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.
2. Prepare the External DC power cable. One end of the exter-
nal DC power cable fits into the terminal’s DC Power connec-
tor. The other end has no connector.
Installation Note: Power Sources
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 directly to
a vehicle battery. In this case, Symbol recommends that you use an in-line
fuse holder and 5A slow-blow fuse. The fuse protects your vehicle from an
electrical short on the power cable.
