Page 5: Stu Basic Information
STU BASIC INFORMATION SYSTEM OVERVIEW The Lat-Lon Solar Tracking Unit (STU) is a wireless data system that monitors several parameters on a trailer, railcar, locomotive or any other equipment including GPS data, and sends that data from most any location world wide to Lat-Lon’s database and website. The radio communicates via the GSM digital cellular network. -
Page 6: Hardware
HARDWARE Included Hardware The STU unit (triangular box 9.75” x 7.25” x 4.25”) is a self contained unit that includes everything that is required to track an asset. The unit contains an internal GPS and data communication antenna, a GPS receiver, a data communications radio, a rechargeable hybrid battery, and a processor board. -

2. The power of the unit has dropped below its normal operation threshold Communication requires sufficient proximity to a cell tower for adequate signal strength and the ability of the unit to reach the Lat-Lon web-site (via the internet) for validation that the message was received. - Page 8 The STU can achieve different qualities of location fix. It reports this quality level by reporting how many satellites were used in the solution. The more satellites used, the better the location precision. If six or more satellites are used in the solution, then it will be accurate to 10 meters 95% of the time.

5G 100Hz 5DV (delta velocity) These thresholds can be changed over the air via the Lat-Lon website (see the Website Manual for more information) Below is a chart of a high G force, short interval impact. The force measured at 100Hz was 18.0G’s and the force measured at 10Hz was 1.5G’s. - Page 12 Time (sec) Alarm Event An impact ALARM can be sent to your email address, or text message cell phone (contact your Lat-Lon representative to have this set up). The ALARM event will give you the following information: Time of the event...

Page 13: Stu/I Mounting Instructions
STU/I MOUNTING INSTRUCTIONS Items Provided STU unit (triangular box 9” x 7.25” x 4.25”) Items Needed Lift, ramp or other approved system able to reach mounting location Installation Procedure 5. Remove STU from its delivery box 6. We HIGHLY RECOMMEND putting the STU outside in direct sun as soon as received to allow for solar charging of the batteries (even if you are not installing right away). -

Measures an analog value of the tilt reading and also a digital that the tilt changed by more than X (X is programmed here at Lat-Lon when we make the unit). The tilt also creates a digital value of 1 when it’s at the high-end of its range and 0 when it’s at the low end of its analog range. -

Silicone to back side of the sensor and press on. Then wire tie sensor to keep it in place while silicone dries. Installation for the RF Wireless Sensor depends on the application you will be using it on. (Please call Lat-Lon, LLC at 1-877-300-6566 for additional installation information) -

STU CAMERA INSTALLATION Items Provided STU unit (triangular box 9” x 7.25” x 4.25”) Mounting Options Magnetic Mount Saddle Mount (pictured to right) Bolt-on Mounting Plate Items Needed Lift, ramp or other approved system able to reach mounting location Installation Procedure 9. - Page 18 P. Due to transmission of RF signal we suggest installing the STU with a clear view in front of it. However, we understand this is not always possible therefore, a good rule of thumb would be to have at least 6 feet of clearance in front of the STU in order to avoid reception problems.
