IPAD with Udac - Page 3

post #31 of 43

it apparently doesnt work, someone in the ipad thread tried it, my answer was, 'of course it doesnt work', its not a software thing, its the chipset that is used in the ipad and iphone v4 combined with the new software that is enabling this functionality.

I would not be so radical. I would like first to see the inside of the camera kit to check if there is any ACP (authentication coprocessor) from Apple or anything else which would get the digital audio out from the iPad.

 

If there is, then yes, it's just a software problem and it means Apple didn't allow iPod/iPhone to output digital audio to the camera connector kit.

are you suggesting there is a remote possibility there isnt any authentication device in there? of course there is, how else would apple engineer such a thing? they have no need to do any workaround, they own the tech and I think it possible that there is actually a legal requirement for them to include it from the record companies. anyway I do have some on the way and I will be cracking them open, but for other reasons, as I need no convincing that it is simply a device that has been designated as ipad only. now of course perhaps when they jailbreak the iphone v4, its possible that this service could be hijacked. I was more surprised that the iphone v4 didnt work as it uses the same chipset, but the post i replied to was regarding trying it on a touch v3, totally different generation and doesnt have the same media processor/CPU

"We are planning on supporting 24bit in the future. Sample rate is an 
interesting issue.. up to 48kHz is already supported cleanly."

^^ excellent I missed that

The camera connection kit is considered to be a Class A USD audio device from what I have read.  I run it directly into my RWA Isabellina HPA and used it with many setups at CanJam.

> Whoops, I posted this in the wrong thread anyways, so I moved it.

all that cable is is a USB extender, and a very short one at that, one can already just plug the USB cable into any computer to charge an iPad/iPhone. though in the case of the iPad, it will typically only charge if the screen is off, because most computers cant supply enough juice to charge the iPad at the same time it is being used. the wall adaptor is usually required in this case.

No, it's not just an extender, it increases the power. It's been widely reported that the iPad will not charge from PCs, or older Macs, or from many USB hubs.

 

"BoxWave's iPad Charging Adapter is the only adapter available that allows charging through any USB port.  You no longer have to be held back by Apple's restriction of not being able to charge your iPad on a standard USB port"

by definition you cannot multiply power. the only thing stopping those computers from not charging the ipad is a lack of current available at the USB port, and in the cases ive seen, its only when the screen is on, if you turn off the screen and come back later, the percentage of charge on the iPad will have increased.

 

also, i would not blindly trust the manufacturers advertising lines...to be frank, it looks like its just a USB extender...unless they put some magic power multiplier in there on the female end

 

but i guess its your money

According to Apple:

 

"Some USB 2.0 ports and accessories do not provide enough power to charge iPad. When this occurs the message "Not Charging" appears in the status bar next to the battery icon."

 

I've also tried the iPad with certain iPod wall chargers and gotten that message. The issue is fully explained here, and there is a great discussion about it here.

im not denying the issue. but as bigshot stated in the other thread, it will charge when the screen is off, but you wont be able to know if its charging unless you leave it for a while and come back to it.

 

what im taking issue with is whether that USB extension cable will actually make a difference, by placing it between the 30pin to usb cable the ipad comes with...which i doubt.

 

going from

Computer -> USB female/30 pin dock connector -> iPad

to

computer -> magical USB extension cable -> USB female/30 pin dock connector -> iPad

 

is not going to make a difference...

If you bothered to read about anyone's actual experiences with this issue you would find out that it will only charge off of certain USB ports when the screen is off, not all PCs and hubs will work this way.

 

I am not sure why you felt the need to attack my post, which was just intended to share some news about a new, useful, and inexpensive product for the iPad. As you have never tried this device, you are just speculating against it, which is known as "trolling".

 

The only person that has used it and written about it, the reviewer on Amazon, testifies that this device works exactly as promised; that is known as "making a difference". If it's just an extension cable, then why make it so short, and advertise it as something else?

 

I know what Big Shot is talking about as I have experienced it myself, where the iPad won't charge until it goes to sleep. Like I said ^, it only works this way off of certain ports and hubs, and on some it will not charge at all, regardless if the screen is off or on or the iPad is asleep or awake.

 

"The problem, says Apple, is that some USB 2.0 ports and accessories don't provide enough juice for charge the iPad. And in some cases, the iPad will charge, but only when it's in turned off or in Sleep mode."

 

Additionally, the device is not "magical"; it is possible to regenerate USB power using small DC-DC converter chips, like the MAX8614, which is used to regenerate increased voltage from USB 5V, all the way up to 24V.

 

My apologies to all regarding how off-topic this exchange has become. This wasn't the right thread to post this device in the first place as it has nothing to do with the uDac.

 

I suggest you read the links I have supplied before commenting any further, and if you must please do so in bigshot's "other thread"; peace out
