All AIS Class A Transponders have a special “Pilot Plug” that is intended to allow a Commercial Pilot to quickly and reliably connect their laptop PC to the Class A Transponder when they arrive onboard.
Often on larger vessels the normal 1-2m length of the Pilot Plug can make connecting to the vessels Class A transponder difficult. Therefore, as most Pilot Plug cables use a USB interface, that has a limit of 5m, extending the cable can be problematic.
The Digital Yacht Pilot Plug extension cable, extends the NMEA0183 wiring and not the USB wiring. As a result, this makes it possible to extend up to 10m (or more). Plus the length of the existing Pilot Plug cable.
“The AIT2500 is a full function Class B+ SOTDMA AIS transponder with NMEA 0183, NMEA 2000 and USB data outputs. It is supplied with a GPS antenna.”
“HA156 is a 15cm VHF heliflex antenna, this is specifically tuned to AIS (162MHz) frequencies for optimal performance.”
“Patented zero loss technology lets you share your main VHF antenna with the VHF radio, FM radio and AIS. Compatible with transponders and receivers.”
