3 Overview
The high quality Kramer TOOLS TP-300FW FireWire Range Extender is a truly
unique product that lets you extend the standard 4.5m (13.5ft) FireWire range
considerably. For example, a pair of TP-300FW units (see
Figure 2 ) lets you
extend the FireWire range to up to 100m (300ft), and connecting three TP-300FW
units (see
Figure 3 ) lets you extend the FireWire range to up to 200m (600ft), using
common and inexpensive Shielded or Unshielded Twisted Pair cable.
The TP-300FW FireWire Range Extender 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 letting you
connect items for extended distances

Supports Plug and Play
3
, hot swapping
4
and isochronous
5
and asynchronous
applications
In particular, the TP-300FW:

Supports the provisions of the IEEE 1394a-2000 and 1394-1995 Standard for
High Performance 1394 Serial Bus

Supports the provisions of the IEEE 1394b-2002 Standard at S100 signaling
rates

Enables 1394 100Mbps signals to be transmitted and received across an
extended range on unshielded twisted pair cable

Includes built-in protection from electrostatic discharge (ESD)
6
, by
suppressing all transient high voltages down to the allowed level. In
particular, ESD protection for high-speed data lines to IEC 61000-4-2 (ESD)
15kV (air), 8kV (contact), IEC 61000-4-5 (Lightning) 12A (8/20us), and IEC
61000-4-4 (EFT) 40A (5/50ns)
To achieve the best performance:

Avoid interference from neighboring electrical appliances that may adversely
influence signal quality

Position your Kramer TP-300FW away from moisture, excessive sunlight
and dust

2 Hardware items include digital cameras, computers, printers, VCRs, CD-ROMs, hard disks, scanners and graphic cards
3 Configures automatically. Whenever a device is added or removed, the 1394 bus re-enumerates
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
