# 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 network. 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.

# 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 highlevel languages.

# Industrial 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.

# Watch-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.

# High isolation voltage

NuDAM provides photo-isolators, which ensure high isolation voltage, between the data acquisition circuits and the communication port. The fatal electricshock won‘t go through and damage all the modules on the network.

# Noise 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.

# Harsh environmental protection

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.

# 1.3 NuDAM-6000 series products overview

The NuDAM-6000 series provides the complete sets of data acquisition modules, including the communication modules, the analog input modules, the analog output modules, and the digital I/O modules.

# 1.4 EIA RS-485 Standard

The EIA RS-485 interface is a communication standard developed for multidropped 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.

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

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 is used to build the USB signal into RS-485/RS-422/RS-232 signal.

The ND-6531 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.

# 1.9. 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. Backup your software diskette
3. Insert “NuDAM Administration” disc into CD-ROM:
4. Change drive to the path of CD-ROM. For example, your drive of CD-ROM is F:, then change the drive to F:
5. Find the setup of NuDAM Administration and run it.
6. Please follow the steps of setup program then you can successful to install the NuDAM Administration.

# Objective of Initializing a Brand-NewND-6531

All NuDAM modules. except ND-6520, ND-6510, and ND-6530, in a RS-485 network must have an unique address ID, however, every brand-new ND-6531 has a factory default setting as following:

♦ Address ID is 01.
♦ Baud rate is 9600 bps
♦ RS-485 Interface
♦ Host Watchdog timer is disable

Therefore, to configure the brand-new NuDAM before using is necessary, otherwise the address ID will conflict with other modules if the ID of new module is identical to any of the existing one. The baud rate may also be changed according to user‘s requirement.

# Default State

The NuDAM I/O modules must be set at Default State when you want to change the default settings, such as the ID address, baud rate, check-sum status etc. All NuDAM I/O modules have a special pin labeled as DEFAULT\*. The module will be in Default State if the DEFAULT\* pin is shorted to ground when power ON. Under this state, the default configuration is set as following:

♦ Address ID is 00.
♦ Baud rate is 9600 bps.
♦ RS-485 Interface
♦ 8 Data bits,1 Start bit,1 Stop bit and none parity check.

Therefore, the communication between the host and the module can be easily set up as the same configuration, the initialization of a module is possible no matter what configuration is set under operating state

# Initialization Equipment

♦ Host computer with a RS-232 port.
♦ An installed RS-485 module (ND-6520 or ND-6530) with 9600 baud rate.
♦ The brand-new ND-6531
♦ Power supply (+10 to +30 VDC) for NuDAM modules
♦ Administration utility software

# Analog Output Modules

# 4.1 Overview of ND-6021

ND-6021 is an analog signal output module. It receives the digital command from host computer through RS-485 network. The format of the digital value can be engineering units, hexdecimal format or percentage of full-scale range(FSR). A microprocessor is used to convert the digital command to digital value to send to DAC. The DAC converts the digital value into analog form. The analog output can be either voltage or current output.

The ND-6021 is designed for safety. It provides many safety functions such as isolation, watchdog, and power on safe value. The opto-isolators provide 5000Vrms isolation voltage to isolate the digital section and the remote controlled analog equipment. The damage of power surges is avoided.

Another safety function is the watchdog. Whenever the host is loss contact with the remoted NuDAM module, or the micro-processor is down, the module will reset itself and send the safety value to the analog output therefore the industry safety is guarantee. The safety value / power-up value can be set by configuration software.

The analog output can be readback through the module‘s ADC. which can monitor the ’real‘ output of the device. The host can check the digital command and the real output to avoid short circuits. The slew rate of the output signal is also controllable by software.

# 4.2 Overview of ND-6024

ND-6024 is a 4 channel bipolar analog signal output module. It receives the digital command from host computer through RS-485 network. A microprocessor is used to convert the digital command to digital value to send to DAC. The DAC converts the digital value into analog form.

The ND-6024 is designed for safety. It provides many safety functions such as isolation, watchdog, and power on safe value. The opto-isolators provide 5000Vrms isolation voltage to isolate the digital section and the remotecontrolled analog equipment. The damage of power surges is avoided.

Another safety function is the watchdog. Whenever the host is loss contact with the remoted NuDAM module, or the micro-processor is down, the module will reset itself and send the safety value to the analog output therefore the industry safety is guarantee. The safety value/power-up value can be set by configuration software.

