  • Page 4: Overview

    The pigtails connect directly to the control terminals of our data loggers or with the aid of an A300. The GPS16X-HVS includes the GPS receiver and antenna in the same housing with one cable for the power supply and communications. The GPS antenna must have a clear view of the sky.

  • Page 5: Compatible Data Loggers

    Except for the CR9000(X), our data loggers use the CRBasic GPS() instruction to read the GPS16X-HVS. To use the PPS functionality, some data loggers need an updated clock chip. The clock chip is factory replaced (refer to page for more information). Data loggers with the following serial...

  • Page 6: Initial Inspection

    GPS16X-HVS GPS Receiver Initial Inspection Upon receipt of the GPS16X-HVS, inspect the packaging and contents for damage. File damage claims with the shipping company. QuickStart A video that describes data logger programming using Short Cut is available at: www.campbellsci.com/videos/cr1000x-datalogger-getting-started-program- part-3. Short Cut is an easy way to program your data logger to measure the GPS16X-HVS and assign data logger wiring terminals.

    GPS16X-HVS GPS Receiver Select the output options. Click Finish and save the program. Send the program to the data logger if the data logger is connected to the computer. If the sensor is connected to the data logger, check the output of the sensor in the data display in LoggerNet, RTDAQ, PC400, or PC200W to make sure it is making reasonable measurements.

    Use the DB9-Male-to-Terminal-Block interface to connect the GPS16X-HVS to the RS-232 port of the CR9000X CPU card. See TABLE 6-2. To change the default settings, connect the GPS16X-HVS to a computer. Either use the A200 interface to connect to a computer USB port or the...

  • Page 11: Using With An A300

    In 2014, Garmin changed the pulse-per-second (PPS) output of the GPS16X-HVS from 5 V to 3 V. Units with a serial number 1A4189318 or greater have a PPS output of 0 to 3 V. For those units, an A300 is needed to connect the PPS output to a CR800-series, CR3000, or CR1000 data logger.

  • Page 12: Mounting

    5 V Signal Output C (Tx) Mounting The GPS16X-HVS mounts to a mast or crossarm using the CM235 Magnetic Mounting Stand. Typically, the GPS16X-HVS mounts to the CM235 magnetically with the Magnetic Mount. Alternatively, the GPS16X-HVS can be mounted directly to the CM235 using three M4 screws supplied with the 17212 or by the customer.

    Flow control should be none. Using the DB9-Female-to-Terminal- Block interface, connect the GPS16X-HVS to the computer serial port. Power up the GPS16X-HVS. The GPS antenna should have a clear view of the sky. Don’t expect the GPS antenna to work indoors. The $GPGGA and GPRMC strings should be displayed once a second.

  • Page 19: Nmeastrings Variable Populated, But Clock Not Setting

    GPS16X-HVS GPS Receiver likely need to go outside to obtain a better signal. If you see “garbage” characters coming in (that is, non-NMEA strings), there is likely a baud rate mismatch. NMEAStrings Variable Populated, but Clock Not Setting Look at the GPSReady variable. It will increment from 0 to 10 when the data logger has received good GPRMC strings and a synchronized PPS signal.

  • Page 20: Changing Gps16X-Hvs Settings

    A.1 Computer Connections Either an A200 interface or a DB9-Female-to-Terminal-Block interface is required to connect the GPS16X-HVS to a computer. The A200 is used to connect to a computer USB port, and the DB9 Female to Terminal Block is used to connect to a computer 9-pin serial port.

  • Page 21: Wiring

    One end of the A200 has a terminal block while the other end has a type B female USB port. The terminal block provides 12V, G, TX, and RX terminals for connecting the GPS16X-HVS (see FIGURE and TABLE A-1). A data cable ships with the A200. This cable has a USB type-A male connector that attaches to a computer USB port, and a type B male connector that attaches to the A200 USB port.

  • Page 22: Powering The Sensor

    Appendix A. Changing GPS16X-HVS Settings A.1.1.3 Powering the Sensor The A200 provides power to the GPS16X-HVS when it is connected to a computer USB port. An internal DC/DC converter boosts the 5 VDC supply from the USB connection to a 12 VDC output that is required to power the sensor.
