The TechSAT A429PCI-2G2 is a multichannel ARINC 429 PCI carrier module that accommodates up to four IndustryPack (IP) modules on a single short or full-length PCI board. It delivers up to 4 transmit and 8 receive ARINC 429 channels, making it ideal for avionics maintenance, testing, integration, and troubleshooting in both mobile and stationary field environments. The carrier integrates on-card computing resources, avionics discrete I/O, Tx-Rx wrap-around relays, and inter-IP synchronization signals to offload real-time protocol handling from the host CPU.
Technical Specifications
• ARINC 429 Channels: Up to 4 Tx and 8 Rx channels (2G2 version)
• IP Module Support: Accommodates up to 4 intelligent ARINC 429 IP modules compliant with IndustryPack standard
• Microcontroller: Integrated 20 MHz Siemens C165 with 1 MByte RAM and 1 MByte EEPROM per IP module
• Data Interface: SCSI III DB68 connector for all ARINC 429 I/O lines
• Power Consumption: +5V, 2.3 A (with 4 A429IPM modules; varies by installed configuration)
• Dimensions: 186 mm maximum length (2G2 version)
• Operating Temperature: 0°C to 55°C
• Storage Temperature: −10°C to 85°C
• Humidity: 5% to 95% non-condensing
– Key Features
• Distributed IP module architecture eliminates single-point failure and optimizes real-time performance
• Vendor-neutral IndustryPack compliance enables mixed-vendor module configurations
• On-card wrap-around relays support internal loopback testing and validation
• Inter-IP synchronization signals maintain channel timing coherence across modules
• Small form factor (maximum 186 mm) enables deployment in space-constrained avionics racks
– Typical Applications
Aircraft avionics system integration and validation, line maintenance test stands, unmanned aerial vehicle (UAV) data acquisition, mission equipment checkout, and legacy avionics troubleshooting.
– Compatibility & Integration
Binary-compatible with TechSAT A29PCC PCMCIA and A429EPC ISA-bus boards; legacy applications require no modification. Interface libraries (DLLs) support MSVC, Visual Basic, Delphi, LabVIEW, and HP VEE. Drivers available for Windows XP, 2000, ME, NT, 9x, and Linux. Optional A429BAST Bus Analyzer & Simulation Tool provides protocol decoding and message injection across all TechSAT ARINC 429 products.
