[757labs] Honeywell / Northern Computers board

[Jody Franklin]

Per the docs the power down voltage is pretty high on the battery I  
don't think it would cycle up from an idle state as it's a pretty high  
draw. Besides the manual does refer to running the panel exclusively  
off DC but that it prevents you from using battery backup if you do.  
*shrug*

As for building the cable, sure. I like building stuff. :D
