QUICK START GPS105-VR1.01
Installation & Quick Start Guide
GPS105 Smart GPS Sensor
1. Introduction
Congratulations on the purchase of your GPS105 Smart GPS Sensor. It is recommended that your receiver is installed by
a professional installer. You will need to purchase a suitable 1” x 14 TPI thread mounting bracket for the GPS105.
Before operating the unit you should also familiarise yourself again with the user manual of the
equipment that you are connecting the GPS105 to. Pay particular attention to the GPS Interfacing section
and any settings that need to be configured for correct operation.
2. Before you start
The GPS105 is a smart “all in one” GPS receiver solution for small boats. Simply connect the GPS105 to a 12v or 24v DC
supply and it will immediately start receiving GPS data and outputting this data in NMEA 0183 format (4,800 baud).
Carefully consider how you wish to connect the GPS105 to your existing navigation system before you start installing
cables. To display the GPS data you will need:
Suitable dedicated chart plotter that can read and display GPS data via NMEA0183
Or a suitable PC Navigation software running on a PC with Microsoft Windows XP®/Windows 2000®or Windows
Vista®/Windows 7®with a free RS232 serial port or a free USB port with a USB to NMEA adaptor.

3. Installation
Before starting installation select a suitable location for the GPS105 Receiver. The unit is water proof and designed for
on-deck mounting. The GPS105 antenna has the popular 1” x 14 TPI thread mount, found in many VHF antennas. A wide
variety of different brackets are available for this type of threaded mount, consult your local marine electronics dealer or
chandlery for more information.
The 1” x 14 TPI thread mount can also be removed, allowing the GPS105 to be flush mounted on a flat horizontal
surface.
The GPS105 is supplied with 7.5m of cable and this should be routed through the vessel to a suitable dry internal location
where it can be connected to the boat’s DC power system and the equipment it will be interfaced with. The cable can be
shortened, lengthened or joined without problems.
The GPS105 should be connected to the boat’s DC supply via a 1 Amp fuse. The unit requires 9.6V to 28.8V supply
voltage.
Below are the wiring details for the GPS105 and a connection diagram that shows how to interface it to other navigational
equipment.

When connecting to a two wire NMEA
Input (such as Raymarine), connect
the GPS105 Green wire to the NMEA
+ Input and the Screen/Shield to the
NMEA –Input.
When connecting to a single wire
NMEA Input (such as Garmin),
connect the GPS105 Green wire to
the NMEA + Input and the
Screen/Shield to the Power –(0v).
