Firewire Port and 12V

Good evening,
I have a Leaf digital back, that I need to plug in to a laptop, for professional reasons. It´s powered through a firewire cable by the firewire port. The firewire port needs to have 12V of power output, to make the digital back work. Does anyone know what macbook pro´s have a 12V capacity at the firewire port?
Regards,
Diogo

Here are the specifications. Apparently the battery alone will output the voltage range.

Why would the Firewire Port and/or External DVD-RW suddenly not work?

Hi, it's me again. I swear, I must be destined to just use Windows machines...
Anyways, I have a used/refurbished iBook G3 500MHz 320MB RAM Dual USB (1 Firewire)laptop running OS 10.2.8 that I bought a few months ago. I went and purchased an external Firewire/USB 2.0 DVD-RW drive as I only had a CD-ROM drive on my machine and I wanted the option to burn CD's or watch/read data from DVD's (I know that with my slow processor writing DVD's -other than data- would be a stretch and have other machines to do that with anyways so it wasn't a concern really). I received it and installed it, also installed the free version of Toast that came with it, and the drive worked fine. I have not needed to use the drive since then and have not used the laptop much at all since then really, but I do need to say that I did end up adding a new user account, though I can't remember if I changed the original Admin account and then still have the one I created myself when I first started the laptop after I bought it (had a fresh install of Jaguar on it, but I have no disk to re-install with if needed) or if I created a separate (new) account and ended up deleting the Original Admin accout (I know in Windows, you cannot delete the original Admin account but I do not know if that is the same for OSX or not). I did this as I wanted a master Admin account that I just wouldn't really use and then wanted the other as my main account (and use it to connect to my home windows network) and for some reason it would not let me put a check in the box to allow that account to do so (from either Apple or my user accounts) and so I know that my main user account now is set up to allow it (was it the old Apple user account or a new one, I can't remember- sorry).
Ok, so that is the back story to my problem, which happens to be this:
I just bought a new chip of RAM (512MB to make it a machine with 576MB RAM total) and as I had been looking at getting OSX Tiger (but didn't want to do it without the extra ram and had been considering Panther instead as well), I thought it was necessary if I wanted to not bog down my machine. I bought the Install Disks on DVD for Panther, as well as an upgrade disk (DVD again) for Tiger, therefore letting me use the External Firewire DVD-RW to install Panther, and if I liked I could go ahead and upgrade to Tiger (and if I didn't like it too much, or it slowed things down too much etc, then I could always go back to panther and have both available for future options). The extra RAM coming in handy here definitely.
So I was going to install the RAM today, and decided to go ahead and test out the External DVD to make sure it could boot from it (before making any changes to my system) and then go and install the RAM, and after that, install Panther to start... But I plugged all the cords and cables in, used my laptop with AC power even, and I could not get the External to show up at all... (kinda like the very current post right below mine but for the G4- it worked before, but now the firewire External just does not show up).
I only have USB 1.1 on this laptop obviously, and I don't even know if you could do a boot from an external with USB 2.0 if my laptop had it (the DVD player does). I was recommended to boot with an external firewire DVD or firewire to another machine with DVD capabilities to do the install. So my problem right now is getting slightly bigger, as of course, I can't seem to momentarily find the stuff that came with the External (spare USB cable to check and see if the laptop will recognize it at least with that and to show it is the firewire that is not working properly, or the disk that I used to install it -might have been only used to install Toast free version if it didn't need any drivers, but I don't know where that or the instructions for installation sheet currently is -- I am looking for it, but I have switched bedrooms just last week and I also seem to be missing a few other Windows laptop disks as well so there is a good chance that they are all together, I just need to figure out where, heh.)
I am waiting currently before installing the memory, though if I don't get the External working tonight, I may go ahead and do it first as at least I will have more memory on my laptop then, until I can get other stuff functioning and be able to do the Panther install.
But my main question is, is there something that would cause an installed external to suddenly not show up in OSX? Since I hadn't used it since that one day, and it was unplugged from the laptop itself, would that end up doing it, or more likely, the changing of the user accounts (though I have been trying to test it with different types of media and through both of my user account (which are both "admin" ones), though I do still have one of those being an account that was on there when the External DVD was first installed, so it really shouldn't have done this at all (one would think). So how big of a chance is it that the firewire has somehow gone dead and this is the main culprit to my wasting the past 4 hours on this???
I am currently scavenging around for an extra USB cable to try and test the External that way and will post the results when I can... I love the look and idea of macs, now I have a mac and want to upgrade it even, but why is it that whenever I attempt to use it after having not used it for a bit (and try to make the iBook feel better by using it more as I am sure it feels sad and alone sitting on the shelf while my Windows Laptop gets more attention), or try to fix it when it can be made better (and therefore used more often), the mac (all macs really), just seem to get all pissy and cause problems and make me spend hours upon hours trying to get things to work again??? You have to admit it, I am "mac cursed"... sigh I can program in 4 or 5 computer languages and am very advanced at many tech things (the ones I am not as good at I am still usually Average or Medium skilled) so it makes me wonder why I have so many tech problems with Macs when they are supposed to be the "easy" OS to use...

