Introduction
1.1What 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.
Introduction • 1
1.2Outstanding Features of NuDAM
zIndustry standard networking
All NuDAM modules use the RS-485 communication protocol for transmitting and receiving at high rates and over long distance.
zTwo-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.
zHigh transfer speed
NuDAM modules provide up to 115.2K bps data / command transfer rate. It can promote system bandwidth.
zSimple 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.
zIndustrial design
The screw terminal plug connectors on every NuDAM module ensures simple installation and easy modification. The compact size allows the modules to be mounted on DIN rail, back-panel wall-mount, etc.
zWatch-dog supervisory
NuDAM contains a watch-dog supervisory circuitry that will automatically reset the module when the system fails. In addition, a user-programmable software timer provides a ‘safe’ output signal in the event of host computer failure.
zHigh isolation voltage
NuDAM provides photo-isolators, which ensure high isolation voltage, between the data acquisition circuits and the communication port. The fatal electric-shock won‘t go through and damage all the modules on the network.
zNoise immunity
The NuDAM provide extra noise immunity capability. An electrode, which is coated inside the ABS case, can reduce electro-magnetic interference (EMI) and noise.
zHarsh environmental protection
2 • Introduction
A surface coating covers on the PCB and electronic components of the NuDAM. It allows superior resistance to harsh environment such as humidity, salt spry and most harsh chemicals.

1.4EIA RS-485 Standard
The EIA RS-485 interface is a communication standard developed for multi-dropped systems that can communicate at high rate over long distance. The standard RS-485 can operate at speed up to 10 M bps over cable length up to 4000 feet.
The RS-485 interface can support up to 32 drivers / receivers on the same line. This allows actual networking applications on a parity line system (sometimes called multi-drop).
The RS-485 uses differential transmission on a balance line. Its easy wiring make it popular to use in industrial applications.
1.5RS-485 on NuDAM
The NuDAM improves the RS-485 capability for minimizing the user‘s cost. On each NuDAM module, a half-duplex RS-485 transceiver is used to communicate with other modules. A single twisted pair of wires, which provides standard differential transmission, is used to transmit and receive data between modules. The high input impedance of each NuDAM receiver allows up to 128 NuDAM modules on the same RS-485 bus without using a signal repeater.
The maximum transfer rate of NuDAM is 115.2Kbps which is lower than the maximum speed of the RS-485 standard. The slew-rate limiter on every RS-485 transceiver of NuDAM is very useful for transmitting error-free data, minimizing EMI, and reducing reflections caused by improperly terminated cables.
The NuDAM on a network may not use the same power supply. Therefore, the voltage difference between ground of the modules may exist.
Excessive output current and power dissipation caused by faults or by bus contention are prevented by the current limiter and the thermal shutdown circuitry inside the NuDAM.

1.6NuDAM RS-485 Network Configurations
NuDAM-6000 series is designed under RS-485 multi-drop network architecture. Up to 256 NuDAM modules can be controlled in a multi-drop network. The limit of 256 is due to command code. The network can be connected by simple topology (Figure 1-1) or branch topology (Figure 1-2) or free topology (Figure 1-3).
The ND-6520 and ND-6510 are the two basic communication modules to construct a RS-485 network. The ND-6520 is a RS-232 to RS-485/RS-422 converter. The ND-6520 is used to build a RS-485 port for the host computer by converting standard RS-232 signal into RS-485 signal.
The ND-6510 is the RS-485 signal repeater which is used to extend or to lengthen the network distance. A NuDAM bus can connect up to 256 modules, each segment is up to 128 modules. Whenever the numbers of the modules excess 128, the repeater should be used. In addition, the length of a standard RS-485 bus is up to 4000 feet, the repeater should be used whenever the length of a signal bus is more than 4000 feet.
The ND-6530 is the USB to RS-485/RS-422/RS-232 converter, and it used to build the USB signal into RS-485/RS-422/RS-232 signal.
The ND-6521 is an addressable RS-485/RS-422 to RS-232 converter, it allows the RS-232 devices easily link to Host by the RS-485/422 bus.

2.2Setup
Objective of Setup
In normal condition, it is not necessary to setup the NuDAM-6520. The default configuration of this communication module is 9600 bps and data format of 8 data bits with 1 start bit, 1 stop bit, and no parity check. Note that the data format is reserved to be compatible with other brand‘s communication port, it should not be modified if only NuDAM is used in a system. The baud rate can be configured according applications’ requirement.
Setup Equipments
Only screw driver is used to open the case. Software, power supply, and wiring are not necessary.
Setup Procedure
Only hardware switch setting can be setup in ND-6520. The user can set the speed of the serial interface ( RS-232 and RS-422/RS-485 ), and the serial data format. The speed and the data format on the whole RS-485 network must be identity otherwise the communication will be not correct.
To setup the ND-6520, use the screw driver to open the case, then change the switch setting. The new setting is available after power on. The case must be put back and locked carefully. Note that do not scratch the surface of the circuit while setting up, otherwise the surface coating or even the circuits will be damaged.
(Note: For Harware Rev.C1 or upper, there is switchless for Baudrate adjust. It is auto baudrate and parity, data bits adjust.)
Default Setting
♦9600 baud rate
♦10 bits series data format : one start bit, eight data bits, one stop bit, no parity check
