PLB with GPS test support such as a ACR RescueLink PLB Once a valid message is received with position information the configured NMEA sentence with updated position and checksum information is sent out the serial port at 4800 N 8 1 once every second until power to the 406 LER is removed Be sure to check that the beacon ID is first added to the database or the preferred NMEA configuration is being used NOTE Any configured NMEA sentence MUST begin with a character and end with a Page 17 of 28 character Also if the and characters are not added to the NMEA sentence then NO DISTRESS POSITION WILL BE ADDED TO THE OUTPUT make sure a system has always been deployed with these characters in place as shown in the example above Preferred NMEA Output Configuration Although any NMEA output sentence can be configured the following NMEA configuration should be used if possible available only from firmware v1 19 onwards GPWPL 4807 038 N 01131 000 E or SGPWPL 4 The use of the waypoint NMEA sentence as shown above with the character before the terminating character allows a special mode of waypoint operation When the character is used the waypoint ID is rewritten by the 406 LER depending on the nature of the 406 transmission The NMEA output when using the character is as follows For any transmission with a valid position that is matched in the database GPWPL 4807 038 N 01131 000 E MOB 1 The
