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
