These installation instructions are the result of tests
performed in our laboratory and we believe these tests
to be accurate and complete. However, each
installation involves variables that cannot be controlled
or predicted. These variables may affect the
operational characteristics of the system.
To ensure proper system operation, 3M strongly
recommends that, when the system is turned on, the
installer functionally tests the system using the following
procedure.
1. Place the Opticom GPS-equipped vehicle in an area
with GPS coverage. This is either outdoors, away
from nearby buildings and overhanging trees, or
inside of a garage equipped with a GPS re-radiator.
2. Verify that the vehicle equipment acquires GPS.
Turn the vehicle control unit on by pressing the
ON/OFF switch. The unit should acquire GPS
within a few minutes; however, it may take up to 15
minutes. A green GPS indicator means that GPS
has been acquired. An amber GPS indicator means
that GPS has not been acquired. If GPS has not
been acquired within 15 minutes, turn the control
unit off and wait another 15 minutes. Then turn it
back on. If the unit still has not acquired GPS,
verify that your location has a good view of the sky
or a working re-radiator. If you are unable to
acquire GPS, contact 3M Technical Service or your
dealer.
3. Verify that the vehicle radio/GPS unit is
transmitting information properly. The vehicle
radio/GPS unit will not operate if the system has
not acquired GPS. Therefore, this check cannot
be completed unless you have GPS.
Place the vehicle to be tested in close proximity of
another known good Opticom GPS-equipped
vehicle or intersection. This vehicle or intersection
also must have good GPS coverage.
Vehicle Equipment Installation Instructions
If a vehicle is used, its radio must be placed in
Transmit mode because vehicle radios will not
transmit unless they hear an intersection radio.
Open the View Inputs Sensing window and select
the Transmit Test tab. Press the Test Mode button.
The vehicle radio will now transmit even if it does
not hear an intersection radio. The vehicle radio will
stay in this mode until the next power cycle.
NOTE: If an intersection is used for this test,
activate the vehicle's disable switch or you will
be placing priority requests to the intersection
controller. Therefore, it is recommended that
another Opticom GPS-equipped vehicle be
used for testing.
Open the Vehicles & Intersections Heard window
under the Real Time Activity section in ITS
Explorer. This window is duplicated in both the
Vehicle and Intersection modules of ITS Explorer.
Verify that you are receiving the correct following
parameters from the vehicle under test.
?? Agency ID
?? Class ID
?? Vehicle ID
?? Priority
You should also receive the following information
from the vehicle under test. You will not be able to
verify the values, but you need to verify that the
information is being transmitted.
?? Latitude and Longitude
?? Heading and Velocity
?? Fix Type
?? Position Dilution
?? Horizontal Dilution
?? Satellites
Activate the left turn signal, the right turn signal, the
disable switch and verify that the correct
information is being transmitted. This verifies that
the vehicle under test is set up correctly and is
transmitting all required information.
4. Verify that the vehicle radio/GPS unit is receiving
information properly.
Connect the computer running ITS Explorer to the
vehicle under test and repeat the above procedure
looking for the data being transmitted from your
known good vehicle or intersection equipment.
This verifies that the vehicle under test is receiving
all required information.
