Garmin GPS 17x Installation Manual

The Garmin GPS 17x is a high-performance, waterproof NMEA 2000 and NMEA 0183 compatible GPS sensor designed for marine applications. It provides precise position, speed, and heading data to compatible chartplotters and marine networks. Below are key sections for safety, features, installation, configuration, operation, and troubleshooting.

Features at a Glance

Key components: GPS 17x sensor, Mounting hardware, Power/NMEA 2000 cable, Documentation.

Installation Overview

Unpack and inspect contents. Plan installation location for clear sky view.

1. Select Location: Choose a location with unobstructed view of the sky, away from tall obstructions, radar, and communication antennas.
2. Prepare Mounting Surface: Ensure surface is flat, clean, and strong enough to support the unit.
3. Route Cables: Plan cable routes to avoid sharp bends, heat sources, and moving parts.
4. Connect to Power & Network: Follow wiring diagrams for NMEA 2000 or NMEA 0183 connections.

WARNING! Disconnect all power before making electrical connections. Ensure mounting surface is structurally sound.

Mounting the GPS 17x

Secure the sensor using provided hardware.

1. Flush Mount:
   • Place mounting template on surface.
   • Drill four mounting holes and one center cable access hole.
   • Apply sealant around cable access hole.
   • Insert cable through hole, align sensor, and secure with screws.
2. Pole Mount (optional):
   • Attach pole mount bracket to sensor.
   • Secure bracket to a 1" to 2" diameter pole using U-bolts.
   • Ensure sensor face is oriented skyward.

CAUTION! Do not overtighten mounting screws. Use appropriate sealant for marine environments to prevent water intrusion.

Electrical Connections

Connect power and data cables according to your network type.

• Power (Red Wire): Connect to positive DC source (9-40 VDC).
• Ground (Black Wire): Connect to negative DC ground or boat ground.
• NMEA 2000: Connect Blue (Shield) to ground, Bare (Drain) to ground, and use included T-connector to integrate into NMEA 2000 backbone.
• NMEA 0183: Use Yellow (Tx/A Out+) and Green (Tx/B Out-) wires to connect to receiving device's NMEA 0183 input.

Tip: Install an in-line fuse (3A recommended) on the positive power wire near the power source.

NMEA 2000 Network Integration

Integrate the GPS 17x into an existing NMEA 2000 network.

1. Ensure network power is OFF.
2. Connect the GPS 17x cable to a spare port on the NMEA 2000 backbone using a T-connector.
3. Connect the Blue (Shield) and Bare (Drain) wires to the boat's ground.
4. Apply power to the NMEA 2000 network.
5. The GPS 17x should be automatically recognized by compatible chartplotters on the network.

Note: The GPS 17x draws power from the NMEA 2000 network. Ensure the network power supply is adequate.

NMEA 0183 Wiring

Connect to a device using NMEA 0183 protocol.

1. Identify the NMEA 0183 input ports (typically labeled Rx+, Rx-, or NMEA In+, In-) on your chartplotter or instrument.
2. Connect the GPS 17x Yellow wire (Tx/A Out+) to the receiving device's Rx+ or In+ terminal.
3. Connect the GPS 17x Green wire (Tx/B Out-) to the receiving device's Rx- or In- terminal.
4. Connect power and ground wires as described in Section 5.
5. Configure the receiving device to listen to the correct NMEA 0183 sentences (e.g., GGA, RMC).

WARNING! Do not connect NMEA 0183 outputs directly to each other. Connect only to inputs.

Configuration & Setup

Minimal configuration is required. Primary setup is done on the connected display.

1. Power On: Apply power. The LED will flash red while acquiring satellites, then turn solid green with a valid fix.
2. Chartplotter Setup: On your Garmin chartplotter, go to Settings > Communications > NMEA 2000 Setup or NMEA 0183 Setup.
   • For NMEA 2000: The device should appear in the device list. Ensure it is enabled as a position source.
   • For NMEA 0183: Set the serial port connected to the GPS 17x to "NMEA In/NMEA Out" or "NMEA 0183" and the correct baud rate (default 4800 bps).
3. Verify Data: Check the chartplotter's position display or data fields to confirm GPS data is being received.

Operation & Diagnostics

Monitor the LED for operational status.

Data Output: The sensor continuously outputs standard NMEA sentences when powered and has a fix. No user operation is required beyond initial setup.

Maintenance & Care

Periodically inspect the unit and connections.

• Visual Inspection: Check for physical damage, corrosion, or loose cables.
• Connection Check: Ensure all electrical connections are clean, tight, and free of corrosion.
• Cleaning: Wipe exterior with a soft, damp cloth. Do not use harsh chemicals or abrasives.
• Antenna View: Keep the installation location clear of new obstructions (e.g., added equipment, canvas).

CAUTION! Do not disassemble the unit. There are no user-serviceable parts inside.
