Base/Rover Setup
Base/Rover Setup
Immediately a scan of available Bluetooth devices will
begin and a few seconds later will be completed. If a base
station is found that has been previously used, J-Field will
automatically connect to it. If not, you will be presented
with a list and must choose the device intended to be used
as the Base receiver and tap
Connect
.
Once the Bluetooth connection has been initiated, it will
take a few seconds before it has completed. During that
interim few seconds, your screen may appear like what is
shown on the right.
Once the existing Base and radio parameters have been
retrieved the screen should look similar to this. The Rover
profile radio parameters are displayed on the left panel while
the current Base coordinate is displayed on the right.
Radio
parameters displayed in red indicate that there is a different
value between the Base and Rover profile.
Use
From Base
to
update the Rover profile to the parameters from the Base or
use
To Base
to send the Rover radio parameters to the Base
before starting the Base.
Tapping the left panel opens the screen to configure the
radio parameters. “RTCM 3.0 Min”
Format
should be used
to minimize the correction data that must be sent through
the radio.
To use
5 Hz BEAST MODE
the
Broadcast Period
must be
changed to
0.2 seconds
or
Use Data UpSampling
must
be enabled in the
Advanced Setup
menu (discussed at the
end of this section). It is important to note that increasing
the
Broadcast Period
, increases the battery consumption
of the radio as well as the heat generation inside it. With
the HPT435BT you may need to use the modem fan when
broadcasting with an output power greater than 4 watts
with 5 Hz corrections, depending upon the ambient
temperature.
Data UpSampling
is now preferred over 5
Hz corrections as it increases battery life and range of the
radios and decreases the heat generated from the radios.
The
Base ID
field limits the Rover from receiving corrections
if the Base and Rover profiles do not have the same
Base ID.
It can be left at its default value of 0.
Transmit L2C
is always enabled. If for some reason it is not
checked, it will become enabled automatically when the
Base is started with

To configure the UHF or FH915 parameters tap the
UHF

button.
