AD/DA Conversion and Data Acquisition made easy. 

Users : laboratories  & more.

Time & masterfilecontrolled    AD/DA conversion and Data Acquisition .

Easy analog control of anything that can be measured by a probe.

*************

*************

Made in two versions : 12/14bit  AD/DA ISA and 16bit  AD/DA PCI ( plug & Play ).  

A 16bit AD/DA USB version is to come , with even more control parameters available.

Free download  of an evaluation  version of the original 16 bit program with all program functions enabled , but this version has a couple of messages at program start !

Analog3.zip , best control, works with most Windows versions ( the ultimatezip file have dir info, extract to c:\ )

or a selfextracting arcive,  analog3.exe   ( made  and tested ok  in XP  Home Edition )

Find and download ultimatezip:     http://www.ultimatezip.com

Note!   This is an US version.   Before starting this program make sure Windows global setting is correct.

Global settings: Language / country = English(USA) , Timeformat : 24h without AM/PM  or 12h with AM/PM 

Start the program :  c:\analog1\analog03.exe .  

It's possible to start this program without any analog board installed .

-----------------

Notes about our 16 bit program version , hardware and 8Mz ISA bus :  

ISA Boards,  Analog / Digital I/O : Replace component   LS245 with HC245 .

Win OS , 16 bit or better : Win95 worked ok

*************

Our p&p system for advanced & laboratory use  :  32 bit program version ,  33Mz - 32 bit PCI bus , Plug & Play , Hardware: NuDAQ PCI-9118HR -16 bit ad / 12 bit da .

This modern 32 bit program version still have an user interface similar to the old 16 bit free ISA-version .

Win OS , 32bit or better: Win98 worked ok       PC program : 1200Euro

*************

Next version to come: USB , 16 bit AD/DA .

A short description of the program .

Analog(x) is a 16 channel AD_Logger & 1 indirectly controlled DA_Output .  

Function Basic.  The  PC-clock syncronized reference input unit value from the masterfile  &  the  measured input unit value  (  voltage input on the AD(0) is calculated to show the unitvalue ) , are indirectly controlling the output voltage DA(0) , ( As a termostate , flowcontrol or similar equipment )  .

More detailed :  Timers are set and controlled by the PC-Clock. ( Accuracy = 1 sec. )  .  The Masterfile is containing the reference_Unit values and is the main element in this controlsystem .  The Masterfile is composed by the program with little user effort . It writes directly to disc as a textfile  .  . The Masterfile gives dynamic output control of one DA_channel  . Output Voltage is determined by the DA_Output static settings, the input_unitvalue of AD_Channel 0 and the Masterfile_reading .

Logged input_value at AD_Input(0) ideally should give readings equal to Masterfile_reading, the program has different tools to make that possible .  

Dynamic DA_Output control : Sample Rate: ( Timercontrolled ) 11 sec or less.( Typical every second ) .  Read AD_Input (0) Unitvalue, converted from DC-value . Compare with Masterfile ( Unitvalue ) or Direct input by user  .  Read DA_Output settings . Calculate and set DA_Output voltage, this voltage is controlling the Output_Device. ( Triac/Thyristor with optoinsulated linear or PWM_input. ) .

Step_Time: ( System Clock controlled ) seconds to days . Read and hold next Masterfile reading  .  Log Time: ( System Clock controlled ) Step_Time * multiplicator  .  Logfile is written to disc as a textfile. " ADCX.LOG " , this file is easy to read in a spreadsheet  .  Date & Time, Masterfile reading and used AD_Input values are logged  .  Online help: Allways enabled. Easy and fast in use  .  Usergroups : Laboratories, Industry, etc  .  Unitconvert : 16 separate converters to make the system easy to use  .  All important readings on one screen .

Unitcontrol : In any form that can be measured by a probe. ( Pressure control, temperature control, flow control, flux control  & more. )

While running : You can increase the  masterfile and have a graphic update of the masterfile . Manually adjust the gain . Manually adjust the DA-offset . Use the dynamic viewer . You can copy the  "ADCX.LOG " logfile to another location on your harddisk , and run this copied file in a spreadsheet to make a presentation  , while the AD/DA conversion program is still running . OnScreen you can compare the last 1000 Masterfile values from the present reading  , with the  corresponding measured readings from the AD(0) channel , and vice versa .

Future :  The idea behind this well running 1-channel program will be the base of our future multichannel programversions .

About  hardware capacity :  Multi " Time & Masterfile Conversion " possibilities at the same time . The hardware  of todays "industrial AD/DA  PCI-cards  and USB  AD/DA adapters " have the functions needed , we "just" have to compose & write the software to make everything work , and most important , make it easy to handle . ( We have some ideas ) . 

The AD/DA Conversion / Data Acquisition controlpanel of 16 AD-input channels ,1 DA-output Channel , masterfile composer and more .

Magnified unitvalue & D/A Value reading . Aktivated by a mouseclick on the reading to be magnified . Deaktivate with a mouseclick on the magnifier .

Easy  "voltage to unitvalue " convert .

Unitvalue = (( Max input voltage - AD-offset )* Scale multiply ) + unit offset

In this view the  Unitvalue of AD ( 0 ) = (( 10 - 2 ) * 81.25 ) + 0
