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 site you put here)
Relay contacts available on screw terminals, a DB-9 connector, and an
internal header on the board.

Did you get the temperature option?
I note that they talk about the NMI option, which can be set to
provide an NMI about half-second before a reboot.
The problem with these things are that if you have some sort of error
condition, the system will keep resetting itself and slamming into
the error that caused the reset initially. Perhaps you can have an
application set up a nonvolatile status file somewhere (it would be
nice if the card furnished this) so that you could determine where in
the whole affair that the reset kicked in and perhaps take some
remedial action, such as discarding a troublesome input or
transaction.

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.

Look for "**RARE** DB-9 plug"?

Pull one more pin.
No DataTerminalReady? or no CarrierDetect? Or are the frame ground
and signal ground twisted together?

Did you miss the manual and software downloads on the web page?
It lists the pinout for the DB-9 and has lots of other details.

I was in sort of a hurry. I saw the driver image, but not the manual.
Although now it seems ovbious to me that they would have that.
Old-timer's disease I guess.
