Coax Cables
The GeoSteer Control Unit is connected to the GeoDock with one or two coax cables depending on the options that have been
ordered. One of the coax cables connects the TNC connector on the GeoDock GPS antenna to the TNC connector on the
GeoSteer Control Unit. If a cell modem is installed on the GeoSteer Control Unit, the second coax cable connects the Reverse
TNC connector from the Cell Modem Antenna on the GeoDock to the SMA connector on the GeoSteer Control Unit. Figure
8-15 and Figure 8-16 show the connectors on the GeoSteer Control Unit and GeoDock that need to be connected.
Note: Do not use a tool to tighten the coax connectors on either end of the coax cable. Hand tighten only or the connectors
could be damaged.
