6 Port FireWire Switcher
The Kramer VS-66FW is 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 isochronous
1
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-66FW via 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
3.3.1 Achieving 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-66FW away
from moisture, excessive sunlight and dust
3.3.2 Signal 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
