3.0 Configuring Input Devices and Displays with MagLog Wizard.
To work with a particular hardware configuration MagLogLite™ or MagLogNT™ should be
configured accordingly. It is a highly customizable program that allows a variety of different
data presentations. However, flexibility always comes at the cost of complexity and therefore we
have endeavored to minimize configuration confusion. For this reason, we have created the
Maglog Configuration Wizard which is provided to make it easy to configure a survey. It should
be pointed out here that the wizard covers only limited number of hardware configurations that
include:
•
GPS device sending NMEA $GPGGA strings to one of PC’s serial ports
•
Geometrics magnetometers connected to another serial ports. The models supported are:
o
G-880/881 magnetometers with up to two magnetic sensors and optional pressure
transducer and altimeter.
o
G-886 / G877 family
Other devices for logging and display may be configured manually (see below). It is possible to
configure basic devices (such as the GPS and magnetometer) with the wizard and then append
more devices by hand later.
Starting Maglog Wizard.
To start wizard, select Survey Wizard from file menu:
It is recommended that you have your hardware (magnetometer and GPS) connected to the
computer and running at this time. GPS should be outputting real positions, and magnetometer
also should be running although it may not be producing real measurements at this time (it can
be on the ship’s deck). If these requirements are not met you still can proceed with
Wizard , but
there is some chance that you may encounter problems in future and have to rerun the wizard
when you are under actual survey.
