DC3 Video Event Recorder
with Safety Enhancement Mode Installation Instructions
Installation of the event recorder is not complicated, but care must be taken to ensure successful
operation. Follow these instructions carefully to ensure proper orientation and operation.
1. Check the contents
of the installation kits

DRC 242-A 2007-08-03 Page 2 DC3 with SEM Installation Instructions
2. Thoroughly clean and dry the glass
CAUTION: This step is critical to prevent the bracket from falling off at a later date.
Step 1 Select a mounting location on the windshield behind the rear view mirror
on the passenger side of the vehicle.
Step 2 Using the alcohol prep pad provided, thoroughly clean the mounting area.
Step 3 Using a clean, dry cloth, thoroughly dry the mounting area.

3. Carefully select the mounting location
The event recorder needs to be mounted in a location that provides an unobstructed view of the interior
and exterior (front) of the vehicle.
CAUTION: Do not peel the backing from the adhesive strip until instructed to do so.
Step 1 Loosen the Torx screws so the event recorder can rotate in the bracket.
Step 2 Pull the mirror down to its lowest position.
Most rear view mirrors can be adjusted up or down. Before selecting the mounting location,
adjust the mirror all the way down so that it can never cover the lens after mounting.
Step 3 Position the assembly behind the mirror, about one inch to the right of the post to allow
easy access to the Torx screw and power connection.

4. Mark the selected mounting location on the glass
Step 1 When you have selected the best mounting location, hold the assembly in place and trace
the outline of the bracket on the windshield with a felt tip marker.
Step 2 Make sure the traced guide marks are level before proceeding.
Step 3 Remove the event recorder from the mounting bracket.
Step 4 Check the fit of the bracket against the windshield.
If the windshield is curved, gently bend the bracket so that it will lie flush against the glass.

5. Attach the mounting bracket to the windshield
CAUTION: The adhesive is very sticky. Once applied to the windshield, it will not easily
come off. See page 25 for bracket removal instructions.
Step 1 Make sure the glass is clean and dry and the air temperature is at least 50°F (10°C).
Step 2 Remove the backing from the adhesive side of the bracket.
Step 3 Start by placing only the top edge of the bracket against the windshield,
aligned with the guide marks, and make sure it is level.
Step 4 Press the bracket firmly against the windshield starting at the top
and pressing the sides downward.
Do not apply excessive pressure as it may cause the windshield to break.
Step 5 Make sure there are no large air bubbles under the bracket.
You may need to (carefully) apply additional pressure to the bracket and remove any large air
bubbles. Use a small pin to create an escape path for the air if the problem is persistent.

6. Route the RJ45 Interconnect Cable
CAUTION: When installing the RJ45 Interconnect Cable in a vehicle with side or curtain airbags,
be certain that neither the cable, nor your installation activities, interferes with any
airbag related mechanisms or otherwise affects airbag deployment.
NOTE: If you plan to connect the primary trigger input to the dome light (page 11), you
may want to route the white wire from the UM05 Switch Cable along side the RJ45
Interconnect Cable at this time.
Step 1 Starting just above the rear view mirror, route the cable under the window trim or
headliner across to the door pillar.
Step 2 Route the cable down the door pillar underneath the vertical door / window trim.
Step 3 Route the cable out from underneath the trim and under the dashboard.
You may need to remove the trim to route the cable. When reinstalling, be careful not to damage
the trim clips or the cable. Keep the cable clear from sharp edges and moving parts.

7. Mount the event recorder in the bracket
Step 1 Plug the RJ45 Interconnect Cable into the event recorder.
Step 2 Place the event recorder in the bracket.
Step 3 Adjust the event recorder so that it hangs vertically (plumb).
Step 4 Secure the event recorder in the bracket using the 2 Torx screws and Torx wrench.
The Large Plastic Washer on the left side of the bracket is designed to partially cover the RJ45
Interconnect cable so that it cannot be unplugged by the driver. The plastic washers can be easily
removed from the metal bracket after removing the screws. Make sure the larger of the two washers is
on the left (power connection) side of the bracket.

8. Wiring Diagram (DC3 with SEM Installation)
The RJ45 Interconnect Cable is 14 feet long with RJ45 (large) connectors at each end. One end of
the cable plugs into the event recorder. It is then routed to a secure location under the dashboard and
plugged into the middle port of the Cable Access Terminal (CAT).
The UM05 Interconnect Cable is 18 inches long with RJ11 (small) connectors at each end. One end of
the cable plugs into the left port of the CAT. The other end plugs into the Universal Module (UM05).
The Power I/O Cable is 30 inches long. One end of the cable plugs into the right port of the CAT. At
the other end of the cable is a brown wire which connects to an ignition-switched power source.
The UM05 Switch Cable varies in length. One end of the cable plugs into the UM05. At the other end of
the cable are six wires which connect to vehicle power, ground, inputs and output (optional).

9. Plug the cables into the CAT and UM05
The best place to keep the Cable Access Terminal (CAT) and the Universal Module (UM05) is usually
under the dashboard. Find a suitable location to connect and secure the wiring and equipment.
Step 1 Plug all cables into the Cable Access Terminal (CAT).
Step 2 Plug the UM05 Interconnect Cable into the Universal Module (UM05).
Step 3 Plug the UM05 Switch Cable into the Universal Module (UM05).
Do not secure the CAT or UM05 permanently in place until after the connections have been tested.

10. Connect the red, brown & black wires
These are the 3 required connections for the event recorder to function. The red wire provides primary
power and must be connected to a continuous power source. The brown wire is an ignition sense. It is
used by the event recorder to perform functions such as activating the IR Illuminator (see page 13) when
the vehicle ignition is switched on. The black wire is ground.
Step 1 Connect the BLACK WIRE to negative or to a clean GROUND.
Step 2 Connect the RED WIRE to a 12V or 24V fused power source that is ALWAYS ON.
Step 3 Connect the BROWN WIRE to a 12V or 24V fused power source that is IGNITION–SWITCHED.
