5.Running the GeoMapper Application
5.1.Who needs a Geographical Map of Modules
The GeoMapper application gives the user the possibility of telling the Acqiris driver crucial details of the physical position of modules when this information cannot be deduced directly. It allows the driver to correctly adjust trigger and clock delays between the different modules of an ASBus
The GeoMapper application has been implemented as a Wizard with the goal of learning the physical position of each module of a
NOTE: The unusual slot numbering convention of the CC121 is documented in the CC121 CompactPCI Crate User Manual. The CC10X crates have a simpler slot numbering convention that the Acqiris driver already takes into account. CompactPCI Crates from other manufacturers represent an unknown element.
NOTE: The GeoMapper is of use for some ASBus systems in CC121 crates and, perhaps, crates from other manufacturers. CC121 crate configurations with both an Acqiris acquisition module in one of the last 7 slots and with the PC running under Windows 2000 or XP will not need the GeoMapper. Users who do not need GeoMapper do not need to read this chapter any further.
5.2.When should the GeoMapper Application be used
The application needs to be used whenever the bus or slot configuration of the system changes in a fundamental way. The most obvious trouble symptom is that an expected
Modules are not contiguous in ASBus combination ASBus Candidate Modules not on same bus 'AcqGeo.map' file is invalid or corrupted
ACQIRIS_ERROR_MODULES_NOT_CONTIGUOUS ACQIRIS_ERROR_MODULES_NOT_ON_SAME_BUS ACQIRIS_ERROR_INVALID_GEOMAP_FILE
In all of these cases the GeoMapper application should be run to ensure that the map file is up to date.
If desired the GeoMapper application will generate a default configuration in which it allows the driver to make all of the choices. This is done by specifying "None (Disable GeoMap)" as the desired configuration in "Step1: Crate count" of the application.
5.3.How to run GeoMapper
After software installation you will find GeoMapper in the AcqirisApp directory of the installation directory. After being started the program will learn about the Acqiris devices present and then show a screen like the one below:
The choice of the number of crates ranges from None up to the number of bus segments that the driver has found containing Acqiris modules. If you choose None and save the resulting AqGeo.map file the system will behave in its natural way without any additional user provided information. If you want to give the driver information on the physical position of modules you should select the appropriate number of crates. If the number of crates does not
