3  Overview 
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 
) using common, 
inexpensive TP cable. 
The TP-330FW FireWire Range Extender/HUB is based on FireWire which: 
  Is a serial bus standard
 that enables quick, universal interfacing between 
digital video, audio and data, and computer hardware items
  Is simple to use and operates independently of the host system  
  Supports Plug and Play
, hot swapping
 and isochronous
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)
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 
3.1 
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. 
                                                        
1 Originally developed by Apple™ and published as IEEE 1394 by the Institute of Electrical and Electronics Engineers 
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
