2. X, M, S & R series
Advantages of X Series over M Series Dedicated sample clocks for digital I/O tasks.
All tasks are retriggerable.  On M Series this is only true for counter tasks.
4 Counters with advanced features (refer to the Product Manuals: X Series User Manual for more information).
100 MHz timebase available for all tasks (M Series uses 80 MHz for counters and 20 MHz for analog tasks).
Simultaneous sampling available on some boards.
Higher throughput for streaming over PCIe and PXIe busses.
S Series Multifunction DAQ Devices
NI S Series DAQ devices offer simultaneously sampled analog inputs. All S Series devices are built on a multiple analog-to-digital converter (ADC) architecture, allowing superior aggregate throughput and a higher sampling rate per channel than multiplexed devices.
R Series Multifunction RIO Devices
NI R Series multifunction RIO devices are multifunction data acquisition devices that feature a field-programmable gate array (FPGA) chip for user-defined onboard processing, as well as complete flexibility of I/O timing and triggering.
Advantages of M Series over E Series
The analog input and output FIFO buffers are much larger for M Series than E Series
M Series devices have 4 or 6 DMA channel, which increase performance when performing multiple tasks.
M Series supports NI-TIO counter features, such as two-edge separation and quadrature encoding.
M Series has 16 PFI lines, whereas E Series has only 10.
On M Series devices, timing signals such as counter output, freqout, and sample clocks, can be exported to any PFI line. On an E Series device, these signals must be exported through their dedicated lines.
The PFI and RTSI lines on M Series devices have debouncing filters, while those lines on E Series devices do not.
The digital input and output and PFI lines on M Series devices have better protection than the lines on E Series devices.
The Accuracy M Series boards support AO offset, unlike E Series devices.
E Series devices only have an AO internal reference of 10 V. For M Series, the Value boards have a reference of 10 V, the Performance boards have references of 5 and 10 V, and the Accuracy boards have references of 1, 2, 5, and 10 V.
M Series PXI devices have the ability to phase lock to a common PXI backplane clock for easier and more accurate synchronization of measurements across multiple devices. E Series PXI devices do not have this functionality.

File I/O operations pass data to and from files. In LabVIEW, you can use File I/O functions to:
Open and close data files
Read data from and write data to files
Read from and writ to spreadsheet-formatted files
Move and rename files and directories
Change file characteristics
Create, modify, and read a configuration file
Write to or read from LabVIEW Measurements files.

The waveform chart is a special numeric indicator that displays one or more plots. The waveform chart is located on the Controls»Graph Indicators palette. Waveform charts can display single or multiple plots. The following front panel shows an example of a multi-plot waveform chart.
You can change the min and max values of either the x or y axis by double clicking on the value with the labeling tool and typing the new value. Similarly, you can change the label of the axis. You can also right click the plot legend and change the style, shape, and color of the trace that is displayed on the chart.

Estimate completion time: 20 minutes. The exercise is easy, but since it will be the first VI that we actually create, it is good to allow ample time to explore the LabVIEW environment.
Instructions: Build a VI that converts °C to °F. When run, the VI should take an input value (°C), multiply it by 1.8, add 32, and display the result (°F). The front panel should display both the input value and the result. Save the VI as Convert C to F.vi.

16. Loopback Test הסבר מפורט על חיבור הכבל הטורי ראה בקישור.
A loopback test allows you to send and receive data from the same serial port to verify that the port is operational. To perform this test, you need to temporarily connect the proper pins to allow signals to be sent and received on the same port.
To perform a loopback test with no hardware flow control, you will need to connect pins 2 and 3 for RS-232 and pins 4 to 8 and 5 to 9 for RS-422/485. These connections can be seen in red below (figure 2 for RS-232 and figure 3 for RS-422/485).
When using hardware flow control, you will need to connect pins 4 to 6 and 7 to 8 for RS Pins 7 and 8 are used for RTS/CTS hardware flow control where pins 4 and 6 are used for DTR/DSR hardware flow control. For RS-422/485, you will need to connect pins 2 to 3 and 6 to 7. Both of these connections are required for RTS/CTS hardware flow control since RS-422/485 have differential connections. These connections can be seen in blue below (figure 2 for RS-232 and figure 3 for RS-422/485).
