Communication
So far you have installed and interconnected the components of the F180R System Inertial
Attitude and Positioning System so that they are ready for use. This chapter of the manual
describes the various interface options and data output formats that you may use with the
F180R System.
The F180R System system communicates with the controlling PC and with external equipment
over various protocols using five interface ports: Ethernet, COM1, COM2, COM3 and PPS:
For control, configuration,
acquisition and QC of the
F180R System system using
the supplied Windows–based
application software
MCOM binary data output string
Configurable ports
outputting data at rates up to
115200 baud
Attitude data using the TSS1,
EM1000, EM3000 and TSS
HHRPdata strings
NMEA data strings for reporting
of position, fix, heading,
velocity, date, time and error
statistic using NMEA GGA, GGK,
GSA, GSV, GST, HDT, PASHR,
PPS, PRDID, PTCF, RMC, ROT,
UTC, VTG and ZDA strings
MCOM binary data output string
Differential correction input
at rates up to 115200 baud
The system also supplies a 1
pulse per second (PPS)
output synchronised with
GPS time
3.1.1 Ethernet
The Ethernet connection allows you to make maximum use of the F180R System system. The
system outputs data using a UDP (User Datagram Protocol) broadcast on port 3000 that allows
all PCs connected to the network to receive the transmitted MCOM data. It provides
significantly greater data transfer capacity than a serial RS232 connection. To receive data from
the F180R System system on a PC, the PC must have an Ethernet card fitted and be connected
