Connecting an NMEA Source

• Use the BLUE and BLACK twisted pair for connection to the

NMEA data source.

• Connect the BLUE wire to the NMEA A signal.

• Connect the BLACK wire to the NMEA B signal.

(Trouble shooting: Note that NMEA signal terminology can vary

between manufacturers – try swapping the BLUE and BLACK wires

if the NMEA input does not work initially – no damage will be done)

The Nav6 is compatible with most sources of NMEA 0183 data such

as a GPS receiver or adapter boxes supplied for use with networked

instrument systems. Please note that you may need to program the

source of NMEA data to send the correct sentences in the correct

format. You may also need to purchase an NMEA adapter box for

your instrument system. Should you be uncertain of your abilities in

this area, you are strongly advised to seek the services of a qualified

marine electronics installer.

Note: We do not guarantee compatibility with all GPS receivers or all

instrument systems. However, this can normally be achieved for

most systems by a skilled installer. For notes on achieving

compatibility with various systems, see the Nav6 FAQ section on our

web site: www.icselectronics.co.uk

The Nav6plus uses NMEA data for the following:

• To synchronise its internal clock with UTC time.

• To display a wide variety of NMEA data in a selection of formats

(see Appendix IV for the NMEA sentences supported).

• To automatically filter the message display to show either

messages from only the nearest Navtex transmitting station, or

all stations that are currently within range.

The programming signal (GREEN and BLACK twisted pair) is not

required for normal operation and should be left unconnected.
