Hint
A simple case: 
NMEA datas have to be transmitted to the PC.
? NMEA datas are existing and there are no voltage peaks expected.
! According to the manual solder a RS232 plug  to the NMEA Data cable and plug it in the PC.

Hint
To a  NMEA output you can normally connect 2-3 NMEA inputs parallel and use some cable (3-6m) inbetween without problems.

Here you can find a solution for your problems: 

Input	Output	Solution
1 x NMEA + Voltage peaks	RS232 PC	Converter 1600
1 x NMEA + Voltage peaks	USB PC	Converter 1610
1 x NMEA + long cables	1 to 4 x NMEA / RS232 PC	Distributor 1324
1 to 2 x NMEA	1 x NMEA / RS232 PC	Multiplexer
1 to 4 x NMEA	1 x NMEA / RS232 PC	Multiplexer
1 x SeaTalk	1 x NMEA / RS232 PC	Konverter ST
2 x SimNet	1 x NMEA	Simrad AT10

 

NMEA <=> RS232 PC - Converter 1 For the transfer of data between PC and GPS or board instruments. The converter protects the PC from dangerous potential differences and interference peaks on the data cable. Data input and output are galvanically parted among eachother as well as to the board voltage.  The converter is made for a 12 Volt bord network.   Converter 1   order here

 

NMEA <=> USB PC - Converter 2 To transfer data between the PC and the GPS or board instruments. The converter protects the PC from dangerous potential differences and interference peaks on the data cable. Data input and output are galvanically parted among eachother as well as to the board voltage.  PC driver for Win 98, ME, 2000 and XP are enclosed. The converter doesn`t need an extra voltage supply.   Converter 2   order here

 

NMEA => 4 x NMEA - Distributor 1 to 4 New For NMEA-networks on yachts, where the data are distributed to various NMEA-receivers (Laptop / DSC radio receiver / EPIRB ...) or if the data cable between the instruments is very long (> 3m).  A four way-NMEA-Buffer, wich transforms NMEA-signals of an output in four outputs with a higher loading capacity and therefore protects the output from overload. The distributor is made for a  9-36 Volt board voltage.   Distributor 1 to 4   order here

 

2 x NMEA => 1 x NMEA - Multiplexer 2 to 1 For NMEA-networks on yachts,where the data have to be transmittet from various NMEA-receivers (GPS / log / echo sounder / compass ...) one after the other to the  Laptop or in the board network.  A two way NMEA-multiplexer, that transforms 2 NMEA input signals to one NMEA data output. The multiplexer is made for a 12 Volt board network.   Multiplexer 2 to 1   order here

 

4 x NMEA => 1 x NMEA - Multiplexer 4 to 1 For NMEA-networks on yachts,where the data have to be transmittet from various NMEA-receivers (GPS / log / echo sounder / compass ...) one after the other to the  Laptop or in the board network.  A four way NMEA-multiplexer, that transforms 4 NMEA input signals to one NMEA data output. The multiplexer is made for a 12 Volt board network.   Multiplexer 4 to 1   order here

 

SeaTalk <=> NMEA / RS232 converter ST The SeaTalk data are transferred into NMEA datas. So you can connect your Autohelm / Raytheon / Raymaine board network to your Laptop (RS232) or transfer the data to your DSC radio receiver (NMEA). The converter is made for a 12 Volt power supply system. english manual (64kB pdf)   SeaTalk / NMEA   order here
