Operation Manual
NPRT 2200
5.10. NPRT Menu Options
The NPRT sub-menu provides some additional functions:
Setup Com Port
To change the com port used
Connect
To test communication with the NPRT 2200
Run Sweep
To start a new graph (same as File New)
Setup Com Port
Pick the desired port from the pull down list or select “Auto”. Com1 thru Com20 are supported.
All standard Windows com ports should work including USB to serial converters.
The built in USB port will also register as a Com port but the port number will vary depending on
the other devices that have previously registered in windows. The Windows Device Manager
may be used to identify the port number, but it is easiest to just use the “Auto” selection. If the
USB port registers at a com port number above 20, it will be necessary to use the Device
Manager and change the port to a lower number.
Connect
The “connect” function is for testing the serial port connection to the NPRT 2200. It just tries to
read the serial number and version from the unit.
5.11. Batch Operation
For automated testing, the NprGraph program can be run from a Windows DOS Command
Prompt window. A DOS batch can be used to run several NPR tests in a row without human
interaction.
Example command:
start /wait nprgraph 1234567 setup 2 3 /p
1.
The “start /wait” command tells the command prompt processor to start a Windows
application and wait for it to close before proceeding to the next command. This is
needed when running the command from a batch file.
2.
The “nprgraph” is the name of the application to run.
3.
“1234567” is the serial number of the unit being tested and will be used to build a unique
file name for the output.
4.
“setup” is the name of the sweep setup file to be used.
5.
“2” indicates the second band is to be used.
6.
“3” indicates the third notch is to be used.
