through use of modems).



GENERAL DESCRIPTION

The DLC system couples the latest micro-computer technology and analog/digital electronics with customized software. This system provides a range of support for the most casual of users to the requirements of the most demanding. For most data collection operations, use of the menu driven operational control program is all that is needed to configure the system parameters and to collect data. Where data conversions or specific output control is required, equations or control programming may be added to the DLC operational control program in the form of simple BASIC language statements.


The DLC software platform is implemented as a BASIC language interpreter with numerous data acquisition and control extensions to the language. Performance critical functions are implemented in machine code for the best possible performance. A feature of the DLC system platform is that it allows you to either extend the DLC operational control program or create your own program(s) to tailor the menus, user interface, or operational characteristics uniquely to your needs, all in the BASIC language .. The DLC provides for 30K bytes of BASIC language programming space (much like running a BASIC program on a personal computer). Programs or data can be stored or loaded using optional solid-state credit card sized memory cards.

Example conversion equation and heater control:

REM Convert Linear Temperature Sensor
REM (Kelvin) Output to Fahrenheit
10101 X(2)=-463.4472+.1788618*X(2)
REM Heater Control (Digital Output 5)
10102 IF X(2)>73 THEN DIG W,5,0
10103 IF X(2)<69 THEN DIG W,5,1

If temperature (channel 2) goes below 69 (degrees F) then turn heater on. If temperature goes above 73 then turn heater off.
