2.1 Introduction to Navtex
2.1.1 Overview
The SAILOR 6390 Navtex Receiver receives Navtex messages on the international Navtex
frequencies 490 kHz, 518 kHz and 4,209.5 kHz. It can hold 2000 messages per frequency.
Messages are not affected by a power cycle. If not tagged to avoid deletion, messages are
cleared from the message log after 66
1
hours. You can customise which stations to receive
messages from and which message types you want to receive. The unit has an alarm relay
which is only activated if a message of category D is received (i.e. SAR, Mayday relay, Pirate
attack etc.). The SAILOR 6390 Navtex Receiver is always on when powered. With its LAN
interface the transponder and the display can be separated, giving access to the Navtex
information available where it is needed.
The SAILOR 6390 Navtex Receiver is delivered as a black box receiver which can either be
connected to the SAILOR 6004 Control Panel, a 7" touch screen, or used as a standalone
unit for integration with an INS, supporting NMEA0183. A printer can be connected to the
receiver.
The SAILOR 6390 Navtex Receiver is approved according to GMDSS (EU Marine Equipment
Directive).
