LP1553-5 (PCI) / LE1553-5 (PCI Express)

The LP1553-5 (PCI) and LE1553-5 (PCIe) are personal computer expansion cards for communicating with MIL-STD-1553 systems. These feature-rich interfaces provide programmable data buffers and deep built-in memory. Models offer 1 to 4 dual redundant MIL-STD-1553 channels, 16 input/output avionics level discretes, and IRIG time synchronization/generation. MIL-STD-1553 capability includes BC, RT, and/or Monitor. Avionics discretes can be used as general purpose I/O or linked in hardware to 1553 databus activity as triggers or syncs.

The Lx1553-5 model line supports maximum data throughput on all 1553 interfaces. Each channel is independently configurable as Bus Controller, Remote Terminal(s), and/or Bus Monitor. Messages can be captured by a sequential monitor for all channels, or via RT map monitoring. Notification of databus activity is handled through the on-board Event Log, which can be processed by polling or via an interrupt. To dramatically reduce the host CPU processing, the sequential monitor has a DMA mode that automatically moves records to host memory through PCI/PCIe bus mastering.


  • Memory: 32 MB on-board memory
  • DIO: 16 avionics level inputs/outputs
  • IRIG: A or B, AM, PWM and PPS modes


  • Size: 6.9 x 4.2 in. (both PCI and PCIe)
  • Weight: 4.55 oz
  • Channels are dual redundant, bus A and bus B
  • Single-function channels are software configurable as BC, 31 RTs, or Bus monitor
  • Multi-function channels are software configurable as BC, 31 RTs and Bus Monitor
  • Channels support transformer or direct coupling with jumper-selectable on-board termination


The Lx1553-5 products are half size compliant cards. Avionics transition cabling is available from the unit's I/O connectors to standard 1553 cable connections. The universal PCI or PCI Express interfaces available make the Lx1553-5 compatible with virtually all modern desktop, rackmount, and server computers.

The Downloads section contains data sheets with complete information for Lx1553-5 products.


The easiest way to use the MIL-STD-1553 functionality of your LX1553-5 board is with CoPilot, Ballard's Windows-based software. CoPilot is an intuitive, interactive program that simplifies the testing and simulation of MIL-STD-1553 systems. In CoPilot, you can simulate the Bus Controller, up to 32 RTs, and monitor, record, and export bus activity. Data can be entered and displayed in engineering units and data definitions may be saved to the 1553 database. CoPilot features include virtual instruments, strip charts, moving map displays, scripting, and software playback mode. CoPilot also supports ARINC 429, ARINC 708, ARINC 717, ARINC 664/AFDX® protocols, and serial. You can add CoPilot at anytime. However, you will receive a discount when you purchase CoPilot bundled with the hardware.

Alternatively, users can develop their own applications using the included BTIDriver API. 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, time-tagging, and data manipulation.


Driver software is included for Windows®, Linux®, VxWorks®, INTEGRITY®, LabVIEW, and LabVIEW-RT. Contact Ballard for availability of drivers for other operating systems.
