Raynav 300 GPS Plotter

Connect the power supply using the standard power cable supplied:

1.Connect the moulded power plug to the PWR/NMEA connector on the rear of the Plotter. Run the free end back to the vessel’s distribu- tion panel or, if insufficient cable length, to a junction box.

2.Cut the cable to length and connect the red wire, via a fuse, to the +ve battery terminal and the black wire to 0V (-ve battery terminal). Pro- tect the circuit with a 1A quick blow fuse or circuit breaker.

3.Use a suitable junction box to connect to NMEA equipment if required.

4.Cut any unused cores short or insulate and tape back.

Note: If the power connections are accidentally reversed, the system will not function. Use a voltmeter to check that the input power leads are the correct polarity.

SeaTalk Connector

The Plotter can be connected to an existing SeaTalk system by connecting a SeaTalk cable (available from your Raymarine dealer) into the SeaTalk connector on the rear of the Plotter. The data is passed from instrument to instrument via the daisy chained cable.

Note: The SeaTalk connector cannot be used to power the Plotter. Power is not supplied to other SeaTalk equipment.

5.7 System Check and Initial Switch On

When you have installed your Plotter and made all the connections, you need to check your installation before using the system for navigation. If you encounter any problems, refer to Chapter 6: Maintenance & Fault Finding.

EMC Conformance

Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting etc.

System Check

Before performing the functional test, check that:

All connections have been made.

All connecting wires are secured and protected.
