3.5.17NMEA Operation
When an Optional Full Function Handset is installed enabling the Class “D” DSC functionality, the RAY215E 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 position data, it provides alerts urging you to find and correct the fault. The optional Full Function Handset enables you to manually input this data using the L/L ENT function, as described in Section 4.7.3.2.
Note: NMEA position data can be communicated only when an optional Single or Second Station Full Function Handset, enabling Class “D” DSC functionality, has been installed.
If a GPS device is not connected via NMEA, the radio emits a
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 accepted and the NMEA indicator is displayed on the LCD.
If no GPS signal is detected on NMEA after the 1 minute monitoring period, a
If at a later time valid data is received on NMEA, the data is accepted and the NMEA indicator is displayed solid (no longer flashing).
Operation When the Signal is Lost or Becomes Invalid
If positional data that was previously detected becomes invalid or is no longer detected, the radio monitors the NMEA line for 1 minute for it to be restored.
If a signal is restored on the NMEA line and the radio determines the data is valid, the data is accepted and the NMEA indicator returns to a solid state (not flashing).
