Main and AUX high speed input/output ports
The Transponder has two high-speed communication ports. The ports are identical, the same
information is input and output on these ports. All information received and transmitted on the
VHF link will be reflected as correct IEC 61162 sentences. All error messages will also be
transmitted.
The Main port will primarily be used to connect external equipment such as ECDIS and ARPA
or another navigation information display system.
The AUX port will primarily be used for connection to the “pilot plug” - a connector installed on
the bridge near the pilot operation position so that the pilot can connect a Personal Pilot Unit,
which is normally a laptop computer with the pilot’s navigational software installed.
