Optional AC Adapter

<< < (2/2)

Hi,

well we implemented it that way to draw the power from the USB port if possible but don't want to enforce it.

There is a drawback if you use a Y cable, the tuner will become warmer since the current is higher (it's usually no problem as long as you don't have passive LNB switches in between, and the worst thing that can happen is a thermal shutdown).
Also a Y cable is not USB 2.0 conform (yes practically it exists). The best solution would be to use USB 3.0 but Linux doesn't support USB 3.0 well enough with USB 2.0 devices.

That said you know the background, we just don't want to enforce the use without AC adapter - even if it is a good feature of our devices.
Maybe in a few years when USB 3.1 is common enough the AC adapter can be skipped.

Hi!
There is also drawback when using AC adapter that some weird users will also need master/slave power strip to turn it off when not used.

In same time they might already have quality ATX PSU with up to 7 years warranty. Tuner can be placed inside some 5.25" bay storage box and powered from standard 4 pin molex. There are even similar brackets for external devices.

Delock 61824 - eSATAp(USB + 12V)?

And finally this option would help Raspberry Pi users to reduce number of (unnecessary) power supplies:

* This 2A “laptop brick” supply outputs both 5V and 12VDC and is terminated with a 4-pin Molex connector.
