7.4 CONFIGURATION
1.
Any parameters, changed in any mode of SETUP, return to the default settings when
the system is next switched on. The CONFIG mode may be used to change the default
settings so that the ADTS 405 Mk2 powers-up in a specified state. Most SETUP
parameters are also available in CONFIG; other parameters are only available in
CONFIG.
2.
Some parameters, changed in setup mode, can be locked in CONFIG preventing
access. For example, a system used in a servicing procedure for a specific aircraft type
can be set to power-up with a specific set of limits that must not be changed. The
setup menus can also be locked out or access restricted preventing changes to
operating parameters.
7.4.1 Procedure
a.
Holding down
F1
then pressing
SETUP
causes the system to enter CONFIG mode.
CONFIG may be password protected using a four digit PIN. If PIN protected, the
display prompts for entry of the PIN. Press each digit of the PIN in turn (ENTER is not
required) as each digit is entered, an asterisk appears. If an incorrect PIN is entered,
the complete PIN is requested again.
b.
When the correct PIN is entered, the CONFIG menu appears.
c.
The PIN may be changed using CONFIG,
-000
.
d.
To use the configuration menu, press the appropriate function key to select the
required menu item. To configure a parameter key, enter configuration menu then
press the required parameter key. Each parameter key configuration provides
changes to the normal user mode function and to the settings available in the setup
menu.
e.
Once a parameter has been changed in configuration, use
CLEAR/QUIT
to return to
the previous menu. After all required key parameters have been changed, repeatedly
press
CLEAR/QUIT
until the display shows the normal operating mode.
7.4.2 Functions
In the following section, each description of a CONFIG function is headed by the menu/key
sequence required to select it. Intermediate menus are not described. Many of the functions
are equivalent to the setup functions; refer to SETUP for the details of the function.
7.4.3 CONFIG, [UNITS]
This function allows the default units to be configured.
1.
The default [AERONAUTICAL] units are used at power-up for the altitude (and
airspeed) display. The default units are also used for the limits entry in CONFIG and
entry of any altitude or airspeed related functions in SETUP or CONFIG e.g., airfield
altitude or altitude correction.
2.
The default [PRESSURE] units are used for limits entry in CONFIG and entry of any
pressure values in SETUP or CONFIG.
