Change the GPS Source
To change the GPS source after the network has been configured, open the
Network Source Setup dialog box to change the GPS sources at any time.
Network settings are saved even after the unit is powered off.
If the control head cannot detect the set GPS receiver, the control head will
display an error message so that you can reset the GPS source as follows:
• If the shared GPS receiver is not detected, the control head will
switch automatically to the local GPS receiver. Follow the on-screen
instructions to permanently save the local GPS receiver as the selected
source.
• If the local GPS receiver is not detected, the GPS data will flash. If
there isn't data displayed in the digital readout box, the source has
been lost. See Select a GPS Source to select another GPS Receiver in
the network.
If the control head cannot detect the shared GPS Receiver set in the network, follow the
on-screen instructions to change the GPS source. Press the LEFT Cursor key to select No,
or press the RIGHT Cursor key to select Yes.
