2. Operation
The RV-M7 GX operates in a number of different “GPS Modes”, each mode
specific to the application it is being used in. The mode of operation is set with one
simple command, the GPS x command. The main GPS modes of operation are:
1)Transponder: Periodically transmits position and status over the UHF radio. Its
radio receiver is disabled reducing current draw. It cannot
receive messages, data, or locating information from other RV-
M7 GX transponders. 4800bps serial port.
2)RavTrack PC: Connect the RV-M7 GX to a personal computer running
RavTrack PC (or other PC software) to view a map showing
location, status, log movement, set alerts, and make reports from
the data. 38400bps serial port.
3)Radar Display: Connect RV-M7 GX to a marine plotter or radar display, and
icons will appear on the display showing the location of all other
RV-M7 GX radios in the system. 38400bps serial port.
4)GPS display: Connect RV-M7 GX to a hand-held or mobile GPS, and icons will
appear on the display showing the location of all other RV-M7
GX radios in the system. 4800bps serial port.
12)Mobile Data: Outputs WPL messages for position, and transmits and
receives data. Connect the M7 GX to a hand-held or mobile
GPS, and icons will appear on the display showing the location
of all other RV-M7 GX radios in the system. Data sent into the
RS232 port will be transmitted over-the-air in the proper time-
slot, and may be received with other M7’s.
The different modes change the operation of the RV-M7 GX in a number of ways.
The GPS X command is a “macro” that sets a host of various parameters within the
M7 to configure it to operate in the desired way. The serial-port data rate is set, the
types of NMEA messages it wills send out or accept is set, as will as how the
internal UHF radio is used. The table below summarizes the 4 standard GPS
modes, as well as listing other specialized operation modes that the M7 GX
supports.
GPS mode 2 is the factory default mode.
