Unibrain
introduces a new family of Long FireWire-800™ cables.
Extend your topology up to 40 meters (131 ft) via a single 75
Ohm coaxial type cable and no need for multiple repeaters or bus
extenders.
Power requirements for the IEEE 1394 bus |
The most
important factor considered on any Firewire topology is
that sufficient power is provided to the devices
guaranteeing stability on the bus.
In long distance solutions, there may be significant power
loss across the power as well as the data lines.
Thus it is strongly recommended that the firewire adapter
on the PC side is fed with additional power internally
through its power connector.
With the 20m (65 ft) version of the Long cable you will be
able to operate reliably up to 3 industrial cameras
simultaneously without any additional power (provided the
firewire adapter in the PC is powered internally though
its additional power input).
With the 40m (131 ft) version you will need to provide
additional power (12V) unless the device is self-powered
(e.g. it is an external firewire disk).
If the device does not have input for additional power,
you can use a FireRepeater at the end of the long cable
for providing additional power to the bus through the
repeater's power input jack.
