•
If no obvious method of connection to the SeaTalk network exists at the location you want to mount the ST-NMEA
converter, then it is possible to cut in to a SeaTalk cable and create/splice in your own connection point.
It is very
important
that if you decide to do this, that you remove all 12v power from the SeaTalk network before cutting in
to the SeaTalk cable.
•
The three wires in a typical Raymarine/Autohelm SeaTalk network cable are;
o
RED
=
12v Supply (+)
o
YELLOW
=
Data
o
SHIELD
=
0v Supply (-)
•
There are two cables on the Digital Yacht ST-NMEA ISO converter and the SeaTalk cable is the left hand, three
core cable. This cable does not have a shield and the negative supply voltage wire is the Black one. After cutting
in to an existing SeaTalk cable connect three wires of the ST-
NMEA Converter’s SeaTalk cable, so that the three
RED wires are together, the three YELLOW wires are together and the Converters’s BLACK wire plus the two
SHIELDs are together.

USB Connection
The ST-NMEA Converter (USB) has an integral 1m USB cable allowing it to be easily plugged in to any computer with a
spare USB type A socket. Before connecting the ST-NMEA Converter to the PC, it is necessary to install the USB drivers.
The exact procedure varies between the different types of Operating Systems that exist for PCs, but the following section
details the procedure for the popular operating systems;

On the
Digital Yacht Software and Drivers CD
, there is a folder called “USB Drivers for AIS units” which contains the
drivers required for the ST-
