• Current Direction Indicator - Indicates the direction in which the machine is traveling. Verify that the direction
of travel is displayed correctly when the machine is being driven in both forward and reverse.
• 3D Compensation - Check the 3D Compensation box to toggle the 3D compensation features on or off. When
disabled, the SmarTrax system will not adjust the displayed guidance path for any machine tilt during field
operations.
• Calibrate - Used to calibrate the 3D terrain compensation feature. Refer to the 3D Compensation Calibration
section on page 23 for the calibration procedure.

• HDOP Limit - Horizontal Dilution of Precision (HDOP) is an indicator of the quality of the GPS signal. A high
HDOP indicates that not enough satellites are distributed evenly throughout the sky, diminishing the accuracy
of the guidance system. The number displayed is the maximum number SmarTrax will allow to run. Raising this
number may degrade system performance.
NOTE: The default SmarTrax HDOP limit is 2.5. Increasing the HDOP limit may degrade SmarTrax
performance. Decreasing the HDOP limit may cause SmarTrax to disengage more often.
• Baud Rate - The rate the system uses to communicate with the GPS receiver. This value is typically set to 19200
or 115200, but it can be changed to match the baud rate of receivers that cannot be easily changed.
• Min GPS Correction - This setting is used to select the correction source providing the minimum accuracy
allowable for SmarTrax operation. This selection may be used to prevent the SmarTrax system from sudden
course changes if the desired correction source is lost. For example, selecting RTK for this feature will
disengage SmarTrax if RTK corrections are lost.
• GPS Frequency - The GGA message update frequency in Hertz (Hz).
