if you see an access granted on the the software this mean that the
programming is ok...

you must have connected the latch on the wrong connector/relay or didn't
supplied the 12 volt to the relay..the n750 doesn't provide the voltage from
the relay you need to run a wire from the 12 volt supply then pass it to the
relay (usually I use the Common connection to the relay fro the 12 volt)
then use one of the 2 remaining output from the relay (n.o should be the
one) to connect the current to the latch..the return wire from the latch
should be connected to the negative of the power supply output..