# 5.10 Overview of NuDAM-6080

ND-6080 is a counter / frequency input module. It has two 32-bit counter input channels with built in programmable timer for frequency measurement and supports both photo isolated and non-isolated input mode. The maximum counting value is 4,294,967,295 for counter input channel and the frequencyinput range is from 1 Hz to 20 kHz. A programmable digital filter can be enabled for both high- and low-level minimum signal width to reduce noise spike. Besides, the programmable threshold for non-isolated input can further reject noise on the input signal level.

The module provides the counter comparator or the alarm function. The alarm limit of two counters can be set independently by programming. The alarm status can be sent to digital output channels if this function is ON. The supervisor of a factory can ‘see’ or ‘hear’ the alarm if the digital output channel controls a real alarm device. The two digital output channels can be set for general purpose used if the alarm is disable. For example, connecting relay devices to DO channels, the NuDAM-6080 can be used to control the high-power devices.

# Command Set

# 6.1 Command and Response

# 6.1.1 Introduction

The NuDAM command is composed by numbers of characteristics, including the leading code, address ID, the variables and a carriage return to indicate the end of a command. The host computer can only command only one NuDAM module. The slave device may or may not give response to the command.

# Document Conventions

The NuDAM command is composed by numbers of characteristics, including the leading code, address ID, the variables and a carriage return to indicate the end of a command. The host computer can only command only one NuDAM module. The slave device may or may not give response to the command.

<table><tr><td>(Leading Code)</td><td>Leading Code is the first characteristic of the NuDAM command. All NuDAM commands need a command leading code, such as %,$,#,@,...etc.1- character</td></tr><tr><td>(Addr)</td><td>Module&#x27;s address ID, the value is in the range of 00 - FF (Hexadecimal) if no specified in the following.2- character</td></tr><tr><td>(Command Variable)</td><td>Items indicate command codes or value of variables.Variable length</td></tr><tr><td>[Data]</td><td>Some output command need data.Variable length</td></tr><tr><td>[Checksum]</td><td>Checksum in brackets indicate optional parameter, only checksum is enable then this field is required.2- character</td></tr><tr><td>&lt; &gt;</td><td>Identifies a control code character, such asfor carriage return, its value is 0x0D.1- character</td></tr></table>

# 6.1.2 Format of NuDAM Commands

(Leading Code)(Addr)(Command)[Data][Checksum]&lt;CR&gt;

When checksum is enable then [Checksum] is needed, it is 2-character.

How to calculate checksum value ?

[Checksum] = ((LeadingCode)+(Addr)+(Command)+[Data]) MOD 0x100

Example 1: checksum is disable

User Command: \$012&lt;CR&gt; Response: !01400600&lt;CR&gt;

\$ : LeadingCode 01 : Address 2 : Command (Read Configuration) &lt;CR&gt; : Carriage return 0x0D

Example 2: checksum is enable

Note: 1.There is no spacing between characters.

2. At end of command need a &lt;CR&gt; carriage return 0x0D.

3. Checksum is optional parameter.

# 6.1.3 Response of NuDAM Commands

The response message depends on NuDAM command. The response is also composed with several characteristics, including leading code, variables, and carriage return for ending. There are two kinds of leading code for response message, ”!“ or ”>“ means valid command and ”?“ means invalid. By checking the response message, user can monitor the command is valid or invalid.

Note : Under the following conditions, there will have no response message.

1. The specified address ID is not exist.
2. Syntax error.
3. Communication error
4. Some special commands does not have response.

# 6.2 Summary of Command Set

There are three categories of NuDAM commands. One is the general commands, including set configuration command, read configuration, reset, read module‘s name or firmware version, etc. Every NuDAM can response to the general commands.

The second category is the functional commands, which depends on functions of each module, not every module can execute all functions.

The third category is the special commands, including functions about the programmable watchdog timer, safe values, and the programmable leading code.

# Initialization & Installation

# 7.1 Software Installation

1. If you have already installed “NuDAM Administration” then skip other steps.
2. Backup your software diskette.
3. Insert “NuDAM Administration” disc into CD-ROM:
4. Change drive to the path of CD-ROM. For example, your drive of CD-ROM is F:, then change the drive to F:
5. Find the setup of NuDAM Administration and run it.
6. Please follow the steps of setup program then you can successful to install the NuDAM Administration.

