The high quality
Kramer TOOLS
™
TP-330FW
FireWire Range Extender/HUB
is a truly unique product that lets you extend the standard 4.5m (13.5ft) FireWire
range to 80m (262ft) with speeds of up to 400Mbps (see
Figure 2
) using common,
inexpensive TP cable.
The
TP-330FW
FireWire Range Extender/HUB
is based on FireWire which:
•
Is a serial bus standard
1
that enables quick, universal interfacing between
digital video, audio and data, and computer hardware items
2
•
Is simple to use and operates independently of the host system
•
Supports Plug and Play
3
, hot swapping
4
and isochronous
5
In particular, the
TP-330FW
:
and asynchronous
applications
•
Supports the provisions of the IEEE 1394a-2000 and 1394-1995 Standard for
High Performance 1394 Serial Bus up to 400Mbps
•
Enables 1394 400Mbps signals to be transmitted and received over extended
distances on twisted pair cable
•
Includes built-in protection from electrostatic discharge (ESD)
6
To achieve the best performance:
, by
suppressing all transient high voltages to allowed levels
•
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•
Position your
TP-330FW
away from moisture, excessive sunlight, and dust

Shielded Twisted Pair and Unshielded Twisted Pair
Standard STP or UTP cable should be used. Do not use skew-free cable.
Although Unshielded Twisted Pair (UTP) cable might be preferred for long range
applications, UTP cable should be installed as far as possible from electric cables,
motors, and so on, as these devices tend to create electromagnetic interference.
However, since the use of UTP cable might not conform to electromagnetic
standards, Kramer does not commit to meeting the standard with UTP cable.

2 Hardware items include digital cameras, computers, printers, VCRs, CD-ROMs, hard disks, scanners, and graphic cards
3 When a device is added or removed, the 1394 bus re-enumerates and configures automatically
4 You can connect and disconnect inputs and outputs dynamically, without having to restart the PC or cycle power
5 Video/audio applications require constant transfer rates, which the serial bus provides by supporting isochronous transfers
6 Often when connecting a "live" DV source to a receptor, an electrical potential difference or any other element creating a high voltage
(such as ESD or a live chassis) may permanently damage one or both of the connected devices. This high voltage may be seen as a spark
occurring at the instant of connection, or may not be seen at all, but nevertheless can result in costly damage
