Matrix Orbital Corp

Hi,
i've just bought a keypad interface from matrix orbital, i've connected it to my lk204-25-pc and.... nothing happened, i've tryed the matrix orbital demo software and the keypad and the gpo do not seems to work..
please help me, i've connected the keypad cable with the little dot on the first pin (is it right ?)

thanks,
francesco

middle of the keypad out.

problem solved.... in the reality it's working perfectly, the demo program do not show me nothing, but using lcdc and making some test i've found all the key mapping...
i've also putted the first pin of the connector with the second of the lcd and all it's working perfect right now !
thanks...
