Tiny SeaTalk NMEA Bridge with galvanic isolated RS232

• The easy way to bring SeaTalk instrument data to your boat computer and navigation software.
• The easy way to send data from your navigation software to SeaTalk instruments.
• Protects your equipment by full galvanic isolation between SeaTals and computer power
• May pluged direct to the computers using a provided connection cable
• Extended update function. Software may be updated by user anytime without any wiring changes.

Galvanic isolation protects your board computer and your instruments.
Galvanic isolation is especially interresting if your have different power sources for the board computer and the instruments.
I.e. the board computer can be connected to shore power, if you have different batteries for computer and instrumentation. It also protects your computer and your instruments in case the SeaTalk Nmea Link should accidently be connected with reversed polarity.
Alltogether - It simply makes the whole system more more reliable and safer.

This tiny SeaTalk NMEA Link has :

• 1 * SeaTalk port
• 1 * RS232 port
• 1 * 12 Volt power supply

SeaTalk data will be translated to standard NMEA sentences, that can be used by any normal software on the pc. ( SeaClear, Fugawi, Offshore Navigator and all the others. )

Functions :

Read SeaTalk -> Send to NMEA port

Read NMEA -> Send to SeaTalk
