the serial cable to COM2 of the C-Nav2050.
Connect the DB9S end to the PC (or other
controller device).
2. Connect the supplied LEMO 7-pin connector of
the dual data cable to COM1 of the C-Nav2050.
Connect the DB9 ends as required. A typical
setup could include: NMEA data-out to the
Navigation or DP (Dynamic Positioning) System,
and data-in from a 3rd party connection input
(RTCM)

Technical Data Declaration (Jan 1997)
The Contractor, C&C Technologies, Inc.hereby
declares that, to the best of its knowledge and belief,
the technical data delivered herewith under Government
contract (and subcontracts, if appropriate) are complete,
accurate, and comply with the requirements of the
contract concerning such technical data.
Global Positioning System
Selective availability (S/A code) was disabled on 02
May 2000 at 04:05 UTC. The United States government
has stated that present GPS users use the available
signals at their own risk. The US Government may at
any time end or change operation of these satellites
without warning.
The U.S. Department of Commerce Limit Requirements
state that all exportable GPS products contain
performance limitations so that they cannot be used to
threaten the security of the United States.
Access to satellite measurements and navigation
results will be limited from display and recordable output
when predetermined values of velocity and altitude are
exceeded. These threshold values are far in excess of
the normal and expected operational parameters of the
C-Nav2050 GPS Receiver.
