Chapter 4 Configuration
The RT-3020 GPS sensor has a rich interface and
detailed control language, which allows each unit to
be tailored specifically to the required application.
Factory Default Settings
By factory default COM 2 is designated as the Control
Port. The Control Port manages the full functionality of
the RT-3020.
COM 1 by factory default is designated as
the data port. By factory default this port handles the
non-NavCom proprietary messages that are input
and/or output to/from the receiver. By factory default
NMEA message GGA data is scheduled for output from
COM 1 at 1Hz. The baud rate at which COM 1 and
COM 2 communicates is factory defaulted to 19.2k
Baud. This baud rate can be changed to accommodate
faster data rates.
The standard factory configuration for the RT-3020
allows for the basic operation of the system. The control
port factory default NavCom Proprietary Message
Blocks output is described in Table 6. These message
blocks afford the novice or seasoned
GPS user the best
opportunity to get up and surveying in a minimal
period of time.
The output data rate for the factory default message
blocks is described in Table 6 and will remain at that
rate until the user specifies otherwise by issuing the
appropriate NavCom
Proprietary command .
