This section describes how to configure the SeaTRAX in your host system. To install the
SeaTRAX into your system, follow these steps:
Make electrical connections to the SeaTRAX.
Evaluate the SeaTRAX using SeaTRAX Studio or a binary terminal emulation program,
such as RealTerm or Tera Term, to ensure the heading sensor generally works correctly.
Choose a mounting location.
Mechanically mount the SeaTRAX in the host system.
Perform a user calibration.
4.1 Electrical Connections
The SeaTRAX incorporates a 4 pin Molex connector, part number 53780-0470, which mates
with Molex part 51146-0400 or equivalent, and alternatively allows the user to directly solder
to the board using the 4 through-holes directly in front of the connector. The pin-out is given
below in Table 4-1.

After making the electrical connections, it is a good idea to perform some simple tests to
ensure the SeaTRAX is working as expected. See Section 6 for how to operate the
SeaTRAX with SeaTRAX Studio, or Section 7 for how to operate the SeaTRAX using the
PNI binary protocol.
4.2 Installation Location
The SeaTRAX’s wide dynamic range and sophisticated calibration algorithms allow it to
operate in many environments. For optimal performance however, you should mount the
SeaTRAX with the following considerations in mind:
