Connecting Hardware
Handheld Computer – GPS Receiver
The optional handheld computer must communicate with the Z-Xtreme GPS
receiver to serve as an interface to the receiver. This is accomplished via an
RS232 cable such as the one shown in Figure 3.3. The computer communication
cable connects to the Z-Xtreme via one of the three serial ports on the back panel
of the receiver. These three ports are grouped together and labeled SERIAL
PORTS. Although any one of the three ports will accept the connection to the
handheld, it is recommended that the handheld be connected to port A.
Connection of the computer communication cable to the handheld is made via a
standard 9-pin serial connector. The Compaq Aero must be in its environmental
pouch in order to connect it to the Z-Xtreme receiver (Figure 3.4).
The handheld can be connected to the receiver at any time during the equipment
setup and data collection process.
