10.8NMEA DEPTH, WIND SPEED, TEMP AND SOG TREND PAGES

When the GPS chartplotter is connected to the optional Black Box Fish Finder or a Digital Depth Sounder, Wind Speed/Direction, Speed Log with Temp with NMEA output the chartplotter is capable of show Trends in the data from the device.

To select a NMEA Trend Page:

1.Press [MENU], move the ShuttlePoint knob to highlight NMEA DISPLAY.

2.Move the ShuttlePoint knob to select DEPTH TREND, WIND SPEED TREND, TEMP TREND or SOG TREND.

10.9VHF DIGITAL SELECTIVE CALLING

Digital Selective Calling is a semi-automated method of establishing a VHF radio call. DSC had also been designated as part of the Global Maritime Distress and Safety System (GMDSS). It is planned that DSC will eventually replace aural watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts.

This new system allow mariners to instantly send a distress call with GPS position (when connected to the transceiver) to the US Coast Guard and other vessels within range of the transmission. DSC will also allow mariners to initiate POSITION Request, POSITION Send calls to or from another vessel equipped with a DSC transceiver.

STANDARD HORIZON VHF Marine Radios with Digital Selective Calling are able to be interfaced with the GPS chartplotter which feeds GPS data to the VHF and listens for DSC calls from the VHF. By connecting a few wires between the STANDARD HORIZON VHF and the GPS chartplotter it will receive:

1.a vessel that has transmitted a DSC Distress call

2.a vessel that has transmitted a DSC Position Send Call

3.The position of a vessel that transmitted a DSC Position Request Call

10.9.0 Interfacing

To take advantage of these functions the plotter must be interfaced (wired) to a STANDARD HORIZON or compatible DSC VHF.
