Difference between Firewire Cable IEEE 1394-Firewire IEEE 1394a-IEEE 1394b

I want to buy a 6 ft firewire cable 800 9-pin/9-pin to connect my Macbook Pro to an extrernal HD (G-Technology mini 500 GB)
I'm not sure what all the different IEEE #'s mean- IEEE 1394, IEEE 1394a, IEEE 1394b
Various reviews state not to buy cable that is all plastic at end since it breaks off. Some cables do not make good connection and fall out while others malfunction quickly.
I have MacBook Pro(13 inch), Snow Leopard installed, OS X 10.6.2, 2.53. GHz Intel Core 2 Duo, 4GB 1067 MHz DDR3
Any suggestions which brand firewire I should buy with which IEEE?
Thanks

On the back of your G-drive you're likely to see the label firewire 800, I believe that is what that drive uses. So does your MBP.
What you need is a firewire 1394b cable 9-pin to 9-pin, if you're worried about the brand you might try Cables-to-go, they sell good cable.
http://www.cablestogo.com/productlist.asp?catid=612
1394a is for the 400Mbps standard and the 1394b is for the 800Mbps standard.
The firewire that is on your MBP is 1394b and it's backward compatible to 1394a devices. If you ever need to connect a device that is for 1394a (400Mbps) then you'll need a cable that is 9-pin on one end and 6 or 4-pin on the other, which ever of the two the device uses.

Can I link my two laptops using IEEE 1394 (Firewire)?

Hi,
I have a X31 and a X60 laptop. Both are running on Windows XP Pro and both have IEEE 1394 (firewire) ports.
I seem to read it somewhere that I can do a network link between two laptops via the firewire ports.
However, it does not work for me after linking them with a firewire cable.
Am I missing something?

Am I missing something?
You have to configure the IPs on the both side as with any other network adapters.
Alternatively you can set the internet sharing to the fireware adaper, on one side only so the pc with internet shared will acts as DHCP server and the other will atutomagically configure itself with a correct IP.

My macbook's mini displayport is actually a IEEE-1394 Firewire port..

I jut got a mini displayport to DGA cable today and pluged in to my macbook but no signal to the external monitor.
I took a good look at the side of the macbook, and the mini displayport (supposed to be) has a mark of IEEE-1394 Firewire simble on top of the port.
left next to this port has a monitor simble but it is a different shape (got a longer tung).
Can any one tell me what is wrong?
By serching the web, they all say (and all look like) the one I pluged in is the mini displayport.
I'm panicking....

IEEE 1394/Firewire port not seeing DV

Hey All,
New to this forum, but looking for some help.
I have read just about EVERY previous topic regarding the 1394 issues and cannot find a solution to my problem.
I CAN see the 1394 setting in CMOS, and it is set to "AUTO". Also, in the Device Manager, I can see "IEEE 1394 Controller" with no IRQ conflicts. I have updated all of my MSI drivers as well as CMOS up to current. I have installed the DV drivers that came on my Camcorder's CD as well as programs that are designed to utilize the DV out on the camcorder. Also, I have reconnected my two 1394 ports on the motherboard in every configuration to check if it was a connection problem. Tomorrow, I'm gonna go get another cable, but doubt that's it; it's brand new.
I plug in my Digital Camcorder (Canon ZR85) and there is nothing. Windows makes no notice of it, and when I run the program designed to utilize it, it says that it is not connected. I have followed the owner's manual to a 'T' for setting it up.
Here's my info:
Athlon XP2400
512 MB RAM
120Gig drive (SATA)
Windows XP Pro (SP1a)
Canon ZR85 MiniDV
4 pin to 4 pin IEEE 1394 Firewire cable
(This MiniDV Camcorder will only connect DV via 1394, not USB 2.0)
Any help would be greatly appreciated!

So... seeing that no one responded to my initial request for information to solve this problem and I was not able to find any other helpful forums out there, I decided to do the prudent thing and buy a new motherboard/cpu, etc.
I bought what was supposed to be a top-line mboard, the K8N Neo Platinum with an AMD 3000+ chip, 512 PC3200 Crucial memory, 200 gig SATA HD, and 3dForce 6800. What I have come to figure out is that my brand new MSI mboard has the EXACT DAMN PROBLEM!!!!!!!!!!!!!!!!
I vowed years ago not to buy another MSI because of previous failures, but I was convinced that they were really producing quality boards now. Yet again, however, I guess I was fooled.
IF anyone has ANY help they could provide for this problem, I would be incredibly grateful. Otherwise, I'll have to take this mboard back, and I will NOT EVER buy another MSI product, and will be sure to tell everyone else the same thing.
Desperately,
Saint Raj

T61p - IEEE 1394 (Firewire) port does not show up in device manager in Windows 7 x64

I have a T61p. On the front, in the left corner, right next to the wireless on/off switch, is a IEEE 1394 (Firewire) port. However, if I plug anything into it, it's not recognized by Windows, and if I go into the device manager in Windows, there is no IEEE 1394 host manager or ports or anything listed there.
I have rebooted and gone into the BIOS, and I don't see anything in there about 1394 either. Is the port there, but the hardwire inside is missing? Do I need to enable it somehow?

