Vista 128 with 3 alpha keypads

[jpalatine]

Hi, I need some help. I have installed the EVL4 and have everything working except my third keypad. I have the 1st keypad at address '00' the 2nd at address '01' the third at address '19' and the EVL4 at address '18'. The third keypad at address '19' is now non-functional. What are the proper addresses? I only use 1 partition. Thanks, Jim
