Page 9: Section One Introduction
This section explains who should read this manual, how to obtain technical support, and how to return a 2201 or 2201/ NMEA for servicing. Also described are some of the standard features of the 2201 and 2201/NMEA, and all of their operating modes. - Page 10 2201 (binary output) — for interfacing with new and existing Northstar 941X/XD, 951X/XD, and 952X/XD units in order to provide WAAS differential corrections. (In the future, the 2201 will be able to interface with Northstar’s 961X/XD and 962X/XD.) • 2201/NMEA (NMEA) — for interfacing directly with...

Page 11: Who Should Read This Manual
U.S. mail, or phone as described in the table below. You can also visit Northstar’s website for additional service-related information. Please have the 2201’s serial number available and be as complete and accurate as possible when describing the problem. This ensures that a Northstar service technician can research the issue and provide the quickest possible response. -

Page 13: Servicing The 2201
For units still under warranty, field repairs are not authorized and will void the warranty! For a 2201 under warranty, shipping charges to the factory are the only cost for factory repair. The repaired 2201 will be returned via prepaid economy ground freight (freight for units returned overseas is chargeable). -
Page 14: Returning A 2201 For Service
Page 6 The 2201 is covered by a two-year, hardware-only warranty. In summary, this states that if the 2201 is returned to the Northstar factory by the owner or dealer during the warranty period, Northstar will repair or replace, free of charge, any part found to be defective due to faulty materials or workmanship if the system has been properly installed and hasn’t been abused. -
Page 15: 2201 Operating Modes
The seven operating modes are described in detail below. The 2201 enters self-test mode upon a host’s request, using an NMEA or binary message, via the GPS primary port. This test requires no more than 15 seconds. When the self-test is... - Page 16 After each satellite in view is acquired, the 2201 collects new ephemeris data by decoding the satellite downlink data message. When a sufficient number of satellites are being tracked, position, velocity and time are computed, and the 2201 enters navigation mode.
- Page 17 3-D mode can’t be used. 3-D Nav mode The 2201 operates in 3-D nav mode when it receives data from at least four satellites with adequate geometry, but no differential corrections. This is the preferred navigation mode when sufficient WAAS or external radiobeacon differential corrections aren’t available.

Unauthorized tampering with the unit will automatically void the warranty. As shipped, the 2201 is ready to install and operate. The 2201 is fully automatic; during normal operation, you won’t need to see it, touch it, or send commands to it: Check the shipping carton for any damage, and immediately report any damage to the carrier. -
