2.1.
The outlook of mainframe
The mainframe has an almost cylindrical shape, with a base larger than the
height. There are three parts: an upper cap, a rubber loop and the main
structure. The upper cap protects the GNSS antenna placed inside.
The rubber loop has the function of softening possible shocks or falls. In the
front of the main structure there are 2 keys and 9 lights, on the bottom side
there is one slot for the built-in radio and GSM/GPRS module, and one for the
battery and SIM card.
All the others components of the receiver (Bluetooth device, main board, OEM
board, etc.) are contained inside the main structure.

Interfaces
The mainframe interfaces are shown in Fig. 2.3: the left port (five pins LEMO)
is used for external power supply and external radio connection, the right port
(seven pins LEMO) is used for data transferring between receiver and
computer or between receiver and the handheld. Near the radio and
GSM/GPRS module there are radio and GSM/GPRS antenna interfaces.
