Operation GPS 2000/2100
Ag Leader Technology
April 1998 3-2
Power Switch The unit is turned on and off with the rocker switch in the upper right corner
of the keypad (POWER).
Note: Always turn the GPS 2000/2100 unit off when you leave it in the cab
because the unit draws power from the Yield Monitor 2000, even when the
yield monitor is off. If the GPS 2000/2100 is left on, the unit could run
down the vehicle battery.
Serial Ports
The unit has three 9-pin serial ports.
•
The right port, labeled POWER, provides power to the unit and access
to a secondary differential system.
•
The middle port, labeled GPS, sends NMEA messages to the Yield
Monitor 2000 or to an external data logger.
•
The left port, labeled PC, provides access to the unit for updating,
troubleshooting, and data logging.
Antenna The antenna is a combined antenna, housing the GPS and DGPS antennas.
A magnetic base attached to the bottom of the antenna housing provides
easy mounting on metal surfaces. The magnetic base also breaks away if
any object strikes the antenna. The antenna is mounted to a combine with
the provided L-bracket (shown in the photo above).
