INSTALLATION
2.4 Step 4: Set the Card Number and Test the Installation
You must set a card number on the controlling computer for software to identify
the Lx1553-5.
Since many Ballard BTIDriver™-compliant hardware devices (e.g., Lx1553-5)
can be concurrently connected to the same computer, software running on a
given computer uses a unique card number to designate which hardware 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 Lx1553-5.
In Windows, the BTITST32.EXE test program can be used to assign and manage
card numbers and to test the Lx1553-5 (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 (Lx1553-5 WINDOWS TEST) on the software distribution
disk.
Note: The Windows test program may be used at any time to determine
or reassign the Lx1553-5 card number.
In Linux, card numbers are automatically assigned as they are discovered by the
kernel module on the PCI/PCIe bus. The card number is determined by the bus
sequence.
In other operating systems, testing and card number management are handled
differently. Example programs on the software distribution disk illustrate
concepts for managing card numbers and testing hardware. In many cases, these
example programs can be recompiled or easily modified for various operating
systems. Instructions on assigning card numbers can be found on the README
file found on the software distribution disk. If you need further assistance,
contact Ballard Technology’s Technical Support (see Section 1.5).
2.5 Step 5: Connect to the MIL-STD-1553 Databus(es)
The Lx1553-5 has either two 60-pin LFH connectors or two Twinax connectors.
Connect the databuses according to the pin assignment tables in Chapter 6.
Connection of the ground pin(s) to the end system(s) is necessary for proper
operation of MIL-STD-1553 and the discrete I/O. There is no need to terminate
unused signals and do not connect the reserved pin(s).
