8. Optional: install a vehicle-
mounted antenna. Some-
times you can improve wire-
less communication by
mounting an external anten-
na onto the vehicle. Symbol
has several different external
antennas available. Contact
your Support Representative
for more information.
To connect an external vehi-
cle-mounted antenna:
a. Secure the external an-
tenna to an appropriate
location on the vehicle.
b. Connect one end of a coaxial cable to the terminal’s An-
tenna Connector. Connect the other end to the vehicle-
mounted antenna. Make the coaxial cable as short as
possible to minimize signal loss.
Providing Power: Vehicle Installations
VRC 6940 terminals can be powered by:
•
12V or 24V gas-powered vehicles
•
battery-powered vehicles, up to 60 volts
To provide power to a vehicle-installed VRC 6940:
1. Locate your vehicle’s power source. Always connect a VRC
6940 terminal to a continuous or unswitched power source.
Note:
The ideal location for connecting a VRC 6940 External
DC power cable would be a fused power source on the
vehicle’s power distribution panel. If no fused power
source is available, you can connect the terminal di-
rectly to a vehicle battery. In this case, Symbol recom-
mends that you use an in-line fuse holder and 5A slow-
