The XXDBAWin software allows to control the VM-DBA through both the on-board USB
interface as well as through the VME bus when using the WIENER VM-USB controller as
the VME master. Please refer to the VM-USB manual for programming and use of this
controller.
In case of VM-DBA operation through it’s USB port only the “VM/DBA” tab for setting
and reading data as well as the “Flash Operations” tab for firmware upgrades are used. All
other tabs are disabled. Please see chapter 7 for firmware upgrade instructions.
Using the XXDBAWin software it is possible to configure the display modes / options
(General setup) and define the VM-DBA interrupt settings (IRQ setup).
The VME bus analyzer can be configured by defining the trigger conditions as well as time
base and ranges. When done the trigger can be activated and it is possible to read back data
when available. XXDBAWin provides a graphic display of the bus lines as a function of
time. All bus lines to be shown on the waveform display can be selected and the waveform
histogram is shown automatically.
