2: System Description
This section identifies the system components and describes the external interfaces
of the system.
2.1 System Components

The base unit contains the CPU, hard drive, and communication interface cards. On
the outside of the unit are the LAN and WAN ports, a GPS port, the power connector,
the power reset switch, and the status LEDs.
The power cord typically connects to the electrical system of the vehicle.
Various types of WAN antennas are available. The pad type in
common and attaches to the roof of the vehicle.
2.2 External Interfaces and Connectors
The external interfaces of the system consist primarily of the connectors and controls
on the rear panel plus the status indicators on the top of the case.
2.2.1 Rear Panel

on the rear panel of the base unit. Note that there are different build options and
configurations for the oMG 2000 and your unit may not look exactly like these.
WAN connectivity (i.e. antenna ports that the oMG uses to access a WAN) can be
provided by a pair of TNC ports labeled WAN1 and WAN2 as shown in
through RP-SMA connectors labeled WAN1-A/B and WAN2-A/B as shown in
Figure
Special Note: For best performance, please use shielded Ethernet RJ-45 cables for all installa-
tions that require LAN and WAN port cable connectivity.
