should light up when power is applied to the receiver. If using a serial interface device, look for NMEA
strings such as ZDA to scroll across the screen. If none of these things respond remove the red and
black wires from the power source and check the connections again. If in a car or Ag machine, try
turning the key on. If still having trouble refer to the power section below or call our technical support
line.
Once the receiver power is connected correctly go ahead and shut the power off. Mount the Invicta
115 and repeat the previous step.
At this point, the power is connected to the mounted receiver. The Invicta 115 will be looking for satel-
lites, which may take a few minutes. Eventually, if the antenna has a clear view of the sky, the receiver
will send data to the lightbar or other serial interface devise.
Wait for the receiver to find and track the WAAS signal, it could take 15 or more minutes before the
receiver gets the necessary almanac data from the selected WAAS satellite. This initial startup time is
necessary only during the first time the receiver is used. Once the broadcast is found the receiver will
power up and start receiving signals after about 5 seconds. If a signal is not received within about 30
minutes there could be some form of interference or the receiver may not be in the coverage area of
the selected WAAS satellite.
At this point, the receiver should be tracking satellites and generating good differential position. Start
tuning on other equipment on the machine. A device could interfere with the GPS satellites or WAAS
signals. Wait about 30 seconds after each device is turned on to see if the receiver stops tracking
satellites. Finally, start up the machine and again watch for any problems.
If after turning something on, a problem is found, try moving the antenna further away from that device.
Check that the device is functioning properly and also check its power connections. Some devices
can generate too much noise naturally or because of defective components.
Now the receiver is working with everything that could interfere. Shut everything off, mount the re-
ceiver, and route the cables. Once this is done, repeat the power up steps.
The last few steps deal with connecting the other equipment that gets data from the Invicta 115. Refer
to the manufacturer’s documentation for details such as baud rates and required messages. It is very
likely it will only be necessary to connect the interface cables to the device. The Invicta 115 is config-
ured, by default, to work with most systems without any adjustments.
All configuration and WAAS data is stored in non-volatile memory inside the Invicta 115. If it is neces-
sary to change the WAAS or GPS setups, run the receiver software to make the changes.
POWER
The Invicta 115 receiver needs DC power between 9 and 16 Volts. DC power is usually provided by
battery on the machine or via a power adapter of some type. If the unit came with an automotive
power adapter, verify that the vehicle has a negative ground system before connecting power. If the
unit came with an AC adapter, it will be necessary to only connect the adapter to an AC source.
