The interconnect data that follows is for the ARINC 615 Portable Data Loader (PDL) connector J1 located
on the front panel of the transponder. The transponder’s operational software can be updated (upload to
transponder) through this connector. In addition, the contents of the fault log can be extracted for analysis
and troubleshooting (download from transponder).
The 53 pin front panel PDL connector contains both an ARINC 429 high speed bus interface for connection
to an ARINC 615 PDL, and an RS--232 bus interface for connection to a personal computer (PC) through a
standard serial port. Only the pins used by the transponder are shown.
The PDL standard interface cable should be 10 feet in length (3 meters) and be terminated with a connector
type MS27473T--18A--53S at the data loader end and connector type MS27473T--18A--53P at the
transponder end.
