recently took over managing a little motel in the back woods, i am not by any means an IT person but i need to somehow figure out how to make this system ring through to individual rooms when someone calls in and dials a room number i have tried to install the software off the disc that was duct taped to the machine ( Panasonic Product Documentation, Prompt Data & PC programming Software) but when i go to hook the usb cable to my laptop it tells me i do not have the drivers for it so i went on google and downloaded the drivers (which there were none for Win 7)
