Important Information

CAUTION

The SMART DGPS RECEIVER "GSU series" units are believed to be accurate and

reliable, but they can be misinterpreted. For this reason we suggest that you read

carefully this User Manual and make sure you understand with its contents before

using the SMART DGPS RECEIVER "GSU series" units. For a safe navigation compare

information received from GPS to all available navigation indications received

from other electronic navigation navaids that you carry on board.

Do not open the SMART DGPS RECEIVER "GSU series" units. There are not

serviceable parts inside. Repairs should only be made by an authorized electronic

technician, please contact your local dealer (any unauthorized repair could result

in damage to the unit and this damage may not be covered by the warranty).

LIMITED WARRANTY

The manufacturer warrants each SMART DGPS RECEIVER "GSU series" units to be

free from defects in material and workmanship under normal use and service for

a period of 24 months from original retail purchase. During the warranty period,

the manufacturer will repair or replace any component which fails in normal use

without charges for parts or labour.

To receive warranty service, contact your local authorized dealer for shipping

instructions. The SMART DGPS RECEIVER "GSU series" unit should be securely

packed with its tracking code clearly written on the outside of the package, shipping

to be paid by the customer. Include a copy of the original sales receipt as the

proof of purchase. The manufacturer will return the SMART DGPS RECEIVER "GSU

series" unit to the purchaser freight prepaid.

This limited warranty does not extent to any SMART DGPS RECEIVER "GSU series"

unit which has been subjected to misuse, neglect, accident, incorrect wiring or

improper installation. The manufacturer reserves the right to repair or replace the

SMART DGPS RECEIVER "GSU series" unit at its sole discretion.

This warranty is in lieu of all other warranties either expressed or implied.

THIS IS THE ONLY WARRANTY. THE MANUFACTURER EXPRESSLY DISCLAIMS ANY

AND ALL OTHER WARRANTIES INCLUDING WARRANTIES OF SUITABILITY OR

FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT WILL MANUFACTURER BE

YOU SPECIFIC LEGAL RIGHTS WHICH MAY VARY FROM STATE TO STATE.

NOTE We will not be liable for errors contained herein, or for incidental or

consequential damages in connection with the performance or use of this

material.

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.

1.5 MECHANICAL CHARACTERISTICS & MOUNTING

GSU MODEL

1.5.1 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 rotating

on the antenna mounting bracket.

Fig. 1.5.1 - 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 0,31" (8 mm) hole

and three 0,13" (3.2 mm) holes.

1. SMART DGPS RECEIVER

This SMART DGPS RECEIVER is based on a ultimate 16 channels GPS engine that

delivers accuracy better than three meters by decoding the GPS correction sig-

nals 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 perform-

ance in an easy to use package.

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).
