1 INTRODUCTION

1.1 CAUTIONS

CAUTION

The GPS system is operated by the government of the United States, which is solely responsible for its accuracy and
maintenance. Although the GPS 17x HVS is a precision electronic NAVigation AID (NAVAID), any NAVAID can
be misused or misinterpreted, and therefore become unsafe. Use these products at your own risk. To reduce the risk,
carefully review and understand all aspects of these Technical Specifications before using the GPS 17x HVS. When
in actual use, carefully compare indications from the GPS to all available navigation sources including the
information from other NAVAIDs, visual sightings, charts, etc. For safety, always resolve any discrepancies before
continuing navigation.

FCC

Compliance

This product has been tested and found to comply with Part 15 of the FCC interference limits for Class B digital
devices FOR HOME OR OFFICE USE. These limits are designed to pr ovi de m ore reas onable protection against
harmful interference in a residential installation, and are more stringent than “outdoor” requirements.

Operation of this device is subject to the following conditions: (1) this device may not cause harmful interference,
and (2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio
communications if not installed and used in accordance with the instructions. However, there is no guarantee that

1.3 OVERVIEW

The GPS 17x HVS is an embedded receiver and an antenna. Based on the proven technology found in other Garmin
GPS receivers, the GPS 17x HVS tracks multiple satellites at a time while providing fast time-to-first-fix, precise
navigation updates once per second, and low power consumption. This generation of GPS sensors includes the
capability of FAA Wide Area Augmentation System (WAAS) differential GPS.

The GPS 17x HVS design uses the latest technology and high-level circuit integration to achieve superior
performance while minimizing space and power requirements. The hardware capability combined with software
intelligence makes the GPS 17x HVS easy to integrate and use.

The GPS 17x HVS is designed to withstand rugged operating conditions and is waterproof to IEC 60529 IPX7:
immersion in 1 meter of water for 30 minutes. The complete GPS receiver requires minimal additional components
to be supplied by an OEM or system integrator. A minimum system must provide the GPS with a source of power
and a clear view of the GPS satellites. Internal FLASH memory allows the GPS to retain critical data such as
satellite orbital parameters, last-known position, date and time. End user interfaces such as keyboards and displays
are the responsibility of the application designer.

1.4 FEATURES

• GPS receiver tracks and uses multiple satellites for fast, accurate positioning and velocity estimates.

• Differential DGPS capability using real-time WAAS corrections yielding positio n errors of less than 3

meters.

• Compact, rugged design ideal for applications with minimal space.

• Factory configuration meets the needs of most systems that expect NMEA 0183 data from a GPS receiver.

Configuration commands are available to customize the NMEA 0183 output (see

NMEA 0183 Sentences

)

section 4.1 Received

• Highly accurate measurement pulse output for precise timing measurements: one-pulse-per-second (1 Hz).

Pulse width is configurable in 20 millisecond increments from 20 ms to 980 ms with 1 μs accuracy.

• Configurable for binary format data output.

• FLASH-based program allows new software revisions through a Web site download.

• Non-volatile memory does not require battery backup.

• Onboard rechargeable backup battery can maintain the real-time clock for up to 10 days.

• Configurable parameters include expected position, current time and date, and preferred position fix type

(3D or automatic).

• Waterproof design allows continuous exposure to the prevailing weather conditions at most locations.

1.5 GPS 17X SERIES

1.5.1 GPS 17x HVS

The GPS 17x HVS interfaces to a RS-232 serial port of a
computer via a DB-9 connector and receives power through a
vehicle power adapter. The GPS 17x is RS-422 compatible.
See the

wiring diagrams for correct wiring.

The GPS 17x HVS can cause an issue with Microsoft®
Windows

Exceptions:

If your NMEA 0183-compliant device has only one receiving wire (Rx), connect it to the gray wire (Tx/A) from the
GPS 17x antenna, and leave the white/red wire (Tx/B) from the antenna unconnected.

If your NMEA 0183-compliant device has only one transmitting wire (Tx), connect it to the white wire (Rx/A) from
the GPS 17x antenna, and connect the white/orange wire (Rx/B) to ground.

Note: The orange (accessory on) wire is used when wiring the GPS 17x to a Garmin chartplotter, or other NMEA
0183 device that has a defined accessory signal wire. If you are wiring the GPS 17x to a device that does not have an
accessory signal wire, the orange wire from the GPS 17x should be connected to ground.

Caution: If you are wiring the GPS 17x to a device that does not have an accessory signal wire, connect the
GPS 17x power wire to the ignition or install an in-line switch. The GPS 17x can drain the battery of the boat if it is
not switched.
