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.

Introduction • 1

1.2 Outstanding Features of NuDAM

Industry standard networking

z

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

z

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.

High transfer speed

z

NuDAM modules provide up to 115.2K bps data / command transfer rate. It can
promote system bandwidth.

Simple command / response protocol

z

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.

Industrial design

z

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.

Watch-dog supervisory

z

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.

High isolation voltage

z

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.

Noise immunity

z

The NuDAM provide extra noise immunity capability. An electrode, which is
coated inside the ABS case, can reduce electro-magnetic interference (EMI)
and noise.

Harsh environmental protection

z

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.

1.4 EIA 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.

1.5 RS-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.

1.6 NuDAM RS-485 Network Configurations

T

r

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.

1.7 Constructing a NuDAM Network

Go through the following steps, the user can construct a NuDAM network easily.

1. Setup a ND-6520 or ND-6530.

2. Connect the host computer with the ND-6520 or ND-6530.

3. Setup one or more ND-6510 if necessary.

4. Connect the ND-6510 to extend to RS-485 bus if necessary.

5. Install the NuDAM utility software or ND-6530 driver from disk.

6. Initialize the brand-new NuDAM modules.

7. Add the new NuDAM modules into RS-485 network.

Refer to chapter 2 and chapter 4 for executing step 1 and 2. Refer to chapter 3
for executing step 3, 4 and for understanding the time to install ND-6510. The
knowledge about the software for operating the NuDAM is in chapter 6. For
executing the step 6 and step 7, please refer to the install procedures of each
module and chapter 6.

1.8 Termination Bus

In order to avoid signal reflections on the bus, each bus segment has to be
blanked off at its physical beginning and at its end with the characteristic
impedance. An termination resister ( Rt) is intalled for this purpose. The Rt value

- 120Ω ± 2% is recommended, and the detailed connection of Rt can be referred
from the “Terminator Connection” diagram below.

1.9. Shielding

In case of increased interference, a shielded bus cables is recommended to use
for wiring between module and modules. In addition, a shielding also should be
done for the cable of power supply and for the signal cables.

Some experiences and recommendations are concerning for shield connection.

1. The shield should be connected with protective earthing at each bus
connection.

2. The shield should be applied additionally several times along the course of the
cable.

3. The Computer should be applied the shield directly to the appliance or to
separate shield rails.

2.2 Setup

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

3.2. Setup

Objective of Setup

In normal condition, it only needs to setup the NuDAM-6510 when the NuDAM
bus with more than 128 modules or the distance exceeds 4000 feet long. 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 user’s 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-6510. The user can set the
speed and the data format of the RS-422/RS-485 interface. The speed and the
data format on the whole network must be identity otherwise the communication
may be not correct.

To setup the ND-6510, 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 serial data format : one start bit, eight data bits, one stop bit, no

parity check
