Chapter 12 - Setting Up Your 958

Changing your port settings

You can interface the 958 directly to a variety of external equipment, such as the Northstar 490 “black box” for fishfinding, autopilots, depth sounders, PC’s, and so on. The

958’s ports meet the specifications of most navigation devices, providing you with a customized setup for practically any

NMEA 0183-compatible equipment.

The 958 is interfaced with other equipment through its data transmission ports: two NMEA ports (NMEA) and one auxiliary port (AUX). To see the wiring information, press the STAR key to display the OPTIONS/SERVICE INFO screen, then the PORT

SETUP OPTIONS key, then the WIRING INFO key.

For details about interfacing the 958, contact your local authorized Northstar dealer.
