Interfacing to other devices requires slightly different pin/wire connec-
tions. For example, use the following table to enable the 941X to com-
municate with a Yeoman electronic chart plotter.

Table 8—Yeoman Electronic Plotter Setup with 941X
If your 941X is not equipped with an internal beacon receiver, you can
interface it with an external Northstar model 8800, 8401 or 8400 bea-
con receiver, or other source of differential corrections. As described on
page 74, differential corrections greatly enhance the accuracy of GPS by
improving your position fixes to accuracy of 2-5 meters in most cases.
To take advantage of this extra level of precision, connect the Northstar
beacon receiver to the 941X's RS-232