Actually, I think I have it all working now. After going back to the Plextor Website, I found out that the switch between the USB and 1394 ports only gets activated (switched over to the other) with you turn the device off first, move the switch and then turn it back on. I was sure that I had done this with the ibook, but maybe not as when I went back and did it with first the USB and then the Firewire cables, it did work. I definitely knew that I had not done this with the Windows laptop, the reason it would not have the USB work for me on it.
but back to the iBook, I was confused as it was only showing up as a DVD-ROM (which I guess is what they do until you actually open up the burning software to then be able to burn to it), and it also had the wrong Model #, which after more research, showed that it was the Internal DVD drive model version (PX-708A) compared to the actual model version (PX-708UF) which is the USB/Firewire (External) model. The firmware was really out of date as well (from June 2004 I think, v1.06) and they had v1.12 from Spet/Oct 2006 available so I went to get that (which was a hassle). They had nice easy Windows self extractor/installer packs, and then the BIN files for use for all systems (Sun OS/ Mac OSX/ Mac OS/ Linux etc as well as usable for Windows), and those needed a special Firmware Updater Application which was OS specific. Only I had the hardest time trying to get the OSX one as it would send me to a FTP site and not give me any clues as to which file(s) I needed to get and the Mac OS version was just for older 9.2 or below versions and didn't want to install under the OS Classic mode.
I ended up using my windows computer which made it easier to view with the FTP stuff as I have FireFTP in Firefox, and downloaded the files I thought I needed (to test out), and then realized my silliness, and just downloaded (as well) the Windows Auto Extractor/Installer as the Firmware is the same for all OS's, just the way to install/update it was different... So I hooked the DVD drive to my PC and updated the firmware, checked it out on here before moving it back to the ibook, where I checked that it still worked and had the new update version showing, which it did, and now I have my fully working and newly updated drive ready for the OSX installations... I had attempted to update my Jaguar system as well while online, but it had no new updates available (I guess those were all mostly Tiger updates that were just recently released).
I am now off to install my additional RAM, and after checking that it all shows up correctly, I will go ahead and do the Panther Install (and test it out and see if I like it or not).
For anyone that currently uses Panther on any mac, are there still any major problems I should know about before hand, or know about things that they have mostly fixed (like the issues with Firewire ports and External Drives that they had around the time Panther was first released for example)???
Thanks to all that helped... I now know to attempt an "eject" of any external HD (which I do have one that I will setup to use after I get Panther on the ibook) or CD/DVD drive instead of just unplugging the USB/Firewire cable.

