Using either the field application software or the front panel of the receiver, set
the base receiver to RTK base mode.
Receiver is configured as RTK base
Go to step 4 below.
Step 4. Is Receiver Set to Output RTK Base Data on Port B?
The port set in the GPS receiver for output of RTK base data must be the same port to
which the base radio is connected. The base radio should currently be connected to
the serial port labeled 'B' on the back of the Z-Max. Use the field application software
or the front panel of the receiver to verify that port B is set as the output port for RTK
base data.
Receiver not set
1. Set the receiver to output RTK base data on port B.
Using either the field application software or the front panel of the receiver, set
the base receiver to output RTK base data on port B.
Receiver set
Go to step 5 below.
Step 5. Base coordinates entered correctly into base receiver?
The base GPS receiver compares the position it computes for its location to the
position entered by the user as the base position. If the two sets of coordinates differ
by more than 500 meters, the base receiver will not output RTK base data. Use the
field application software or the front panel of the Z-Max to verify the coordinates
entered for the base position.
Coordinates not entered correctly
1. Set the correct base system position. Using either the field application
software or the front panel of the receiver, set the correct base receiver position.
Coordinates entered correctly
Go to step 6 below.
Step 6. Is base receiver tracking satellites?
The base GPS receiver must be tracking satellites in order to collect the data required
for the radio to transmit. If the base receiver is not tracking at least 4 healthy satellites,
no data will be sent to the radio. Use either the Power/SV LED on the front panel of