# 7.2 Initializing a Brand-New Module

# Objective of Initializing a Brand-New NuDAM

All NuDAM modules, except NuDAM-6520,NuDAM-6510 and NuDAM-6530, in a RS-485 network must have an unique address ID. Every brand-new NuDAM has a factory default setting as following:

Address ID is 01.
Baud rate is 9600 bps
. Check-sum disable
Host Watchdog timer is disable

Therefore, to configure the brand-new NuDAM before using is necessary to avoid conflicting address. The baud rate may also be changed according to user‘s requirements.

The initialization procedures of a brand-new NuDAM are shown in the following sections. The procedures are applicable for initializing NuDAM-6013, NuDAM-6017, NuDAM-6018 NuDAM-6021, NuDAM-6024, NuDAM-6050, NuDAM-6052 NuDAM-6053, NuDAM-6054, NuDAM-6056, NuDAM-6060 NuDAM-6063, NuDAM-6067, NuDAM-6080, and NuDAM-6531.

# Default State

The NuDAM modules must be set at Default State when you want to change the default settings, including the ID address, baud rate, check-sum status etc. All NuDAM modules have an special pin labeled as DEFAULT\*. The module will be in Default State if the Default\*1 pin is shorted to ground and then power on module again. Under Default state, the default configuration is set as following:

Address ID is 00.
Baud rate is 9600 bps.
Check-sum disable.
Watchdog timer is disable.

Therefore, the configuration of the host and the module can be easily set identically and initializing a module will be possible no matter what configuration is set under operating state.

# Initialization Equipment

Host computer with an RS-232 port.
An installed RS-485 module (NuDAM-6520) with 9600baud rate.
• The brand new NuDAM module
• Power supply (+10 VDC to +30 VDC) for NuDAM modules
Administration utility software

Note: Never Connect the DRFAULT\* pin to Vs or power source just left it open or wired to GND.

# Initialization Procedure

1. Power off the host computer and the installed NuDAM-6520. Be sure of the baud rate of the NuDAM-6520 is 9600 bps.
2. Connect a brand-new NuDAM module with the RS-485. Set the module in Default State by shorting the DEFAULT\* pin. Refer to Figure 7-1 for detailed wiring.
3. Power on the host computer.
4. Power on the power supply for NuDAM modules.
5. Use the NuDAM Administration utility to configure the address ID, Baud rate and check-sum status of the module.

# Analog modules Data Format

# Unit Conversion

The data value in the command of the analog module is corresponding to the amplitude of the physical analog signal. The user should understand the data format to represent a analog signal by an ASCII string. The physical meaning of a data depends on both the unit conversion and the value. The unit conversion of the digits value can be configured by the setting configuration command. Three types of unit conversion are used in analog modules.

1. Engineering units.
2. Percent of FSR (Full Scale Range).
3. Hexadecimal or Two’s Complement Hexadecimal.
4. Ohm(For ND-6013)

# 8.3 Hexadecimal or Two’s Complement Hexadecimal

# Hexdecimal Format

Hexdecimal Format is for ND-602x modules.The data is in hexdecimal format as the bit 1 and 0 are set as ‘10’. The data string length is 3 characters. It is equivilant to 12 binary bits. Because the output of ND-6021 is unipolar, the maximum value of the digits is FFF(H) and the minimum value of the digits is 000(H).

As the output range is set to 0\~20mA, the value ‘FFF(H)’ represents 20mA and ‘000(H)’ represents 0mA. Similarily, as the output range is set to 4\~20mA, the value ‘FFF(H)’ represents 20mA and ‘000(H)’ represents 4mA.

The different analog output ranges have different resolutions. Refer to Table 8-8 for details.

# Appendix

# Application Note

1. When setting the baud rate and checksum, please connect the external Default pin to the negative pin of the DC power supply (i.e. GND). Please refer to the circuit path connection in Figure A-1. After setting the device, turn off the power supply and remove the connection between Default and GND. It is now ready for use.
2. NEVER connect or disconnect the Default pin signal while the unit is powered .
3. While powered up, please be careful when adding or removing pin connectors.
4. Keep the module seated away from large power source, strong magnets, etc.
5. Use a stable DC source. Avoid using large power source with heavy loads (as motor). If using batteries, please check to ensure for sufficient capacity. Don’t mix VS+ and GND signals! Use a 10-30V DC source.
6. All NuDAM transmission lines must be shielded twisted pairs (W22-26).
7. To prevent signal reflection, add a 120 Ohm resister to the last module (see Figure A-2).
8. When using the ND-6531, by all means, must connect the module’s FGND to the chassis’ Shield GND.
9. If using the ND-6018 Temperature Measurement unit, please be sure not to place it in

environments where the temperature changes drastically. It can affect accuracy.
