The Devices page is used to specify the ports used to communicate
with the GPS and other serial devices. The default settings are
COM1 and 4800 bits per second. When connected to the Vega
intelligent variometer, the settings should be COM1 and 38400.
Two COM devices are available (device A and device B), to al-
low, for example, one to be connected to a GPS and another to be
connected to a second device such as a variometer. If there is no
second device, set the device B port settings to the same as those
of device A.
The specific type of device can also be selected from a list in order
to enable support for devices with proprietary protocols or special
functions.
This page also has a Vario config button to display a config-
uration dialog specific to the Vega intelligent variometer. This
is described in the Vega Advanced Configuration and Data Link
Specification manual.
The Use GPS time option, if enabled sets the clock of the com-
puter to the GPS time once a fix is set. This is only necessary if
your computer does not have a real-time clock with battery backup
or your computer frequently runs out of battery power or otherwise
loses time.
