ComNav Vector G2/G2B Installation & Operation Configuration
Changing the Configuration
You may change the factory-default configuration of the Vector G2, if you wish!
• Many other output sentences can be enabled, and/or the factory-default ones
disabled, to suit the requirements of any specific installation.
• The output update rate of each enabled sentence may be changed as required.
– If a given sentence is enabled on both ports, the output rate on each port may
the same, or different, if desired.
• The port Baud rates can be changed, as required.
– There may be different Baud rates on each port, if desired.
These changes, as well as numerous other characteristics of the G2’s operation, are
done by means of a set of input commands, in “sentences” that are similar to NMEA
sentences. These “command sentences” must be sent to the G2 from a suitable “control”
device, such as the Navigator G2 GPS Compass Display System, or a PC, via the
Receive wire on the RS-232 side of the Primary Port A.
For an overview of how to configure the G2’s output sentences, and tables of the G2’s
available command sentences, see 20 through 24.
For a full description and explanation of all the G2’s command sentences, please refer to
the GPS Technical Reference manual.
Making Changes
To make changes, a suitable control device must be connected to the G2:
• a ComNav Navigator G2 GPS Compass Display
• a PC running suitable software – i.e., Hemisphere GPS’ PocketMAX PC program, or
HyperTerminal or some other “dumb terminal” program.
Using a Navigator G2
The Navigator G2 GPS Compass Display System is the easiest & best way to monitor
and control a G2.
Full instructions are in the Navigator G2 Installation & Operation Manual.
The system must be wired as shown in Figure
1, and in the G2 manual.
Using PocketMAX PC
Full instructions are in the PocketMAX User Manual.
The system must be wired as shown in Figure
3 or Figure 4.
Note: PocketMAX PC may not always run properly on some PCs. It has been
known to hang up, and/or crash the PC (especially on an older, slower PC),
and/or leave the G2 in an invalid state.
ComNav recommends that you use PocketMAX only on a fairly new PC, with a
fast CPU, lots of RAM, and “standard” COM ports.
L Caution! Please pay attention to the “… doing many things …” warning in
the first section of the PocketMAX manual!
Also, please note that PocketMAX was designed to support all of Hemisphere
GPS’ products – and so some of its features do not apply to the G2

Updated versions of PocketMAX may be released in future; please check on Hemisphere GPS’s web site. The
current version when this manual was being written was 2.2.0.
