1 INTRODUCTION

1.1 CAUTION

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 16x 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 16x. 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.

1.3 OVERVIEW

The GPS 16x series products are complete GPS sensors including embedded receiver and antenna, designed for a broad spectrum of Original Equipment Manufacture (OEM) system applications. Based on the proven technology found in other Garmin GPS receivers, the GPS 16x tracks multiple satellites at a time while providing fast time-tofirst-fix, one-second navigation updates, and low power consumption. This generation of GPS sensors includes the capability of FAA Wide Area Augmentation System (WAAS) differential GPS.

The GPS 16x design uses the latest technology and high-level circuit integration to ach ieve superior performance while minimizing space and power requirements. All critical components of the system including the RF/IF receiver hardware and the digital baseband are manufactured by Garmin to ensure the quality and capability of the GPS. The hardware capability combined with software intelligence makes the GPS 16x easy to integrate and use.

The GPS 16x series products are designed to withstand rugged operating conditions and are waterproof to IEC 60529 IPX7, immersion in 1 meter of water for 30 minutes. These complete GPS receivers require 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. The system may communicate with the GPS via an asynchronous serial communications port. 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 or RTCM corrections yielding 3- to 5-meter position

accuracy (see section

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

1.5 Technical Specifications).

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

NMEA 0183 Sentences

• Highly accurate one-pulse-per-second (PPS) output for precise timing measurements. Pulse width is

configurable in 20-millisecond increments from 20 ms to 980 ms with 1 μs accuracy.

• Configurable for binary format data output on COM1 port.

• Flexible input voltage levels of 3.3 Vdc to 6.0 Vdc with over-voltage protection in the GPS 16xLVS, and

8.0 Vdc to 40 Vdc in the GPS 16xHVS.

• FLASH-based program with new software revisions available through Web site download.

• Non-volatile memory does not require battery backup.

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

2 GPS 16x WIRING AND PINOUTS

2.1 GPS 16x PINOUT

The GPS 16xLVS and GPS 16xHVS sensors utilize an 8-pin RJ-45 plug. The following is a functional description of each wire in the cable assembly.

RJ-45

Wire

Color

Signal

Name

Description

1 Red POWER GPS 16xLVS: Regulated +3.3 to +6 Vdc. Typical operating current is 80 mA.

An internal 6.67 Vdc transient zener diode and a positive temperature coefficient resistor protect from transients and over-voltages. With voltages greater than 6.8 Vdc the zener will draw several amps of current through the resistor, causing it to heat rapidly and eventually power the unit off, unless an external fuse blows first. When proper supply voltages are returned, the resistor will cool and allow the GPS 16xLVS to operate.

GPS 16xHVS: Vin can be an unregulated 8.0 Vdc to 40 Vdc, optimized for 12 Vdc. Typical operating power is 780 mW. This voltage drives a switching regulator with a nominal 5.0 Vdc output, which powers an internal linear

regulator, producing the system Vcc. 2 Black GROUND Power and Signal Ground 3 Yellow REMOTE

POWER ON/OFF

External Power Control Input. Active (ON) if less than 0.3 Vdc. Inactive (OFF) if

open-circuit. Pulling this pin to ground enables the unit; leaving the pin open-

circuited powers the internal regulators off and drops the supply current to less

than 1 mA. This input is intended to be driven by an open-collector output. 4 Blue PORT 1

DATA IN

First Serial Asynchronous Input. RS-232 compatible with maximum input

voltage range -25 < Vdc < 25. This input may also be directly connected to

standard 3 to 5 Vdc CMOS logic. The low signal voltage requirement is <0.6 V,

and the high signal voltage requirement is >2.4 Vdc. Input impedance is between

3.0 and 7.0 kΩ. This input may be used to receive serial initialization/ section 4.1 Received NMES 0183 Sentences.

5 White PORT 1

DATA OUT

configuration data as specified in First Serial Asynchronous Output. This RS-232 compatible output normally

provides serial data which is formatted per NMEA 0183, Version 3.0. The NMEA 0183 baud rate is switchable in the range of 4800 to 38400 baud. Th e default baud rate is 4800.

6 Gray PPS One-Pulse-Per-Second Output. Typical voltage rise and fall times are 300 ns.

Impedance is 150 Ω. Open circuit output voltage is low = 0 Vdc and high = Vin in the GPS 16xLVS, and low = 0 Vdc and high = 5.0 Vdc in the GPS 16xHVS and GPS 17HVS. The default format is a 100 ms wide active-high pulse at a 1 Hz rate; the pulse width is configurable in 20 ms increments. Rising edge is synchronized to the start of each GPS second. This output provides bet we e n 800 mVp-p to 1.7 Vp-p for GPS 16xLVS and 1.4 Vp -p for the GPS 16xHVS and 17HVS into a 50 Ω load. The pulse time measured at the 50% voltage point will be about 50 ns earlier with a 50 Ω load than with no load.

7 Green PORT 2

DATA IN

Second Serial Asynchronous Input, electrically identical to PORT 1 DATA IN. This input may be used to receive serial differential GPS data formatted per

RTCM SC-104 Recommended Standards For Differential Navstar GPS Service,

section 4.5 Received RTCM Data for details).

8 Violet PORT 2
