2.3.1 AFDX Connection
The AFDX connection is done via a standard RJ45 Ethernet connector located on the
Front panel of the AXC-FDX-2 module.
2.3.2 Trigger, Discrete and IRIG Connector
For multi-channel time tag synchronization an input for the on-board IRIG-Decoder and
an output for inter-board synchronization is available. The output format is an AIM
specific IRIG coded signal.
The connector also provides four Trigger input/output signals, which can be used with
dedicated applications. Additional up to 4 users definable Discrete I/Os are placed on
the connector.
This connector is implemented by a 3 row 15pin, female HD-SUB Connector. Technical
Details about the Trigger and Discrete lines can be found later in this document.
