not already.. but I can probably help out.. if you have access to a NPN, a few signal diodes and a +5VDCO relay .. then it can
happen pretty easily..
because of the lightning strike could you make sure +5VDC comes from the appropriate pins on the white header on that
its all in the spec sheet on www.soekris.com
