This page contains pictures and graphs related to Data Acquisition Laboratory 1 (DAQ 1) of [[EGR 103]]. It has been updated for Spring, 2018.  This page underwent a major revision in Fall of 2017 based on the DAQmx drivers and MATLAB's elimination of legacy toolbox codes.

* Before running the program, the person at the DAQ machine will need to install the pydaqmx module:
 +
** Go to the Start button, find the Anaconda3 folder, and click the Anaconda prompt
 +
** In the Anaconda terminal that just opened, type
 +
pip install pydaqmx
 +
** One it is done installing (or confirms that it is installed), close the Anaconda terminal

B209 has machines with two different data acquisition cards.  Most of the machines have NI PCI 6014e cards, which will be what is discussed here.  The others have a newer NI PCI 6021 cards.

−
The NI PCI 6014e card can read up to 16 single-ended (8 differential) analog voltage measurements, has two analog outputs, and has 8 configurable digital input/output lines. The 6021 cards are more powerful but, generally in EGR 53, we will limit ourselves to the features available on the 6014e cards.

Be careful when making connections; improperly connecting wires can lead to catastrophic damage on the DAQ cards, as is shown on the second picture at right.

For the main part of the board, half-columns are connected together.  For example, rows (ABCDE) in column 3 are all connected.  Note, however, that ABCDE are not connected to FGHIJ.

Also, there are some helpful index numbers at the top and bottom to help determine which column you are in.  For rows X and Y, some indices do not exist.  For example, there are not Pins X6, X12, or X18, nor Y6, Y12, or Y18.

A diode is an electrical element that generally only allows current to flow in one direction - and only after there is a sufficient voltage difference across the appropriate terminals.

LEDs - Light Emitting Diodes - are a special form of diode that emit light when current flows through them.

'''''IMPORTANT NOTE''''' For the Fall 2010 semester for DAQ 1, the ''green'' wires in the pictures at right will '''not''' be used.

The pictures at right show both the breadboard and the CB-68LP once everything has been properly connected.  Note especially on the CB-68LP where the wires are - there will be no connections in the first two columns and there is only one connection - the black wire for digital ground - in the fifth column.