Let me clarify that. I have something in the device manager called "SD Host Adapters", and under that "SDA Standard Compliant SD Host Controller". That thing has a Microsoft driver.
However, under "IDE ATA/ATAPI contollers", I do see "Ricoh Memory Stick Contoller", "Ricoh SD/MMC Host Contoller", and "Ricoh xD-Picture Card Contoller".
I also have "PCMCIA adapters" that has "Ricoh R/RL/5C476(II) or Compatible CardBus Contoller".
So, it would seem I have the right drivers for the card reader, I'm just missing anything for the IEEE 1394 contoller...

Resource Allocation for IEEE 1394 (Firewire) Cameras in Triggered Mode

In this article:
Resource Allocation for IEEE 1394 (Firewire) Cameras in Triggered Mode
http://digital.ni.com/public.nsf/allkb/ED092614FCCC900D86256D8D004A3B0C
it says "The Bytes Per Packet value represents the number of bytes that are transmitted at consistent 125us intervals on the FireWire bus during image acquisition" and the reciprocal of the 125us value would seem to be the source of a value of 8000 in a subsequent formula used to calculate the frames per second.
Is this 125us value independent from the firewire bus speed or a function of it?
If it is a function of bus speed, how does it vary with speed?
(Is the 125us value for 400Mbps and 250us for 200Mbps?)
Thanks!

Hello Warren
Thank you very much for getting in touch with us. Although the Firewire standard itself is not technically supported by National Instruments, I will do my best to assist you. I am currently referencing the IEEE 1394 documentation. From what I'm reading, I do not believe the 125 microsecond value changes. I have copied and pasted the paragraph of interest under Bus Arbitration from a document that I referenced:
The arbitration mechanism gets more complicated when isochronous devices are connected on the bus, because those devices have already been guaranteed bandwidth. Each arbitration round is approximately 125μs long, so bandwidth is allocated as a portion of the 125μs interval. The root node broadcasts (sends a message to node 63, the broadcast address) a cycle start packet, which begins the arbitration round. All interested nodes send an arbitration request as before, and the winning node is still the node closest to the root. After .04μs of bus idle time, the remaining nodes arbitrate for control of the bus. Once each isochronous node has completed its transaction the time remaining in the 125μs interval is used for asynchronous transactions. Up to 80% of the bus bandwidth may be allocated to isochronous transactions and the remaining 20% is left available for asynchronous transactions.
The original document can be found here:
The FireWire Serial Bus and its Implementation
I, unfortunately, cannot claim to be an expert on the IEEE 1394 standard but from what I've researched, the 125 microsecond time allocation is standard and bandwidth is then allocated accordingly. I may recommend consulting IEEE 1394 Trade Association (http://www.1394ta.org/about/Contact.html) for more in depth information. Please let me know if this is sufficient or if I can be of further assistance. I will do everything I can to ensure that your issues is resolved.
Have a great day!
Sincerely,

HP HDX X18T eSATA - IEEE 1394 Firewire SPECS

I'm having trouble finding the specs for the eSATA and the IEEE 1394 Firewire. I'm looking for an external hard drive that has one or both of these connections. Some have a selection of Firewire 400 or 800 and the specs list it as IEEE 1394 Firewire. Granted that my laptop is from 2009, but it is a workhorse.
I have several Iomega esata desktop drives, but I'm looking to a portable one.
Thanks for your help,

This question was solved.

It is definitely firewire 400 and the eSATA is going to be SATA I speed. What else did you need help with?

Firewire to Thunderbolt adaptor. 6-pin IEEE 1394 firewire for video transfer

Will the Apple Thunderbolt to firewire adaptor work with a IEEE 1394 6-pin firewire for video transfers?

You'll need a Firewire 800 (9-pin) to Firewire 400 (6-pin) adapter or cable, but yes, it should then work.

Difference between monitor cables

I am thinking about buying a Mac Mini and was wondering about what type cable I would need for my Dell monitor 2005FPW. What is the difference between the HDMI-to-DVI adapter that comes with the Mini and the Mini DisplayPort to DVI adapter?
I have never owned an Apple computer so I am clueless.

