Three cables will come from outside into the location where the Core Module will be
installed; the DF antenna coaxial cable, the DF antenna control cable, and the radio modem
coaxial cable. Connect these cables to the proper connectors on the core module.
Connect the GPS and Self-Test generator cables. Position the GPS where it will receive
signals from the GPS satellites. If this is not possible then do not connect the GPS receiver.
Connect the Self-Test Generator cables to the core module and the Self-Test Generator.
Position the Self-Test Generator 20 - 250 feet from the direction finder antenna in an area
where it is not exposed to the elements. Instructions on using the Self-Test Generator can be
found in the MPT Software Users Guide.
If you are using an external scan receiver connect the external speaker output of the receiver
to the AUX IN connector and connect the audio output connector to the line input of the
computer using the 1/8 inch stereo cable supplied with the unit. If you purchased a
computer with the DDF7011, it will come furnished with an iMic (USB-to-Audio) converter
that has a line input. If your computer does not have a line input and you are going to use an
external scan receiver then you will need to purchase an audio interface.
The radio modem is used to communicate with other Doppler radio direction finders in the
event that the other direction finders cannot be networked on an Ethernet (IP) network. Each
radio modem has four preprogrammed channels. Set all the direction finders on the radio
modem network to the same channel.
The Ethernet connection can be connected directly to the computer using a crossover cable
or if being used remote it can be connected to a switch or hub using a standard Ethernet
cable.
The unit is powered using 12 volts. The DDF7011 without a laptop draws requires 13 watts. If
a laptop is connected to the laptop power supply the unit can draw up to 100 watts
depending on the battery's level of charge.
Once all the connections are made, power up the unit and start the software.
