6.4.9 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 is normally connected to the display unit, where it is looped through to drive the
Pilot Plug connector on the display unit. If a Pilot Plug is not required, the AUX port may be
disconnected from the display (at the transponder end) and may then be used as an additional
Presentation Interface (PI) port.
