Operations

If a signal is restored on the last detected line (SeaTalk or NMEA) and the radio determines the data is valid, the data is input, the NMEA indicator remains illuminated, and the radio re-enters normal operation mode.

However, if no signal is detected, the NMEA indicator flashes and a 5- second-long staccato alert tone is emitted. The last received positional data is retained in memory and can be viewed in the NAVSTAT screen. The message NO GPS appears in NAVSTAT in the position where the type of device used to be. The NMEA indicator continues to flash until valid positional data is received. If valid positional data (from the same source) is later restored, the NMEA indicator is again displayed solid.

Operation When No Signal Detected for 4 Hours

If no valid positional data is received or input manually within 4 hours of the previous alert, the NMEA indicator continues to flash and the staccato alert tone is again emitted. This pattern is repeated every 4 hours if no positional data has been detected. If no manual input was made during the previous 23.5 hours, all the position fields are set to 9’s and the time and date fields are set to 8’s.

3.5.25 SeaTalk Operation

The RAY230/RAY230E can receive SeaTalk position and time information from any SeaTalk capable device. As with NMEA data, if the position information becomes invalid or is not present, you will be prompted to manually input position data.

3.5.26 Digital Selective Calling (DSC)

The Digital Selective Calling (DSC) protocol is a globally applied system used to send and receive digital Distress calls as well as Individual and All-Ships calls on channel 70, the dedicated DSC channel for Marine VHF. DSC operation includes the following:

1.Transmitting/Receiving an Individual Call

2.Transmitting/Receiving a Group Call

3.Transmitting/Receiving an All Ships Call

4.Transmitting/Receiving a Distress Call

5.Receiving a Distress Relay Call

Actually, the RAY230/E has a separate receiver exclusively for Channel 70 so that even if receiving under normal operation, the unit can quickly switch over to Channel 70 upon receiving a DSC signal. When the DSC signal is received, the unit performs the corresponding operation. If the radio is transmitting, however, receiving on Channel 70 is disabled.