I think the difference is in the maximum screen resolution:
HDMI port 1920 x 1200
Mini Display port: 2560 x 1600

IEEE 1394 Firewire card

Hi I am new to this and would like to know if my laptop has a IEEE1394 card so I can transfer my pictures from my camcorder. If not is there a way to do this. I have a Presario CQ 70-116EM. Can I use a add on card?

Here are your official specs:
specs
No firewire. It is becoming rarer (less common) on laptops. If you had one it would look like this:
Some camcorders can use a memory card and many have a usb port for moving still images to a computer. The firewire is really only needed for capturing full-motion video for purposes of editing. If you must have a firewire port, there does not appear to be a way to add it as I do not see that your computer has an expresscard slot. You do have a cardreader slot so if you can transfer what is on the camera to an SD card you can then move the card to the laptop and transfer files that way. Otherwise look into the possibility for a usb transfer.

Difference between NI-ImaqDX Vs 1394 Legacy

In the project that I'm making with RT for desktop and firewire cameras, I'm using NI-ImaqDX, shall I continue with this or shall I use the 1394 legacy?
What are the diference between them?
Thanks in advance
Paulo Carmo

Hello,
You've better use the NI-IMAQdx functions, whitch are the most recent ones, IMAQ 1394 is now considered as a legacy, still here for those who developped there entire application with these VIs.
But normaly you can use both of them with a preference for NI-IMAQdx.
Here is a link to a doc that explains (maybe in a better way) what i'm trying to say.
Hope this helped,
Regards

Firewire IEEE 1394: Capture Card vs. On-Board Motherboard

I should know the answer to my question, but I don't...really. To capture video in my current computer, I had to install a video capture card with an IEEE 1394 Port. It is my understanding that there are motherboards that have "on-board" IEEE 1394 Firewire. If I purchase such a motherboard, does that mean I will not need a video capture card? In the specs of motherboards they will give the number of available IEEE 1394 Rear Panel Ports. Do these ports connect to "on-board" firewire and can they be used to capture video? Please set me straight. Thanks.

I agree with Neale. One consideration is the number of controller chips you have on either the MoBo connections, or your card.
Why is that important? Especially with Capture from a camera, it is always best to ONLY have the camera hooked to a separate controller chip. Some MoBo's and cards, might have multiple connectors, but they may all feed through a single chip. That might well preclude having any other FW device hooked to any of the other connections. Sometimes, it's tough to tell the number of IEEE-1394 chips, unless one has a good schematic of the board/card and the various chips are shown.
If one uses other FW devices, then the chip count will likely matter. While I have 4 MoBo connectors w/ 2x chips, I also have a multi-chip 4x connector card, plus a multi-chip 6x FW-1394b (FW-800) card.
The two things that you wish to avoid is daisy-chaining ANY camera, and connecting a camera to any shared chip. If I had a card already, and did not need to include it with the old computer, and had a spare slot on the MoBo, I'd install it too, but then I usually have 4-6 FW-800 externals, plus maybe 4 FW-400 externals, and still have empty chips available for my camera.
Good luck,
Hunt

IEEE 1394

Hi There, I have just purchased a Macbook Pro (first time Mac user) and want to plug in my DV Camera using its IEEE 1394 Firewire port, which the guy in the shop assured me I could do. It doesn't seem to fit in the Firewire 400 or 800 port, so am I then correct in assuming that it will not connect at all or is there some type of converter?
Thanks,

You will need the correct adapter. Which adapter to use depends on what kind of cable you have. I'm pretty sure your camera has a (mini) 4-pin firewire jack. If you're using a regular fw cable then you will need just one adapter.

Must use IEEE 1394?

I'm looking at purchasing a Panasonic HDC-SD90K hi def camcorder. It does not have an IEEE 1394 connector; it has a USB 2 connector. In reading the online material for Premiere Elements 10, I came across the following:
"HDV camcorder: Connect your HDV camcorder to your computer’s IEEE 1394 port using an IEEE 1394 cable. You cannot capture HDV using USB ports."
Does this mean I cannot buy this camcorder, or I cannot use Premier Elements 10?
(My iMac has IEEE1394 "Firewire" ports and USB 2 ports.)

By the way, this camcorder shoots in 1920x1080 at 60p by default -- which is not supported by this program and, if you try to edit it in this program, you'll likely have lots of issues.
If you plan to edit your video in Premiere Elements, but sure to shoot in 1080 60i only.
And, when you start up your Premiere Elements project, be sure to select the settings for Full AVCHD 1920x1080 5.1 audio.
