Basic description

A2 Logger is specifically modeled portable PC with plug-in system for data acquisition, measurement and management. Because of its PC compatibility A2 Logger provides high comfort and convenience in application. Accompanying software provides easy customization to the new measuring system environment.

The logger has a built-in 15 inch TFT monitor which can also easily be separated from the platform and set up somewhere else. Keyboard and Mouse are wireless. There can be connected printer, local network, CD or external hard disk, floppy disk, a USB and RS-232/485 ports, and many other interfaces on the logger. CompactFlash provides the application in an environment with high levels of vibration or in an area where the hard drive may not work reliably. Logger is open for a possible upgrade with the spread-spectrum radio, GSM mobile telephone system or the satellite data and a GPS receiver for precise location and timing of applications if required.

A2 consists of three basic components: 

1. Aluminium box with passive backpanel with 8 ISA slots and power supply system. It is installed plug-in PC Module with Intel "Core Duo" processor 2GHz (or Atom 1.3 GHz) with 1 GB of memory, in the rightmost slot. Hard disk is a 2.5-inch, 120-GB (250 GB option) and is more resistant to vibration and shock than conventional 3.5 "drives. Logger operates using power supply of 220V (120 to 260V) but it can be supplied using 24V DC power supply (18 to 32V) if requested.
    

2. The second integral component is the A / D module. It can be installed one of the three types of A / D modules: A2-28-AD,  A2-28-IS or A2-28-MS in A2 logger. All three modules have the same platform but different "front end". The first model (AD) AD is a standard module, and the second model (-IS) has a built-in isolation amplifiers. The third type can be installed up to 12 isolated signal conditioners.                                                                                                Common to all three boards is that they are instrumentation plug-in modules with 16 or 12 analog input channels that have 12 or 16 bit analog / digital converter with a sampling rate of 250 KHz, DMA and 2K FIFO memory . In DMA mode, Logger can work with two AD modules and in this case it has 32 analog channels. The third and each subsequent A / D module in the system when used will not work in DMA, but in the "Polling" mode. It can be added   D / A, digital I / O or counter / timer modules if the application requires it. All I / O modules are downloaded from the PC controller A2. Their specifications and prices are on the section I/O modules for A2.
    

3. The last component for A2 logger configuration is 17" TFT monitor with 220V supply (optional24VDC). Also, it can be delivered with "Touch-Screen" monitor, 15" ili 17" TFT.

Software

Software package for A2 Logger executes data acquisition at 16 or 32 channels, continuous streaming to disk and the graphic display on the monitor. It prints selected signals and current events in a given window, if requested. Monitor can display one or more channels at the same time, with 32 channels maximum. Signal printing is horizontal, from left to right or from top to bottom (like paper printers). Time of full signal viewing is set by user and it depends of needs, and can be from one second to one year.  Any part of vaweforms can be zoomed in after-treatment to the last LSB, in time to the thousandth of a second.

Data from the events can be recorded every minute, hour or day. These data can be saved on a CD for archive. The recommended operating system is Windows 2000/XP.

Using the logger has been simplified so that users who are not computer specialists can easily use it. It only takes a short informative training. Unauthorized users can not enter the system setup, but this is only possible by authorized users with passwords.

If the user wants to write his own software for A2 Logger, the software drivers are available for use. Electronic Design has a library of software drivers and software support in the form of finished software packages for graphical programming. With the system, 32-bit software drivers for ED-Link for C (DOS), C + + and Visual Basic for Windows 2000 are delivered. Using these drivers, developer is relieved of the need for detailed knowledge of hardware systems. 

As an alternative to software drivers, there are menu-controlled software packages for graphic programming applications. User, depending on the purpose and cost, can choose a package that he wants to use. These are the LabVIEW (National Instruments) and LabWindows/CVI  (C for Virtual Instrumentation), used by many traditional users.

The mentioned software packages for graphic programming applications allow users to develop their own applications without writing conventional code, for a very short time. Applications are created by drawing a diagram of flows, with the help of ready-made functional blocks, combining a professional screen display with a variety of tools for data acquisition, measurement and process control.

Ordering A2 logger has three steps: the selection processor, the selection of A / D module and the range of options.
