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...
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.

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 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.
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...

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.

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.
”Choosing a mounting location” on page 13. Fabricate the appropriate wiring; for details, see ”Using the 2201-CA cable” on page 17. Connect the 2201 to the desired instrument and to power: For the 2201 binary, see ”Connecting the 2201 2201 INSTALLATION MANUAL, Revision B...
INMARSAT or radar antennas, and away from any other high-power transmitting antennas. • Locate the 2201 where it has an adequate view of the sky. Mount the 2201 high enough to provide an unobstructed view of the sky in all directions, and minimize or eliminate any objects that block the 2201’s view of the sky.
2201 onto a standard antenna mast. Do not overtighten or you may damage the housing! Use a tie-wrap or equivalent near the 2201 to hold the weight of the cable so the connector isn’t stressed by the cable’s weight.
Mounting on a flat surface 1.00-14UNS-2B X 1.00 Page 16 You can mount the 2201 on a deck or any other flat surface. Using the three screws and washers provided, mount the 2201 on the flat surface with three holes on a 1.75-inch diameter circle (see Figure 3 below).
7-pin connector that plugs right into the 2201’s 7-pin connector. The other end has stripped and tinned leads, to be used to either connect the binary 2201 to a Northstar 941/951/952 (the leads are used for the data interface connections to Northstar’s WA215 cable, and to power), or to...
2201 INSTALLATION MANUAL, Revision B SECTION THREE Interfacing the 2201 This section explains how to connect the 2201 (binary) to the Northstar 941, 951, or 952, and connect the 2201 to power. The 2201 is interfaced with the Northstar 941/951/952 by connecting the 2201-CA interface cable to Northstar’s WA215...

2201 INSTALLATION MANUAL, Revision B SECTION THREE Interfacing the 2201 NOTE: If the 2201’s power isn’t turned off by one of these methods, the 2201 will continuously draw up to 0.2 A from the ship’s battery. Using remote power on This option will automatically power-on or power-off the 2201 as soon as the Northstar 941/951/952’s power is turned on or...
2201/NMEA can be turned off when not in use (it will draw up to 0.2 A from a ship’s battery if left on). If the 2201 is connected to its own power source, use a 1-2 amp circuit breaker. The 2201 can also be connected to the same circuit breaker as the 941/951/952, or to another switched source.
