So is there a Thunderbolt out on the Cinema Displays?? I am VERY confused about this.
Thunderbolt and mini-display use the same port.
backward compatible? so my 27" cinema display was built with thunderbolt?
What they mean is that you can put the display on the end of a chain. So you could have five external HDs (once they've launched, with a pair of TB ports on each) and then the display sits on the end, terminating the chain.
EDIT: And because TB is compatible with MDP, the 27/24" ACDs will work, or other displays via the MDP adapters.
I understand this... But you can't daisy-chain a display unless it has an output port to daisy-chain to the next device.
Firewire peripherals that are designed with daisy chaining in mind have 2 firewire ports.
im assuming it will be the same for Thunderbolt peripherals. but the MacBook Pro only has 1x TB in and the cinema display TB out.
There we go! Gotcha! Also, can you access the USB ports on the back of the display if you use the Thunderbolt? Meaning, if you have 1 wire (thunderbolt) plugged into the back of the display and you also have an external drive plugged into the USB port on the back of the display, can you now access the external drive?
The 27" uses a USB breakout for the hub. So to use the USB hub in the ACD, you need to plug the breakout in to a USB port on the machine. Not ideal unfortunately, as I can envisage cables not reaching (the USB breakout is very short, and if your TB chain is long and is essentially acting as an extension cable for the display, USB won't reach)
Okay, see my terrible diagram.
Mac on the right, 5 devices chained to the TB port, and the display on the left. The two cables coming out the display (MDP and USB) are the same length in real life - so the MDP will reach the externals, but the USB is too short to reach the USB port on the Mac. You'd lose the USB hub on the ACD at this point, unless you use a USB extension cable to make it reach.
But presumably when the displays are next refreshed, they'll change this so that everything goes through TB/MDP. No help to people that already own a display, obviously, but great for those buying a new MBP + display.
You've got to find six devices which use Thunderbolt first.
If you daisy chain devices and a display (with one displayport), just make the display the last item in the chain. Was that really difficult to figure out?
With Apple and Intel behind it, I'm sure the devices will be on the way soon. I'd love a Thunderbolt RAID5 enclosure from OWC. 8 bay, if you're listening OWC!
Hm, possibly, but that'll need to have all Macs refreshed to TB before they do it, otherwise there will be a bunch of grumpy users. Plus I don't know if TB can provide USB functionality or not!
I guess some kind of docking stations will show up once this new I/O is established. It is the perfect connection for a docking station because you can forward any protocol. Hope they aren't too expensive.
Dasiy Chaining for anything but mulitple Displays (which works with DisplayPort 1.2 too) is not going to be very usefull because there will be few external harddrives with input + output. A docking station or a docking hub is much better imo and more convenient.
Most FireWire externals had input/output ports for chaining, so it'll happen. USB has never supported it full stop.
Seriously? Your gonna be a smart ass because I wasn't sure about something that was released an hour ago? All I was basically asking was if the CD had a TB in port in the back of it because I currently don't own one but was thinking about getting it for my MBA and I was thinking about future use with it incase I get a MBP or a MP. I'm sorry not everyone is like you and never has to ask questions.
This is just like SCSI! You can Daisy-Chain! yay!
So I have a question that I'll ask here.
Someone said TB and mini-display use the same port. So I don't need a TB adapter to use an external monitor? I can just use a regular Mini Display adapter and it will plug right in?
Thunderbolt compatibility (backwards compatible)
According to Intel's website:
This high-speed data transfer technology features the following:
Dual-channel 10 Gbps per port
Dual-protocol (PCI Express* and DisplayPort*)
Compatible with existing DisplayPort devices
Electrical or optical cables
Low latency with highly accurate time synchronization
Uses native protocol software drivers
Power over cable for bus-powered devices
I think that means all devices that have Displayport are Thunderbolt ready??
Well that's convenient, at least.
Smart ass? You seemed to know what you were talking about when you posted "But you can't daisy-chain a display unless it has an output port to daisy-chain to the next device." Instead of asking a question like "how do I use a device with only one port", someone less informed than you might have taken your post as fact, scary as it sounds.
this sounds perfect for what i need. TB to an external HD, then out to an HDMI adapter for my TV!
