ok
so I sent MOTU an email on monday late nite
its friday and they have not responded yet
.......Grrrrr
heres what it said:
hello
So I have my Ultralite
and its working very well
So far its great!
I would like to know more about field powering this unit ( where no AC power is available)
I have found the following on your site , However it looks like this response is more geared to the Traveller, but here's what you state:
As alternative to powering the Traveler via the FireWire bus or battery, or the UltraLite via the FireWire bus, you can use a DC adapter.
The Traveler or UltraLite needs a 12 watt DC power adapter. It can be of any polarity (tip positive or negative), and of any standard voltage from 10 to 24 volts. The easiest way to achieve 12 watts is to use a 12 volt, 1000 mA (1 A) power supply.
If you are using DC power with the Traveler make sure to turn the Traveler's "FireWire Bus Power Enable" switch to Off.
I am aware that EcoCharge makes a 12v SLA system for the Traveller
and the travelers back panel states a 12v supply
however, the Ultra lite is powered by 9v dc power supply either tip + or -
what I am wondering is that since it s wall wart is 9vdc is it possible to power the unit via a 9v battery?
I am looking into getting a 9v Lithium Ion battery (or 12v if needed)
currently I have a 12v Sealed Lead Acid that I used to power many different interfaces in the field
but its darn heavy
so I am looking to switch to a Li-Ion battery to save some weight
can the ultralite be powered from a 9v
or will that only be limiting the length of use?
all this to also help conserve my battery power in my iBook, of course
