Installation and Interfacing

Page 123

If you presently own a Northstar 800 series loran, you may connect it to
your 941X to serve as an ideal source of Loran-C TDs and previously-
stored waypoint locations. Use the appropriate pin/wire connections and
the 800’s setup sequence, each listed below, to initialize the data output
to be received by the 941X. Port 1 or Port 2 of the 941X, or A or B of the
800, may be used. Wire colors refer to the 941X’s interface cable.
