These units, in combination with an antenna, provide satellite 
connectivity for multiple local area network (LAN) hosts through 
one DIRECWAY System. All the necessary software resides on 
the Gateway, which serves as the router. Because the software is 
on the Gateway, there is no need for a computer to run client 
software, unlike previous versions of DIRECWAY.
Figure 1 illustrates the functionality of the DW4020 within a 
DIRECWAY network. Note that the DW4020 is independent of 
operating platforms. It can also be used with devices other than 
computers, such as point-of-sale (POS) terminals or credit 
verification devices.
Characteristics and 
identification of 
equipment 
The part number label is located on the rear of the unit.
Table 1 shows the hardware characteristics of the DW4020.
Table 2 shows the physical characteristics of the unit.
Table 3 shows the cable requirements for the unit. The cable 
requirements are the same regardless of the type of antenna used.
