‡
COM 2 is the RT-3010 logical control port by
default. COM 1 can be configured as the
control port by using the appropriate NavCom
proprietary commands or StarUtil. However,
there are caveats to Logical / Physical port
assignments.
The Control Port is a logical input/output port
and can not share the physical port with any
other logical port. The Control Port typically
handles the most data and requires baud
rates in excess of 19.2K baud, particularly in
multi-hertz measurement and navigation
applications. Though Com 1 is physically
capable of operating at 115K baud, the
throughput from the GPS Engine to the IOP is
limited to 19.2K baud (refer to Figure 8).
Thus, the recommendation to maintain Com 2
as the Control port for multi-hertz applications.
In the Rover, the NMEA Port is an output
logical port and may share the data physical
port (non-Control) with RTCM, CMR, or NCT
RTK/UltraRTK™ input corrections. In the
Base Station, the NMEA port can not share
the data port with any RTCM, CMR, or NCT
RTK output corrections.
Refer to the Technical Reference Manual for
available port configuration settings.
