Tilt
Displays the current tilt angle in degrees. Once the tilt sensor has been zeroed out
on level ground, the tilt reading should be 0°.
Temp
Displays the current temperature of the tilt sensor.
Dir
Displays the current direction of motion of the machine. The two possible directions
are F (forward) and R (reverse).
Antenna Height
Tilt compensation is required if the GPS antenna is located above ground level. The
antenna height is used by the tilt sensor to compensate for tilt in the machine. Every
foot of antenna height adds about 1 inch of error with a tilt angle of 5 degrees. For
normal operation, entering a height to the nearest half-foot is adequate.
GPS Delay
There is a slight delay from the time a GPS receiver requires to calculate a position
solution until the time that the solution is transmitted over a serial connection. In
order to synchronize TM1 sensor information with this position message, a time
delay must be entered. For most receivers running at 10 Hz, the default delay of 65
ms is adequate.
Reverse Polarity
The tilt sensor provides the option of an external switch that can be tied to a reverse
switch or light. The polarity of this signal can be either positive or negative. If no
external switch is provided, set the reverse polarity to high.
Tilt Filter
The tilt filter provides varying levels of averaging of the tilt signal. When the tilt filter
is off, the tilt sensor is bypassed and no correction is performed to the GPS data.
When the filter is set too fast, the tilt signal is not averaged. This setting may be used
on relatively smooth ground. If the ground is rough, either the slow or norm settings
should be used. This setting will supply some smoothing of the tilt signal to compen-
sate for rough ground conditions.
