GPS 1500 User Manual PN 2005906 Rev.
OVERVIEW INTRODUCTION The GPS 1500 is a smart antenna that tracks GPS and SBAS (WAAS and EGNOS) signals. CABLE CONNECTIONS DISPLAY GPS OVERVIEW The receiver is preconfigured and will work out of the box for most applications. When powered for the first time, the reciever will perform a “cold start,” which involves acquiring the available GPS satellites in view and the SBAS differential service. GPS OPERATION The GPS engine is always operating, regardless of the DGPS mode of operation.
The receiver uses a complex algorithm incorporating satellite locations and ranges to each satellite to calculate the geographic location. Reception of any four or more of these signals allows a GPS receiver to compute three-dimensional coordinates. DIFFERENTIAL OPERATION The Radio Technical Commission of Marine services (RTCM) has a differential service intended for correction services.
SETUP UTILITY SETUP PROCEDURE The default GPS settings are 4800 baud, 1 Hz GGA and VTG NMEA strings.These settings will work for all Ag Leader products.However, if the equipment that you are using requires higher baud or Hertz rates, you many need to reconfigure the GPS using the following procedure. 1.Download the Pocket Max PC.exe executable file from Ag Leader’sweb site: http://www.agleader.com/support.php?Page=downloads 2.Double click on Pocket Max PC.exe. 3.The Pocket Max PC program appears.
5.Once the utility finds the correct GPS receiver, the OK button appears at the bottom of the window. Press the OK button. 6.When the new window appears, click the Setup tab. 7.Under the “This Port” column, (located on the left-hand side of the window) use the drop-down menu to select the correct Hz rate, such as 5 Hz. Selecting correct Hz rate on a NMEA string Note: Ag Leader’s products require the GGA and VTG NMEA strings.
9.When setup is complete, press on the Exit button, which is the located in the right-hand corner of the window. red X 10. The Exit Options window appears, asking you to choose one of the following options. Always press Exit and Save. Exit Options window Note: If you choose a selection other than Exit and Save, your settings will not be saved. 11.A series of messages appears, after which a Configuration Report will appear. At the configuration report, you can view your saved settings.

CABLE INTERFACE The cable options include: • DB9 serial • Speed • Power Additional extension cables may be purchased, as necessary, for other installations. This allows the reciever to be quickly and easily moved from one installation to another. If an extension cable is damaged in the field, it can be replaced without returning the complete system. EXTENSION POWER/DATA CABLE The system is quickly installed with one of the various extension cables.
Cable Part Numbers Ag Leader® INTEGRA, EDGE, InSight, PF3000, YM2000: 4002673-18 PF Advantage: 4002674-18 Mobile Logging (Laptop and Handheld): 4002675-18 MOUNTING THE GPS 1500 PLACEMENT ON VEHICLE Placement is crucial to the system’s operation. The GPS engine inside the reciever computes a position based upon measurements from each satellite to the internal GPS antenna unit. Mount the reciever on your point of interest.
RADAR SPEED COMPATIBILITY Adaptor cables are available through Ag Leader TechnologyAutoFarm for the following three brands of monitors: Dickey-John, Raven, and Hiniker. These adaptor cables provide the ability to use the GPS 1500 in place of a radar gun. If using the reciever as a stand-alone antenna, you will need to obtain an Auxiliary Power/Data Cable and the appropriate Radar Speed Adaptor Cable.
CONNECTIONS TO EXTERNAL DEVICES The serial ports of the GPS 1500 operate at the RS-232C interface level to communicate with external data loggers, navigation systems and other devices. The serial ports are accessible via the extension cable that features a DB9 female data connector. The serial ports are also used for firmware updates. Note: For successful communication, the baud rate of the GPS 1500 serial ports must be set to match that of the devices to which they are connected.
