Check the voltage output of the LM324 board. It looks like the JDIO should accept anything over 10vdc as a high. Chech the circuit because the LM324 can run upto 32 vdc in single supply. You may have to just tweek some values on that circuit.
If I remember correctly the device has to ask for the power.
It asks for it in units of 100ma in 2.0 and 150ma in 3.0(usb on the go)(Up to 5 units per device). I also think the max power can change depending on the communication speed.
I rember something like that when I used that DAC.
I think it had something to do with not toggling the CS signal between the two commands.
Also if the CS goes high before the 16th bit it aborts the command.If you switch which commands you send first does the other output work...
Don't forget the polarity of the transformer
-200 volts should be reflected back to the primary.
(Ignoring parasitics).
ie. 400 volts is across the primary during the on time and
-40v on the secondary (no conduction due to rectifiers
being reverse biased). During the off time the secondary...
Either one will work, the real problem is the large
amouts of data that needs to be transfered for any type
of quality graphics. I would look at the imx 27 or a
Davinci processor. Depends on the applications.

Lecroy offers an option for 32 digital inputs.

Agilent and Tektronics allow some of their scopes and logic analyzers to be connected together and function as one.
Google low voltage disconnect
They are basicly what MacGyver said.
Some have allot of features like high voltage trip and
ethernet warnings. Make shure its powered off the
charger/load side and not the batteries or it will
drain the batteries for you.
This is one of my favorites:

Alot depends on the LED's you have.
You need to check the led data sheets to find out
how much light and at what wavelength the led gives off
at a set current.
National semi, cypress and philips have alot
on leds and color mixing.

You AC bridge should stop it from going back to the
mains.
How do you plan to draw current when the ac is on the
lower part of the cycle? ie. 48 volts to 0 volts.
Is the full bridge going to buck and boost?
Like Scotty said a standard boost pfc can handle KWs.
