SECTION ONE - Introduction
Welcome
T
he Northstar 951/952 Installation Manual describes how to install,
interface, and troubleshoot the Northstar 951 and 952 GPS chart naviga-
tors. Also described are the physical, mechanical, and electrical character-
istics of each unit.
For complete details about operating the unit, see the Northstar 951/952
Operator’s Manual (part number GM1500C).
The terms “unit” and “951/952” are used throughout this manual to refer
to both the 951 and 952 GPS chart navigators. The 952 features a color
display, but is otherwise identical to the 951, except where noted. The
951X and 952X are both differential-ready so you can interface them to
an external differential receiver. The 951XD and 952XD have built-in dif-
ferential receivers. Unless specifically indicated, all information in this
manual refers to both the
X (non-differential) and XD (differential) ver-
sions of the unit.
