INSTALLATION
2.3 Step 3: Set the Card Number and Test the Installation
You must set a card number on the controlling computer for software to uniquely
identify each PCIe card.
Since many Ballard BTIDriver™-compliant hardware devices (e.g., OmniBus II
PCIe/PXIe cards) can be concurrently connected to the same computer, software
running on a given computer uses a unique card number to designate which hard-
ware device is being accessed. If you have only one BTIDriver-compliant device
connected to the computer, it is recommended that you set it to card number 0
because the example programs included with the driver software assume a card
number of 0. After the card number has been set, you can then test the PCIe/PXIe
card.
In Windows, the BTITST32.EXE test program can be used to assign and manage
card numbers and to test the PCIe/PXIe card (and other BTIDriver-compliant
devices). The test program discovers all connected BTIDriver-compliant devices
and displays important information about each device such as card number,
configuration, serial number, and assembly part number. Running the test
sequence verifies both the device hardware and the interface between the device
and the computer. If the program does not detect any faults, it displays a “passed
test” message.
This program and a README file with instructions are found in the Windows
Test subfolder on the software distribution disk:
PCIe: OMNIBUS DRIVERS OMNIBUS_II_PCIE TEST
PXIe: OMNIBUS DRIVERS OMNIBUS_II_PXIE TEST
Note: The Windows test program may be used at any time to determine
or reassign the card number.
If you need further assistance, contact Ballard Technology’s Technical Support
(see Section 1.5).
2.4 Step 4: Connect to Databus(s) I/O
Connect the databuses to the PCIe/PXIe card according to the pin assignment
tables in Chapter 7. Be sure to follow the coupling and termination guidelines
discussed in Appendix A.
Connection of the ground pin(s) to the end system(s) is necessary for proper op-
eration of ARINC 429, ARINC 717 and the discrete I/O, and is recommended for
MIL-STD-1553. There is no need to terminate unused signals, and do not con-
nect the reserved pin(s).
