SOFTWARE INTERFACE
The GPS products interface protocol design is based on the National Marine
Electronics Association's NMEA 0183 ASCII interface specification. These standards
are defined in "NMEA 0183 Version 2.0" (for more information see NMEA,
www.nmea.org).

1.4.1 Installing
Choose a location for the antenna that has a clear view of the sky. Ensure there
are no major obstructions or fixtures in the immediate proximity to the antenna.
The antenna relies on direct “line of sight” satellite reception. If you are unsure
that the chosen location is suitable it may be advisable to mount the antenna in a
temporary manner to verify correct operation. The thread used on the antenna
(1", 14 TPI) is an industry standard thread used on a wide range of mounting
brackets, including the swivel joints commonly used for angled surfaces. However
due to the manufacturing process of these mounting brackets you may see that
there is some slop when tightening down the antenna to the bracket. This is of no
concern however as the antenna must be tightened until the antenna stops rotat-
ing on the antenna mounting bracket.
Fig. 1.4.1 - Installing GPS Antenna (I)
The antenna design also allows for easy flush mounting.
1. Apply the adhesive mounting template sheet in the area that was
verified to receive satellite signal well.
2. Then, following template instruction, drill a 1" (25 mm) hole and
three 0,13" (3.2 mm) holes.

3. Remove the template and let the cable go through the central
hole.
4. Apply a small coat of RTV to the underside of the antenna.
5. Place the antenna and then screw it with the three M3 screws.
