Smart DGPS WAAS Receiver
This Smart DGPS WAAS receiver is based on a ultimate 16 channels GPS
engine that delivers accuracy better than three meters by decoding the GPS correction signals from the satellite-based WAAS (Wide Area Augmentation System). The
GPS engine, interface electronics and the passive antenna are enclosed inside the
water-proof plastic housing. This provides advanced state of the art GPS performance in an easy to use package.

WARNING !!!
Cross check the connection on the User Manual of the device connected to the GPS.
1.3 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 MECHANICAL CHARACTERISTICS & MOUNTING
GPU WITH CONNECTOR MODEL
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
inch, 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 rotating 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 0,95 inch (24 mm) hole and
three 0,155 inch (4 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.
