The Digital Controller Assembly contains the Digital Electronic Board,
Mounting Assembly and optionally a VGA Display.
The Digital Controller board provides control parameters to the
Analytical Processor board, stores and processes the data sent from
the Analytical Processor board. The Digital Controller also processes
communication with other devices.
The NGC8200's digital controller assembly provides control parameters
to the analytical processor board, stores and processes the data sent
from the analytical processor board. The digital controller also
processes communication with other devices. This assembly may also
contain an optional VGA display.
Information transmitted in a coded form (from a computer), represented
by discrete signal elements.
A Microsoft data exchange format generally used to transfer data from
one program to another. It is a very simple format to use and Totalflow
customers often use TDS to acquire data from Totalflow devices and
then transfer the data to an Excel spreadsheet using DDE. The
Totalflow Driver, TDS32, supports DDE and its network version,
NetDDE.
The branch of electronics dealing with information in binary form.
Refers to the signal received in binary format.
Refers to the signal emitted in binary format. An output signal which
represents the size of an input in the form of a series of discrete
quantities.
The process of translating discrete data into a continuously varying
signal. Common uses are to present the output of a digital computer as
a graphic display or as a test stimulus.
An electronic device, often an integrated circuit, that converts a digital
number into a corresponding analog voltage or current.
Deutsches Institut für Normung. German Institute for Standardization
set of standards recognized throughout the world.
Rail on which modules are mounted. Allows modules to snap on and
slide right and left.
A semiconductor that allows current to flow in one direction only.
A bank of switches typically used in setting the hardware configuration
and base address of an option card.
A current that does not change in direction and is substantially constant
in value.
A method by which information can be transferred from the computer
memory to a device on the bus without using the processor.
The conversion of chemical energy of a cell/battery into electrical
energy and withdrawal of the electrical energy into a load.
