Integrated dual channel AIS (Automatic Identification System) Receiver

The GX2400GPS integrates a dual channel AIS receiver to display real-time AIS vessel information directly on the LCD display. The GX2400GPS allows you to contact an AIS ship directly using DSC function, show your vessels position in relation to AIS targets and alert you when an AIS ship may be approaching too close to your location by CPA/TCPA alarms. «Target list» and «Danger list» display also provide to avoid collision with vessels even in crowded areas, bad weather and night time.

NMEA2000 Compatibility

The integrated NMEA2000 interface supports PGN (Parameter Group Number) Navigation, AIS report, GPS and DSC functions. Simply connect the transceiver to the NMEA2000 network to complement your system with radio and DSC functions.

ITU-R M.493-15 Class D DSC (Digital Selective Calling)

The GX2400GPS is capable of DSC (Digital Selective Calling) Class-D operation with its separate Channel 70 receiver, which allows DSC calls to be received even while listening to communications on another channel. When the DSC Distress function is activated, a digital MAYDAY distress message is transmitted, including the vessel MMSI identification,

Nature of Distress and includes accurate Lat and Long position information with accurate date and time helping to facilitate an immediate response. Other DSC Call types supported include Individual, Group, Urgency, Safety, Position Reports and Test Calls.

Integrated 66 channel Internal GPS Receiver

With the internal high-performance 66 channel GPS receiver, SBAS satellites (WAAS/EGNOS/MSAS/ GAGAN) can be received. The GPS data is available for AIS vessel information, DSC calling, position sharing, waypMicrophone RAM4W SSM-71H - GX2400GPSoint navigation, and navigation to DSC distress calls, all performed with a few simple steps.

Optional RAM4W or RAM4 Microphone for Second Station

The optional RAM4W (Wireless Remote access microphone)*l or RAM4 (Remote access microphone) are capable of controlling most of the radio functions including DSC, therefore it may be used as a second station and an intercom. The RAM4W can be connected via wireless access point SCU-30. And the RAM4 can be located up to 23 feet (7m)*2 away from the transceiver.

*1 Optional SCU-30 wireless access point required *2 Optional CT-100 extension cable required

Noise Canceling for both Transmit and Receive audio

Equipped with the noise cancellation function by DSP (Digital Signal Processor) to reduce ambient noise for both transmission and reception, enabling clear communication. In addition, the AF PITCH CONTROL function can be adjusted to the optimum receiving audio level (High/Low frequencies) that is easy to hear according to the noise conditions.

Selectable Display Mode (Night Mode Display)

The display is selectable between DAY mode and NIGHT mode. The NIGHT mode display improves visibility at night by inverting the black and white dots of the display from the DAY mode.
