INTRODUCTION
1.3 MIL-STD-1553 Protocol
MIL-STD-1553 is a standard defining a local area network (LAN) originally
developed for and widely used on military aircraft. This digital, command-
response, time-division multiplexing network protocol is also used in many other
military and commercial applications where fast, positive control is required. The
standard defines the handshaking, data formats, and timing requirements of the
protocol as well as the electrical characteristics of the bus and the terminals’
interface electronics. Familiarity with the MIL-STD-1553 databus protocol is
essential to understanding the operation of the Lx1553-5, and it is assumed
throughout this manual that the user is acquainted with this protocol.
1.4 Other Documentation
Besides this manual, Ballard Technology provides other documentation to
facilitate the operation of the Lx1553-5. These include protocol manuals and
information on the software distribution disk.
A BTIDriver API programming manual is available for MIL-STD-1553. This
manual (MIL-STD-1553 Programming Manual for BTIDriver-Compliant Devices)
provides information on the specific protocol and includes basic and advanced
programming instructions for users who intend to write their own software. It
also contains a comprehensive reference for each function.
The software distribution disk accompanying the Lx1553-5 device has example
programs, drivers, and driver installation instructions for various operating
systems, as well as other information, files, and resources.

2. INSTALLATION
This Chapter explains the procedures for installing your Lx1553-5. There are five
steps to installation:
Step 1: Set the Hardware Configuration
Step 2: Insert the Card into the Computer
Step 3: Install the Driver Software
Step 4: Set the Card Number and Test the Installation
Step 5: Connect to the MIL-STD-1553 Databus(es)
After the installation steps are completed, the Lx1553-5 device is ready to
communicate on the MIL-STD-1553 databus(es).
2.1 Step 1: Set the Hardware Configuration
In an ESD safe environment, set the jumpers appropriately for your installation.
The Lx1553-5 contains on-board 75 ohm terminating resistors that may be used
with direct coupling. A second bus terminator must still be used at the other end
of the bus. By having the jumpers in place, the termination resistors are selected.
Figure 2.1 shows the terminating resistor jumpers. The on-board terminating
resistors should not be selected with transformer coupling. For more information,
refer to Appendix A: Coupling and Termination.
Channel 1 Terminated
Channels 1 & 3 Terminated
Figure 2.1—Termination resistor selection jumpers for direct coupling
WARNING
Static Discharge
As with most electronic devices, static discharge may damage or degrade
components on a circuit card. When handling a circuit card, the user
should be grounded (e.g., through a wrist strap). Each circuit card is
shipped in an anti-static bag, and should be stored in a similar container
when not installed in the computer.

2-2 Lx1553-5 User’s Manual
The Lx1553-5/1ST and Lx1553-5/1MT models have twinax connectors which
use the jumpers shown in Figure 2.2 to select the coupling method. Note: These
jumpers should only be used on twinax connector models.
Transformer Coupled Twinax
Direct Coupled Twinax
Figure 2.2—Coupling selection jumpers
2.2 Step 2: Insert the Card into the Computer
In an ESD safe environment, do the following:
•Shut down your computer.
•For PCI cards: Insert the card(s) into an empty PCI slot and secure it to
the case of your computer with a screw.
•For PCIe cards: Insert the card(s) into an empty PCIe slot and secure it
to the case of your computer with a screw. If there is a locking
mechanism on the slot, make sure it is secured.
•Restart your computer.
2.3 Step 3: Install the Driver Software
Drivers allow programmatic control of the Lx1553-5 from a host computer.
The driver installation procedures vary, depending on your computer’s operating
system. These procedures are kept on disk so they can be easily updated as
operating systems evolve. Before proceeding with the installation, find, print, and
review the driver installation procedure for your operating system.
To install the driver software:
•Insert the driver disk in your drive and browse to the folder for your
product
•Print the driver installation instructions located in a README file on the
software distribution disk in a folder specific to your product
•Follow the instructions from the README file
The installation procedure differs for each operating system, but in most cases,
several files are copied to the host computer system and either the system registry
is modified or configuration files are created.
If you encounter problems, have installation questions, or cannot find instructions
for your operating system, please contact Customer Service (see Section 1.5).

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).

3. OPERATION
Now that you have installed the Lx1553-5 in your system, it is ready to be
operated under the control of a software application. Ballard Technology’s
unified API library called BTIDriver, easily operates the Lx1553-5 and utilizes
its powerful interfaces.
3.1 CoPilot
A PC with CoPilot® and Ballard’s Lx1553-5 makes a powerful, low-cost databus
analyzer/simulator. CoPilot interfaces directly with the Lx1553-5, eliminating the
need to write custom software. CoPilot greatly simplifies such tasks as defining
and scheduling bus messages and capturing and analyzing data. CoPilot is a
Windows-based program that features a user-friendly GUI and many timesaving
features. For example, bus messages can be automatically detected, posted in the
hardware tree, and associated with the appropriate attributes from the database of
equipment, message, and engineering unit specifications.
CoPilot users can quickly configure, run, and display the activity of multiple
databuses in a unified view. Data can be observed and changed in engineering
units while the bus is running. The Strip View graphically illustrates the history
of the selected data values. Data can also be entered and viewed as virtual
instruments (knobs, dials, gauges, etc.) that can be created by the user or

OPERATION
3-2 Lx1553-5 User’s Manual
3.2 User Developed Software
With only a few function calls, a program can operate the Lx1553-5 and process
messages to and from the avionics databuses. Functions include routines for
transmitting, receiving, scheduling, recording, data manipulation, and time-
tagging bus messages. Although most tasks require only a few API calls, the
comprehensive API library includes a broad range of functions for specialized
needs.
Example programs are included with the API on the software distribution disk.
Detailed information about API functions and instructions on programming for the
Lx1553-5 are found in the MIL-STD-1553 Programming Manual for BTIDriver-
Compliant Devices. You can use this manual to learn how to create custom
applications for any of Ballard Technology’s BTIDriver-compliant interface
products.

4. TROUBLESHOOTING
4.1 LED Indicators
There are two LEDs on the front panel. The red LED and the green LED can be
controlled via software using the API functions BTICard_ExtStatusLEDWr() and
BTICard_ExtLEDWr() repectively. For more information on this function,
consult the MIL-STD-1553 Programming Manual for BTIDriver-compliant
Devices API programming manual.
4.2 Lx1553-5 Test Program
There are a few options available to verify that the Lx1553-5 is working
correctly.
•Test Program: To test the device, run the test utility distributed on the driver
disk for the particular host operating system. For example, on a Windows
host computer run the BTITST32.EXE program included on the Windows
Driver disk to verify the installation and hardware operation. These test
utilities will display a passed or failed message and provide detailed
information about the device hardware.
•API Test Function: The BTIDriver API includes the BTICard_CardTest()
API function to verify operation of the hardware from a user developed
application. It is advisable to include a call to this function at the beginning
of an application. For more information on this function, consult the MIL-
STD-1553 Programming Manual for BTIDriver-compliant Devices API
programming manual.