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

IMac i7 Quad-Core firewire port and video camera

Has anybody tried to detect a video camera connected to the firewire 800 port?
I have already tried with two PRO tape-based DV video cameras: SONY PD170 and PANASONIC AG-HVX200E with no results. The same models do not have any problem with iMac 27" Core Duo 2.
Apple care protection plan has been useful only to know that if my iMac firewire port can handle an external Hard Disk, as it does, the compatibility with the camera is not a problem of Apple, but simply mine.
Any suggestion? Any help to find official pages by Apple with technical specification about firewire port and protocol of the new iMac 27" i7?
Thanks, Carlo

Today my Mac has finally been fixed. I had to send it to Milano, to SATA srl, where they have replaced the logic board. Now I can import video from my video camera using the FireWire port. Thank SATA!!!

I can't sync with FireWire port and I can't charge with USB port!!

Hi. I've a old model of iPod (M9244Y). After the last update, my iPod does sync with the FireWire port.
I tried with another PCs and Mac but it does work. Finaly I buyed an USB cable and this one syncs but not charge.
I've restored to early versions of iPod Updaters but it does not work again. Can I do somethig to fix it?
Why I can't sync with the FireWire port?
Please help me, I can't live without iPod, I can't live without music!!!

Do you have other Firewire devices? Do they work? Could be the FW ports are not working right.
First thing to do is reset the FW chip set on the mother board. Unfortunately, when you power down the computer there is always a bit of power still applied to the motherboard to keep things alive and this usually includes the ports to do stuff like detect when a device wants to wake up the computer. The downside of this is when a bus/port chipset goes into a weird state, power cycling the computer won't work.
So first thing to try is resetting the chipset and to do this you have to power down the computer and completely unplug the computer from the wall power (unplug the power cord to your Mac). Also unplug everything from the Mac's ports (USB, FW, Ethernet, etc.) to make sure no parasitic power is still there to keep the chip alive. Now let it sit for ten minutes (give those big power caps in there time to discharge). Now plug it back in, start up the Mac and see if your FW ports and the drive work any better.

Firewire as audio out - can i send my iTunes out through my firewire port and into a DAC?

I have a 5 year old (retired) MacBook with firewire 400 and 2 USB 2 ports. I want to use it as my music source for a fine stereo system. I want to know if I can use my firewire port to ship my digital music signal out to a DAC before sending it to my pre-amp in analogue format. OR, can I use the optical digital audio out in the heaphone jack to do it? What is the bandwidth of the optical out?

You do not need .Mac in order to send photos by e-mail. It sounds like you use ATT as you internet provider. Have you configured Apple Mail to be able to send e-mail yet? Can you send an e-mail text message OK?
If you haven't yet gotten Mail configured to work with your ATT account a quick call to ATT should give you all the information you need. Setting up Mail is easy.
Post back with further questions.

Older ACD USB/Firewire ports and a Thunderbolt MBA.

I have an older Apple Cinema Display (20) and a Thunderbolt MBA. Can I use the Firewire ports on the ACD if I use a Thunderbolt to DVI adapter?
Specifically, I have an older iSight external camera (Firewire based) that I would like to use with the ACD whilst the MBA is in clamshell mode. With the Firewire ports on the ACD, I'm intrigued by how I might access them with the MBA.
Is this possible?
TIA,

Same here. Since a few weeks, my MacPro ejects USB HDD's as soon as I write or read data on it.
(no I haven't installed something new at this time and all HUB's and HDD's have their own power supply, and yes they have been exchanged, so its not a broken cable or so !!!!!!!!)
After a reset of the NVRAM and PRAM its better for an hour or so, then starts to eject again. I've seen a lot of communities with exact the same question, but never a solution for it. There is also nothing in the support tab of apple.
Hope someone here can help me out or due to the fact that this is a AplleSupportCommunity, a Apple-Employee may starts to do his job and help this huge amount (I guess there are hundrets or tousand) of mac-user with exact the same problem....
btw: don't agree with MACATTACK2010 that this is a hardware problem, cause there are a lot of people in the
net that ask the same question with brandnew Hardware. I think it's an OS or an Update Bug, or may both.

