Installing the GPS Antenna
1. Mount the antenna where it has a good view of the sky. It should see at least
⁰
90 of the sky. For example, if you mounted the AirLink device in a vehicle,
you could mount the GPS antenna on the roof, the dashboard, or the rear
panel, as shown in
Figure 2-8: Mounting the antennas in a car or truck
2. Connect the antenna cable to the GPS/Diversity antenna connector.

Connecting the LS300

Note: If the antenna is located far away from the device, keep the cables as short as
possible to prevent the loss of antenna gain. Route the cables so that they are protected
from damage and will not be snagged or pulled on. There should be no binding or sharp
corners in the cable routing. Excess cabling should be bundled and tied off. Make sure that
the cables are secured so that their weight will not loosen the connector from the device
over time.
1. Connect the RF antenna to the antenna connector.
2. If used, connect either a GPS antenna or a diversity RF antenna to the GPS/
Diversity antenna connector.
3. Attach a laptop to the device with the Ethernet cable.
4. If used, attach a device or computer to the RS-232 port.
5. Connect the power cable to the device, and if used, to the external devices to
be controlled/monitored.
The device starts automatically, as indicated by the flashing LEDs.
Note: For details about the power connector, see
page 15. The battery connector cable should be no longer than 10 feet (3 meters).
