1. Introduction What is NuDAM ? NuDAM is a series of data acquisition modules. It provides a total solution of the data acquisition network and control system. You can remotely control up to 256 NuDAM modules on RS-485 netowrk. All you need is to use a host computer, like PC (Personal Computer), with one RS-232 serial port for controlling the whole system. - Page 6 • High transfer speed NuDAM modules provide up to 115.2K bps data / command transfer rate. It can promote system bandwidth. • Simple command / response protocol All communications are performed with printable ASCII characters. This allows the information to be processed with string functions common to the most high-level languages.
