Application Scope

The ARINC 615A Configurable Data Loading Engine (CDLE)™ is a fully configurable 615A data loading engine plug-in. The CDLE™ supports full ARINC 615A –1/-2 compliant data loading of Loadable Software Aircraft Parts (LSAP) for data loading of avionics LRU/LRMs via Ethernet per the ARINC 615A standard. It provides a development tool and code source for integration of a 615A data loading capability into an existing or new LRU/LRM design.
 

Feature Highlights

  • ARINC 615A compliant services
  • Multithreaded TFTP Engine
  • Static Configuration via command line parameters and configuration files
  • Dynamic Configuration via LSAP Manager SETUP call
  • Small Memory Footprint
  • CDLE™ Manager GUI for development and testing

 

LSAP Manager Interface

The CDLE™ LSAP Manager Interface is a simple and scalable interface to a user-provided LRU-specific Parts Manager. It offers all functionality for supporting ARINC 615A requests. The LSAP Manager runs as external application allowing updates of the LSAP Manager not affecting CDLE™ and vice versa.

Features:

  • SETUP command: provide system information for CDLE™ at startup with parameters such as IP address, THW_ID, etc
  • INFO command: report installed LSAP Parts
  • INSTALL command: install software part on LRU, provides means for configuring CDLE™ installation mode
  • DOWNLOAD command: query and locate downloadable items
  • Allows LSAP Manager to be written without ARINC 615A/665 parsing capabilities
  • ABORT/CANCEL signal: allow the LSAP Manager to stop current command in case of ABORT/CANCEL from CDLE™ or from the host data loader.
  • Cyclic Heartbeats: provide the CDLE™ and host data loader with feedback on status of LSAP Manager operation

 

Media Installation Development Engine Plug-in

Also available from TechSAT is an ARINC 655 media installation engine plug-in for unpacking and installation of ARINC 665 files. ARINC 665 compliant media sets delivered from the CDLE™ are unpacked to a distributable structure and placed in locations where stub functions can access them for parts installation.
