ASTi Link 16 Diagnostic Tool for Windows

The Link 16 Diagnostic Tool (LDT) is a network analysis tool capable of decoding Link 16 formatted transmitter and signal PDUs per the SISO Link 16 Specification. The tool provides the ability to view and examine all Link 16 traffic detected on the connected network. Another feature of the tool is the ability to define signal and transmitter PDU data to transmit over the network.

A significant feature of the tool is the ability for the user to define simulator names instead of using simulator DIS ID numbers and IP addresses. This allows the user to easily view who is and isn't present on the network.

The LDT is capable of showing the details of the Link 16 Tx and signal PDUs. When running Link 16 on the DIS network, this is an essential tool that provides insight into what is going on in the Link 16 network.


LDT main features include:

  • The ability to define separate Tx and signal PDU networks
  • The filtering capabilities based on Exercise ID, Timeout value, Terminal Mode, Net Sync ID, Signal PDU Type, Timeslot Type, etc.
  • CVSD audio monitoring
  • Simulator name definitions for easy sorting and understanding
  • Detect duplicate radios
  • Define and generate Tx and Signal PDUs for a single Link 16 terminal
  • Decode key Link 16 PDU parameters in an easy readable format
  • Decode key Link 16 Signal PDU parameters in an easy readable format (including details of the 8 message types)
  • Understand what is going on in your Link 16 network

The central 'workstation' of the tool revolves around the Link 16 transmitter list. On initial startup this list will display the Link 16 transmitters on the connected network. This view provides information for each transmitter including the current status, simulator name, transmitter ID, etc. The current transmit state of the Link 16 transmitters are reflected in real-time. If a radio does not issue a data PDU within the user defined time-out period then it will be tagged as 'timed out.' The user can get a snap shot of the network data history. The user may reset the list at any time by using the 'refresh' button. This will rebuild the list from new and update the network status.
