Network connections ContentsConnections overviewHandset station connectionA Wired handset can be connected to each Handset station connection (HS 1 / HS 2). Your radio is supplied with the equipment to create a full handset station (i.e.: Wired handset, Adaptor cable and Passive speaker). Additional accessories can be purchased to create a second wired handset station.Wired speaker connectionA wired speaker can be connected to a wired handset station using the RCA audio connector, available on the Handset adaptor cable.Connecting GNSS (GPS) and VHF antennasYour radio requires a VHF antenna to function as a radio. If you intend to use the radio’s internal GNSS (GPS) receiver then you will also require a GNSS (GPS) passive antenna to be connected. The antenna connections can be protected so that they cannot come into contact with any grounded bare metal. This is especially important when installing the radio on metal structure.Wireless hub connectionThe Wireless hub connects directly to the Ray90 / Ray91’s Hub connection.Wireless handset connectionsThe Wireless handset connects wirelessly to the Wireless hub, and the Wireless speaker connects wirelessly to the Wireless handset.Previous topic: MountingNext topic: NMEA 0183 connection
