2 LDPS_8x Training BRIEF OVERALL DESCRIPTION 2

3 Documentation Every installation of LDPS_8x comes with a documentation folder: c:\lumistar(_64)\ldps_8x\documentation including: Documentation on all features in *.doc format A folder of drawings (flow charts primarily) A folder of ICD related software code folders, with sample code LDPS_UserManual Part 1 & 2 in pdf format Individual Lumistar card manuals in pdf format 3

4 Test Configuration The LDPS application is project based The Project File (*.PRJ) specifies configuration files necessary to perform a particular test including: Hardware cards to required for the test configuration Files required to configure the hardware cards, ie. LS-50 (.B50), LS-25 (.LS25V2), LS-70 (.LSDAC), Parameter Database files (.PDB &.PBIN) Derived Parameter and Function files (.DER &.FUN) Display and Display List Files (.DPY &.DPS) Lrrs3x Project List advanced (.LRSXN) 4

5 Project Editor DEMO.PRJ Loads the following files: DEMO.B50 DEMO.PBIN DEMO.DER DEMO.DPS DEMO.DPY The Project Editor can also associate Non Serial files such as LS-25 Receiver, LS- 70 DAC, Special Functions, and Network control of the Lrrs_3x Configuration of the LS-35 & LS-27 or LS-25 cards. 5

6 LDPS_8x Directory Structure C:\Lumistar_64\ Directory Structure Bin folder contains System.dlls Documentation folder contains all documentation including ICDs ans software examples DriverTools folder includes drivers for Lumistar cards System folder contains opetions and configuration information UserTools folder contains Tools and help files 6

7 User Directory Structure The User Configuration Tree Structure is broken into 4 main folders Main Project files are in: ServerFiles ClientFiles Archived Data files are in: ArchiveData Data Reduction files are in: LdrsFiles 7

67 Demo Main PCM Frame Right Click in FR0WD11 and Select: Edit Word FR0WD11 Variable Name LATITUDE TAG FRAME 0 Description WORD 11 Special Order NORMAL Type IEEESNGL Size 32 Bias E+00 Scale E+00 Scale Units DEGREES Frame Start 0 Frame Interval 1 Word Start 11 Word Interval 0 Word Stop 11 Starting Bit 15 Stop Bit 0 Select: New 67

68 Generate LATITUDE Prameter Right Click in indicated area and Modify each area to match parameter definition below: Variable Name LATITUDE Description TAG FRAME 0 WORD 11 Special Order NORMAL Type IEEESNGL Size 32 Bias E+00 Scale E+00 Scale Units DEGREES Frame Start 0 Frame Interval 1 Word Start 10 Word Interval 0 Word Stop 10 Starting Bit 15 Stop Bit 0 Click Accept 68

69 Save Modifications to the DEMO.PDB Click Accept Click OK Right - Click File>Save This will Save the new LATITUDE Parameter into The DEMO.PDB and DEMO.PBIN Databases. 69

70 ReLoad the DEMO.PRJ Load the DEMO.PRJ (see page 22) In the demo_prefilght display, Right Click in the Inertial Widget and select Properties. Click on the first Elipse: ( ) This will bring up the DEMO.PDB list 70

71 Testing the New Latitude Parameter Search for the newly added LATITUDE parameter by typing the name in the Search Window Click to add a Check Mark in the Quick View Mode CheckBox To test the validity of the new Latitude parameter, Double Click The Latitude label In the upper left hand portion of the screen you will see a new Window that shows the calculated value of the parameter, to three significant figures Select the Window and type H for the Hex value of the first 16 bit Word defined in the.pdb O for Octal and B for Binary of the first 16 bit Word 71

72 Using the OTF (On The Fly) Feature Modify LATITUDE Now let s set a Scale Factor that will make the LATITUDE = This is Right Click on LATITUDE and Click Edit Pdbase Settings Right Click on EUC (Scale Factor) Enter the new Scale Factor shown above Click OK 72

73 Using the OTF (On The Fly) Feature Modify LATITUDE 2 Click Accept Then check the new value as before New LATITUDE parameter definition Variable Name LATITUDE Description TAG FRAME 0 WORD 11 Special Order NORMAL Type IEEESNGL Size 32 Bias E+00 Scale Scale Units DEGREES Frame Start 0 Frame Interval 1 Word Start 10 Word Interval 0 Word Stop 10 Starting Bit 15 Stop Bit 0 Note: When you change the parameter definition and then Click Accept, the new Scale Factor and Offset will immediately be used. This is very handy in testing/correcting parameter extraction 73

74 Adding New Parm to Alpha Widget Go to Parm 6 of the aleady open Alpha-Numeric Widget Editor Uncheck the Quick View Mode CheckBox Left Click LATITUDE until you see A white version of this cursor Hold down the Left Button and drag this to the indicated location 74

75 Adding New Parm to Alpha Widget This results in the following Double - Click and change Parameter Label to LATITUDE Click on the Decimal Places drop down and select 5 Finally, Click Accept 75

76 Modify Alpha Widget to Show New Parmeter Select the border of the Inertial Widget on the demo_postlaunch.dpy and stretch it down to show the new Latitude parameter Next go back to the Widget Properties and go to Parm 6 and change the Display Radix to DMS (deg min sec) Change the Value Width to 13 Click Accept When accepted, results in the following display Which produces an interesting Value

77 demo_preflight Display If you want to save this updated Widget, Click the banner then move the mouse cursor slowly down until the additional options appear. Next click the Save button and next time DEMO.PRJ is launched, it will show again 77

78 Closing and Reloading DEMO.PRJ Close the DEMO.PRJ ReLoad the DEMO.PRJ Click DEMO.PRJ 78

79 demo_preflight Display We notice that we Lost the modified Scale Factor (SF) for the LATITUDE parm In order for this SF To be saved, we need to either go To the PDbase Ch4 Editor and make the change, or do what the Software Developer declared As dangerous. I am not exactly Sure why that is, Unless you save an error. 79

80 Edit DEMO.PDB Using OTF Editor Access the OTF Editor using the: demo_prefilght Display, Inertial Widget, Right Click> Properties>Parm 6 Tab>Click the 1 st ( )>Search for LATITUDE> Right Click LATITUDE>Select Edit PDbase Settings>Right Click in Process Definition Area> Select EUC (Scale Factor), enter and Click OK Finally, Click the Save Pdbase Button to save the SF change, then the Accept Button to close the Pdbase Modify Window 80

81 DEMO.PDB Modified by OTF Editor Now Reloading the DEMO.PRJ shows the.pdb is using the newly stored SF 81
