Power Supply Information for Unibrain's FireRepeater Line of FireWire Repeater Hubs

12VDC 3A External Power Supplies/Adapters for Unibrain FireWire Devices)One of the more prevalent questions asked when purchasing FireWire repeater hubs is "do I need the optional power supply?" The answer to this question depends on what type of FireWire 800 or FireWire 400 devices are being used.

Quick Definitions: Self Powered vs. Bus Powered

A Self Powered FireWire device is one that plugs into the wall or utilizes internal batteries. One example is FireWire hard disk drives using 3.5in mechanism which come with their own power transformers and AC adapters. Another example are battery powered DV Camcorders. Most FireWire based audio equipment like those from Pro Tools is self powered as well

Bus Powered FireWire devices draw current from the FireWire bus itself. FireWire hard disk drives using 2.5in mechanisms are typically able to use bus power. Our CFFire800 Pro FireWire 800 UDMA CompactFlash reader requires bus power. Portable devices like the Apogee Duet require bus power as well.

If you are using self powered devices with a FireWire repeater hub, then there isn't a need to purchase an optional power supply. Conversely, if you are using bus powered FireWire products, you almost certainly need the optional power supply. [1]

Bus Power isn't always enough for multiple devices drawing current off multiple ports at the same time. If you daisy chain several devices, it also may draw more current than available. Further, the total amount of Amps a hub provides needs to divided by the number of ports to find per port current when each port is drawing current. In the case of Unibrain's FireRepeater 3A supply, this would work out approximately as follows:

Unibrain FireRepeater-800 Pro FireWire 800 IEEE 1394b Repeater Hub 5 Port
(3 amperes) / 5 = 0.6 amperes approximately per port (max)
Unibrain FireRepeater-800 Pro FireWire 800 IEEE 1394b Repeater Hub 4 Port
(3 amperes) / 4 = 0.75 amperes approximately per port (max)
Unibrain FireRepeater 800 FireWire 800 IEEE 1394b Repeater Hub 3 Port
(3 amperes) / 3 = 1 ampere approximately per port (max)
Unibrain FireRepeater 400 FireWire 400 IEEE 1394a Repeater Hub 3 Port
(3 amperes) / 3 = 1 ampere approximately per port (max)

Often computer companies will list ports by watts, instead of amps. When a company lists Watts for their FireWire ports, divide it by 12 (FireWire is typically 12 Volts) to find the Amperage.

The calculation above are the worst case scenario, typical application rarely see devices drawing current of each port.

Unibrain 3 port hub for 2 CFFire800 Pro FireWire 800 to UDMA CompactFlash Drives[1] A notible exception is the CFFire800 Pro FireWire 800 UDMA CompactFlash reader with Unibrain's 3 Port FireWire 800 Hub. We've tested this off a powered Mac port and were able to run two CFFire800 Pro's without the addtional power supply. Here is a quote from our test results.

While our CFFire800 Pro uses FireWire bus power, we knew it draws less than 500mA, while the MacBook Pro provides just under 1A of current while running on batteries. One product we offer, Unibrain's extremely portable FireRepeater 800, splits source current between two ports. With that in mind we set out to test two CFFire800 Pro readers with FireRepeater 800 to see if it provided enough power off a single FireWire 800 port to enable both CompactFlash readers; we found it worked flawlessly.

FireWire Cable Converter Adapter Plugs Illustrated

FireWire 800 (6 to 9 pin) (9 to 6 pin), and FireWire 400 (6 to 4 pin) Cable Converter and Adapter Plugs
How handy is this photo? It sure makes a lot of prose unnecessary. These adapters cover just about any FireWire 400 or FireWire 800 conversion scenario one could think of.

Converter plugs for FireWire cables allow changing the cable plug type at the very end to match that of the port it's being plugged into. For FireWire 400 (IEEE 1394a) ports, there are converter plugs allowing 9-pin cables to plug into 6-pin ports and converter plugs allowing 6-pin cables to plug into 4-pin ports. For FireWire 800 (IEEE 1394b) there is an adapter plug allowing 6-pin cables to plug into 9-pin ports.

Using Elan's U111-M SRAM and ATA Flash PCMCIA PC Card Drive with Unix-like Systems [first draft]

U111-M USB to PCMCIA PC Card ATA Flash and SRAM
EverythingHerePlus.com announces a first draft of a document which outlines the use of the BSD and Linux compatible USB reader for PCMCIA PC Card SRAM and ATA Flash memory devices. While the draft isn't complete, experienced users will have no problems using the command line instructions to complete tasks.

Elan's U111-M PCMCIA PC Card reader for SRAM and ATA Flash memory devices is unique in that the reader itself brokers all the interfacing with the PC Card and presents itself to the host computer as a USB mass storage device. In addition to working on The Windows platforms, the device works with various versions of BSDs and Linux. Because of this, the U111-M allows users of Unix-like platforms to perform actions on these cards using common command line tools that usually require specialized and expensive software for The Windows. EverythingHerePlus hopes the document will be helpful to those wanting to deploy the U111-M with Unix-like systems.
