Extend FireWire cables to media devices up to 70 feet away with the LTM-FDR Inline Bidirectional Firewire Repeater. Give yourself more working room, without sacrificing power or data. This item can self-power, off the FireWire cable itself, or you can use the included AC power supply to augment the power on the line. Additional 12V battery supplies are also available. The box itself is designed with slots in the support bracket to align and secure incoming cables to the box with the included zip ties once they are plugged in. A status indicator light lets you know the device is working.
