Brightness Adjustment; Data Link - Triadis Engineering Glide Computer and Navigation System Owner's Manual

2.3 Brightness adjustment

2.4 Data link

Com A Device : Altair Pro
The brightness of the LCD screen is adjustable via a backlight, and
can be software controlled from the menu system in XCSoar from
the menu:
DISPLAY Bright
This allows the automatic backlight to be enabled or disabled, as
well as manual adjustment and bias of the automatic backlight.
When automatic backlight is enabled, the brightness field adjusts
the automatic backlight system; otherwise the brightness field ad-
justs the backlight directly.
The purpose of the adjustment in automatic backlight mode is to
help the system adapt to the pilot's preferences.
Note that the LCD back-light which is controlled by the bright-
ness adjustment, has a significant effect on power consumption. It
is recommended that if needing to conserve battery, to turn bright-
ness up to the lowest level at which it is comfortable.
For Altair Pro systems, the maximum brightness is limited when
using backup battery in order to extend the duration that Altair can
operate.
Three data links are available in Altair. Two external serial ports
are located at PORT A. The first serial port (COM1) is used to con-
nect to an external GPS source, intelligent variometer, or FLARM.
The second serial port (COM2) can be connected to an aircraft ra-
dio in order to be able to display and control the radio frequency
via Altair. A third serial port (COM3) is an internal data link be-
tween Altair's computer and the internal IGC logger.
Recommended serial settings in XCSoar for Altair Pro and Vega
installations are to use Altair Pro's internal GPS as the primary
GPS source, and Vega/FLARM as the secondary source:
