I will only have three key pads at first and plan to have 2nd 630 added in the future. So if we can back up the program onto a disk I guess adding additional key pad is not alot of work. Is it possable to just purchase the key pads and program them from the back up? Is so the $500.00 to $600.00 investment does not make sence.

It looks like I had better make some note on the functions I will need to control from the KP's.

Thanks.
Mike
