Step 3
Adjust horizontal arms to position sensor
platform to near level. Exact position is not
critical. Tighten horizontal arms and hitch
support screws to stabilize entire structure.
Connect fiber optic cables through one of
the upper bed mounts noting color coding
for polarity. Supplied fiber optic cable needs
to be connected to the laptop inside of the
vehicle. It is recommended that the cables
be inserted through a customer drilled hole
and used with a grommet to not damage
the cable, but you can temporarily insert
through windows or door frame, insuring
that cable is not crimped.
Step 4
Inserting Sensor. After charging sensor, insert the sensor into the
weatherproof enclosure. Fiber optic connection is to be orientated towards the
front of the vehicle. Sensor is placed between foam on the top, bottom and
sides of enclosure. Note polarity of cable connection to sensor. Depress
ON/OFF button and verify that light shows green LED. This means sensor is
ready for measurements.
Step 5
Connecting computer. The fiber optic cable that was connected on one end to
the upper bed mount needs to be connected to the laptop computer in the
cab of the vehicle. Although you can route the cable through a window or
door jamb for a short period of time it is highly recommended that a
permanent hole be drilled into the cab (with grommet) of the vehicle so that
the fiber optic cable is not damaged. The cable is marked with a white dot for
what should be on top when the
connection is made to the RS-232 adapter.
The cable is connected to the F.O. to RS-
232 adapter (supplied) and then to the
computers’ COM1 port. With the computer
charged or powered by an inverter in the
vehicle, and with the sensor fully charged –
you are now ready to energize the system
and verify performance.
