1. Introduction
1.1 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. The maximum communication distance is 4000 feet from
the host computer.
NuDAM is based on the RS-485 multi-drop network system, each
module has an unique address ID. Using simple ASCII command
& response protocol through standard RS-485 interface can
control all the NuDAM modules in the RS-485 network.
The NuDAM modules provide direct linkage to a wide variety of
sensors and perform all signal conditioning, scaling, linearization
and conversion. The modules can be used to measure
temperature, pressure, flow, voltage, current and numerous types
of digital signals.
1.2 Outstanding Features of NuDAM
•
Industry standard networking
All NuDAM modules use the RS-485 communication
protocol for transmitting and receiving at high rates and over
long distance.
•
Two-wire and multi-drop communication
A single twisted pair of wires is used to transmit and receive
data between modules. Multi-drop capability makes system
configuration more flexible and easy set-up of a network.
