Connectivity
panel of the radio and labeled SERIAL .
It is recommended that the radio be connected to the receiver prior to powering up the
receiver. This will ensure a clean power up of the radio since, with the spread-spec-
trum radios, the receiver supplies power to the radio through this connection.
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, as shown in Figure 3.21. The rover computer communication
cable is coiled for convenience in rover operation. The cable functions the same as
the computer communication cable at the base system so they can be interchanged if
needed.