Firewire ports and power draw while sleeping

After plugging in a power meter, I noticed my iMac was puling approximately 13W while sleeping. A bit of unplugging narrowed it down to the firewire ports. Each one was pulling about 6W, even while sleeping.
Will the firewire ports still draw power if the device is turned off? I'm specifically interested in an external drive that has a hard power-off feature (as opposed to simply sleeping). I'd like to keep it plugged in (I had been unplugging the cable except when needed).
I now I can check this myself, but I'm using the power meter for another project right now and don't want to unplug it and start over, but would like an answer "now."
Thanks in advance.

An open cable connected to any port draws no power. Think of it as kind of a cable to nowhere. Now...connect it to some external object such as a printer or external hard drive and the current draw of the device determines how much power is drawn. Most devices in standby draw about 5-15W depending on their complexity.

Firewire ports and power.

Are some Macs designed to allow some power to continuously flow through firewire ports even when the computer is shut down?
My iMac G5 (ppc) bought over a year ago will not allow my Lacie hard drive to shut down or power on automatically when my computer is shut down or turned on. The Lacie drive has an auto power switch feature that is supposed to do that. It functioned properly on my previous machine, an iMac G4.

Repeater function
Built-in repeater functionality allows FireWire data to pass between the computer and external devices even when the computer is turned off. Power from devices with power supplies runs to the repeater through the FireWire cable. The repeater does not work with devices that do not supply power.
Repeater functions between 8 V and 33 V and consumes approximately 1 W.
See your manual for your specific model.

Question about 6 Way Firewire Port and Ex. HD's

I recently bought the Belkin 6-Port Firewire adapter. Right now I have two external HD's ( 200 GB and 300 GB ),and my iSight connected. I was wondering if it was safe to have my two HD's always connected? I've been having issues with my screen turning dim and not coming back to normal until I restart. I reset the PRAM and still after using my iMac for awhile the screen turns dim, like as if were about to go to sleep, but when I try to brighten it, it stays the same brightness?

Assuming the harddrives have their own power supply the issue us unlikely to be related. Its unlikely to be related either way.
Are you sure you are not losing connection to the keyboard so when you try to brighten it takes a while for the keyboard to reactivate, plenty of people have had issues with the keyboard.
Also you can switch off the totally pointless slight dimming thing in the energy saver part of system prefs

My external hard drive and cd burner does not appear on the desktop of my mini. Using Firewire adapter from old to new firewire ports.

I have a new Mac Mini (2013) and older external hard drive (Lacie) and cd reader/burner (EzQuest). Both have the original Firewire ports and the Mini has the new kind. I bought a cable with both kinds of ends but I plug them in and they don't show on the desktop.

From what I've heard, sometimes certain devices will not have full functionality if they are FireWire 400 with an 800 adapter. Take Apple's original iSight external webcam. It had FireWire 400, and people report using a converter cable will give them video, but not audio.
When I first got my mini, my usb cd burner wasn't recognised by Finder or Disk Utility. After repairing disk permissions and a reboot, it worked fine.

Firewire port on Macpro won't work with my Sony DV Cam

I just got my Macpro and love it-but I do have a small problem that maybe somebody can help with.
I have a Sony PD100A. I was using this camera on my PC just up until last week and grabbing video via firewire into Premier. It all worked fine.
On my Mac, I plug into a firewire port, and neither iMovie or FCpro can capture from the camera. I seems to recognize the camera, but when you try to capure video, it just locks up.
I also have a firewire hard drive that I'm using to tranfer data from my PC to the Mac-it works just fine. Which leads me to believe somehow the camera isn't working with the Mac.
HOWEVER-I use a Digidesign Digi 002 rack attached to a firewire port on the back. The 002 has a passthrough firewire port on the back, so I hooked up the camera. Lo and behold, the Capture now works. But only by going through the 002.
I'd really like to be able to capture video by just plugging my camera inot the fron Firewire posts after I shoot some tape.
Does anybody have an idea why the front or rear firewire ports won't control or capture from my camera directly?
Thanks in advance for any help with this.

