Fully Connected Handheld Computer

A fully connected handheld computer will have only one cable connection, no matter
which model of handheld computer is selected, as shown in Figure 3.25.

Figure 3.25 Handheld Computer with all Cables Connected

The computer communication cable is plugged into the serial port. On the TDS
Ranger, the RS232 port is on the left when viewed as shown in Figure 3.25. On the
Husky, the port is on the right when viewed as shown in Figure 3.25. This cable con-
nects the Z-Xtreme receiver to the handheld computer.

Pole-Mounted Rover System

The pole-mounted system places the GPS receiver on the rover pole along with the
other components. All components are pole-mounted, eliminating the need for a
backpack. Below is presented a list of all connections required to make the pole-
mounted rover RTK system function.

GPS Receiver - GPS Antenna

As with the base system and backpack rover system, the pole-mounted rover GPS
receiver requires an antenna to receive satellite signals. The same type of cable is
used as in the base system. The only difference will be in the length of the cable.
This makes the cables interchangeable if necessary.
The GPS receiver – GPS antenna connection particulars are identical for the base
and rover systems. Please refer to the discussion on GPS receiver – GPS antenna
connection under the Base System above for more details.
