Comments
The
Gx6384Initialize
function verifies whether or not the GX6384 board exists in the specified PXI slot. The
function does not change any of the board settings. The function uses the HW driver to access and program the
board.
The Marvin Test Solutions HW device driver is installed with the driver and is the default device driver. The
function returns a handle that for use with other Counter functions to program the board. The function does not
change any of the board settings.
The specified PXI slot number is displayed by the
PXI/PCI Explorer
applet that can be opened from the Windows
Control Panel
. You may also use the label on the chassis below the PXI slot where the board is installed. The
function accepts two types of slot numbers:
A combination of chassis number (chassis # x 256) with the chassis slot number. For example, 0x105 (chassis 1
slot 5).
Legacy nSlot as used by earlier versions of HW/VISA. The slot number contains no chassis number and can be
changed using the
PXI/PCI Explorer
applet (1-255).
The returned handle
pnHandle
is used to identify the specified board with other GX6384 functions.
Example
The following example initializes two GX6384 boards at slot 1 and 2.
SHORT nHandle1, nHandle2, nStatus;
Gx6384Initilize (1, &nHandle1, &nStatus);
Gx6384Initilize (2, &nHandle2, &nStatus);
if (nHandle1==0 || nHandle2==0)
{
printf(“Unable to Initialize the board”)
return;
}