A couple of things to try…
1) Open a new user account and see if it works there
2) Reset PRAM and NVRAM…

3) Reset the System Management Controller…

4) Try your other Firewire ports
5) Boot off another drive and see if it's your software rather than possibly hardware

Capturing Video on New iMac with only 1 FireWire Port

Using one of the new Apple iMacs, what is the best way to capture digital video footage (Mini DV) into Final Cut using an external drive as your scratch disk? The iMac offers only one FireWire 800 port. Is it advisable to connect the camcorder to the FireWire port and use a USB 2.0 to connect the external drive? Or can you connect the drive via FireWire 800 and connect the output of the camcorder to one of the other Fireiwre ports on the drive? In this instance I am using a Lacie Rugged Hard Disk that has one FireWire 800, one FireWire 400, and one USB 2.0 port.

They often do not play well with other firewire devices on the same bus. And since all the firewire ports on a Mac are on the same bus, it can lead to incompatibilities during capture. On some computers they work fine, on others they collide.
Try it and see if it works for you. If it does, be happy. If it doesn't, you'll have to do the external drive/camera shuffle.
It goes like this:
• turn off the computer and all connected devices,
• disconnect the external drive
• connect the camera using a FW800 to FW400 cable
• turn on the camera
• turn on the computer
• launch FCP, set the capture scratch folder to the system drive then capture
• shut down the computer and the camera
• disconnect the camera and connect the external drive
• turn on the drive
• turn on the computer
• launch finder and move the captured files from the system drive to the external
• launch FCP and reset the capture scratch folder to the external drive
• open your project and reconnect the media.
Or, use a different (non-Canon) capture device.
Or, get a computer that has multiple internal drives or has expansion capabilites so you can add a firewire card to create a second independent firewire bus for the camera.
Good luck,

Connecting firewire port to USB

My computer does not have a firewire port. How can I connect my video camera which has firewire port to the computer which has USB port? I would like to edit my videos.

Has anyone tried this yet? What type of cable did you buy that worked? My Sony Handycam DV camera has a firewire output. My new Touchsmart 600-1100 (Windows 7 - 64-bit) does not have a firewire port, just USBs and S-Video. So I can't capture the video from the video camera to my desktop. My only workaround is to use my HP notebook (older model) that does have a firewire port and export the video from the camera to my external hard drive, then import it to my desktop (My DVD drive broke on my notebook or I wouldn't have a problem). Then I'll try to work with it with Windows Movie Maker or Adobe Premiere 7 to create the DVDs.
Now I ask myself: "Why did you buy a desktop without a firewire port???"

Firewire bus and ethernet not working

The computer has stopped recognizing anything plugged into the Firewire ports and also does not recognize the ethernet cable. I've restarted, unplugged everything, reinstalled the system, reinstalled some specific software I need, reset the PRAM and done the <command>-<option>-<o>-<f> commands:
reset-nvram
set-defaults
reset-all
Nothing has worked and if I plug the same components into another machine, everything works fine, so it must be with this specific computer (not cables, other hardware, etc.).
At this point, I'm thinking it's a logic board issue, but this machine just had a new one put in in May. So before I take it in again, does anyone have any other ideas? This machine is used in a laboratory to take images from a microscope, so a quick fix to this problem would be preferable to a repair, if possible.
Thanks.

Welcome to Discussions - it is probable the the replacement logic board has failed, the functions you mention are controlled by it, but try one of these solutions:
1. Downloading and installing the combo updater of the system software update they've just applied via "Software Update...".
2. Another trick is to restart each by zapping the parameter RAM:
Zapping the P-RAM:
After the startup tone, hold down <commandd><option><r> until 3 additional startup tones are heard, then release the 4 keys.
3. A 3rd tip would be to do Open Firmware resets on each:
After the startup tone, hold down <command><option><o><f> until the text screen is visible. When text can be entered, type the following commands, followed by the <return> key (there are no space characters in each command):
reset-nvram
set-defaults
reset-all (the Mac will boot up after this command is entered)
If none of them works, a trip to the repair shop would be indicated.
Please post back with results,
