Tilt Sensor Operation
The SmartPad II must be loaded with Fieldware software, version 4.03 or higher to be compatible with
the Tilt Sensor. When operating the Tilt Sensor the position data coming from the GPS receiver will be
compensated for vehicle tilt errors and then corrected information will be sent to the console.
When the vehicle experiences a sideways tilt, any guidance information is affected: For example, if the
GPS sensor is 12 feet (3.65m) above the ground, a 10-degree tilt gives a 2-foot (0.61m) positioning
error.
Tilt Sensor Functions
There are three LEDs visible on the Tilt Sensor which indicate the following:
• Blue - Blinks two times per second when the unit is powered and
running
• Green - Steady ON when tilt correction is enabled, OFF otherwise
• Yellow - Blinks one time per second when valid GPS location data
is being received (NMEA-0183 GGA)
Tilt Sensor Mounting Recommendations
1. Mount as close to the center of the vehicle side to side as possible.
2. Mount sensor on a parallel plain to the GPS antenna so both the antenna and the
sensor tilt the same degree.
3. Mount so the sensor is level and connector is pointing upward.
4. Sensor should be rigidly mounted to minimize vibration, because vibration will degrade
the ability to sense tilt.
5. Mid-Tech recommends using nuts and bolts or self tapping screws through the two
mounting holes on each end of the sensor.
6. The arrow on sensor decal must point toward the front of the vehicle.
7. Do NOT mount near extreme temperatures, upside down, or on its side.
