I just picked up one of these:

from ebay for $7. It looks like it watches the machine for locked up
software, then presses the reset button for you. What else can I do
with this? What's the db-9 port for?
From the page you linked to:
"Relay contacts available on screw terminals, a DB-9 connector, and an
internal header on the board."
I'm guessing it's so you can connect the on-board relay to something
external to the machine.
