use on the rover system. This adaptor serves as both a connector to the antenna and
a mount for the antenna onto the pole.
It is recommended that the radio antenna be connected to the radio prior to applying
power to the radio, although failing to do so will not cause any harm to the equipment.

Handheld Computer - GPS Receiver

The handheld computer must communicate with the rover GPS receiver in order for
the computer to control certain operations in the receiver and for the receiver to send
computed positions to the computer. This is accomplished using an RS232 computer
communication cable (Figure 3.28). The rover computer communication cable is
coiled for convenience in rover operation. The cable functions the same as the com-
puter communication cable at the base system so they can be interchanged if
needed.

The handheld computer – GPS receiver connection particulars are identical for the
base and rover systems. Please refer to the discussion on handheld computer – GPS
receiver connection under the Base System above for more details.
Now that we have reviewed the connectivity of each pole-mounted rover system com-
ponent individually, let's examine each primary component fully connected, beginning
with the Z-Xtreme receiver.
