Raymarine Ray215 manual Nmea Operation

4-18 Operation with a Full Function Handset

To start Tri-Watch mode, select the Working Channel then press the FUNC key followed by the MON/TRI key. The Working Channel appears on the 7-segment display, the Priority Channel appears on the right-most portion of the dot matrix display, and the Weather Channel appears on the left- most portion of the dot matrix display.

To end Tri-Watch mode at the current channel, press the MON key or the CLR key. If Tri-Watch mode is initiated at Channel 70, the operation is cancelled and an error alert tone sounds.

4.4.15NMEA Operation

The RAY215 can receive valid position and time information, which are transmitted during a DSC Distress call. This data can be communicated via NMEA 0183 from a GPS, fishfinder, radar, or any device that outputs GPS sentences. If the radio does not detect the positional data, it provides different alerts urging you to find and correct the fault or manually input the data using the radio’s L/L ENT function, as described in section 4.5.3.2. Current valid positional data, whether from external device or manually input, can be viewed using the NAVSTAT Operation described in section 4.5.2.

If a GPS device is not connected via NMEA, the radio emits a 5-second- long staccato alert tone and flashes the NMEA indicator 2 minutes after power up. This occurs every time the unit is turned on. The alarm is required by safety regulations and cannot be disabled.

Operation at Power Up

At power up, the radio monitors the NMEA line for 1 minute. If a signal is detected on NMEA, the radio determines whether the data is valid. If valid, the data is input, the NMEA indicator is displayed on handsets, and the radio enters normal operation mode.

If no GPS signal is detected on NMEA after the 1 minute monitoring period,

a5-second-long staccato alert tone is emitted and the NMEA indicator flashes. All the position fields are set to 9’s and the time and date fields are set to 8’s. The message NO GPS appears in the NAVSTAT screen, although no positional data is displayed.

If at a later time valid data is received on NMEA, the data is input, the NMEA indicator is displayed solid (no longer flashing), and the radio enters normal operation mode.
