Base radio powered up
Go to step 2 below.
Step 2. Is the Base Radio Connected to the GPS Receiver?
In order for the base radio to transmit data, it must receive the data from the base
receiver. To determine if the radio is connected to the receiver, look for a cable
connecting the two components.
Radio not connected to receiver
1. Connect the base radio to the GPS receiver.
2. On the back panel of the Z-Max, connect the radio cable to port B.
3. Connect the radio cable to the radio connector labeled DATA/PWR or SERIAL.
Radio connected to receiver
1. Ensure proper connection
2. Ensure that the radio cable is connected to port B on the back panel of the
receiver.
3. Ensure the connection between the receiver and the radio is well-seated.
Go to step 3 if the problem is not yet resolved.
Step 3. Is the Base GPS Receiver Set to Function as RTK Base?
If the base receiver is not set to RTK base mode, it will not send raw data to the serial
port for transmission by the radio. Use the field application software or front panel of
the Z-Max to determine if the receiver is set to RTK base mode.
Receiver not configured as RTK base
1. Set receiver to RTK base mode.
