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.
1.2 z 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. z 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. z High transfer speed NuDAM modules provide up to 115.2K bps data / command transfer rate.
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 NuDAM-6063 : 8-channel Relay Output Module NuDAM-6080 : Counter/Frequency Input Module 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.
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.

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.
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 host computer can only command only one NuDAM module.
(Leading Code) (Addr) (Command Variable) [Data] [Checksum] <> Leading Code is the first characteristic of the NuDAM command. All NuDAM commands need a command leading code, such as %,$,#,@,...etc. 1- character Module’s address ID, the value is in the range of 00 - FF (Hexadecimal) if no specified in the following. 2- character Items indicate command codes or value of variables. Variable length Some output command need data.
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.
